I recently went to a Rock Crawling Competition here in Crozet, VA. It was an event that no disco would have a chance, but I noticed that almost every rig/buggy had ARB air lockers. Why would they not run a detroit...at least in the rear? Just curious.

Some rock buggies employ cutting brakes to make tighter turns (you are marked down for having to use reverse); these absolutely will not work with a Detroit locker.

As far as cheap goes...a Detroit is usually several hundred dollars cheaper than an ARB.

James, I've noticed a distinct difference in my ability to do well in trials courses after the Detroit locker. It's great when you have a steep section, but it's overall impact has been negative for that style of competition.

The Detroit propels you forward, and does not allow you to turn as tightly. On certain surfaces, it kicks your ass sideways (as does an ARB, except that you can turn the ARB off). In rocks, particular the serious rocks you're talking about, I think you need all the different traction options you can get.

Yeah, I was close to a lot of those obstacles and you could see/hear those guys turning their lockers on/off depending on the situation, sometimes in quick succession ...on...off...on..off. That was a very educational event, in many ways.

I like the ARB, but I have seen many fail. Back when I ran Hummer H1's people would break them all the time. On jeeps I have seen people have trouble getting them to lock up. Wires break or come loose. Air lines come loose, break, get ripped off... Or the pump just stops working. At this point seeing the new Detroit Elec. locker I would hold off on buying an ARB and see if it will be avalible for the Rovers. That way if something happens to the locking part of the locker you at least have limited slip, the way I understand it. I think I saw the new Detroit for Dana 44's right at about 800.00.

Come on man, get serious. That's like saying a Yugo is better than a Discovery when AMR-2010 gives out and the Disco is stuck in park.

And I'm calling out the "a compressor and air line and switch are too complicated" crowd too. Come on, you know who you are... By your logic, we should all have hand-cranks sticking out from our grills since a key, ignition, starter, etc are too complicated.

I seriously considered picking up a local 3rd with a Detroit and putting my ARB up front, but I couldn't think of any instance where a Detroit in the rear is better than an ARB. I can only think of the downfalls: ratcheting, knocking, banging, sliding my ass sideways, loss of maneuverability in tight spots, etc.

I got into some really hairy stuff this past weekend, and I must have clicked that ARB on & off a hundred times to thread the needle. I'll post some pics soon enough.

So, I'm still waiting...Please give me one scenario where a Detroit is better than an ARB...

I like the electric locker idea. I run arb and they have been very reliable so far. true a line could break but just like everything our on your vehicle, you need to know how to do trail repairs. They are very simple to repair.

Blue, stop bitchin'

Of course ARB is superior as far as concept goes.
However, the fact that you got lucky with a previously installed ARB doesn't say anything about the setup's reliability in general.

It's just unfortunate circumstances that the choice of selectable lockers is limited to ARB for a Rover application. There's plenty of super-reliable selectable lockers - for instance, hydraulically-operated lockers on Pinzgauers - but none made it to the Rovers.

ARB failures I've seen over a few years of my wheeling outnumber by large and far breakages of Detroits and even cheaper lunchbox lockers. A Detroit is simply there when you need it (and a bit when you don't) - but it's not like you're cross-axled at a 30-degree slope punching the goddamn button waiting for the crap to kick in.

Discussions about lockers are futile. Blue, it doesn't matter a hill of beans to me if you run an ARB or Detroit. I'd gladly run either. I went with a Detroit in the back because I could have it installed and shipped back to me since I don't have the tools or expertise locally to do it locally.

I might put an ARB in the front. I might use a truetrac. Both are viable and both work just fine.

In my system of values about a locker, I tend to think that reliability is more important than operation efficiency. Others may feel differently, and that's fine. My operation environment offroad tends to make the case not having air lines hanging. If I was running in the rocks, I might feel differently.

Install what you like and be happy. You don't need anyone elses opinion on how to spend your money.

The ARB compressor really sucks big time.
I bought one about a year ago, right before i was planning on buying a ARB locker. So i put the compressor in and im testing it out. A while later i was playing around with it..it was running all fine..and it just suddenly died..So i decided not to get an ARB, because i didnt want to depend on this POS. Sure, i could have bought another compressor...but why spend more $$$???

Blue,
You said :
"I can only think of the downfalls: ratcheting, knocking, banging, sliding my ass sideways, loss of maneuverability in tight spots, etc. "

How come i havent experienced this ratcheting/knocking/banging/sliding my ass sideways? Sure, it will slid the rear end sideways off road...but all locker will do that.

You also said :
"but I couldn't think of any instance where a Detroit in the rear is better than an ARB."

Well thats cause you haven't owned one...sounds like a personal problem to me :-) :-) :-)

Funny, I have yet to need a locker and I seem to be able to go where others aren't able to. (Go ahead Perrone, tell me I'm WRONG)

In my case, I think I'd rather have a winch to get me out, rather than a locker to get me stuck.

I sure hope this doesn't turn into a multi-page locker bash-a-thon, although watching the crashing and burning is entertaining until somebody gets hurt.

I'm still waiting...Please give me one scenario where a Detroit is better than an ARB...

So far we've got:
-wish there was an electric locker available
-well its because i have one andd its better.
-wish there were hydraulically-operated lockers available
-A Detroit is simply there when you need it (and a bit when you don't) - but it's not like you're cross-axled at a 30-degree slope punching the goddamn button waiting for the crap to kick in.
-reliability is more important than operation efficiency (then why the hell are you driving a Rover, Perrone?)
-The ARB compressor really sucks big time.
I bought one about a year ago, right before i was planning on buying a ARB locker.
-How come i havent experienced this ratcheting/knocking/banging/sliding my ass sideways? Sure, it will slid the rear end sideways off road...but all locker will do that. (not if you turn it off, Will)

So what's the Detroit have over ARB? Does it lock any better? Does it give you better traction? Is it stronger? Is it better on straight uphills? In tight spots? In mud? Rocks? Snow? Ice? If you're "lucky" like dumb old me and have an ARB that works, is the Detroit still better? If yes, why? If no, why not?

Blue,

I gave you an HONEST and fair answer. I did not offer any antagonism or sarcasm in my post. I simply told you why I made my own choice.

Operationally the Detroit offers nothing over the ARB. When they are both working, they both do a remarkable job. The ARB offers the ability to install in the front in our trucks which the Detroit doesn't. The Detroit doesn't appear to be any stronger.

The Detroit offers only two advantages as far as I can tell.

1. It's cheaper
2. It is less susceptible to common failures.

If these two things are unimportant to a buyer then they are both similarly acceptable. If one wants to run open or wants to install in the front, the ARB is the only logical choice of the two.

Good luck with your ARB's Blue.

-P

From what I have *heard*...YES, the detroit is actually stronger.

Here is why the detroit is better...FOR ME:
1)Cost
2)more simple
3)easier on the trail (for me...worrying about turning my lockers on and off on the trail is just one more thing to worry about)
4)Its more reliable :-)

But then again...I'm just a kid, so what do I know? ;)

I like the buttons. And the hiss it makes and on real quiet nights you can hear a slight ping as it engages. Love the arb.

I'm really just trying to decide if the simpleness of the detroit (no compressor, switches, airlines) outweighs it's lack of selectability. There would have to be something in the detroit's plus column besides "locks/unlocks on it's own".

How often are these detroits locked up when you wish it was unlocked? I experimented with my ARB this past weekend and left it locked while I was trying to get through some really tight, off camber spots. The truck really crabbed downslope when I left it locked (so much so that I lost my line a few times and had to bail). What do you do in these situations if you are running a Detroit? Does the driver have any say in when it's locked or unlocked? On a lot of these trails, open diff is simply NOT an option.

I was wondering what was taking Kyle so long to respond!

I kind of agree with Blue, but that's me. If something in my "ARB System" is not working on the trail, generally I can track it down and fix it within a few minutes. But then again I like to fix things, thus owning a Rover:-)

Perrone beat you to that standard response, Kyle. Come on, you can do better...

Why is that when you ask what makes the Detroit good, all you ever hear is "because ARB sucks"? What kind of an answer is that? What makes you a good person? Because everyone else is an asshole?

Enoch put forth some constructive info. Perrone has hit on the front/rear axle possibilities (I'm only talking about the rear axle though), and both Perrone and Will have brought up the point that detroit is cheap. But again, what's the detroit have going for it? Take ARB out of the picture and sell me a detroit.

Blue , you asked for one scenario. Youa re trying to throw out the one scenario now because you dont like how obvious it is. Well , it being so obvious is exactly the point...
How bout the ARB being harder on axles and related when you have to make a turn imediately after an obstacle and its bound up and wont unlock ? How bout the rubber seals that make it all work ?? Dont give me your hand crank bullshit , thats just going to the other end of the spectrum to try and make an argument. With the evils that we already have you simply have to strive to keep things simple. Doesnt always work out but the theory has been around since the dawn of time and seems to still work. You want to argue that now ?
As far as steering concerns , well , I havnt run into any. But if I did , I am imagining that big round thing that sits in front of the drivers seat could take care of it. Marvelous invention that thing is and it has so many uses now adays....

Reliability
Stronger than ARB
easier to install
Cost

I have the Detroit in the rear of my truck and love it. Yes ARB would be a litter nicer but you are not comparing apples to apples. Detroit vs. Loc-Right or ARB vs. Detroit Elec. locker is a better comparison. There either way the Detroit wins.

LOL Kyle. You've still got the "Detroit is good because ARB sucks" bullshit argument going. Although you're making headway with How bout the ARB being harder on axles and related when you have to make a turn imediately after an obstacle and its bound up and wont unlock ? Does the ARB really bind up? I didn't know that. If Detroit doesn't bind whereas ARB does, then that is a check mark in the Detroit's plus column. Stress on my stock axles definitely weighs on my mind.

and I've agreed with you on this point in the past, and I still do:
With the evils that we already have you simply have to strive to keep things simple. Doesnt always work out but the theory has been around since the dawn of time and seems to still work. You want to argue that now ?
I'm not about to argue against KISS, but is that really the Detroit's biggest selling point? I mean REALLY?

and I'm not sure I get you here
As far as steering concerns , well , I havnt run into any. But if I did , I am imagining that big round thing that sits in front of the drivers seat could take care of it. Marvelous invention that thing is and it has so many uses now adays....
Are you saying that your Detroit hasn't ever crabbed your ass end sideways, but if it did you'd just use the steering wheel to correct? I'll await confirmation of your point before I rip on that one.

Nope , I cant say THE DETROIT has ever crabbed me sideways. Have I crabbed sideways ? Fucking A , in that truck and in many others that had no lockers at all. But that is what the steering wheel is for. Perhaps in AZ you boys arent hip on that yet. I can go into it further by telling you other things it does but those were pretty much add ons to an already perfect design.. You seeing the point here ? I mean ,I am sure we could come up with some simply amazing fucking electronic air operated steering , but why ? And whats the cost for failure ? The steering wheel has been getting the job done for years just the way it is..
As far as locking and unlocking. Well , the ARB is actually an air actuated spool. WHen it has tension on it , it stays locked until you can get a little slop in the driveline for it to drop out. When making tight turns at the top of an obstacle this can be a pain in the ass and is certainly harder on driveline parts.
But this is all bullshit really. The main thing is that thing you dont wanna talk about. If its not important , then having a locker at all is not important. If the fucking thing doesnt work one time when you needed it then throw that fucking thing in the garbage. So why do you want a locker Blue ? If it doesnt lock for you at some point do you still want it ? And is it really a locker at that point ? Or is it simply an open diff like the one you replaced it with ? You might not like the argument but thats the way it is. The detroit is a more reliable option reliable as in , its fucking locked when you need it locked. If it wasnt important , I wouldnt waste the money on a locker at all... Niether would you..

Kyle,

Off camber on mud or wet rocks. That is a bad combination for a locked rear end. Of cours it is bad anyway but even worse locked up. I would want a locker that doesn't work in that situation.

Brian , on wet rocks you are sliding anyway , open or locked. They key is to not spin , take the right line and take it so that you are safe if slipping does occur... And use that round thing alot.... I am telling you , it really comes in handy..

As far as locking and unlocking. Well , the ARB is actually an air actuated spool. WHen it has tension on it , it stays locked until you can get a little slop in the driveline for it to drop out. When making tight turns at the top of an obstacle this can be a pain in the ass and is certainly harder on driveline parts.

Now this is what I'm looking for. Substantive info. For the record, how does the Detroit mechanism operate relative to ARB's spool? From what I understand, the Detroit is normally in locked mode until it senses the need to differentiate via clutch mechanisms. Is the Detroit then really less likely to bind? What's with all the reports of ratcheting or clunking? Just improper installs preventing the Detroit from completely releasing? Also, how can I induce a little driveline slop to ensure that my ARB has the opportunity to disengage? Let off the gas and let the Disco roll back a couple inches (which of course may not be feasible in some cases)?

As far as the wonders of the steering wheel go, I'm talking about tight spots where a couple inches of slide to the left or right on steep, off-camber gravel means goodbye doors or drop into the big hole (ask me how I know :-)).

Hmmm, an insight into Brian's driving style....

That would explain allot :-)

Well ,as far as I know the "Detroit locker" is still assembled by hand. THis introduces the human factor and subsequently the friday factor. In short , they are all not the same and some come out of the box fucked up. People think they are too tight when in reality they are setup too loose. This will make them drag tires and bang and carry on. I had one and sent it back and got another that was just fine. SO its really nothing to do with the install but rather the assembly of the diff itself. Its not technically broken , just not setup optimally.
The funny thing about shit winding up is that you have to back up to the point that it started winding to get the tension off of it. In some cases thats right back in the middle of the obstacle. I think you can see the issue in that.
You may forget that I have both here. One with ARB front and rear and one with the Detroit True trac combo. The ARB truck certainly drives better on the road then the detroited Disco but there have been times when the damn thing wouldnt work and had to be fucked with ( I dont go to the trails to work on the trucks) and I see it bucking and hopping when its still bound after clearing an obstacle. Most times you can just pat the throttle to make them drop out but not always. If its good and wound up you simply have to ride it out and get out of the turn. The detroit has a mechansim that knocks it out (In most cases) when one wheel overrides the other. No , this isnt gonna drop out all the time but I find that it does fairly often and I dont have that same degree of winding going on.

So unlocking CDL will not permit the Detroit to lock? Drive power will just blow out through the front shaft?

Blue, are you saying the idea of the spool not unlocking under load never occured to you? Ever notice that the little six-legged light on the dash doesn't go off until you hit the top of the hill?

i wish my head was made outta plywood.... it seems to be just as dumb, but not as stout mechanically. one particular thing that beats me is that you know all the fucking answers and keep the fan spinning. and i bet if you didn't get your Disco with the ARB installed already, you'd have a nice'n'simple'n'cheap Detroit in it.

OTOH... it's April's Fools' Day.

Im thinking....weld the spider gears and install a manual locking (see get out and turn the hub) hub on both sides. Best of both worlds, it is locked when you need it and when you don't you can just get out and unlock it. Might slow things down a bit but it sure would be reliable.

btw....I heard that Dave Lucus:-)

I am drivable now I think I have actually driven close to 500 miles on the road and one super easy 4x4 trail. I do beleive that within a month or so I will be totally transformed adn I wont be breaking so much stuff. I am getting the itch though, it has been at least 2 months since I have broken anything and I am sure my truck is feeling neglected.

Damn, this post sure rolled on. From what I've read, the ARB wins slightly. The strength of the lockers is hard to debate. What makes one stronger? I've never seen the ARB break or fail in the diff area. Nor have I seen the Detroit break. I have seen a detroit refuse to lock up though. Granted, air lines, electrics, and pump could fail, but if the line is routed well, the line is safe. If the pump is serviced properly, it is safe (mine did NOT fail even when under water). The electrics can fail but so can all the electrics in your truck. My ARB stopped working for a short time on the trail and I for once, was concerned about the ARB. I popped the hood and found the wire pulled off from the battery. I reconnected and the ARB was working again.
What it boils down too is:
1.Both ARB and detroits are strong.
2.They both put more pressure on the axles, detroit more so since it locks even when you don't want it to.
3.The ARB does have more things to foul up (but if properly maintianed, your safe).
4. The Detroit is unlikely to fail, but you lose the option of an open diff which is crucial in some situations.

AND...I've never heard of someone with the ARB that wishes they had a detroit, and I have heard folks that wish they had an ARB instead of a Detroit. I guess some folks with the detroit will never know what they are missing with the versatility of the ARB. I would venture to say that if there was NO price difference, many more would be running ARB? Just a few thoughts.

"I've never heard of someone with the ARB that wishes they had a detroit, and I have heard folks that wish they had an ARB instead of a Detroit"

Well Kyle owns both and said likes the truck w/ the detroit the best. I still haven't made up my mind about what is going to go into the back of mine but that fact alone makes me lean a little more towards the detroit...... Plus I've owned a detroit in the past, never had a problem and therefore am not really sure how much of an improvement an ARB could really be.

RJ:
I bought my truck for a very specific purpose, access to my hunting camp during all conditions I might expect to encounter in Michigan's UP. In selecting the truck I ended up with, I first owned several other trucks, and when replacing the last one, looked high and wide for the Disco I ended up with. As the truck has continuously granted me access to a piece of property that at times of the year was inaccessible to me in lesser vehicles, it meets the requirements I set for it. If I do not NEED a locker to gain access to the place I bought the truck to get me to, that seems pretty damned objective. I didn't just by my truck to play with, I bought it to get me somewhere lesser vehicles were unable to get me to. The fact I can go other places is added value.

I still see no reason for ME to have a locker. Winch, yes (I've been stuck at the camp for days, digging other vehicles out), but locker no. Funny thing that need versus want.

Oh yeah, I haven't broken anything off-road yet. A light foot and open diffs are certainly contributing factors to the longevity of my trucks and their component parts. I drove each of my Chevrolet trucks many miles (pickup 98,000 before breaking the crankshaft, and the Blazer, 198K), but both of them broke many parts while trying to get into and out of the camp, including bending the frame badly on the Blazer and destroying major suspension parts on the pick-up.

Peace,
Paul

The fact that I WILL lose on-road performance with a Detroit is about all the convincing I need to go ARB. I travel big distances on road before I really need off-road performance.

The fact that Detroit has delivered failed units that require installation to determine they are bad is not good (this counts in the reliability of the overall part, if it setup too loose like Kyle implies, it has failed).

Will: I believe that the Detroit has a mechanism that disengages the locker when wheel speed between the two wheels is different. Conversely the wheels must be going the same speed to engage. I would assume that there is some slippage in this process and also the problem that in different situations it might engage and dis-engage repeatedly. However, I am not an expert, just talking it through.

PS: got any pix of that rear QT diff guard and how it attached?

That's what I mean Paul...In my old age (be 29 soon heh heh) I've seen lots of things come and go on my truck and I realize there's a fine line between "want" and "need"...and I "Need" a locker LOL. But for What I do with my truck, I, at times find myself sitting there muttering about that wheel in the air, spinning furiously.

From your description a locker would probably dig you deeper. But I'm warped and my sick sick psyche cannot find a "ceiling to this madness." to quote Rush Hambleton.

Literally, we've made need subjective. LOL

Where is all this stuff coming from? How do you lose on-road performance with a Detroit? I've been pleased as hell with mine, and can't even tell its back there. On-road, off-road, dry, rain, etc., the truck feels the same all the time.

Who mentioned Tractech delivering faulty units? I must have missed that. I'd never heard that before you metoned it. Any manufacturer can deliver a faulty unit now and then, but in 4 years of reading about lockers for Rovers, Jeeps, and other 4x4s, I think I can recall ONE instance of someone getting a bad locker from ANYONE. It's so rare as to be considered insignificant.

There is no slippage in a Detroit. It is either locked or unlocked. It will not lock and or unlock repeatedly.

Again, I have nothing against the ARB unit. In personal experiences (though I've not owned one) I have known only a single owner who's never had any trouble with his unit. Every other person I know personally who owns ARB units has had a failure of one type or another. I do not personally know anyone who has had a Detroit fail. This doesn't mean they don't, and it doesn't mean all ARB's are unreliable. But from my personal experiences only the ARBs are about 1 for 15 and the Detroit's are about 8/8. Perhaps other people have different experiences.

By the way Brian, I normally commute about 30-80 miles a day in my Detroit equipped truck in both city and highway driving and I would not hesitate to recommend one to anyone.

You guys yappin' about your open diffs and your "needs" are cracking me up.

All it takes is one obstacle on 1 trail. .. Not a bunch of wear and tear over the course of years and numerous trails... Just one obstacle on 1 trail and all your stock open differentials would become diff salad.

I think like this:

on a scale of 1 to 100, ARB and Detroit might fight it out in the 97 to 99 range so knock yourselves out argueing over the minutia. A Truetrac will score perhaps an 85. Your stock open diffs? LOL, Maybe 15. It really is THAT bad.

Dickens first. The bad out of the box units is kind of a strange arena to get into. You and I could have the same locker that is setup wrong and I would notice it and you never would. I feel tht most dont. I hear every now and again that someone has one dragging a tire or banging back there and I know exactly what the deal is. Some would say its "Broken" some wouldnt. Fact is , it would still do what it was put in there to do. The same cant be said for the ARB failures. When its fails on you , it stops doing what you bought it for. You might get a clunky detroit and decide not to send it back and get it replaced. it will indeed be clunky but it will still get the job done.
As far as how many are clunky ? Well , I have had one out of the many that I have installed . Thats a pretty good ratio...
Perrone ? These are the units I am talking about that make the truck drive funny. Its harder to unlock them therefore you notice it in turns and such.

Oh , and Dickens , your statement about the detroit locking and unlocking is right and wrong at the same time. If there is alot of power applied to the rear wheels then that bitch is staying locked and thats that. When it unlocks is greatly dictated by how it was setup from the factory (Preload). When you watch the videos from the site (If you bought any) , watch and see if you see wheels dragging or any binding going on. Alot of the trucks have a rear detroit.

Peter: Blue, are you saying the idea of the spool not unlocking under load never occured to you? Ever notice that the little six-legged light on the dash doesn't go off until you hit the top of the hill?

i wish my head was made outta plywood.... it seems to be just as dumb, but not as stout mechanically. one particular thing that beats me is that you know all the fucking answers and keep the fan spinning. and i bet if you didn't get your Disco with the ARB installed already, you'd have a nice'n'simple'n'cheap Detroit in it.


I was trying to get some REAL info out here on the board so that all the lurkers have some REAL info to read, rather than the same old "ARB sucks, Detroit rules" -or- "ARB rules, Detroit sucks". Kyle was just the guy to answer because 1) he knows what he's talkin about, and 2) he runs both systems. Yes I understand the concepts, but does everybody else? They do now...

For the record, my ARB has always been very good about unlocking after I hit the magic button. On a few occasions, namely climbing and turning after an obstacle like Kyle brought up, the unit is still obviously locked for a few feet of forward travel. The curse of the spool. I can feel the old girl's spindly legs groaning under the strain, but at least it's gravel under her shoes that offers a little give.

Also for the record, I have done ABSOLUTELY NOTHING to maintain my vastly complex, high maintenance, magic ARB system, other than simple visual inspection. Once the magic button didn't do it's thing because a wire had come loose behind the compressor switch. This didn't let me down on the trail, because I test the ARB in the garage before I head to the trail (this is what you do if your head is not made of plywood).

I just took a break from typing and went out to the Disco and pushed my thumbnail into the shrader fill valve at the end of the airline I have connected to my ARB. Woooooooosh. That shitty little ARB system has been holding it's pressure since Saturday. The compressor is in the back of the truck, it has been under water, and it the Disco operates in 110+ desert temps. And you know I ain't easy on it :-)

And no, if I had bought an open diffed Disco, there wouldn't be a Detroit in there now. One of the reasons I chose this used 96 over a used 97 (which was in better condition and that killer olive drab color I wanted) is the fact that this white 96 already had the locking rear. I'm still not sold on the Detroit's benefits over the ARB.

Perrone,

Loss of performance on road was said by Kyle in this thread and I have heard this before.

"The ARB truck certainly drives better on the road then the detroited Disco"

Also Kyle made the comment on reliability and this could relate to the ratcheting, clunking that I have also heard here and other places.

"In short , they are all not the same and some come out of the box fucked up."

I am not knocking detroit, just trying to come to my own conclusion about what I have heard and what I have read on discoweb. Are there any unbiased 3rd party comparisons of ARB, Detroit...? I would be interesting in reading them if someone knows about them.

How does a Detroit lock and unlock. I thought that it was the difference in speed that unlocks it. So what does this mean when you are on a road with curves and the wheels go from different speeds to same speed and back. Does it only engage when you are in CDL (think I maybe read this in the other detroit thread).

Conversly with CDL engaged on a trail and you need to turn, will the detroit unlock?

I think that the best way for me to make an educated decision is to be with some people that are running detroits and possibly drive one. Also, my personal experience with running trails with ARB equipped rigs is that I have yet to see anyone even have to fiddle with the ARB.

Perrone, your recommendation goes a long ways considering how much you drive.

mine was tight and i could feel it in certain situations. the truck wanted the ass to kick out on frozen paved roads.

it would bang occassionally and NEVER clicked. once i learned how and when it would bang and i could feel it comming, i new i had to drive in a straight line as long as possible until the feeling went away. this would happen usually when i would be weaving around in a parking lot looking for a spot.

i had once situation where i was on a muddy side slop and the ass began to crab on me, i only had about a foot before the truck would have rolled. i ended up having to steer the front weels down the hill and pepper the gas and i made it crab up the hill slightly (by essentially anchoring the front tire, because of the severity of the turn) after i got the ass back in line i straighten the wheel and gave it all kind of gas and break and eased off the fucker until i got the truck into this wooded area 3ft away. then i had plenty of tracktion and plowed over trees and such rather than gettting close to that hill again.

one time in the snow going up a hill the thing crabbed on me too. other than those two situations the offroad crab never was too bad.

having driven the Range Rover all winter in the snowiest winter of my life i had none of the effects the detroit disco had. but i am starting to think it had more to do with the compound in the futura tires freezing and becomeing hard vs my GY wrangler AT's which where pretty doughy all winter. keep in mind it did not get over 32 deg for almopst 2 month here, and the average low was like 10 deg.

i have heard if you blow out an Axle it will destroy the detroit. and with ARB you will not. i'm not sure why this is so, i'd like to hear some discussion on that.

Why not Ho? Isn't the turning problem and breakage even more of a problem with a locked front? Or is it when you need power up front, you typically need a real locker.

Or is it that I am missing something?

Funny, my truck is nearing 200K miles (turned 166K on the way to work this morning-I'll be near 170K May 1) on stock diffs, stock axles, stock original wheel bearings, even stock original CV joints. I dunno, maybe I pick lines carefully, or maybe, I don't abuse my truck!

Don't get me wrong, I have had far too many pilot-error induced failures, like my blowed up top end, but the diffs and axles seem adequate for my NEEDS.

The only person I know other than Perrone who has blown up a stock differential probably would have done more damage had he been locked. Spinning wheels that suddenly gain traction will break parts regardless of whether it was a stock diff or a high-dollar locker. Had the individual I knew who blew up his diff had a locker, he might well have been looking at replacing axles as well as the carrier. The only time I've blown up a locking ( OK, it was an LSD) diff was in a dual-carbureted Nova and I did not set the pinion pre-load correctly and took eight teeth off the ring gear after missing a shift-adding insult to injury, I broke out too!

I am certain that the vast majority of Disco owners have open diffs and find the open diff to be satisfactory to their needs. I have no plans for a locker in the Series either.

Now driveshafts are another story entirely, they don't seem adequate for mall crawling!

Peace,
Paul

Correction - Had the individual had a locker, he wouldn't have blown his diff.

Paul,

I broke my rear diff without any spinning what so ever. Torqued it to death and snapped the pin. It made a pop and sounded just like a axle breaking. My front was a different story, I broke that because I came down on a rock with my tires turned and spinning crazily. I smothed out the spider gears.

Now when we start talking about exclusively the front end we get into a whole other area...

By the way , the Detroited Disco is makiing a 140 mile round trip commute each day now. I was driving the ARB locked truck and then switched off. Not much difference.... I think you would notice more of a difference in something not lifted as much as these two as the truck would drive better to start with..

Paul,

I didn't blow up a diff. I burned it up. Damn shady gasket kept dripping and I didn't fill it up before hitting the highway. Nothing strange there other than severe lack of lubrication and that would have fried ANYTHING. I am incredibly gentle on my truck while off-road and my stock 10 spine axles have served me VERY well.

Rob, I recalled that hairy situation you discussed earlier, and that's why I asked (figured I'd let you bring it up if you wanted). Now, in my opinion, that's just as unacceptable as hitting the magic button and getting nothing. It's there as a traction aid, not a traction hindrance. If the ARB fails (which I have to assume it will, eventually), then you're back to basics...open diff. If the Detroit starts acting up on you, you're potentially fucked. Just as worthy of the garbage as a failed ARB in my opinion. Maybe the Detroit needs a magic button to turn it OFF, not on.

hey guys -

from what i have seen, the arb is stronger than a detroit. i base this on the fact the the detroit uses shallow but multiple engagement teeth, whilst the arb engages with an entire gear set. simply put there is more mass locking the diff when used.

the detroits make noise on the street, some people are ok with it some are not.

if an axle blows in a vehicle with a detroit - you loose the detroit. you have about 2.5 axle breakages with an arb.

to me the arb is the better unit as it is more sophisticated and has greater flexability.

my feeling is the arb vs. detroit is somewhat like the m16 vs. ak47. one is more sophisticated more accurate, the other a crude but reliable one.

my feeling is that most arb failures are due to improper installation and or line routing. with the advent of the 'hdal' heavy duty air line, most of the blue plastic line breakages are at thing of the past.

this is not unlike people who cobble together ar15s from bargin basement sources and then cuss when their frankenguns don't cycle at the range.

will - re: your failed compressor- you do know their require maintenance? there is an arb 'survival' kit that will fix 99% of failures.

i am putting my money where my mouth is and am getting a arb for the tail of my rig and a arb compressor. i had one on my xj for years (as well as a front locker), and have used them repeatedly on the trail with no problems and it has also aired up my tires just fine (granted they are just 235-85's).

Blue, you must've forgotten, I had a locker in the rear, so I have some idea of what it is, how it works, and what the pitfalls are. I drove the truck to work every day, and off-roaded it heavily. The locker I had in it was supposedly inferior to the detroit, however, it never broke and took me 70 miles back home on a single axleshaft. I never had to adjust my driving because of it, and it was fun to watch the starbucks crowd at the tight corner I had to pass often, jumping at the bangs coming from my truck.

now three of my trucks have limited slips in the rear - the disco will get the front one, and stay that way as long as I am not its primary driver. I installed two of those, as well as the locker i mentioned before - so I've had a chance to see what's involved with one or another diff. You've got lucky with a clean install of an ARB and are now bragging about it being the second best thing after sliced bread and whining about not hearing any significant arguments. Now, your claim about educating the others by means of asking the same question over and over sounds very much like "teaching the newbies" from old thread.

Being the 'more sophisticated' and expensive setup, I'd think this argument should have the ARB justifying why IT is the better diff. So Blue, maybe the argument should be: What makes the ARB so much better than the Detroit?

Just a thought. :-)

will -

never said you were dumb! - you've got alot of rovers and nice ones too. my apologies for any inferences to that effect. i've had and used the arb compressors before with never a glich.

the 'survival kit' was shown to me by my western region manager for arb during an air locker explanation session during tierra del sol.

if you email me - i'll send you full details.

"People think they are too tight when in reality they are setup too loose. This will make them drag tires and bang and carry on. I had one and sent it back and got another that was just fine. SO its really nothing to do with the install but rather the assembly of the diff itself. Its not technically broken , just not setup optimally."

That's EXACTLY what goes on with my detroit. Worst in parking lots. Sounds like a 12 gauge sometimes, people duck.

Question. Am I chewing things up back there when this happens? Yes, I'm too lazy to drain the rear diff and check for teeth! I've had it for a couple of years, it bangs around occasionally, but seems to work fine on the trails. Should I preemptively replace it because it's "dragging and binding and banging"? I should have sent it back when it was under warranty, it sounds like. Should I be carrying my stock diff with me on the trails? My parts box gets bigger and bigger!

And yes, you do have to learn to modify your driving style with a detroit sometimes. You can't just turn it off on a snowy sideslope, for example. For me, I'd rather be forced to drive a bit smarter and be able to keep the KISS rule in full effect. Hence the Detroit.

Settle down Kyle,

"somooth" was refering to the on road issues. "semi-effective" was refering to the off road.

Damn, Do I have to go all John Lee on you here and define, redefine and cross reference every word?

There's no Electrac for Rover axles. I doubt there will be one soon as it engages using a shift fork mechanism actuated from the "diff cover" side. Hence no such thing for third-member style axles. For Salisbury axles on the other hand, who knows? Maybe they'll have one one day.

Brian,

i suggest the detroit for the desert because there is no snow and there are no muddy root strewn trails out
there where the detroit will crab. out there it's all high traction rock, perfect for the detroit. out here in the perimeter there are no stars Out here we is stoned Immaculate.

There's no Electrac for Rover axles.

For some reason, the electrac doesn't sound like the best option for a rear locker in a Rover. I'm not sure why...I can't quite put my finger on it...hmmmm....
