Umm... That's a load of crap. Ever cracked a detroit open? Do you have ANY clue whats in there???

Detroits make noise. I've owned 6 of them in axles ranging from Dana 30, 44, 60, and 9"s. They ALL clunk and pop every now and again. They are ultra simple, with a pair of side gears, a pair of springs, a pair of clutchs and a spider gear assembly. That's it. There's no adjustment possible, other than perhaps replacing a worn out spring.

The REASON that they make noise is that their resting position is locked. Especially in low speed, high traction manuevers, ie... parking lots and u turns, the locker must disengage and the outer tire must turn much faster than the inner. That's the rachetting you hear during the manuever. After your turn, if you get a pop, its because the locker relocked before the axle shafts were 100% in phase. It pops out, then relocks.

The performance you are noting is 100% normal.

Why would having a 5spd over an automatic make a difference? I have a manual transmission so I'm curious about this.

My Detroit made some pretty violent clunks when it first went in, but over a couple months of driving it smoothed out some. Now (using the term loosely since my truck is completely #*&^%#'d) it probably does something once every couple weeks like others have mentioned. In general the noises don't seem as bad as they used to be either, but since it's expected behaviour I don't worry about it.

Sethmark please shutup... Thanks...
Do you have a soft locker in your Rover ? How many have you installed ? Have I had one apart ? Yep... Have I had one in a 9 ? Yep , still got it , the old style , and yes it drags a tire now and then and yes it makes some noise .

This is where shit gets all clouded most of the time here. A dude asks a question , he gets an accurate answer and then some other dipshit bails in talking about Dana this and 9s that. Its a fucking Rover with a soft locker.. Tell us about how many of them you have ... I probably have more locked shit sitting in the driveway right now then you have owned throughout your whole damn life..... Now the 24 post wonder is here posting about something that has been covered about half a million times before he knew the site even existed.... If you dont have any more knowledge about it then talking Danas and 9s then just shutup..... Easy right ? Thanks......

They are quirky with stick because of the driveshaft input going through a turn. A stick can jerk slightly like with a high gear selection at a low speed and that freaks the detroit right out... However , the detroit in my 9N ford tractor doesnt seem to mind to that must be bullshit... (Yes I was making fun of the above)

Boy, aren't you a pleasant guy? But even with your bile and vitrile, there's still no truth to your comments.

I encourage you to read:

Seth (and as for my experience, it ain't based on sitting in front of a computer convincing the world that I'm an expert. Its from getting my hands and vehicles dirty. Post count doesn't tell you ANYTHING about that, now does it? )

Hmm, interesting. I forgot to mention in my previous post that my Detroit is in my front axle. Would this make a difference with a 5spd? (j/k).

On the one hand I haven't spend much time behind the wheel of an automatic with a Detroit for comparison, but the setup seems to work fine for me. As long as the differential "freaking out" doesn't involve me losing control on- or off-road, I can deal with some strange noises and stuff. So how serious and theoretical vs. usual are these different behaviours with a manual? I know what you mean about the driveline looseness in a higher gear, but haven't really come across anything like that due to my locker. Are you basically saying that without the torque "converter" (I always figured that was newspeak for "dissipator") in the way, in a turn the manual transmission can apply torque more directly to the wheels which can cause one of them to spin slightly in a turn?

In a nut shell Andrew the auto has somewhat of a cushion between the engine and the pinion at the rear. With this , you dont get that harsh changes in input that you get with a stick on and off the gas or in the wrong gear... Almost everyone with a stick complains about noise.. Its not a problem , its just noisey.... With the Auto , if its a good locker you wont hear anything outside of a faint click. Now from time to time you will get a bang or if you drive aggessively but outside of that you really dont know its there.....

However , dude says I should read something and that will change the universe and the way things are....

Kyle,
I'm glad that you're experienced. If you would like a copy of my resume, I'll be happy to PM it to you. You might find that you're not the only person out there that's breathed the air.

Meanwhile, clunks while doing u-turns with detroits is normal. Especially if the driver is on and off the gas.

Don't need them in my Rover. The hard core trails I run a Rover doesn't fit on anyhow. Got a pair of them in my trail rig, though. And the last one, and the one before that.

So, explain to me what's different about the Rover detroit and how it can be adjusted. I'm just itching to learn something new tonite.

I hate to step in here but are you trying to say that the detroit in a rover is made different than other detroits. Seems as though they would behave in a similar manner no matter what carrier they are sized to fit.
And no, I do not have them I have ARB's. Just trying to clarify what you are saying.

Looked to me like a detroit is a lockrite inside its own carrier.


Flame on!!

So you dont own one nor have you any experience with one. But you are telling me how they are. Call Trac tech and ask them how they are built... You aint going in there and turning a screw to adjust it... If that was the case I would be telling dude to adjust it... However , I am telling the guy that when it was setup at the factory it was setup too tight and it doesnt want to unlock as it should. Therefore you get the bang when it finally gets enough input to force it to unlock...

And no John they wont behave the same because they arent running a center diff and have the whole "Full time" thing going on. Notice that dude is saying he is runnign a pair of them ?

Hard core ? Lets see some hard core action.....

Hmm, interesting comments on the Detroit/5spd combo. Well I'm not complaining about how mine sounds or works. I expected clicks and clunks, so who cares as long as it works. Of course, I wish I had an ENGINE that works, but hey we can't have everything can we...

I'll play your game if you play mine. HOW can it be setup differently, if the tension of the locker is set by the 2 springs?

Hardcore? From where around the US???? Oh, and you'll have to tolerate Jeep pics, as I just acquired my first Rover. Pick a trail system.

Dusi Irshim... :D And why would I have to "Tollerate" jeep pics ? Its got 4 wheels right ? If its a beater I will give you some shit but ouside of that who cares.....

And I am telling you what I was told by Trac Tech after I installed my second bad one..... If thats not good enough then I really dont know what else to tell you.... 99.9 % of the ones I install in a rover are silent aside from the ratcheting........
