Will I have to get HD axels to accomodate a rear ARB locker?

By Alex Schubow (Alex) on Tuesday, July 24, 2001 - 02:57 pm: Edit

YES

By Ali on Wednesday, July 25, 2001 - 12:38 pm: Edit

Why? Inquiring minds want to know!

By Ron on Wednesday, July 25, 2001 - 12:41 pm: Edit

Not really

Only if you use it or more aptly use it hard or stupidly (like engaging it while your tires are spinning). PLus if you break an axle it probably wont take out the arb like it would with a detroit which you should have HD shafts.

Simply put, "locking" gives 100% power to one wheel, which places more stress on the axle. You don't NEED to upgrade (pieces parts will work together with stock axle), but you're more likely to bust an axle running locked, so it's a good idea to upgrade.

By Mike R. on Wednesday, July 25, 2001 - 01:03 pm: Edit

An ARB, when engaged, is a spool. There is no slippage between the axles. Each axle will turn at the same speeds. If you're mudding, no problem. But if you're on rock, turning alone introduces stress to the axles. I'd rather be safe than sorry & just get the axles & be done with it.

just an update arb thinks you do that is why they are trialing hd axels now
it is safer to get them also depending on what spline you have if you have 10 or 24 this does make a differance 24 are much better

By Kyle Van Tassel (Kyle) on Wednesday, July 25, 2001 - 03:20 pm: Edit

Yeah , ARB has been fooling with that for about 6 months now. I am glad , that will quill the myth that you dont need them with ARBs.

On the HD axel question I am going to up grade axels in the near future and I am wondering what is the opinon on the East coast rovers VS the Great basins rovers Axels.

thanks for the help

GBRs are made of better steel.

ECRs cost less.

Modifying driving habits with ARB lockers will save your 10 splines! With Detroit or similar I can see upgrading the axles but with ARB it's not necessary. Unless of course you have loads of money then go to town and upgrade everything! I'm still running the original 10 splines with ARB for two years! KNock on wood!

By nadim on Thursday, July 26, 2001 - 10:00 am: Edit

Ali...
is that on the rear?...with what size tires?
I just bought an RD56, and will be transforming my rear axle from 10 splines to 24 splines from a later Disco/D90...I run 32" swampers...should I go for HD?...

By Ho Chung (Ho) on Thursday, July 26, 2001 - 10:10 am: Edit

nadim, just replace them as needed.

and the real question should be...
when and under what conditions do i want to or have to replace those shafts?

By nadim on Thursday, July 26, 2001 - 10:13 am: Edit

on a rocky hill top?...with the high lift?...that IS scary!
ok...will contact the UK buddies to carry some axles with them!

By Leslie on Thursday, July 26, 2001 - 10:36 am: Edit

It is my understanding... (and I'm sure that someone will correct me if it's not the case! )...

About '97 the Disco axles were upgraded at the factory. Pre- '97, upgraded shafts are pretty much a guaranteed need. After '97, it'd still be a good idea if you do a lot of mud boggin' at high RPMs, or severe conditions, etc., but that the post '97 shafts are more capable of handling moderated use.

Now, edumacte me if that's not the case, guys....

nadim let me know how you go with upgrade 24 spline wont just slide in as i understand different flange is one thing also i believe they are thicker axel and of course diff center

By nadim on Thursday, July 26, 2001 - 11:18 am: Edit

Kev...
Will have a specific writeup in a couple of weeks

Yup you need to swap hubs and diff of course.

Leslie I thought the change was 95 to 96 and BTW they are still not much stronger. Not like I care as I can change a half shaft in my sleep as I am sure all series owners can.

By Leslie on Friday, July 27, 2001 - 03:49 am: Edit

Was the change concurrent with the OBD-II arrival? I was thinking that it was after... Hmmm.... I'll see if I can dig out any documentation somewhere.. (actually, you've got the better resource at hand to ask at the moment, since she can look it up... oh, Alyssa.... )

Regardless, I agree, they're still "factory".
And yes, Series folk have a nasty nack of changing half-shafts, don't we? ;)

Guys

The 1" 10 splines use the ARB RD03...the 1.25" 24 splines use the ARB RD56, which I got...so the diff issue is taken care of...

As for the difference in thickness, I think my Axle case will not need to be reamed out...but if it does, then I'll simply go to the scrap yard and get me a whole new rear 24 spline axles assembly, refurbish it, and slap in the ARB...

I will know everything in 10 days!
I really cannot wait!

Yup, the 10 splines are on the rear of my RR. We all have a different way of looking at things when it comes to this topic. I guess I'll upgrade to the beefier axles when I start breaking axles due to mechanical issues. If it's my driving habits... that I have control over. Also, I always carry extra set of rear axles when I go out of town for off-roading. An used set of axles cost me $50. I'd prefer a weak link like the axles rather than other parts like R&P teeth, Tcase output gear, busted driveshaft flying everywhere, etc.. Of course it was the money issue too....this shits just gets more and more expensive!

Just my opinion.

By nadim on Sunday, July 29, 2001 - 12:37 pm: Edit

Ali...great for you!...touch wood!
But you did not mention what size tires you are on?...maybe that is the issue...I am currently on 32" and will be going bigger very very soon hopefully...so my 10 splines will be a very very bad idea i think...
