MU Diff Specs - Info Required

[Jimmu]

I am chasing the exact specs of the MU diff.

Mine is a 93 2.8 if that makes any difference.

So far I have that they are a 12bolt GMH rear 10bolt GMH front.

What I need is the number of axle splines & o/d of spline...

Thanks in advance

Jimmy.

The rear is a 12 bolt Isuzu corperate diff 26 spline and 33.5mm..... ARB locker RD44

The front is the isuzu 10 bolt (same as older jackaroo rear) 17 spline and 28.4mm..... ARB locker RD94

Don't know if ya wanted the ARB numbers but I have had these in my truck and they fitted.

I could have sworn I counted 27 splines last night....


Arh, just clicked, I was counting shaft splines. 27 on axle, 26 on diff

HI guys, i know this thread has been dead for a while but i'm looking at a air locker for the front on my mu, a 92 2.8 turbo, ucs55 dw7108889. I see yarno says 17 spline for the axles and arb locker number rd94. Am just wondering if these are still correct for my truck. I counted 17 splines on my spare axles which are out of a 95 mu but just want to check to see that all of the numbers are right.
Thanks very much.

The guys at ARB can tell you straight up which airlocker fits. They quoted me on mine and did not even blink at the mention of the MU.

I would imagine that TJM could tell you also.

Sweet as, there was a second hand one for sale on trade me, the guy recond that he talked to truckbits and they said that my truck would have 27 splines and that if it had 17 then someone has put a old jackaroo diff in it what a load of crap!!!

The locker was in a 27 spline diff and someone paid $950 for it, compressor and everything, so i'll try to get in touch with arb to find out what a new set-up is worth.

Thanks very much jimmy.

How about the 3.1's??

Were there any changes after model upgrade during 95/96 too?

I'd love to get some lockers (not the auto ones)
