The front's are readily available from the gear dude in OZ. I'd be in for tossing some pesos at a whole 3rd if somebody thinks it might work...

Do you mean an indicated or actual 60mph?

I seem to have misplaced my photos of my Raider and the FG140 that occasionally makes my way. The rear axle in it was HUGE, similar to a Dana 130. I could not find any literature on the Mitsu-Fsuo website about ring gear size. The threads above may have some useful info for this thread.

If any part numbers from within the diff are available, get the bearing numbers from the pinion and cross them to the SR. This may get close to answering if the gears will go in.

Can't a physical measurement be taken on the part itself? Or does the deflection angle of a gear teeth vary even within the same ring gear size?

I think I'd go measure the two, count the teeth and check how it bolts up. <img src="/forums/images/graemlins/confused.gif" alt="" />

That would be fine if anyone could get their hands on them but the parts are not in country.

A better chance for 5.29's for the 9.5" diff is bolting a 5.29 9" ring gear to the 9.5" centre.
The two ring gears are exactly the same ID and OD the only difference is the mounting bolts (9.5" are thicker). The reason for the larger housing is to fit the bigger 9.5" bearing assemblies.
I know of a guy who bolted a 9.5" ring gear to a 9" centre with a little bit of work so a 9" 5.29 should fit onto a 9.5" centre with a bit of work.
This may solve the 5.29 rear for the 9.5" diff but the problem still remains for the 8" HP front - there is no option other than having a custom unit made at probably great expense or converting to the 8" Gen 1 LP diff.
Only front 5.29 options are 7.25" HP and 8" LP.
The odds of the Canter front live axle 5.29 fitting a IFS 8" HP assembly are slim to none.
I'm pretty sure the Canter front is low pinion anyway.

That sorta doesn't make sense. How can they be same yet be refered as 9" and 9.5"? I've taken apart both. Unfortunately didn't put them side by side but out of curiosity I did measure OD of bigger one and it it was indeed 9.5" <img src="/forums/images/graemlins/scared.gif" alt="" />

This is from ARB head locker engineer confirming this :-

Hi Frank,

I can see what you are trying to do (I think) but there may be some complications.

Here are some notes that you may or may not have considered:

1 Although the ring gear IDÆs are identical the bolts in the 9.5ö are larger, so you would need to make up sleeves for your 9ö bolts to suit a 9.5ö diff.

2 The bearing ID of the 9.5ö diff is MUCH larger than the 9ö, and so you would probably need to consider machining the bearing journal of the locker.

3 The RD154 has a different seal housing system than our RD46 diff, and it fits underneath the bearing cap. This makes it specific to the 9.5ö bearing size, so you would have to work something out for the 9ö. We might have something else off the shelf that would work (a different seal housing that might suit the 9ö bearing) but I couldnÆt guaranty it.

Yeah I remember this discussion. In you post you said ID and OD are the same that's what got me confused. He only mentions ID or mounting surface of ring gear which is 7.5". Could be quite true.

Here two snaps I have.
Here is my Gen 2 with ARB

and Gen 3 Hybrid LSD. Indeed you can see much larger bearing caps.

Although not in quite the same perspective the mesh part of crown wheel appear to be wider or taller if you will which would account for bigger overall OD (outer diameter)
