    Rear Diff Rebuild Question

    I'm starting this thread because I don't want to clutter up Sand and Sea's sticky. That's just too much good info to string it along.

    So I get everything apart. There are 2 large washers, appear to be 37mm ID and 60mm OD. I say apparently because they are slightly concave. I'm gonna assume they got bent when the bearings let go. Would this be a correct assumption? Secondly, do you think this is a part that is specific to the AC diff (IE hardened steel, special steel, etc), or would these be something I can match as regular hardware? And for the record, I've never had snap rings that were so %%##%^&& difficult to get out, nor bearings in so tight!!!!

    TIA, SS.

    Looking at the diagram I would be willing to bet everything inside is special and even if it weren't your putting so much work into this for me it wouldn't be worth it not to order any new pieces from Arctic Cat. My 2 cents, no charge to you!

    Agree with AZ..... All the time and work plus the strain the diff is put under I would go with AC parts. It's a project I would like take on one of these winters.... Hope it goes well sandsissy. Would like to wait until I pull the motor for the rebuild and fix my compression issues. But she is running good and strong for the time being. Keep us posted on the progress.

    Unless these are from the clutch pack (not likely), I'm thinking Ring Gear Shims and not washers at all. Not bent. I sent you a PM.

    Most of the carnage has been tossed. But don't fret....I have another one to do after this one. The insides of Rockster's Diff looked just like the magnet/bolt on yours. Quite a bit of scarring inside, but should be OK. It's pretty cool when you open one of these up and 00 Buck and shrapnel falls out.

    I just changed the rear diff fluid on mine. Fluid was amazingly clear, just a little sludge on the magnet, and some grey dusted oil toward the end of the drain. That made me happy. New starter is in. New steering rack is in. Oil and filter done. Trickle charger on the battery. Just have to adjust the shocks and check clutch alignment. Everything looks ready for Jawbone.

    Just an update. I've spent soooo much time getting the Car and the MH ready for Jawbone next week, I just haven't had time to dig into this thing any more. I'll try and figure everything out when I get back. Besides, I'm sick of smelling that rear end lube.
