Here is a link to the post from way back from Armybuck about rebuilding Mutt differentials.

Hey Rick, thanks for posting this!! I am about to start on 2 of my spares to put in the Alley Cat.

Unfortunately it does not show setting up the pinion depth. I will have to add that in using one I just took apart.

In Armybucks thread he shows a rebuild but does not disassemble the carrier so I wanted to show a few pics of the entire unit disassembled. This has got to be one of the simplest differentials I have ever worked on. Lets see how many of you see the problem with this diff.

Fun !!

This is going to be good....keep us posted ....

This is just an addendum, the original post is stickied up top. There is really nothing much to do to set pinion depth in these, there is one shim and I haven't seen any other options for changing that.

Rick, looks like a couple bearings and races could help. Especially if they were submerged in water for a long time.

I bought a new one from blake 3 or 4 years ago and it was worse than the one I took out...I heard red river was no longer in business is that true??

[rickf]

Red River is very much in business. They sell on E-bay

Looks like the yoke area is banged up, no, in other pics it looks ok

[rickf]

Nobody saw it, This diff came out of the crushed mutt I have. When they crushed it they really crushed it!
Look at the mounting ear on the right. Click on the pic for a better view.
