Does anyone have a write-up on how to rebuild the diff? My orignal made so much noise I had to replace it and now the old one is just sitting around. I want to have a go at rebuilding it but I can't find anything specific to the E21. I know, I know, special tools, difficult to do, etc, but I've never let it stop me before. If I screw it up, well, I have a working diff anyway and I can take it somewhere to get it done.

Okay, does anyone at least know what the torque friction should be on the new bearings that I'm going to put in?
