[Fot] Diff setup

[Phil Gott]

Greg;
This could work if you get the preload correct. I would think it would be hard to install the carrier into the housing without damaging the shims. Damaged shins might feel good and give you correct pattern, but could creep out of place over a few miles.
Yes, removing the bearings (‘cones”) each time is a pain and risks ruining them each time. Someone on FOT suggested grinding out the ID of the cones of a couple of old bearings so they can be removed easily. That would get you close to the right set up without screwing up the new bearings. With s little luck your last installation with the new bearing cones would be right-on ( correct backlash, preload and pattern).
Good luck! I’ve done this so many times with mixed results that I now send my diffs out to Quantum Mechanics to do it for me.
