Started the install of the 4.10's. Everything is out. I still need to replace the bearings on the diff, and then begin reassembly. Chipping away at thinks a couple of hours at a time when I can.
I'm using a spare pinion bearing with the center bored slightly that I can easily slide on and off to get the shim correct. Then I'll press on the permanent one. I measured the spare bearing and permanent bearing and the bearing+race depth is within .001", so I'm not concerned about shimming for one but using another.
3.55 left. 4.10 right.
