8.25" Rear Axle Rebuild Part#s
I have been lurking around here, but I just finished replacing all the rear differential bearings in my 08 GC 3.7 with quadratec 1 and I had some problem chasing down all the correct part numbers so I thought I would pass it along here.
All the bearings in the stock rear axle were Timkens, so that is what I replaced them with. The pinion bearings on mine were shot and making a bunch of noise, which is why I replaced them.
Carrier bearings - Timken SET 36
Pinion rear outer race - M86610 Timken
Pinion rear inner race - M802011 Timken
Pinion rear outer bearing - M86649 Timken
Pinion rear inner bearing - M802048 Timken
Pinion seal - 710480 Timken
Pinion Crush Sleve - 3507575 (Dealer sourced)
Pinion nut hex head size = 1 1/4"
