Rear end question

OK Jeff, here you go.

Pinion bearing Preload is 12 - 15 in lb with new bearings. If the bearings are used then aim for 6 - 8 in lb. Don't forget, if you overtighten the pinion yoke nut & end up with too much preload you have to change out the crush ring. The secret is to sneak up very slowly on the desired preload by tightening the pinion nut a small, & I mean small (maybe 1/4 of a flat) amount at a time.
Once the diff carrier with ring gear is back in, set your backlash at 0.006 - 0.010 using a dial indicator attached to a magnetic base. Check backlash in 3 different positions.
Then mark up 5 or 6 ring gear teeth on both sides with marking compound & check the gear contact pattern.
Hope it helped.
Cheers. Gaz
