I need the correct torque specs for the pinion nut when installing new seal and crush sleeve. Long story goes with this, but won't bore you. Also need the torque spec for the carrier bolts. Thanks for any help.

Knowing what kind of rear end you are working on would really be helpful.

There is no torque spec for the pinion nut. You have to tighten it far enough to crush the sleeve and have about 15 in/lb of rotational torque on the pinion if you are using old bearings, 20-25 on new bearings.

Sorry about that Hava. It's in a 99 Camaro. Stock 10 bolt.
mzoomora Thank you! They are new bearings. Don't know what the bolt's for the carrier are supposed to be torqued to do you? Thanks for the help.

I am pretty sure they use a 7/16" bolt (5/8" socket) which would be 65 ft/lb. The larger bolts use 85 ft/lbs. Lock-tite red helps also.

Yep, that's the correct numbers. Here's a few extra if you need them:

Carrier Cap Bolts
7/16" (5/8" head) 60-65 FT #
1/2" (3/4" head) 80-85 FT #

Other torque specs:

Cover Bolt Ft. Lbs. 20
Pinion Brg. Preload In. Lbs 24-32
Pinion Brg. Preload In. Lbs 8-12 Used
Ring Gear Backlash .005-.009
Ring Gear Bolt to case Ft. Lbs. 90
Side Brg. Caps Ft. Lbs. 60

Thanks you guys!! Got the pinion in tonight and will press on the carrier bearings tomorrow and finish up. Glad I did it myself now I'm not as gunshy doing gear work. This seems to be a good place for tech help glad I found it!
