Torque # for the Differential Cover Bolts

[Bob Chadwick]

The heading says it all. I can't find it in the AIM, I guess because it's put in as a unit.

Thanks D.

Nope - 20 ft-lbs. is for the small bolts that hold the sheet metal diff cover on a solid passenger car axle. The Corvette diff cover is a major structural casting (that holds the rear spring in place), and has 7/16"-14 (5/8" hex) bolts - they're 50-60 ft-lbs.

Re: Thanks to JohnZ

I stand corrected & now can update the Chassis Restoration Guide which is blank.

Another missing torque value is the trailing arm to spindle support bolts (3/8 - 24 - 2 7/8). John, can you provide?

Thanks,

30 ft-lbs.
