This repair was performed on a 1981 Corvette, compliments of Jacques.  Thanks !  It will take you at least an hour to change out the old bushing; it's not easy but it is do-able.  A long pry bar is a must and on some cars the brake line may be in the way.  A friend can be a real help while prying.  Don't put your fingers anywhere that you could get them pinched.  I used a "poly" bushing, instead of rubber.   On the 1980 - 1981 and 1982 there were only three mounts on the differential: one on the lower front and two on the top sides.  The lower front one is the subject of this article.

Tools needed

026

Parts required:  Corvette Differential Pinion Mount Kit

019

Jack up the rear of the vehicle as high as possible.  Secure vehicle with jack stands. Locate the bolt and nut.

020

Remove the nut while holding the bolt on the top. (Note the wrench on the top)

021

On some cars you don't need to remove the drive shaft to remove the bolt. Push the bolt up a few inches.

022

Pry down on the diff and remove the lower half of the mount.

023

Rotate drive shaft to make room to remove bolt. (See head of bolt).  Bolt should come out on the passenger side of the shaft.

024

Remove upper half of the mount.  It comes out on top, toward the front of the vehicle towards the drive shaft.

027 

Separate top flat washer from the rubber and use a flat washer on the new one (if the flat washer is in good condition)
