Anytime a differential pinion shaft locking screw is removed (Figure 1), it is important to coat the screw threads with Loctite 242 before reinstalling. These screws are coated with an adhesive which helps to prevent the screw from loosening in the case. When this screw is removed, the adhesive is also removed. If a new locking screw is necessary, they are available through GMSPO and are coated with the correct adhesive.

Torque the locking screw to 36 N-m (27 lbs.ft.)

PARTS INFORMATION:

If a new differential pinion shaft locking screw is required, order 14056196 and Goodwrench 242 Threadlocker 12345382.
