2. Apply a small amount of lubricant GM P/N 1051344 (Canadian P/N 993037), or equivalent, to the front and rear propeller shaft centering
bushings.
3. Inspect the propeller shaft to flange nuts (4), bolts (6) and washers (5). Replace if damaged or worn.

10953488), or equivalent, to the propeller shaft to the flange bolt. Ensure that there are no gaps in the threadlocker along the length of the filled
area of the bolt. Allow the threadlocker to cure approximately 10 minutes before installation.
Important: If reusing the propeller shaft-to-flange nuts and bolts, to ensure proper adhesion and fastener retention, the threads must be free of
debris prior to the application of threadlocker.
