Note: Ensure that the coned end of the propeller shaft CV joint is installed into the transfer case flange.
- Install the propeller shaft to the transfer case flange.
- Install the propeller shaft to the differential flange.
- Inspect the propeller shaft-to-flange bolts. Replace if damaged or worn.
Note: If reusing the propeller shaft-to-flange bolts to ensure proper adhesion and fastener retention, the threads must be free of debris prior to the application of threadlocker.
- Thoroughly clean the threads using denatured alcohol or equivalent and allow to dry. Apply threadlocker GM P/N 12345493 (Canadian P/N 10953488), or equivalent to the propeller shaft-to-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.
Caution: Refer to Fastener Caution in the Preface section.
- Install the 6 propeller shaft CV joint-to-differential flange bolts in sequence (1-6) and tighten to
36 N·m (27 lb ft). Ensure that the crescent washers are in place on each pair
of bolts.

- Install the front propeller shaft coupler-to-transfer case flange bolts. Ensure that the crescent washers are in place on each pair of bolts and tighten to
36 N·m (27 lb ft).
Note: Ensure that there is no rotational movement between the CV joint (2) and the propeller shaft tube (1).
- Install the propeller shaft heat shield. Refer to
Shield Replacement.
- Lower the vehicle.
