1. Thoroughly clean the residue from the pinion shaft threads by using denatured alcohol or equivalent and allow to dry.
2. Thoroughly clean the residue from the pinion flange nut by using denatured alcohol or equivalent and allow to dry.
9. Apply threadlocker GM P/N 12345382 (Canadian P/N 10953489) or equivalent to 2/3 of the threaded length of the pinion shaft threads. Ensure
that there are no gaps in the threadlocker along the length of the filled area of the pinion shaft threads.
10. Allow the threadlocker to cure approximately 10 minutes before installation.
Notice: Refer to Fastener Notice.
11. Install the drive pinion flange nut to the pinion shaft. While holding the J 45012, use J 34826 to tighten the drive pinion nut.
Tighten the pinion flange nut to 245 N.m (181 lb ft).
12. Remove the J 45012.
13. Raise the propeller shaft and the front of the RDM until the propeller shaft is installed to the pinion flange.
14. Install the propeller shaft coupler (2) to the differential flange (5).
15. Remove the support.
16. Inspect the propeller shaft to flange nuts (4), bolts (7), and washers (6). Replace if damaged or worn.
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.
17. 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 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.
18. Install the propeller shaft coupler-to-differential flange washers (4) to the propeller shaft coupler-to-differential flange bolts (3).
19. Install the propeller shaft coupler-to-differential flange bolts and washers to the differential flange and propeller shaft coupler.
20. Install the propeller shaft coupler-to-differential flange nuts.
Tighten the propeller shaft coupler-to-differential flange bolts to 85 N.m (63 lb ft).
21. Install the bolt from the differential case bracket assembly to body.
22. Remove the RDM support.
23. Install driveline tunnel closeout panel.
24. Inspect the fluid level.
25. Lower the vehicle.
