Special Tools

1. Raise and support vehicle. Refer to Lifting and Jacking the Vehicle .




Important: Remove only the propeller shaft coupler-to-differential flange bolts. Do NOT remove the coupler from the propeller shaft.

2. Remove the propeller shaft coupler-to-differential flange bolts (6), nuts (4) and washers (5).
3. Push the rear propeller shaft (1) toward the front of the vehicle in order to release the propeller shaft coupler (2) from the differential pinion flange (3).
4. Carefully position the propeller shaft (1) out of the way and support the propeller shaft using a suitable jack.



5. Install the J 45012 to the flange.
6. While holding the J 45012 , remove the drive pinion nut, using J 34826 .
7. Remove the J 45012 .



8. Using 303-642 (1), remove the drive pinion flange (2).

Important:  Take care not to damage any sealing surfaces.

9. Using a flat-bladed tool, remove the drive pinion seal.

1. Lubricate the drive pinion flange sealing surface of the drive pinion seal with GL75W90 synthetic axle lubricant SGM P/N 89021677 or equivalent.
2. Install the drive pinion seal to the J 45005 .



3. Using the J 45005 , install the pinion seal to the differential.
4. Remove the J 45005 .
5. Remove the 303-642 .



6. Install the J 45012 .
7. Install the pinion flange to the drive pinion shaft.

Important: The drive pinion shaft threads and the drive pinion flange nut must be free of residue and debris prior to application of threadlocker in order to ensure proper adhesion and fastener retention.

8. Prepare the pinion shaft threads and the pinion flange nut for assembly:

8.1.	Thoroughly clean the residue from the pinion shaft threads by using denatured alcohol or equivalent and allow to dry.

8.2.	Thoroughly clean the residue from the pinion flange nut by using denatured alcohol or equivalent and allow to dry.

9. Apply threadlocker SGM P/N 12345382, 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 in the Preface section.

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
Tighten the pinion flange nut to 245 ± 15 N·m (181 ± 11 lb ft).

12. Remove the J 45012 .



13. Install the propeller shaft coupler (2) to the differential flange (3).
14. Remove the jack.
15. Inspect the propeller shaft-to-flange nuts (4), bolts (6) and washers (5). 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.

16. Thoroughly clean the threads using denatured alcohol or equivalent and all to dry. Apply threadlock SGM P/N 89021297, 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 fastener. Allow the threadlocker to cure approximately 10 minutes before installation.
17. Install the propeller shaft coupler-to-differential flange bolts (6) and washers (5) to the propeller shaft coupler (2) and differential flange (3).
18. Install the propeller shaft coupler-to-differential flange nuts (4).

Tighten
Tighten the propeller shaft coupler-to-differential flange bolts to 85 N·m (63 lb ft).

19. Inspect the fluid level. Refer to Rear Axle Lubricant Level Inspection .
20. Lower the vehicle.
