Tools Required

Notice: Do not use excessive amounts of sealer. Excess sealer could plug the vent passage, the oil pump, and/or the oil pump screen causing internal damage.

Important: 

•	Ensure that the sealing surface is still clean and oil free.

•	DO NOT apply sealer to the vent walls (2).

1. Apply sealer GM P/N United States 12346240, GM P/N Canada 10953493 to the rear housing sealing surface (1). Apply a constant bead of sealer 2.5 mm (0.098 in) wide and thick.



2. Install the dial indicator on the cover at the top of the bearing bore. Preload indicator and zero it out.
3. Install the J 44868 on the cover.

Important: DO NOT spread the cover more than 0.30-0.40 mm (0.012-0.016 in).

4. Spread the cover while measuring the movement.
5. After the spread is reached remove the dial indicator.



6. Install the cover.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

18. Apply sealant GM P/N United States 12346240, GM P/N Canada 10953493 to the sealing surface of the differential housing. Apply a constant bead of sealer 2.5 mm (0.098 in) wide and thick.




Important: 

•	Rotate the input flange in order to properly align the splines of the clutch drum hydraulic pump and the pinion shaft.

•	Allow the RTV sealer to cure for 12 hours before oil fill.

19. Install the clutch cover (2) and bolts (1) to the differential housing.

Tighten
Tighten the clutch cover bolts to 26 N·m (19 lb ft).




20. Install the dust deflector (2) to the flange (1), if required.



21. Install the flange (2) and a NEW nut (1) to the pinion shaft.

Tighten
Tighten the flange nut to 203 N·m (150 lb ft).




22. Using the J 44809 , install the left axle shaft oil seal (1) into the differential housing.



23. Using the J 44809 , install the right axle shaft oil seal (1) into the differential housing.



24. Install the rear mounting bracket (2), bolts (3) and nuts (1) to the differential housing.
