Tools Required

J 8614-01 Companion Flange Holder

1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
2. Remove the rear wheels. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
3. Remove the drums, if equipped. Refer to Brake Shoe Replacement in Drum Brakes.
4. Remove the rear rotors, if equipped. Refer to Rear Brake Rotor Replacement in Disc Brakes.
5. Remove the propeller shaft. Refer to the appropriate procedure in Propeller Shaft:

•	Rear Propeller Shaft Replacement

•	Front Propeller Shaft Replacement

•	Two-Piece Propeller Shaft Replacement




6. Measure the amount of torque required in order to turn the pinion. Use an inch-pound torque wrench. Record this measurement for reassembly. This will provide the combined preload for the following components:

•	The pinion bearing

•

The seal

•	The carrier bearing

•	The axle bearing

•

The seal

7. Draw an alignment mark on the following components:

•	The pinion stem

•	The pinion flange

•	The pinion flange nut

8. Record the number of exposed threads on the pinion stem for reference.



9. Remove the pinion flange nut and washer. Hold the pinion flange using a J 8614-01 .



10. Remove the pinion flange using the J 8614-01 . Use a container in order to retrieve the lubricant.

Tools Required

J 8614-01 Companion Flange Holder

1. Apply a seal lubricant to the outside of the pinion flange.

Important: Do not hammer the pinion flange onto the pinion stem.

2. Install the pinion flange.




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.

3. Install the washer and a new nut.

Tighten
Tighten the nut on the pinion stem as close to the original marks as possible without turning the nut past the mark. Use the reference mark and the thread count as a reference. Tighten the nut slightly. Turn the pinion flange several times after each tightening in order to set the rollers.





Important: If the original preload torque value was less than 0.34 N·m (3 lb in), reset the torque specification to 0.34-0.56 N·m (3-5 lb in).

4. Measure the torque required to rotate the pinion, using an inch-pound torque wrench. Compare this value with the rotating torque recorded earlier. Continue to tighten and measure until you obtain the same preload.
5. Install the propeller shaft. Refer to the appropriate procedure in Propeller Shaft:

•	Rear Propeller Shaft Replacement

•	Front Propeller Shaft Replacement

•	Two-Piece Propeller Shaft Replacement

6. Install the rear rotors, if equipped. Refer to Rear Brake Rotor Replacement in Disc Brakes.
7. Install the drums, if equipped. Refer to Brake Shoe Replacement in Drum Brakes.
8. Install the rear wheels. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
9. Replenish the rear axle with new lubricant as needed.
10. Lower the vehicle.
