Tightening Pinion Shaft Nut
5. If the rotating torque is to low, use Holder 6719 to hold the pinion yoke, and tighten the pinion shaft nut in 6.8 Nm (5 ft. lbs.) until proper rotating
torque is achieved.
6. Align the installation reference marks and attach the propeller shaft to the yoke.
7. Check and add lubricant to axle, if necessary. Refer to Lubricant Specifications for lubricant requirements.
8. Install brake rotors and calipers.
9. Install wheel and tire assemblies.
10. Lower the vehicle.
Rear Axle - 9 1/4
REMOVAL
1. Raise and support the vehicle.
2. Scribe a mark on the universal joint, pinion yoke, and pinion shaft for reference.
3. Disconnect the propeller shaft from the pinion yoke. Secure the propeller shaft in an upright position to prevent damage to the rear universal joint.
4. Remove the wheel and tire assemblies.
5. Remove the brake drums to prevent any drag. The drag may cause a false bearing preload torque measurement.
6. Rotate the pinion yoke three or four times.
7. Measure the amount of torque necessary to rotate the pinion gear with a (inch lbs.) dial-type torque wrench. Record the torque reading for
installation reference.
8. Hold the yoke with Wrench 6719. Remove the pinion shaft nut and washer.
Yoke Removal
9. Remove the yoke with Remover C-452.
10. Remove the pinion shaft seal with suitable pry tool or slide-hammer mounted screw.
INSTALLATION
1. Clean the seal contact surface in the housing bore.
2. Examine the splines on the pinion shaft for burrs or wear. Remove any burrs and clean the shaft.
3. Inspect pinion yoke for cracks, worn splines and worn seal contact surface. Replace yoke if necessary.
NOTE: The outer perimeter of the seal is pre-coated with a special sealant. An additional application of sealant is not required.
4. Apply a light coating of gear lubricant on the lip of pinion seal.
