Removal & Installation
- Before servicing the vehicle, refer to the Precautions section.
- Drain the differential of fluid.
Remove or disconnect the following:
- Check and record the bearing preload with an inch lb. torque wrench.
- Hold the pinion flange using special tool C-3281 or equivalent and remove the collared nut.
Pry out the pinion flange seal.
Use a new pinion nut for assembly.
- Install the new pinion seal using special tool 9321 drift and a mallet. Tighten the pinion nut to 133 ft. lbs. (180 Nm).
- Check the bearing preload. The bearing preload should be equal to the reading taken earlier.
- If the preload torque is low, tighten the pinion nut in 44 inch lb. (5 Nm) increments until the torque value is reached.
- If the pinion bearing preload torque cannot be attained at maximum pinion nut torque, replace the collapsible spacer.
Install or connect the following:
Fill the axle assembly to correct level.
