Drive Pinion

Removal Procedure

^ Tools Required
- J22536 Pinion Driver
1. Remove the differential carrier.
2. Measure the differential drive pinion gear inner and outer bearing preload.
3. If a preload measurement cannot be obtained, inspect for looseness of the drive pinion gear. The following conditions may cause looseness:
^ A worn drive pinion gear yoke
^ Defective inner or outer drive pinion gear bearings

4. If the rear axle was operated for an extended period with very loose inner and outer drive pinion gear bearings, the following components will require replacement:
^ The ring gear
^ The drive pinion gear





5. Remove the differential drive pinion gear yoke (1).





6. With channel-locking pliers (4) and a wrench (1), Install J22536 to the differential drive pinion gear (2).





7. Apply heavy hand pressure on J22536 toward the rear axle housing (2). This pressure keeps the outer drive pinion gear (1) bearing seated in order to avoid damage to the outer race.

Outer Bearing

Removal Procedure
1. Remove the differential drive pinion gear seal from the rear axle housing.
2. Remove the drive pinion gear outer bearing from the rear axle housing.
3. Use a punch in order to remove the drive pinion gear outer bearing race from the rear axle housing, if the drive pinion gear outer bearing is being replaced. Place the punch into the slots in the rear axle housing, alternating from side to side in order to evenly work the bearing race from the rear axle housing.

Inner Bearing

Removal Procedure

^ Tools Required
- J22912-01 Rear Pinion Bearing Cone Remover
1. Remove the drive pinion gear bearing spacer from the drive pinion gear. Discard the drive pinion gear bearing spacer.
2. Use a punch in order to remove the drive pinion gear inner bearing race from the rear axle housing, if the inner drive pinion gear bearing is being replaced. Place the punch into the slots in the rear axle housing, alternating from side to side in order to evenly work the bearing race from the rear axle housing.





3. Use the J22912-01 in order to drive the inner drive pinion gear bearing from the drive pinion gear.
