Tools Required

Important: The ring gear and drive pinon gear may require replacement if the rear axle was operated for an extended period with loose differential drive pinion gear bearings.

1. Inspect the differential drive pinion gear bearing preload.
2. Remove the differential drive pinion flange. Refer to Drive Pinion Flange/Yoke and/or Oil Seal Replacement .



3. Place a block of wood (3) or otherwise support the drive pinion gear as it is driven from the differential housing.
4. Use a soft faced deadblow hammer to drive the pinion gear (1) from the differential housing (2).



5. Remove the differential drive pinion gear bearing spacer (1) from the differential drive pinion gear (2).
6. Remove the differential pinion gear inner bearing from the differential drive pinion gear.
7. Remove the differential drive pinion seal from the rear axle housing.



8. Perform the following steps in order to remove the inner bearing:

8.1.	Mount theJ 42154 on the J 42176 .

8.2.	Position the J 42154 firmly to one side of the bearing race.

8.3.	Use a hammer or press to drive the differential drive pinion gear inner bearing race from the differential housing while rotating the tool around the edge of the race.




9. Remove the differential drive pinion gear shim (1) from the differential housing (2).
10. Use the J 22912-B and a press in order to separate the drive pinion gear inner bearing from the drive pinion gear.



11. Remove the drive pinion gear outer bearing from the housing.
12. Use the J 42154 and the J 42176 with a deadblow hammer or a press in order to remove the bearing race.
