Drive Pinion Assemble

^ Tools Required
- J 42148 Pinion Bearing Race Installer
- J 42176 Driver Handle





1. Install the differential drive pinion gear outer bearing outer race to the housing using the J42148, the J42176 and a dead blow hammer or press.

Important: Lubricate the differential drive pinion gear outer bearing with rear axle lubricant prior to installation.

2. Install the differential drive pinion gear outer bearing into the housing.
3. Install the pinion seal.





4. Install the correct pinion shim (1) to the differential housing (2).





5. Using the J42176 and the J4214S, install the inner bearing race to the differential housing with a deadblow hammer or a press.





6. Lubricate the differential drive pinion gear inner bearing and the drive pinion gear shaft with rear axle lubricant and use a press to install the differential drive pinion gear inner bearing (2) to the differential drive pinion gear (1).





7. Install the differential drive pinion gear bearing spacer (1) onto the differential drive pinion gear (2).
8. Install the drive pinion gear into the rear axle housing and set pinion depth.
9. Install the differential drive pinion seal and flange.





10. Rotate the differential drive pinion gear several times to assure that the inner and the outer bearings have been seated.
11. If installing a new differential ring and pinion gearset, perform the gear tooth contact pattern check.
12. Using a torque wrench (2), inspect the preload.
13. Reset the preload to the proper specifications, if the preload was reduced by rotating the differential drive pinion gear.
