Rear axle final pinion bearing. Supports the pinion shaft within the differential carrier.

Professional installation required. Proper differential service is critical for drivetrain reliability:

1. Raise and secure the vehicle – Safely lift the rear axle and support on jack stands
2. Drain differential oil – Drain the lubricant from the rear axle differential
3. Remove the drive shaft – Mark orientation and remove the drive shaft
4. Remove the differential carrier – Remove the axle shafts and differential carrier assembly
5. Remove the old bearing – Carefully remove the old final pinion bearing using a bearing puller
6. Clean the differential housing – Thoroughly clean the housing, removing all old lubricant and debris
7. Inspect the pinion shaft and gears – Check for wear or damage; replace if necessary
8. Prepare the new bearing – Apply a thin coat of clean gear oil to the bearing
9. Install the new bearing – Press the new bearing onto the pinion shaft using a proper installation tool
10. Install the pinion assembly – Position the pinion assembly in the differential housing
11. Adjust bearing preload – Set pinion bearing preload per manufacturer specifications
12. Check gear backlash – Verify ring and pinion gear backlash is within specification
13. Install axle shafts and drive shaft – Reinstall axle shafts and the drive shaft
14. Refill with lubricant – Fill the differential with the correct grade and amount of gear oil
15. Test operation – Test drive the vehicle and check for smooth operation and unusual noise
16. Check for leaks – Inspect the differential housing for any lubricant leakage
