Required Tools (Not Included):

• Jack and Jack Stands
• Wheel Chocks
• Socket Set and Wrenches
• Bearing Puller / Press Tool (if required)
• Seal Driver Tool
• Grease / Lubricant
• Brake Cleaner

Installation Steps:

1. Prepare the Vehicle: Park the vehicle on a level surface, engage the parking brake, and place wheel chocks on the front wheels. Loosen the rear wheel lug nuts.
2. Lift and Secure: Jack up the rear of the vehicle and place it securely on jack stands. Remove the rear wheels.
3. Drain Axle Fluid (if applicable): If your axle requires it, drain the differential fluid.
4. Remove Axle Shaft: Carefully remove the components securing the axle shaft. This typically involves removing brake components, then unbolting the axle retainer plate or C-clips inside the differential. Slide the axle shaft out of the axle housing.
5. Remove Old Components: Once the axle shaft is removed, you will have access to the old bearing (OE# 1011291), bushing (OE# 1014207), and oil seals (OE# 1013794). Use appropriate tools (e.g., bearing puller, seal puller) to remove these components from the axle housing and/or axle shaft.
6. Clean the Area: Thoroughly clean the axle housing and axle shaft where the new components will be installed. Remove any old grease, dirt, or rust. Use brake cleaner if necessary.
7. Install New Oil Seals (OE# 1013794): Lightly lubricate the new oil seals with axle fluid or grease. Using a seal driver tool, carefully tap the new oil seals into their respective positions in the axle housing until they are seated flush. Ensure they are not bent or damaged during installation.
8. Install New Bearing (OE# 1011291) and Bushing (OE# 1014207): Depending on your axle design, the bearing and bushing may be pressed onto the axle shaft or into the axle housing. Apply a thin layer of grease to the bearing and bushing. Use a bearing press or appropriate driver to install the new bearing and bushing. Ensure they are fully seated and aligned correctly.
9. Reinstall Axle Shaft: Carefully slide the axle shaft back into the axle housing, ensuring it passes through the new oil seals, bushing, and bearing without damaging them.
10. Secure Axle Shaft: Reinstall the axle retainer plate or C-clips and any other components that secure the axle shaft. Reattach brake components.
11. Refill Axle Fluid (if applicable): If drained, refill the differential with the correct type and amount of axle fluid.
12. Reinstall Wheels: Mount the rear wheels and hand-tighten the lug nuts.
13. Lower Vehicle: Lower the vehicle to the ground and torque the lug nuts to the manufacturer's specifications.

8. Operating Instructions (Post-Installation)

After completing the installation, perform the following checks before operating the vehicle:

• Fluid Levels: Verify that the differential fluid level is correct (if applicable).
• Brake Function: Test the brakes at a low speed in a safe area to ensure proper operation.
• Listen for Abnormal Noises: Drive the vehicle slowly and listen for any unusual noises, such as grinding, humming, or squealing, which could indicate an installation issue or a defective component.
• Check for Leaks: Visually inspect the axle area for any fluid leaks after a short drive.

9. Maintenance

Proper maintenance can extend the life of your rear axle components:

• Regular Inspection: Periodically inspect the rear axle area for signs of wear, damage, or fluid leaks from the seals.
• Fluid Changes: Follow your vehicle manufacturer's recommendations for differential fluid change intervals.
• Lubrication: Ensure proper lubrication of all moving parts as specified by your vehicle's service manual.

10. Troubleshooting

If you encounter issues after installing the FOSA Rear Axle Bearing Kit, consider the following:

• Abnormal Noise (e.g., Screaming, Grinding):
  • Cause: Improper installation, insufficient lubrication, or a defective component.
  • Solution: Immediately cease operation. Re-check installation steps, ensuring all components are correctly seated and torqued. Verify proper lubrication. If noise persists, the component may be faulty and require replacement.
• Fluid Leaks:
  • Cause: Damaged or improperly seated oil seals.
  • Solution: Inspect the oil seals for damage or incorrect seating. Reinstall or replace seals as necessary.
• Loose Wheel:
  • Cause: Lug nuts not properly torqued, or axle shaft not fully secured.
  • Solution: Re-torque lug nuts to manufacturer specifications. Verify axle shaft retention.

If troubleshooting steps do not resolve the issue, it is recommended to consult a professional mechanic.
