Wheel Hub: Service and Repair

Front Wheel Hub, Bearing, and Seal Replacement

Removal Procedure

1. Raise and suitably support the vehicle with safety stands.

Notice: Support the caliper with a piece of wire to prevent damage to the brake line.

2. Remove the brake caliper. Refer to Front Brake Caliper Replacement Service and Repair.






3. Remove the dust cap from the rotor.
4. Remove the cotter pin, the nut, and the washer.

Notice: Do not damage the outer bearing and the spindle threads.

5. Remove the wheel hub and bearing assembly from the spindle.
6. Remove the outer bearing.
7. Remove the seal. Pry the seal out and discard the seal.
8. Remove the inner bearing.
9. Clean all of the parts in a solvent, then air dry. Do not spin the bearings with compressed air.
10. Make sure all of the parts are clean and free of grease.
11. Inspect the rotor. Refer to Brake Rotor Thickness Variation Check or Brake Rotor Lateral Runout Check or Brake Rotor Tolerance Specifications.
12. Inspect the bearings and the races for wear or damage. Refer to Wheel Bearings Diagnosis Component Tests and General Diagnostics.






13. Remove the inner and outer races using J 29117-A , if necessary.

Installation Procedure

Important:
- Make sure that all of the parts are clean and free of grease.
- Apply an approved high-temperature front wheel bearing grease to the spindle at the inner and outer bearing seat, the shoulder, and the seal seat.
- Also, finger apply a small amount of grease inboard of each bearing cup in the rotor.
- Pressure pack the bearings with a grease machine or hand pack the bearings. Make sure the grease is worked thoroughly into the rollers, the cone, and the cage.






1. Install the inner and outer races, if necessary.
2. Install the inner bearing to the rotor.
3. Apply an additional quantity of grease outboard of the inner bearing.
4. Install the seal.
4.1 Lubricate the seal lip.
4.2 Use a flat plate in order to press the seal down flush with the hub.
4.3 Seat the outer bearing and the cup.

Important: Do not scuff the spindle threads.

5. Install the wheel and bearing assembly to the spindle.
6. Install the outer bearing to the rotor.
7. Install the washer.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

8. Install the spindle nut.

Tighten
8.1. Tighten the spindle nut to 16 Nm (12 lb ft), while turning the wheel assembly forward by hand.
8.2. Adjust the wheel bearings. Refer to Wheel Bearing Adjustment Adjustments.
8.3. Install new cotter pin. Bend the pin ends against the nut flats.
8.4. Install the dust cap to rotor.

9. Install the brake caliper. Refer to Front Brake Caliper Replacement Service and Repair.
10. Lower the vehicle.
