Wheel Hub: Service and Repair

FRONT HUB/BEARING

REMOVAL PROCEDURE
^ Tools Required:
- J 29117-A Front Outer Race Remover

1. Raise the vehicle. Support the vehicle with safety stands.
2. Remove the tire and wheel assembly. Refer to WHEEL REMOVAL in TIRES AND WHEELS.
3. Remove the brake caliper. Refer to BRAKE CALIPER REPLACEMENT in DISC BRAKES.





4. Remove the dust cap from the rotor/hub.





5. Remove the cotter pin, the hub nut, the washer, and the outer wheel bearing.





6. Remove the rotor/hub.
^ Do not damage the spindle threads.
^ The inner wheel bearing will remain inside the rotor.





7. Remove the inner wheel bearing seal.
7.1. Pry out the seal and discard.
7.2. Remove the inner wheel bearing from the rotor/hub.





8. Remove the inner and the outer bearing races using the J 29117-A.

NOTICE: Do not spin the wheel bearings with compressed air to dry them the wheel bearings may be damaged.

9. Clean any grease from the rotor/hub, the spindle, and the wheel bearings using clean solvent and a small brush with no loose bristles.
10. Inspect the rotor/hub. Refer to BRAKE ROTOR THICKNESS VARIATION CHECK or BRAKE ROTOR LATERAL RUNOUT CHECK or BRAKE ROTOR TOLERANCE in DISC BRAKES.
11. Check the wheel bearings and the races for damage or wear. Refer to WHEEL BEARINGS DIAGNOSIS in SUSPENSION GENERAL DIAGNOSIS.

INSTALLATION PROCEDURE





1. Using a brass drift, install the bearing races into the rotor/hub.

Important:
^ Use an approved high-temperature front wheel bearing grease. Refer to RECOMMENDED FLUIDS AND LUBRICANTS in MAINTENANCE AND LUBRICATION.
^ Do not mix the greases. Mixing may change the properties of each grease used, resulting in poor performance.

2. Apply a thin film of grease to the spindle at the outer and the inner wheel bearing seat, the shoulder, and the seal seat.
3. Apply a small quantity of grease inboard of each wheel bearing cup inside the rotor/hub.

NOTICE: Failure to completely pack the wheel bearing (cones, rollers, and cage) with grease will result in premature wheel bearing damage and/or wear.

4. Fill the wheel bearing, cone and roller assemblies, full of grease.
^ Use a cone-type grease packer that forces grease into the bearing.
^ If a cone-type grease packer is not available, pack the wheel bearings by hand.
^ If the wheel bearings are packed by hand, work the grease into the bearings between the rollers, the cones, and the cage.
5. Install the inner wheel bearing into the rotor/hub. Apply an additional quantity of grease outboard of this wheel bearing.
6. Install a new seal.
6.1. Use a flat-surfaced tool in order to install the seal so that the seal is flush with the rotor/hub flange.
6.2. Lubricate the seal lip with a thin layer of grease.





7. Install the rotor/hub. Do not damage the spindle threads.





8. Install the outer wheel bearing. Press on the spindle until the wheel bearing fully seats against the rotor/hub outer bearing.

NOTICE: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.

9. Install the washer and the nut.

Tighten
Tighten the rotor/hub nut to 16 Nm (12 lb ft), while turning the wheel assembly forward.

10. Apply an additional quantity of grease outboard of the wheel bearing.
11. Adjust the wheel bearings. Refer to WHEEL BEARING ADJUSTMENT.
12. Install the cotter pin.





13. Install the cap on the rotor/hub.
14. Install the brake caliper. Refer to BRAKE CALIPER REPLACEMENT in DISC BRAKES.
15. Install the tire and wheel assembly. Refer to WHEEL INSTALLATION in TIRES AND WHEELS.
16. Remove the safety stands.
17. Lower the vehicle.
