Tools Required
J 42450-A Wheel Hub Resurfacing Kit
Removal Procedure
1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
2. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
Notice: Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from it's mount and the hydraulic flexible brake
hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may
cause damage to the brake hose and in turn may cause a brake fluid leak.
3. Remove the brake caliper and the caliper mounting bracket as an assembly from the suspension knuckle and support the assembly with heavy
mechanic's wire, or equivalent; ensure that there is no tension on the hydraulic brake flexible hose. Do NOT disconnect the hydraulic brake
flexible hose from the caliper. Refer to Brake Caliper Bracket Replacement - Front.
4. Remove the front wheel bearing assembly. Refer to Wheel Bearing/Hub Replacement - Front in Front Suspension.
5. Remove the splash shield from the steering knuckle.
Installation Procedure
Important: Whenever the rotor has been separated from the wheel bearing flange, clean any rust or contaminants from the wheel bearing flange and
the brake rotor mating surfaces. Failure to do this may result in increased lateral runout of the brake rotor, and brake pulsation.
1. Use the J 42450-A in order to clean any rust or corrosion from the wheel hub surface.
2. Clean any rust or contaminants from the steering knuckle to splash shield mating surfaces.
3. Install the splash shield to the steering knuckle.
4. Install the wheel bearing assembly. Refer to Wheel Bearing/Hub Replacement - Front in Front Suspension.
5. Install the brake caliper and the brake caliper bracket as an assembly to the suspension knuckle. Refer to Brake Caliper Bracket Replacement -
Front.
6. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tire and Wheels.
7. Lower the vehicle. See: Brake Caliper/Service and Repair/Brake Caliper Bracket Replacement - Front
