J 9746-02 Wheel Stud Remover
1. Raise the vehicle. Support the vehicle with suitable safety stands.
2. Remove the tire and wheel assembly.
3. Remove the brake caliper.
Notice: Support the caliper with a piece of wire to prevent damage to the brake line.
4. Remove the retainer/cap.
5. Remove the cotter pin, the nut, and the washer.
6. Remove the wheel hub/rotor.
^
Pull the hub/rotor free from the spindle. Make sure the outer wheel bearing comes free.
^
Do not damage the steering knuckle spindle threads.
7. Remove the inner wheel bearing. Pry out the seal.
8. Remove the races. Using a brass drift, drive out each race.
9. Clean any grease from the hub/rotor and the steering knuckle spindle. Clean any grease from inside the hub.
10. Using clean solvent and a small brush with no loose bristles, clean any grease from the wheel bearings and the races.
Notice: Do not spin the wheel bearings with compressed air to dry them-the wheel bearings may be damaged.
11. Inspect the wheel bearings and the races for damage or wear.
^
Refer to Wheel Bearings Diagnosis.
^
If a bearing or the race is damaged, replace both of these.
12. Inspect the hub/rotor for damage or wear.
^
Check for out of round or scored conditions.
^
Check for pitting or cracks.
^
If necessary, repair or replace the hub/rotor.
INSTALLATION PROCEDURE
1. Install the races into the hub/rotor.
1.1. Place the hub/rotor on the J 9746-02 Rest this assembly on the press bars.
1.2. Using a 7.6 cm (3 inch) diameter bar, or equivalent, press the outer bearing race into position.
1.3. Remove the J 9746-02 and use a 7.6 cm (3 inch) diameter bar, or equivalent, in order to press the inner bearing race into position. If the bar is
larger than 7.6 cm (3 inch), the bar may damage the bearing seal seat.
Notice: Start the races squarely inside the hub/rotor to avoid distortion and possible cracking.
2. Apply a thin film of grease to the steering knuckle spindle at the outer wheel bearing seat and at the inner wheel bearing seat, the shoulder, and the
seal seat.
Important:
^
Use an approved, high-temperature front wheel bearing grease in order to lubricate the bearings.
^
Do not mix different greases because mixing may change the grease properties, resulting in poor performance.
3. Apply a small amount of grease inboard of each wheel bearing retainer/cap.
4. Fill each wheel bearing (cone and roller assembly) full of grease.
^
Use a cone-type grease machine that forces grease into the bearing.
^
If a cone-type grease machine is not available, pack the wheel bearing by hand. When packing the wheel bearing by hand, work the grease into
the bearings between the rollers, the cones, and the cage.
Notice: Failure to completely pack the wheel bearing (cones, rollers, and cage) with grease will result in premature wheel bearing damage
and/or wear.
