Front Wheel Hub, Bearing, and Seal Replacement Independent
Removal Procedure
Tools Required
• | J 6368 Outer
Bearing Race Installer |
• | J 23448 Inner
Bearing Race Installer |
- Raise the vehicle. Support the vehicle with suitable safety stands.
- Remove the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires
and Wheels.
Notice: Support the caliper with a piece of wire to prevent damage to the brake
line.
- Remove the caliper. Refer to
Brake Caliper Replacement
in Disc Brakes.
- Remove the dust cap (5).
- Remove the following components:
- Remove the wheel hub/rotor (7).
• | Pull the hub/rotor free. Ensure that the outer wheel bearing (2)
comes free of the hub/rotor. |
• | Do not damage the steering knuckle spindle threads. |
- Remove the seal (10). Pry out the seal.
- Remove the inner wheel bearing (9).
- Remove the races (1, 8). Drive out each race using a brass
drift, inserted behind the race, in the notches in the hub.
- Clean grease from the hub/rotor and the steering knuckle spindle.
- Remove grease from inside the following components:
Notice: Do not spin the wheel bearings with compressed air to dry them-the
wheel bearings may be damaged.
- Use clean solvent and a small brush with no loose bristles.
- Inspect the wheel bearings and the races for damage or wear. Refer
to
Wheel Bearings Diagnosis
in
Suspension General Diagnosis. If a bearing or the race is damaged
or worn, replace the bearing and the race.
- Inspect the hub/rotor for the following conditions:
Installation Procedure
Notice: Start the races squarely inside the hub/rotor to avoid distortion and
possible cracking.
- Install the outer bearing race into the hub/rotor.
1.1. | Place the hub/rotor on the J 9746-02
and rest the assembly on the press bars. |
1.2. | Use the J 8092
in
order to drive the outer bearing outer race into position. |
- Turn over the hub/rotor.
2.2. | Drive in the inner bearing race using the J 23448
. |
Important:
• | Do not mix different greases because mixing may change the properties
of the greases, resulting in poor performance. |
- Apply a thin film of grease to the following components:
• | The steering knuckle spindle at the outer wheel bearing seat and
at the inner wheel bearing seat |
- Apply a small quantity of grease inboard of each wheel bearing
dust cap.
Notice: Failure to completely pack the wheel bearing (cones, rollers, and cage)
with grease will result in premature wheel bearing damage and/or wear.
- Fill each cone and roller assembly of the wheel bearing 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. |
- Install the inner wheel
bearing (9) into the hub/rotor. Apply an additional quantity of grease
outboard of this bearing.
- Install a new seal (10).
7.1. | In order to ensure that the seal is flush with the hub/rotor flange,
use a flat plate or block in order to install the seal. |
7.2. | Lubricate the seal lip with a thin layer of grease. |
- Install the hub/rotor (7). Do not damage the steering knuckle
spindle threads.
- Install the outer wheel bearing (2). Slide the bearing
over the spindle until the wheel bearing fully seats against the hub/rotor
outer race.
- Install the following components:
- Before the cotter pin is placed through the hole in the spindle,
adjust the wheel bearings.
- Adjust the wheel bearings. Refer to
Wheel Bearing Adjustment
.
- Install the new cotter pin (6).
13.1. | Make sure the bent pin ends do not interfere with the dust cap. |
13.2. | Apply an additional quantity of grease outboard of the wheel bearing. |
- Install the dust cap (5) on the hub/rotor (7).
- Install the caliper. Refer to
Brake Caliper Replacement
in Disc Brakes.
- Install the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires
and Wheels.
- Lower the vehicle.

- Remove the retainer cap.
- Remove the following components:
- Remove the wheel hub/rotor.
• | Pull the hub/rotor free from the spindle. Ensure that the outer
wheel bearing comes free. |
• | Do not damage the steering knuckle spindle threads. |
- Remove the inner wheel bearing. Pry out the seal.
- Remove the races. Drive out each race using a brass drift.
- Remove the rubber gasket from the spindle.
- Clean the grease off of the hub/rotor and the steering knuckle
spindle. Clean the grease from the inside of the hub.
Notice: Do not spin the wheel bearings with compressed air to dry them-the
wheel bearings may be damaged.
- Clean the grease off of the wheel bearings and the races. Use clean
solvent and a small brush with no loose bristles.
- Inspect the wheel bearings and the races for damage or wear. Refer
to
Wheel Bearings Diagnosis
in Suspension General Diagnosis. If a bearing or the race is damaged
or worn, replace the bearing and the race.
- Inspect the hub/rotor for the following conditions and repair
or replace the hub/rotor if necessary:
Installation Procedure

1.2. | Use the J 6368
in
order to drive the outer bearing race into position. |
- Remove the J 9746-02
and use a 7.6 cm (3 in) diameter bar in order to drive
the inner bearing race into position. Using a bar larger than 7.6 cm
(3 in) may damage the bearing seal seat.
Important:
• | Do not mix the greases because mixing may change the properties
of the grease, resulting in poor performance. |
- 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.
- Apply a small quantity of grease inboard of each wheel bearing
retainer cap.

until the wheel bearing fully seats against the hub/rotor outer race.
- Install the following components:
- Do not place the cotter pin through the hole in the spindle until
the wheel bearings are adjusted.
