Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface, and the parking brake is engaged.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which wheel bearing is suspect.
Place jack stands under the vehicle for added safety.

3. Remove the Wheel

Use a socket set to remove the lug nuts.
Take off the wheel and set it aside.

4. Remove the Brake Components

Remove the brake caliper by unbolting it and securing it to prevent strain on the brake line.
Take off the brake rotor by removing the retaining screws or clips.

5. Remove the Wheel Hub Assembly

Remove the axle nut using a socket and breaker bar; torque specifications should be checked in the repair manual.
Unbolt the wheel hub assembly from the knuckle (typically 3-4 bolts).
Carefully pull the hub assembly off the axle and out of the knuckle.

6. Inspect and Replace the Wheel Bearing

Check the wheel bearing for signs of wear, such as scoring or roughness.
If damaged, press out the old bearing using a bearing puller and press in a new wheel bearing using a hydraulic press, ensuring it is seated flush.

7. Reassemble Components

Reinstall the wheel hub assembly into the knuckle and secure it with the bolts, adhering to torque specifications.
Reattach the brake rotor and caliper.
Replace the axle nut and torque it to the specified value.

8. Reinstall the Wheel

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and use a torque wrench to tighten the lug nuts to the recommended torque.
