Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Raise the Vehicle

Use a jack to lift the front or rear (depending on the suspected bearing) of the vehicle.
Secure it with jack stands to ensure safety.

3. Remove the Wheel

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

4. Inspect and Remove the Wheel Bearing Hub Assembly

Locate the wheel bearing hub assembly.
Remove brake caliper bolts and hang the caliper using wire (do not let it hang from the brake line).
Take off the brake rotor.
Remove the hub assembly by unscrewing the retaining bolts (usually 3-4 bolts).
Carefully pull the hub assembly away from the steering knuckle.

5. Replace the Wheel Bearing

If the bearing is integrated into the hub assembly, replace the entire hub assembly.
If the bearing is separate, press the old bearing out using a bearing puller.
Clean the mounting surface and press the new bearing into place, ensuring it is seated correctly.

6. Reassemble

Reinstall the wheel hub assembly, torque the retaining bolts to the manufacturer’s specifications (usually around 80-100 ft-lbs).
Reattach the brake rotor and caliper, ensuring all bolts are tightened to specifications.
Put the wheel back on and torque the lug nuts in a crisscross pattern to the recommended torque (typically 76-90 ft-lbs).

7. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
