Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, wheel chocks.
Safety Warnings: Ensure the vehicle is on a flat surface and use wheel chocks to prevent rolling.

2. Lift the Vehicle

Use the jack to raise the vehicle and secure it on jack stands.
Remove the wheel using the lug wrench.

3. Inspect the Wheel Bearing

Check for Play: With the wheel off, grasp the hub at 12 and 6 o'clock and shake. If there is play, the bearing may be faulty.
Spin the Hub: Rotate the hub by hand and listen for any grinding or roughness indicating a bad bearing.

4. Remove the Wheel Bearing

If faulty, proceed to remove the brake caliper and rotor for access.
Unbolt the wheel bearing assembly from the hub using a socket set. Use a torque wrench for reinstallation.

5. Install New Wheel Bearing

Clean the hub area where the new bearing will be installed.
Install the new wheel bearing, ensuring it is seated properly.
Reinstall the brake rotor and caliper, tightening to manufacturer specifications.

6. Reassemble and Lower Vehicle

Put the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value (consult the owner's manual for the correct torque setting).
