Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and place wheel chocks behind the rear wheels.
Disconnect the battery for safety.

2. Remove Wheel and Brake Assembly

Tools Required: Jack, jack stands, lug wrench, socket set
Loosen the lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake assembly.
Remove the brake caliper and bracket (use a torque wrench to ensure proper torque when reassembling).
Remove the brake rotor.

3. Remove and Inspect the Wheel Bearing

Tools Required: Bearing puller, socket set, torque wrench
Remove the hub assembly if necessary (this may involve removing additional components like the axle nut).
Inspect the wheel bearing for wear or damage, checking for roughness when spinning by hand.
If necessary, use a bearing puller to remove the old bearing.

4. Install New Wheel Bearing

Clean the hub area and apply bearing grease as needed.
Press the new wheel bearing into the hub assembly, ensuring it is seated properly.
Reassemble the hub to the vehicle, tightening all bolts to manufacturer specifications using a torque wrench.

5. Reassemble Brake Components and Wheel

Reinstall the brake rotor, caliper, and bracket, tightening to specified torque values.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern once it is on the ground.

6. Test Drive

Reconnect the battery and start the vehicle.
Test drive to ensure that the noise is resolved and check for any abnormal handling issues.
