Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which bearing needs inspection/replacement.
Secure the vehicle on jack stands for safety.

3. Remove Wheel

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

4. Remove Brake Components (if necessary)

If replacing the front wheel bearing, remove the brake caliper by unbolting it and securing it out of the way.
Remove the brake rotor if it obstructs access to the wheel bearing.

5. Replace the Wheel Bearing

Remove the hub assembly using a socket and ratchet.
Replace the old wheel bearing with a new one, ensuring it is properly seated.
Reassemble the hub assembly, torquing to manufacturer specifications (typically around 80-100 ft-lbs).

6. Reinstall Brake Components

Reattach the brake rotor and caliper.
Ensure all bolts are tightened to the correct torque specifications.

7. Reinstall Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern to the manufacturer's torque specifications (typically 75-85 ft-lbs).

8. Test Drive

Start the vehicle and take it for a test drive to confirm the noise has been resolved.
