Use a floor jack to lift the vehicle and secure it with jack stands.
Remove the wheel covering the suspected faulty bearing.

3. Remove the Brake Components

Sub-steps:
- Remove the brake caliper by loosening the caliper bolts using a socket set.
- Suspend the caliper using a bungee cord to avoid stress on the brake line.
- Remove the brake rotor by unscrewing any retaining screws.

4. Remove the Hub Assembly

Sub-steps:
- Remove the axle nut using a socket and breaker bar.
- Unbolt the hub assembly from the steering knuckle.
- Carefully extract the hub assembly from the vehicle.

5. Inspect and Replace the Wheel Bearing

Sub-steps:
- Inspect the bearing for signs of damage, such as pitting or roughness.
- If replacement is necessary, press the new bearing into the hub using a bearing press.
- Ensure it is seated properly.

6. Reassemble Components

Sub-steps:
- Reinstall the hub assembly onto the steering knuckle.
- Secure with the appropriate torque specifications for the bolts.
- Reattach the brake rotor and caliper, ensuring all bolts are tightened to specification.

7. Lower the Vehicle

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

8. Reconnect Battery

Reconnect the battery and ensure all electrical connections are secure.
