Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Elevate the Vehicle

Use a hydraulic jack to lift the vehicle and place it securely on jack stands.
Remove the wheel corresponding to the suspected faulty bearing using a socket set.

3. Remove the Brake Components

Remove the brake caliper by unbolting it and securing it out of the way (avoid stretching the brake line).
Remove the brake rotor by unscrewing any retaining screws or clips.

4. Inspect and Replace the Wheel Bearing

Remove the hub assembly from the knuckle by unbolting it. Use a torque wrench for proper reassembly.
Inspect the old bearing for any signs of wear or damage.
If replacement is needed, install the new wheel bearing using a bearing press or appropriate tools, ensuring it is seated correctly.

5. Reassemble Components

Reattach the hub assembly to the knuckle and torque the bolts to the manufacturer’s specifications.
Reinstall the brake rotor and caliper, ensuring all components are tightened properly.
Reinstall the wheel and torque the lug nuts to the recommended specifications.

6. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
Reconnect the negative battery terminal.
