Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, lug wrench, torque wrench, socket set, and possibly a bearing puller.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which wheel bearing is being serviced.
Secure the vehicle on jack stands and ensure it is stable.

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

Remove the brake caliper by unbolting it and securing it out of the way (do not let it hang by the brake line).
Remove the brake rotor by pulling it off the hub.

5. Remove the Wheel Bearing

If applicable, remove the dust cap and cotter pin from the axle nut.
Use a socket or impact wrench to remove the axle nut.
Disconnect the wheel hub assembly from the vehicle by removing the mounting bolts.
If the wheel bearing is pressed into the hub, use a bearing puller to extract it.

6. Install New Wheel Bearing

Clean the hub area where the new bearing will be seated.
Install the new wheel bearing into the hub assembly, ensuring it is properly seated.
Reattach the hub assembly to the vehicle and secure it with bolts to the specified torque value (consult service manual for exact torque specifications).

7. Reassemble Brake Components and Wheel

Reinstall the brake rotor and caliper, ensuring all bolts are secured properly.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications.

8. Final Steps

Reconnect the negative battery terminal.
Test drive the vehicle to ensure the noise has been resolved.
