Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and support it securely with jack stands.
Remove the tires to access the wheel bearings.

3. Remove the Brake Assembly

Remove the caliper bolts using a socket set and hang the caliper using a bungee cord to avoid strain on the brake line.
Remove the brake rotor by unscrewing any retaining screws and sliding it off the hub.

4. Remove the Wheel Hub Assembly

Remove the axle nut using a socket wrench. This may require significant torque.
Disconnect any ABS sensor wires if present.
Remove the wheel hub assembly by extracting the bolts that secure it to the steering knuckle.

5. Inspect and Replace the Wheel Bearing

Inspect the wheel bearing for wear or damage. If damaged, proceed with replacement.
Use a bearing puller to remove the old bearing from the hub.
Press the new bearing into the hub using a hydraulic press, ensuring it is seated properly.

6. Reassemble Components

Reinstall the wheel hub assembly and secure it with the appropriate torque specifications for the bolts.
Reattach the brake rotor and caliper assembly, ensuring the caliper bolts are tightened to the specified torque.
Reinstall the tire and lower the vehicle back to the ground.

7. Final Checks

Reconnect the battery and perform a test drive to ensure the noise has been resolved.
