Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety gloves and goggles for protection.

2. Lift the Vehicle

Use a jack to raise the vehicle and secure it on jack stands.
Remove the wheel using a socket set.

3. Inspect and Remove the Wheel Bearing

Visual Inspection:
- Look for any signs of wear or damage on the bearing and surrounding components.
Remove the Brake Caliper:
- Unbolt the caliper and secure it to the suspension using a bungee cord to avoid stress on the brake line.
Remove the Rotor:
- Take off the brake rotor by removing any retaining screws or bolts.
Remove the Wheel Hub Assembly:
- Unbolt the hub assembly from the steering knuckle, noting the orientation of all components.
Replace the Wheel Bearing:
- If the bearing is integrated into the hub, replace the entire hub assembly; otherwise, press out the bad bearing using a bearing press and install a new one.

4. Reassemble Components

Reinstall the wheel hub assembly, ensuring bolts are torqued to manufacturer specifications (typically around 85-100 lb-ft, but confirm with a service manual).
Reattach the rotor and caliper, ensuring proper alignment and torque specifications.
Reinstall the wheel and lower the vehicle.

5. Final Checks

Perform a test drive to verify the repair, listening for any abnormal noises.
