Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, lug wrench, torque wrench, socket set, bearing puller, and grease.
Safety Warnings: Ensure the vehicle is securely lifted and supported on jack stands before beginning any work. Use wheel chocks to prevent rolling.

2. Remove the Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and place it on jack stands.
Completely remove the lug nuts and take the wheel off.

3. Inspect the Wheel Bearing

Visual Inspection: Look for any signs of damage or corrosion on the bearing and surrounding components.
Play Test: Grasp the hub and check for any excessive movement.

4. Remove the Wheel Bearing

Remove the brake caliper and suspend it to avoid strain on the brake line. (Use a bungee cord or similar)
Remove the brake rotor if necessary, depending on the design.
Use a socket to remove the wheel hub assembly retaining bolts.
Use a bearing puller to carefully extract the bearing from the hub.

5. Install New Wheel Bearing

Preparation: Clean the hub area thoroughly and apply a thin layer of grease to the new bearing.
Position the new bearing into the hub and press it in evenly using a bearing installer or similar tool.
Reassemble the hub assembly, ensuring all bolts are tightened to manufacturer specifications.

6. Reassemble and Test

Reinstall the brake rotor and caliper.
Mount the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the recommended specification.
Conduct a test drive to ensure the issue is resolved.
