Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, torque wrench, socket set, impact wrench (if available), and a clean work surface.
Safety Warnings: Ensure the vehicle is on a flat surface and use wheel chocks to prevent movement. Always wear safety glasses.

2. Lift the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on where the noise is coming from.
Secure the vehicle with jack stands to ensure stability.

3. Remove the Wheel

Loosen the lug nuts slightly while the wheel is still on the ground.
Remove the lug nuts completely and take off the wheel.

4. Inspect the Wheel Bearings

Visually inspect the wheel bearings for any signs of damage or excessive grease leakage.
Check for play by gripping the wheel at the 12 and 6 o'clock positions and rocking it back and forth. There should be no movement.
Spin the hub assembly while listening for any grinding noise.

5. Replace the Wheel Bearings (if needed)

Remove the brake caliper and bracket, securing it with a wire or bungee cord to avoid stress on the brake line.
Remove the rotor if necessary.
Use a socket set to remove the wheel bearing assembly from the hub.
Press out the old wheel bearings using a bearing puller or a suitable tool.
Clean the hub and install new bearings, ensuring they are properly seated.
Reassemble the hub, rotor, and brake components, following the torque specifications for all bolts.
