Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, wheel chocks.
Safety Warnings: Ensure the vehicle is on a flat surface and secure it with wheel chocks before lifting.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is still on the ground.
Use the jack to lift the vehicle and securely place jack stands under the vehicle.
Completely remove the lug nuts and take off the wheel.

3. Inspect Wheel Bearing

Inspect the wheel hub for any signs of rust or damage.
Rotate the wheel hub by hand to assess for smoothness; listen for any grinding or roughness.
Check for any excessive play by rocking the hub back and forth as described in the diagnostic steps.

4. Replace Wheel Bearing (if necessary)

Remove Brake Components: If necessary, remove the brake caliper and rotor to access the wheel bearing.
- Use a torque wrench to remove bolts to avoid damage.
Remove Hub Assembly: Detach the hub assembly from the knuckle, typically using a socket set.
