Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked on a level surface.
Use wheel chocks to prevent movement and disconnect the vehicle's 12V battery for safety.

2. Elevate the Vehicle

Using a hydraulic jack, lift the front or rear of the vehicle based on which wheel bearing is being inspected.
Secure the vehicle with jack stands to ensure stability.

3. Remove the Wheel

Using a lug wrench, remove the wheel by loosening the lug nuts in a star pattern.
Take off the wheel and place it aside safely.

4. Inspect the Wheel Bearing

Visually check for any signs of damage or rust on the wheel bearing assembly.
If necessary, remove any dust cover or shield to access the wheel bearing.

5. Test the Bearing

Spin the wheel hub by hand. It should rotate smoothly without any grinding noise or resistance.
If noise is detected, the wheel bearing is likely faulty and needs replacement.

6. Replace the Wheel Bearing (if bad)

Remove the retaining clips and bolts securing the wheel bearing to the hub.
Use a bearing puller to carefully extract the old bearing from the hub.
Install the new wheel bearing by reversing the removal process, ensuring it is seated correctly.
Torque the bolts to the manufacturer's specifications.

7. Reassemble the Wheel

Reinstall the wheel onto the hub and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified values using a torque wrench.
