Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, wheel chock, 19mm socket (for lug nuts), torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is turned off.

2. Lift the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on which wheel bearing is being inspected.
Secure the vehicle on jack stands for safety.

3. Remove the Wheel

Use the lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake assembly and wheel bearing.

4. Inspect the Wheel Bearing

Check for play: With the wheel off, grasp the hub at 12 and 6 o'clock and check for any movement.
Spin the hub: Turn the hub by hand while listening for any grinding noises or roughness.
Inspect for damage: Look for signs of wear such as rust, pitting, or discoloration.

5. Replace if Necessary

If the bearing is found to be defective:
- Remove the brake caliper and rotor to access the bearing.
- Use a bearing puller to remove the old bearing from the hub.
- Clean the hub area and install the new bearing using a press if required.
- Reassemble in reverse order, ensuring all components are torqued to manufacturer specifications.
