Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, socket set, and wheel bearing puller.
Ensure the vehicle is on a flat surface and engage the parking brake. Disconnect the vehicle's negative battery terminal for safety.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which wheel bearings need inspection or replacement.
Secure the vehicle with jack stands to prevent it from falling.

3. Remove the Wheel

Using a lug wrench, loosen the lug nuts on the affected wheel while the vehicle is still on the ground.
Fully remove the lug nuts and take off the wheel.

4. Inspect the Wheel Bearing

Sub-steps:
- Visually inspect the wheel bearing for any signs of wear, such as discoloration or rust.
- Spin the hub to check for any roughness or noise.
- If the bearing is accessible, use a wheel bearing puller to remove it.

5. Replace the Wheel Bearing

Sub-steps:
- Clean the hub area where the bearing will be installed.
- Install the new wheel bearing into the hub using a bearing press or hammer, ensuring it is seated properly.
- Reinstall the wheel and hand-tighten lug nuts.

6. Lower the Vehicle

Carefully lower the vehicle from the jack stands using the jack.
Torque the lug nuts to the manufacturer's specifications (typically around 100-120 ft-lbs for most models).

7. Reconnect Battery

Reconnect the negative battery terminal.
