Solution

1. Preparation

Gather tools including a jack, jack stands, and a torque wrench.
Ensure the vehicle is parked on a level surface and turn off the ignition.

2. Lift and Secure the Vehicle

Use the jack to lift the vehicle from the designated jacking points.
Place jack stands under the vehicle to secure it safely.

3. Remove the Wheel

Using a socket set, remove the lug nuts and take off the wheel to access the hub assembly.
Keep the lug nuts in a safe place for reinstallation.

4. Inspect the Wheel Bearing

Look for any signs of physical damage to the wheel bearing and hub assembly.
Check for any grease leakage, which may indicate a failing bearing.
Rotate the hub by hand to feel for roughness or binding.

5. Replace the Wheel Bearing (if necessary)

Remove the old bearing: If the bearing is bad, use a bearing puller to remove it from the hub.
Install the new bearing: Press the new bearing into the hub using a bearing press, ensuring it is seated properly.
Reassemble the wheel: Reattach the wheel to the hub, hand-tighten the lug nuts, and then use a torque wrench to tighten them to the manufacturer's specifications (typically around 80-100 ft-lbs).

6. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
