Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Torque wrench
- Bearing puller (if required)
- Clean rags
- Grease
Safety Warnings: Ensure the vehicle is on a flat surface and use jack stands to support the vehicle securely before working underneath.

2. Remove Wheel

Loosen the lug nuts on the wheel using a lug wrench while the vehicle is on the ground.
Jack up the vehicle and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect Wheel Bearing

Visual Inspection: Examine the wheel bearing for any signs of damage or excessive dirt.
Spin Test: Spin the hub by hand to check for smoothness; it should rotate freely without noise.
Rock Test: Grasp the hub and check for any play; there should be minimal to no movement.

4. Replace Wheel Bearing (if necessary)

Remove Hub Assembly:
- Remove the brake caliper and rotor.
- Detach any components obstructing access to the wheel bearing (e.g., ABS sensor, splash shield).
- Remove the hub assembly bolts using a socket set.
Replace Bearing:
- Use a bearing puller to remove the old bearing from the hub.
- Clean the hub area and install the new bearing, ensuring it is seated correctly.
- Reassemble the hub assembly by reversing the removal steps.

5. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Use a torque wrench to tighten the lug nuts to the manufacturer’s specified torque (typically around 90-100 ft-lbs for most models).
