Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Torque wrench
- Wheel bearing puller (if replacement is necessary)
- OBD-II scanner (for ABS codes)
Safety Warnings:
- Ensure the vehicle is on a flat surface and securely lifted before working on it.
- Always wear safety glasses and gloves.

2. Lift Vehicle

Park the vehicle on a level surface and engage the parking brake.
Loosen the lug nuts on the wheel associated with the suspected bad bearing.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel.

3. Inspect Wheel Bearing

Check the wheel hub for any visible signs of damage or excessive grease leaking.
Rotate the wheel hub by hand and listen for any noise or roughness.
If available, use a dial indicator to measure any axial or radial play.

4. Replace Wheel Bearing (if necessary)

Remove Hub Assembly:
- Remove the brake caliper and rotor.
- Disconnect any ABS sensor wiring if present.
- Remove the bolts securing the hub assembly.
Install New Bearing:
- Press the new bearing into the hub using a bearing press or appropriate tool.
- Reassemble the hub assembly in reverse order.
- Torque the hub assembly bolts to manufacturer specifications.
