Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Socket set
- Torque wrench
- Safety glasses and gloves
Safety Warnings:
- Ensure vehicle is on a flat surface before lifting.
- Always use jack stands after lifting the vehicle.

2. Remove Wheel

Loosen the lug nuts using a lug wrench.
Use the jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Wheel Bearing

Check for Wheel Play: Re-grasp the wheel at the 12 and 6 o'clock positions and feel for any movement.
Spin the Hub Assembly: Rotate the hub by hand and listen for grinding or roughness.

4. Replace Wheel Bearing (if faulty)

Remove Brake Caliper: Unbolt the caliper from its mounting bracket and secure it using a wire or bungee cord to avoid strain on the brake line.
Remove Brake Disc: Unscrew the bolts holding the brake disc and remove it.
Remove Hub Assembly: Remove any retaining bolts or nuts securing the hub assembly and pull the hub away from the steering knuckle.
Replace Bearing: Press out the old bearing using a bearing puller. Press in the new bearing using a bearing press.
Reassemble Components: Reinstall the hub assembly, brake disc, and caliper, ensuring all bolts are torqued to manufacturer's specifications.

5. Reinstall Wheel

Place the wheel back on the hub.
Hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the manufacturer’s torque specifications.
