Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Torque wrench
- Wheel chocks
Safety Warnings: Ensure the vehicle is on a flat surface and engage the parking brake before lifting.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is still on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Wheel Bearing

Visual Check: Look for any visible damage to the wheel bearing assembly.
Check for Play: With the wheel removed, grasp the hub at 12 and 6 o'clock and push/pull to check for excessive play.
Spin the Hub: Rotate the hub by hand and listen for grinding or roughness.

4. Replace Wheel Bearing (if necessary)

Remove Brake Assembly: If the wheel bearing is faulty, remove the brake caliper and rotor.
Remove Wheel Hub: Detach the wheel hub from the steering knuckle by removing the bolts securing it.
Install New Bearing: Press in the new wheel bearing using a bearing press or appropriate tool, ensuring it is seated properly.
Reassemble Components: Reattach the hub to the steering knuckle, install the brake rotor and caliper, and ensure all fasteners are torqued to specifications.

5. Reinstall Wheel

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
