Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Elevate the Vehicle

Use a floor jack to lift the vehicle and position jack stands securely under the vehicle's frame.
Tools Required: Floor jack, jack stands

3. Remove Wheel

Use a lug wrench to loosen and remove the wheel lug nuts.
Remove the wheel from the hub assembly.
Tools Required: Lug wrench, possibly a torque wrench for reinstallation

4. Inspect Wheel Bearing

Check for visible damage or corrosion around the wheel bearing.
Grasp the wheel hub and check for any play or movement.
Rotate the hub and listen for noise. If it feels rough or sounds noisy, the bearing is likely worn out.

5. Replace Wheel Bearing (if necessary)

Remove the brake caliper and rotor to access the wheel bearing.
- Sub-steps:
  - Unbolt the brake caliper and support it using a bungee cord (do not let it hang by the brake line).
  - Remove the brake rotor.
Remove the wheel bearing assembly from the hub using a puller tool if necessary.
Install the new wheel bearing by pressing it into place. Ensure it is seated properly.
Reinstall the rotor and caliper, and ensure all bolts are torqued to manufacturer specifications.
Tools Required: Brake caliper tool, bearing puller, torque wrench

6. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications.
Tools Required: Torque wrench
