Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and secured with jack stands.
Disconnect the battery to prevent any electrical issues during repair.

2. Remove Wheel

Use a lug wrench to loosen lug nuts on the affected wheel.
Elevate the vehicle with a jack and secure it with jack stands.
Remove the wheel by completely unscrewing the lug nuts.

3. Remove Brake Components

Remove the brake caliper by unscrewing the caliper bolts; support it with a bungee cord to avoid straining the brake line.
Remove the brake rotor by unscrewing any retaining screws and pulling it off the hub.

4. Inspect and Replace Wheel Bearing

Inspect the wheel bearing assembly for any signs of wear or damage.
If replacement is necessary, remove the wheel bearing by unscrewing the retaining bolts and using a bearing puller if needed.
Install the new wheel bearing, ensuring it is seated correctly and secured with the appropriate torque specifications (typically around 30-50 ft-lbs, but check manufacturer specifications).

5. Reassemble Components

Reinstall the brake rotor and caliper, ensuring all bolts are tightened to manufacturer specifications.
Reattach the wheel, tightening the lug nuts in a star pattern to the specified torque (usually 100-150 ft-lbs).

6. Lower Vehicle

Carefully lower the vehicle off the jack stands and remove the jack.
Reconnect the battery and check the brake system for proper operation before taking the vehicle for a test drive.
