Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle at the designated jacking points.
Secure with jack stands to ensure stability before proceeding.

3. Remove Wheel

Use a socket set to loosen and remove the lug nuts.
Take off the wheel to access the wheel hub and bearing.

4. Inspect and Replace Wheel Bearing

If bearing is faulty:
- Remove the brake caliper and rotor (use a torque wrench to note the torque specifications for reassembly).
- Disconnect any ABS sensor or brake line if necessary.
- Use a bearing puller to remove the old wheel bearing from the hub.
- Clean the hub area before installing the new bearing.
- Press the new bearing into the hub (ensure it is seated properly).

5. Reassemble Components

Reinstall the brake rotor and caliper (tighten to manufacturer specifications).
Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle back to the ground and then torque the lug nuts to the specified value.

6. Final Inspection

Double-check that all components are reinstalled correctly.
Ensure that the brake components are functioning properly and no tools are left in the wheel area.
