Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel and Brake Components

Tools Required: Socket set, lug wrench, brake caliper tool
Sub-steps:
1. Loosen the lug nuts on the wheel while the vehicle is on the ground.
2. Lift the vehicle using a hydraulic jack and secure it with jack stands.
3. Remove the wheel by taking off the lug nuts completely.
4. Remove the brake caliper by unbolting it and suspending it using a wire (do not let it hang by the brake line).
5. Take off the brake rotor to expose the hub assembly.

3. Replace the Wheel Bearing

Tools Required: Bearing puller, socket set, torque wrench, hammer, grease
Sub-steps:
1. Remove the hub assembly by unbolting it from the steering knuckle.
2. Use a bearing puller to extract the old wheel bearing from the hub.
3. Clean the hub and apply a thin layer of grease to the new wheel bearing.
4. Press the new wheel bearing into the hub using a bearing press or carefully hammer it in while ensuring it is seated evenly.
5. Reinstall the hub assembly back onto the steering knuckle and torque the bolts to the manufacturer's specifications.

4. Reassemble Brake Components and Wheel

Sub-steps:
1. Reinstall the brake rotor onto the hub.
2. Reattach the brake caliper, ensuring it is secured properly.
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle back to the ground and torque the lug nuts to the specified value.

5. Final Checks

Reconnect the negative battery terminal.
Test the new bearing by spinning the wheel to ensure no binding or noise is present.
