Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is turned off.
Disconnect the negative battery terminal for safety.

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove the Brake Components

Remove the brake caliper by taking out the caliper bolts (typically 14mm or 17mm).
Support the caliper with a bungee cord or similar to avoid strain on the brake line.
Remove the brake rotor by taking out the retaining screws if applicable.

4. Remove the Wheel Hub Assembly

Remove any dust covers from the hub.
Take out the axle nut (usually a 30mm socket) using a breaker bar.
Remove the hub assembly by taking out the bolts securing it to the steering knuckle (typically 12mm or 14mm).
Gently tap the hub assembly with a hammer if necessary to free it from the knuckle.

5. Inspect and Replace the Wheel Bearing

Check the bearing for smoothness; it should rotate freely without noise.
If the bearing is found defective, press out the old bearing using a bearing puller or hydraulic press.
Install the new bearing into the hub, ensuring it is seated correctly.
Follow the reverse order to reassemble the hub, rotor, and brake components.

6. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts to the manufacturer's torque specification (typically 76 ft-lbs).
