Solution

1. Preparation

Tools Required: Wheel chocks, jack, jack stands, lug wrench, torque wrench, bearing puller, socket set, and impact wrench.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety glasses and gloves.

2. Remove the Wheel

Loosen the lug nuts with a lug wrench while the vehicle is still on the ground.
Raise the vehicle using a jack, then secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove the Brake Components

Unbolt and remove the brake caliper using a socket set. Suspend it using a wire to avoid stress on the brake line.
Remove the brake rotor by unscrewing any retaining screws and sliding it off the hub.

4. Access the Wheel Bearing

Remove the hub assembly by unbolting it from the steering knuckle. Ensure the bolts are marked or noted for correct reinstallation.
Use a bearing puller to extract the old wheel bearing from the hub assembly by applying even pressure.

5. Install New Wheel Bearing

Clean the bearing housing area in the hub assembly with a clean cloth.
Apply a thin layer of grease to the new wheel bearing.
Install the new wheel bearing into the hub assembly, ensuring it is seated properly and flush.

6. Reassemble the Wheel Assembly

Reattach the hub assembly to the steering knuckle and torque the bolts to manufacturer specifications (consult the repair manual for exact torque values).
Slide the brake rotor back onto the hub and secure it with retaining screws.
Reinstall the brake caliper and ensure it is securely fastened.
Place the wheel back onto the hub and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle off the jack stands.
Torque the lug nuts to the specified value using a torque wrench.
