Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a hydraulic jack to raise the front or rear of the vehicle, depending on which wheel bearings are being serviced.
Secure the vehicle with jack stands.

3. Remove the Wheel

Use a tire iron to loosen the lug nuts.
Remove the lug nuts and take the wheel off.

4. Remove the Brake Components

Remove the brake caliper by unbolting it and securing it away from the rotor (do not let it hang by the brake line).
Take off the brake rotor by removing the retaining screws, if present.

5. Remove the Wheel Hub Assembly

Disconnect any ABS sensor wiring if applicable.
Remove the axle nut using a socket and breaker bar.
Unbolt the wheel hub assembly from the steering knuckle and pull it away from the vehicle.

6. Install New Wheel Bearing

Clean the mating surfaces on the hub and knuckle.
Press or tap the new wheel bearing into the hub assembly if not pre-assembled.
Reinstall the wheel hub assembly back into the steering knuckle.

7. Reassemble Components

Reattach the brake rotor and secure it with the retaining screws.
Reinstall the brake caliper and torque it to the manufacturer’s specifications.
Reinstall the wheel and tighten the lug nuts in a criss-cross pattern.

8. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
