Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the 12V battery to prevent any electrical issues.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle from the manufacturer-recommended lift points.
Secure the vehicle on jack stands to ensure it is stable.

3. Remove the Wheel

Using a socket set, loosen the lug nuts and remove the wheel.
Inspect the brake components for any debris or damage.

4. Inspect and Remove the Wheel Bearing

Remove the brake caliper and rotor to gain access to the wheel bearing.
Use a socket set to remove the wheel hub assembly from the knuckle.
Carefully extract the wheel bearing using a bearing puller or press if necessary.

5. Install New Wheel Bearing

Clean the hub assembly and knuckle area thoroughly.
Insert the new wheel bearing into the hub using a press or hammer, ensuring it is seated properly.
Reassemble the wheel hub assembly to the knuckle, torqueing the bolts to manufacturer specifications.

6. Reinstall the Wheel

Reattach the rotor and brake caliper.
Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the specified value.
