- Remove the brake caliper by unbolting it and securing it out of the way (do not let it hang by the brake line).
- Remove the brake rotor.
- Disconnect any ABS wiring or components as needed.
- Remove the wheel hub assembly by unbolting it from the steering knuckle.

4. Replace Wheel Bearing

Sub-steps:
- Use a bearing press to remove the old wheel bearing from the hub.
- Clean the hub area thoroughly.
- Press in the new wheel bearing into the hub, ensuring it is seated properly.

5. Reassemble the Wheel Assembly

Sub-steps:
- Reinstall the hub assembly onto the steering knuckle.
- Reattach the brake rotor and caliper.
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer's specifications.

6. Final Check

Sub-steps:
- Reconnect the battery.
- Spin the wheel by hand to ensure there’s no excessive resistance or noise from the new bearing.
