Step-by-Step Approach to Replacing a Wheel Bearing
| Step |
Action |
| Loosen Lug Nuts: Use a lug wrench to loosen but not remove the lug nuts holding the wheel in place. |
Prevents accidental wheel rotation. |
| Jack Up Vehicle: Position a floor jack under the designated jack point and carefully lift the vehicle. |
Ensures safe access to the wheel assembly. |
| Remove Wheel: Completely remove the lug nuts and gently pull the wheel straight towards you to detach it from the hub. |
Exposes the wheel bearing for inspection. |
| Detach Caliper and Rotor: Disconnect the brake caliper and hang it securely using a wire or bungee cord. Remove the brake rotor to access the wheel bearing. |
Allows for the bearing to be removed. |
| Remove Old Bearing: Use a wheel bearing removal tool to detach the old bearing from the hub assembly. |
Facilitates the installation of the new bearing. |
| Install New Bearing: Carefully align and press the new bearing into place using a hammer or hydraulic press. |
Ensures proper fit and performance. |
| Reassemble Components: Reinstall the brake rotor, caliper, and wheel in reverse order. Torque the lug nuts to the specified tightness. |
Restores functionality and safety. |
