Unbolt the brake caliper using a socket and ratchet.
- Tools Required: Socket set
- Safety Warning: Do not let the caliper hang by the brake line; support it with a bungee cord.
Remove the brake rotor by taking off any retaining screws or clips.

4. Remove the Wheel Hub Assembly

Unbolt the wheel hub assembly from the steering knuckle; this may require a breaker bar for stubborn bolts.
Disconnect any ABS sensor wire if applicable.
Carefully pull the hub assembly off the axle shaft.

5. Replace the Wheel Bearing

Use a bearing puller to remove the old wheel bearing from the hub assembly.
Clean the hub assembly and install the new bearing using a press or suitable tool.
