3. Remove Brake Components

Remove the caliper by loosening the caliper bolts with a socket.
Suspend the caliper using a hanger to avoid straining the brake line.
Take off the brake rotor by removing the rotor retaining screws if present.

4. Remove Wheel Hub Assembly

Remove any retaining clips or bolts securing the hub assembly.
Use a bearing puller to extract the hub assembly from the steering knuckle.
Clean the area where the new bearing will be installed.

5. Install New Wheel Bearing

Press the new wheel bearing into the hub assembly using a bearing press tool.
Reinstall the hub assembly back into the steering knuckle, ensuring proper alignment.
Secure it with the retaining clips or bolts to the manufacturer’s torque specifications.

6. Reassemble Brake Components

Reinstall the brake rotor and secure with screws.
Reattach the caliper and tighten the caliper bolts to the specified torque.
