Solution

1. Preparation

Gather necessary tools and parts for the repair.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent any electrical issues during the repair.

2. Remove Wheel

Loosen the lug nuts of the affected wheel while the vehicle is on the ground.
Elevate the vehicle with a hydraulic jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Remove Brake Components

Remove the brake caliper using a socket set, supporting it with a bungee cord to avoid straining the brake line.
Remove the brake rotor by unscrewing the retaining screws if applicable.

4. Remove the Wheel Hub Assembly

Remove the axle nut using a torque wrench to ensure it is properly loosened.
Unscrew the bolts holding the wheel hub assembly in place.
Carefully detach the hub from the spindle.

5. Replace Wheel Bearing

Press out the old wheel bearing using a bearing press or hammer if necessary.
Clean the hub assembly and insert the new wheel bearing, ensuring it is seated properly.
Use the bearing press to install the bearing if applicable.

6. Reassemble Components

Reattach the wheel hub assembly to the spindle and secure it with bolts.
Reinstall the brake rotor and brake caliper.
Put the wheel back on and hand-tighten the lug nuts.

7. Lower the Vehicle

Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications.
