Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, wheel chock, socket set, torque wrench.
Ensure that the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to ensure safety while working on electrical components (if applicable).

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts on the wheel.
Lift the vehicle with a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Remove the Brake Caliper and Rotor

Remove the bolts securing the brake caliper using a socket and ratchet.
Carefully lift the caliper and support it using a bungee cord or similar device to avoid stress on the brake line.
Remove the brake rotor by taking out any retaining screws if present.

4. Remove the Wheel Hub Assembly

Remove any dust cover or protective cover from the hub assembly.
Unscrew the bolts securing the hub assembly, typically found on the rear of the assembly.
Disconnect any wiring related to the wheel bearing if equipped with a sensor.
Pull the hub assembly straight off the axle, being careful not to damage adjacent components.

5. Install New Wheel Bearing

Place the new wheel bearing or hub assembly in position and push it onto the axle.
Reattach the retaining bolts and tighten to manufacturer specifications using a torque wrench.
Reconnect any electrical connectors and replace the dust cover.

6. Reassemble Brake Components

Reinstall the brake rotor and secure it with any retaining screws.
Reattach the brake caliper and secure it with the bolts.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle off the jack stands.
Use the torque wrench to tighten the lug nuts to the manufacturer’s specifications.
