Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly before lifting the vehicle.
Lift the vehicle using a hydraulic jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Remove Brake Components

Remove the brake caliper by unbolting it from the bracket using a socket wrench. Hang it safely with a bungee cord to avoid stress on the brake line.
Take off the brake rotor by removing any retaining screws and sliding it off the hub.

4. Remove Wheel Bearing Assembly

Remove any dust caps or retaining rings securing the wheel bearing.
Unbolt the wheel bearing assembly from the hub using the appropriate socket.
Carefully pull the wheel bearing assembly out of the hub.

5. Inspect and Replace

Inspect the old wheel bearing for any signs of damage or wear.
Install the new wheel bearing into the hub, ensuring it is seated correctly.
Reattach the retaining ring or dust cap to secure the bearing in place.

6. Reassemble Components

Reinstall the brake rotor onto the hub.
Reattach the brake caliper and ensure it is secured properly.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower Vehicle and Final Checks

Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications (typically around 90-120 ft-lbs for Cayenne).
Reconnect the battery.
