Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, mechanic's stethoscope, torque wrench, wheel bearing puller.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the battery if working on electrical components.

2. Remove Wheel

Loosen the lug nuts with a lug wrench.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Wheel Bearing

Inspect: Check the wheel bearing for damage or excessive play.
Remove: Use a wheel bearing puller to extract the old bearing from the hub assembly.
Clean: Clean the hub area thoroughly to remove any debris or old grease.
Install: Place the new wheel bearing into the hub, ensuring it is seated properly.
Reassemble: Reattach the wheel hub and torque the lug nuts to the manufacturer’s specifications (typically around 90-120 lb-ft for Porsche).

4. Reinstall Wheel

Put the wheel back on and secure it with the lug nuts finger-tight.
Lower the vehicle from the jack stands.
Tighten the lug nuts to the specified torque using a torque wrench.

5. Final Checks

Reconnect the battery if it was disconnected.
Perform a road test to ensure the noise has been resolved and that the wheel bearing operates smoothly.
