Rear wheel bearings are serviced by replacement only, as they are usually damaged when removed.
The rear wheel bearings are permanently sealed and lubricated and do not require any routine maintenance. Removing and installing the bearing on the car requires a special puller. If the necessary tools are not available, this work is best left to an authorized Porsche dealer or other qualified repair shop.
Check the wheel bearing with the wheel off the ground and the car properly supported. Spin the wheel and listen for any roughness. Alternately, apply pressure to either side of the wheel while checking for play. If any faults are found and no suspension components are found to be at fault, the wheel bearing should be replaced.
