WM 405719 Removing And Installing Front Wheel Bearing (All Models): Information

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2012 Porsche Cayman, 2012 Porsche Boxster, 2011 Porsche Cayman, 2011 Porsche Boxster, and 2010 Porsche Cayman. However, it is still accessible from the selected car via links, so may be relevant.

Information

The wheel bearings adopt the function of the former ABS pulse rings. They are fitted with a so-called multiple seal. This is a seal with a magnetized layer, which generates the torque impulses for the ABS RPM sensors.

The multiple seal must not come into contact with highly magnetic parts. During installation, make sure that the magnetic side is facing the ABS sensor. Use test card 147-2 for this.
