WM 425819 Removing And Installing Rear Wheel Bearing (Except 911 Turbo S Coupe "Ed. 918 SPYDER", 911 CARRERA 4 GTS, 911 CARRERA 4 GTS CABRIO, 911 Gt3 RS 4.0): Information
Information
The wheel bearings adopt the function of the former ABS pulse rings. They are fitted with a so-called multipole seal. This is a seal with a magnetised layer, which generates the torque impulses for the ABS RPM sensors.
The multipole 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.
