42 58 19 Removing and installing rear wheel bearing - as of MY 2005 (All Models): Information: Information
NOTE:
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 magnetized 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.
