1. Press in wheel bearing.
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 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.
Heat up wheel bearing housing before pressing in the wheel bearing.
