• The wheel bearing has a magnetized multipole seal, which acts as a pulse sender for the wheel speed sensor. 
• The multipole seal -1- must always face upwards when the wheel bearing is set down (this does not apply when pressing the wheel hub into the wheel bearing). Do not damage the multipole seal and do not let it come into contact with magnetic objects (e.g. magnetized screwdriver or magnet). 

1. Press the wheel hub into the wheel bearing.
