Replacing rear wheel bearing: Notes

Information 

• The wheel bearing has a magnetized multiple seal, which acts as a pulse sender for the wheel speed sensor  .
• The multiple-pole 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 multiple seal and do not come into contact with magnetic objects (e.g. magnetized screwdriver, magnet)  .
