Installing Rear Wheel Bearing

The following tools are required for installing the rear 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 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. 

1. Fit (press in) wheel bearing at the correct position.

   Before installation, clean the bore in the wheel bearing housing and remove edges with a polishing cloth.

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

   Preparatory condition: → Temperature: 100°C+20°C 

   Fit wheel bearing at the correct position. Then press again on the wheel bearing housing with only slight force using a suitable pressure piece -2-  (9247/3), see pressure pieces (4x) 9247  and -1- tube VW 415 A.
