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

The following tools are required for installing the rear wheel bearing. 

Designation Special tool Explanation
Tube VW 415 A For pressing the wheel bearing out and in.

    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.

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

    Insert wheel bearing at the correct position, then press again on the wheel bearing housing with only slight force using a suitable pressure piece (9247/4), see pressure piece (4 x) 9247  and tube VW 415 A  .
