Installing rear wheel bearing: Installing

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
Tubular piece	VW 415 A	For pressing the wheel bearing out and in.
Pressure pieces P9247 (4 x)	P 9247/4	Use together with the tubular piece VW 415 A for pressing in the wheel bearing P9247/4.

1. Press in wheel bearing.

NOTE: 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.
