Press out wheel bearing with tubular piece VW 415A (tool Q using the appropriate shims.
- Press inner wheel bearing race off the wheel hub.
To do this, use pressure piece P 297a (tool A) in combination with the separator (tool B).

NOTE:
- First pull the inner bearing race several millimeters off the wheel hub so that the separator can be put into place.
- For this purpose, use a two-claw puller in combination with a suitable pressure piece.

Installation
