VW front wheel hub. The hub is what your lug bolts thread into, and the center presses into the front wheel bearing. If your bearing is stuck to the hub, or the hub was damaged while removing the bearing, you'll need a new one. Make sure to check your lug bolts threads too, they can get damaged by cross threading. This particular wheel hub is for vehicles with 313mm brake discs on the front.

To guide you through this procedure we highly recommend you use the Bentley manual, so that you are setting everything up correctely.
