Pressing in and pressing out wheel bearing — VW

The following description deals with the Audi TT 1999 ä. Therefore differences must be considered, if necessary.

Special tools and workshop equipment required

V.A.G 1383 A Gearbox lifter

V.A.G 1389 A/1 Foot pump with high pressure hose

If hand pump V.A.G 1389/1 is already available, this can be converted to a foot pump using:
