Power steering gear, adjusting (ZF)

Note:
Two mechanics are required when adjusting.
Adjust with engine switched off.

- Raise vehicle on hoist.
- Wheels in straight-ahead position.
- By turning the steering wheel to and fro (about
30 to center axis) a knocking noise will be
heard if there is excessive play. - The second mechanic carefully screws the
adjustment screw -arrow- into the cover until the
knocking noise can no longer be heard inside the
vehicle.
- Complete a road test ensuring that when
maneuvering or negotiating corners the steering
self-centers without sticking. Page 59 of 99Steering12/7/2004http://ebahn.bentleypublishers.com/vw/servlet/Display?action=Goto&type=repair&id=VW.B4.SU01.48.1
