Front wheel camber, adjusting Note: - Install special tool as shown in illustration and
slightly pre-tension.
- Loosen suspension strut/wheel bearing housing
connection.
- Adjust camber by turning the spindle to specified
setting.
- Tighten suspension strut/wheel bearing housing
connection.
- Check camber and if necessary, repeat
adjustment. Slight cant of tool is permitted. Do not move steering with tool in place! Before adjusting camber, it is essential to
examine all suspension components for damage
(visual inspection) and to replace any damaged
parts. Because bolts with a shank diameter of 11 mm
diameter have been installed as standard it is no
longer necessary to replace bolts to correct
camber. Page 6 of 7Vehicle alignment12/7/2004http://ebahn.bentleypublishers.com/vw/servlet/Display?action=Goto&type=repair&id=VW.B4.SU01.44.1
