and fall to the floor. - Remove O-ring -arrow- from groove. - Mark installation positions of parts -1-, -2- and -3-. Noises while driving may result if the indicated
parts are not reassembled to their prior positions. Use a waterproof felt-tipped pen for marking
parts.
- Remove rubber gasket (arrow) from groove. - With triple-rotor joint housing clamped in vise, pull
axle shaft together with triple-rotor star upward out

Vehicle alignment

Test requirements:
Measuring equipment correctly calibrated
Vehicle unladen1)

Tires inflated to correct pressure
Vehicle accurately aligned, suspension
bounced and rocked several times
Suspension, steering and steering linkage
checked for excessive play and damage.

Note:
Vehicle alignment should not be checked
before the vehicle has completed 1000 to 2000
km (600 to 1200 miles) as then the coil springs
have had time to settle.
The cause of vehicle imbalance may also be,
excessive residual imbalance and/or vertical
wheel runout.
1)
Unladened means: the weight of the vehicle
ready for the road (fuel tank completely filled,
spare wheel, vehicle tools and vehicle jack). Page 1 of 7Vehicle alignment12/7/2004http://ebahn.bentleypublishers.com/vw/servlet/Display?action=Goto&type=repair&id=VW.B4.SU01.44.1
