Information

Dimension X - center of wheel to lower edge of wing (rear axle shown)

* The entire threaded parts of the axle must be tightened in vehicle position. Vehicle position means: vehicle standing on the wheels, or the wheel suspension is raised with a universal vehicle lift. Dimension -X-, from lower edge of wing to center of axle corresponds to vehicle position. Always observe the following points.

Steel suspension
* The vehicle position is reached at the rear axle by pre-tensioning the steel spring using spring clamp 9823 to the dimension -X-.

Air suspension
* Vehicle position can be obtained on the rear axle by using PIWIS Tester II 9818 to bleed the relevant air spring and carefully raise the relevant wheel bearing housing until dimension -X- is reached.
