32 11... Notes on checking steering backlash on vehicles with rack-and-pinion steering: Notes
WARNING: This page is about a different car, the 2011 BMW 750xi, 2011 BMW 750Lxi, 2010 BMW 750xi, and 2010 BMW 750Lxi. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The evaluation "steering backlash" is made usually when the front axle is raised, where the track rod is angled.
The force introduced via the track rod is divided into a horizontal force and a vertical force relieving the thrust member (1) against the spring (2).
The steering box is depressurized on account of no hydraulic assistance due to engine standstill and is thus not preloaded!
The play created in this way is incorrectly referred to as steering backlash.
