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.

Solution:
1. Check the tie rod backlash only in loaded condition or in the design position.
2. Checking with front axle raised:
Desired state: The steering must be backlash-free in all components!
