Notes on checking steering backlash on
vehicles with rack-and-pinion steering (with
front axle raised)
Note:
When the front axle is raised, the applied force is distributed via
the tie rod into horizontal and vertical forces. If there is now no
electric or hydraulic assistance, the forces created cause the
thrust member (1) to be unloaded against the spring (2). The play
created in this way is incorrectly referred to as steering backlash.
3 = Rack
Important!
Target state: steering must be free from play in all the
mechanical components (except for steering gear and tie
rod)!
Note:
For checking purposes, the steering gear must be pressurized by
means of electric or hydraulic assistance.
