00 00... Steering components: Check for play, damage, tightness: Notes

Checking play: 

  1. Check the tie rod backlash only in loaded condition or in the design position.
  2. Checking with front axle raised:
    • To evaluate the play of the steering gear, it is necessary to pressurize the steering gear via its servo system!
    • The combustion engine must be running during hydraulically or electrically assisted steering for this purpose
