Set the steering wheel to the middle position.
Through the open window, turn the steering wheel in different directions. In this case, let's say the play, measured on the steering wheel, is 25 mm.
If the play on the steering wheel is large, check the steering rods, the steering mechanism and the play of the front wheel bearings.
Strongly pull your hand on the steering rods in different directions. There must be no play in the ball joints, otherwise replace the ball joints or steering tips.
