Set the steering wheel to the middle position.
Move the steering wheel back and forth through the open window. The steering wheel must have no more than 25 mm play on the outer circumference until the wheels begin to move.
With more play on the steering wheel, you need to check the tie rods, the steering mechanism and the play in the front axle supports.
Strongly move the steering rods back and forth with your hand. There must be no play in the ball joints, otherwise the joints or tie rods must be replaced.
