Removable towing bracket: Ball joint

The spring mechanism inside the ball joint must be in the "ready" position.

– Check that the red marking 2 ⇒ fig. 238 on the knob is inside the green zone on the ball joint.
– Check that the locking ball 1 is inside the hole in the shaft section of the ball joint.
– Check that the knob protrudes visibly from the ball joint, so that there is a clear gap 3 between the knob and the ball joint.

The ball joint can only be installed if the internal spring mechanism is in the ready position.
