Re: 156 driver wiper going off the window ???????
If you do as Gazza82 suggests and remove the cover you can check both the fixings and the pivots between the cranks and the links. The amount of movement you found does seem excessive providing this is without flexing the arms themselves. Anyway with the cover off you should be able to feel any movement, and therefore wear, in the parts. If replacing the complete linkage, make sure the motor is stopped in the "off" or parked position. The arms can damage the bodywork if they are assembled in the wrong position.
