It certainly seems to me that the drag link is too long on the adjustment. I suggest that you adjust the drag link so that the pitman arm is at the centre of its travel and as others have said, check that the pitman arm is fitted in the correct position. It should point straight forward with the steering box in the centre of its rotation. Disconnect the drag link, rotate the steering wheel from end to end then find the centre position, you should then see if the pitman arm points straight forward. If not then the pitman arm is not fitted correctly and needs to be resolved first, then adjust the drag link so the wheels are straight forward with the steering centred.
