You need to make sure the steering box is centered.
disconnect the drag link and turn the steering wheel full right and count the turns to full left go back 1/2 way and that is were you wheels need to be straight. Adjust the drag link to make this happen.
If the box is off center then you will have a lot of play in the wheel.
