The steering box needs to be centered so it steers without slop. The boxes have slop when off center. I would get the box centered so it is tight and then figure out what to change. You should be able to find or make an adjustable drag link to fix the problem. Is everything a modified system? Has the shaft been welded on? It may need to be redone to center the wheel. The keyed shafts have a specific orintation so the wheel will be centered.
