Another thing you might try to do is see if you can or should snug up the drag link and tie rod ends a turn or two, also make sure the pitman arm bolt is tight and there is no play between your steering shaft and pitman arm. I'd recommend going through everything but since you are on the road and that is not possible my suggestions above are a good start. In the end the best course of action would be to rebuild all your steering arm and pitman arm balls back to round, new tie rod and drag link inserts and springs, and then go through the steering box.
