My 54 3/4 ton is wandering pretty bad. It really does not seem to have play in the wheel and it doesn't wander all that much at low speeds, but the faster i go the worse it gets. at about 50mpgh it about takes everything i've got just to keep it between the lines. would it be tie rod ends, king pins, etc. or would it be steering box adjustment, bearings, etc? I know nothing about steering gear boxes. I read the tech tip on adjusting it and don't know what i'm looking at. Any help would be appreciated.
