Well I checked my alignment and it is very close caster +2.5 degrees, camber +1 , 1/4" toe-in (as acuate as I can check on my unlevel garage floor) I don't think it is far enough out to cause a problem. There is very little play in the king pins, and tie rods but it doesn't look like enough to cause a problem. I'm not sure what I am missing. It does seem to be worse if you hit a bump, like loose parts but I can't see any thing. I hope you have more ideas.
