I'll take a stab at it, and would suggest lower ball joint.

Keep looking...eyeball anything that moves, or looks like it could move, closely. Try and to make it move yourself if you can, and listen for any noise, and look for excessive movement (compare amount of movement to the same part on the other side of the car, or better yet, to the same part that you know is good on another car)

Good luck with your search....and be careful!

BTW, for piece of mind...check the calipers while you're at it.
