gonna have to say it's a balljoint or two.
stripping it down to the bj's is easy enough and you can get a good feel for them with nothing on there.
Not necessarily. You cannot say its the ball joint if it wiggles while holding at noon and 6. It could just as easily be the hub.
Best thing to do is have someone else wiggle the tire while you watch where the slop is being introduced. If its bad enough, it will be obvious.
Something else that can sometimes help diagnose a bad hub - try rotating the tire by hand and see if you feel or hear anything abnormal.
