Were the tires on there long enough to show any unusual wear?

I am thinking tie rod ends or idler arm, if you have indeed ruled out tires and wheels. Other possibilities include warped front rotor with sticky caliper. Of course there's always the flex joints.

Can you be more specific about the shimmy, what speeds it shows up at, and how you feel it?
