My passenger side front wheel wobbles slightly on my 00 Ford Windstar. Wheel was checked and is bolted properly.

I would swap front and rear wheels and see if the wobble follows the wheel. Cast wheels should have almost no distortion in them....if they do, they've been damaged .....and replacement is the only solution.

First ensure it's the wheel and not the hub. If it's not the hub, it could be either a tie rod that needs to be lubed or replaced or worn out brake pads.
