Brakes. I had a similar sound on my '00 INtrigue and after finding slop in one wheel, figured at 160 they were both worn, I replaced both hubs, it needed brake pads, found a CV joint cover ripped, new struts...dang, I really got into the thing. Was all proud until I drove it, still squeaked around right turns.
Result: Brake rotors had a slight lip on them, and the wheel bearings are good but there is a bit of deflection. You probably need them turned a LITTLE bit or new rotors. You might even be able to take a 4.5" grinder with a flap wheel sander pad and take the edge off if someone can rotate the hub for you while you hit it.
I'd bet that's what it is.
