The noise COULD be your sway bar rubbing against the frame. Take the wheel off on the side where the noise is and look for shiny metal, which would indicate recent rubbing. There shouldn't be any shiny metal (Or shiny plastic either) in the wheelwell area.
If it is, then use a pry bar to force the sway bar back towards you about 1/2 to 1 inch (until it's centered) Be careful, that's hand cutting territory there too!
