So I am getting a clicking/clunk from my driver's side in the rear. I can't figure out what it is. It only is happening when the wheel is spinning freely (when I am accelerating, or using the brakes it is nonexistent). Do you guys have any idea what this could be? I need to figure this out asap.

 

year and model may help you get faster replies.

 

I don't even have an s type, it's an '02 lincoln ls. Because of the similarities between the two, and because I post here more often, I decided to post here instead.

 

Likely the brakes. Check the calipers and pads.
