I recently bought a 2015 Ford Edge. It makes a squeaking noise (not crazy loud but noticeable, and not the same kinda squeak as a worn out belt) when driving, the wheel shakes when doing 55+ miles, and the brakes vibrate. The squeaking stops when I hit the brakes and turn, but they do still vibrate. We took it to a mechanic, they took the brakes apart, did some work on the rotors, balanced the tires, did an alignment and stated the rest of the brakes were fine. After all that work nothing has changed and every time we take it to a mechanic they tell us they can't find a problem, but they can hear the noise were talking about… Is there anything non brake related that could be causing this noise and shaking?
