I recently bought a 97 eclipse and it has been somewhat of an Lime (not in serious distress but certainty not what I thought.) Recently I have been hearing a type of gyrating noise along with a scrapping (metal against metal)( Usually dose it when accelerating /Decelerating ) noise that comes from the rear of the car and it is getting really irritating. No knocking or any actual gyrating in the car ,just sounds like it. any ideas?
