2000 sedan deville drivers rear mystery rattle
 

rear shocks replaced, three mechanics (dealer) looked at it and said everything is tight. Does anyone have any idea? It sounds like a golf ball hitting, or a loose shock, but that's been eliminated. Any ideas, anyone? It is very annoying, and makes it sound like a rattl-ac, not a Cadillac

the trunk has been checked for objects, spare and jack is tight

raddles are tuff when your in, and have the car, let alone trying to figure from print. however, my last raddle was similar, and found an exhaust clamp bad.... hope it helps...... good luck
