What could be making this clattering sound! May 10, 2007, 12:56:06 PM Last summer, I swapped out the springs all around on my car. Used BBK lowering coils up front, stock '94 GT rears with overload airbags.Ever since the spring swap, I have this weird clattering noise coming from the rear suspension when I go over bumps at anything above 10-15 mph.The springs have polyurethane isolators top and bottom and are not loose in the spring cups. It's definitely not the exhaust hitting as it sounds like some sort of sheet metal clattering against something else. I looked all over back there and can't find anything.Any ideas? Quote Selected
