2012 V6 convertible. I hear a clunking noise when going over even small bumps. Noise is from rear suspension. Can't hear it with top open, but pretty loud when top is closed. We've put it on a lift and banged and shook every part and can't find anything that seems to be loose. When on the ground we pushed down on each side of the car and can't find a noise. Kind of lost on this one. The only possibility I can think of is a damaged shock that is making noise internally. Anyone think of anything else to look for?
