about 3 months into my 04 3.0 6spd and i have a random light clunk from the rear. not consistent, but usually when turning into a driveway at low speed and the pavement angles change. the car had mostly new suspension parts installed prior to my ownership including struts. subframe and diff bushing look OK. what i notice is the rear springs appear to be, not sitting on the lower perch square. is this a possibility? Could they be installed wrong or upside down? The picture is the passenger side, not a great photo but you can see where it looks off-set to the pad on the lower perch.
