This 02 DHS has 102,000 miles. My wife mentioned that she heard at noise in the left rear tire area when going over rough pavement. After sitting in the back seat I realized she was not dreaming. It is a slight rattling noise that sounded at first like it might have been coming from something in the trunk. I eliminated that possibility but did notice that when pushing up and down on the left rear I can hear a noise that is sort of like rubbing. Does not happen on the right side. Could this possibly be related to the struts or is there something else I should be looking for?
