I had the same rear end noise...disconnected the sway bar links to see if that was it and sure nuff it was. Question, how the the links work? I don't see how they provide ANY support since they're made of plastic with ball joints. The bar iteslf bends a lot...I just don't see any need for them. I temporarily have them off becasue the noise was driving me crazy. I intend to put new ones back on as soon as they come in. Please inform me if I'm making a mistake having them off. Thank you in advance for your help.
