2011 Volkswagen Jetta Sedan


I recently purchased shocks for the rear and installed them. Now every time i hit a bump there is a rattling noise coming from the rear. I checked and everything is torqued. According to the Monroe site, it called for part number 5528. Any idea what the noise might be? I put new struts on too and after ordering struts for the sedan, it actually needed the part number for the wagon after talking to tech at Monroe. Any help would be appreciated.
