Different issues: the rearend, mounts, and assocaited bushings are all about the clunk and whine... the GM and Specter bushings and/or spacers are about wheelhop.ahahnu said:Does anyone have the specter bushings? Do they remove the parade clunk? I haden't herd the noise since I had a new rear put in 350 miles ago, now I herd it backing up last night. I'm not too thrilled with the "fix" from caddy and wanted to know about performance, and price. Anyone that can assist, thanks in advance.
