Re: Clunky Rattle??
you installed CC plates, so that should have eliminated the strut-mounts (a likely culprit). The next likely source is the sway bar end-links. If they are not torqued correctly, they will rattle and make the noise you are describing. They are also known to come loose after they have been taken apart. If your panhard bar has steel ends, then they too will make noise going over bumps.
