I find if you go around with a rubber mallet and rap on the frame and hard parts of the body and see if you can duplicate the noise(s) you hear driving. If you can duplicate the noise, then follow it to it's source and fix it. On my '85, swapping the old, worn rubber body mount bushings to polyurethane was a big help in cutting down on rattles from road bumps.
