i installed a special rear sway bar for my 2003 intrepid se and i keep on noticing that it makes quite few noise on the sharp turns and bumps. took a look under and the nut that connects to the bar and swar bay link was missing. so i bought another nut and tighten it up . more noise coming from the left rear tired. went under and see the nut there. a week later the nut is gone. i tighten up the bolt to my own max and its always the same nut missing. any suggestion. i already lost two nuts. dont want to lose another.
