I have a 03 LS with 72K. It has the "clunking" in the front end.... so is it the sway bar bushings? Which was supposed to be the new design or the ball joints? It also has a vibration at 70mph and up. Brand new Cooper CS4's took a lot of the vibration out but it still has some..... they did mention both of the rear wheels are bent.... could the vibration be from the wheels or the ball joints which could also explain the clunking.
