clunking growling rattling noises,no one seems to know why after struts, mounts bushings etc were replaced. does not do it with hi-way driving
suspect alignment problems with the alternator belt tensioner pulley. The outside of the belt shows signs of wear,and rubber residue on pulley and there is a vibrating noise or growling at low speeds when starting out from a stop. The noise goes away when the surpentine belt is removed. No solution yet
