Why does my car make a clunking sound?
Mechanics at two different shops say that beyond the parts already replaced, nothing more can be done. Is their comment that “old cars make noises” true?Q.
My 1999 Solara has 120,000 miles on it, and it makes a clunking sound in the rear when going over bumps. The car has been well maintained, and the engine, transmission, and body are in great shape. The noise, while noticeable at normal highway speed, is most audible while I’m driving at low speeds. Adding extra weight in the trunk does not improve it. The trunk contents, including the spare tire and jack, are secure. All four tires are in good condition, and the struts on all four wheels have been replaced with aftermarket kits. The rear sway bar bushings have also been replaced. Mechanics at two different shops can hear the sound but cannot identify the source. Both shops say that beyond the parts already replaced, nothing more can be done. However, their comment that “old cars make noises” does not satisfy me. Due to the age of the car, is it reasonable to have all the rubber bushings in the rear replaced even though they do not appear to be loose or compressed?
A. As vehicles age, it isn’t unusual for the suspension and body mount bushing to dry out and get nosier. Your vehicle is 19 years old, so you may find that some of these bushings may be hard to find. A technician needs to carefully inspect all the bushing to determine if old age has caught up with the car. The technicians’ comment that old cars make noise is true, but that doesn’t mean your car can’t be repaired.
