For those interested to know I had two sway link kits (left and right) installed replacing the older ones. Only the left side was broken. Together both costs $46 for the pair. To have them installed they costs one hour of service resulting in 75 dollars of labor. I have not yet been able to repeat the driving conditions that caused the clunking sound mentioned earlier i.e.: a fully loaded car. Will probably have to wait for the weekend for that test. Will post results here which I am hoping will be noise eliminated.
