I had just posted that I had gone to the dealer for an oil change and to fix the clunking sound [front drivers side] when I drive on a rough surface..he said that he tightened up the strut. When I drove away I did my best to hit every possible road surface to test out his fix. The sound was gone all day. Then that night...the clunk came back. Soooo I will be back again on Saturday morning..sigh.
