This is starting to irritate me. I drove to an airshow a month a go and they made everyone park in a field. There was a big dip in the dirt road that was bigger then I thought and took it a little to fast and having 3 people in the car I bottomed out bad and heard a nice metal clunk sound. Ever since that day if I go over a small bump I will hear clunk clunk coming from what seems like the back passenger side. Sometimes I will hear a rattle other times it’s a clunk. It doesn't do it all the time so its tuff to figure out where it’s coming from. I try pushing down on the back of the car but don't hear the sound. IV looked underneath to see if my exhaust is tight and everything looks and seems good. I'm going to go back out tonight after my car cools down and have a look again. What do you guys think is making the rattling and clunking sounds?
