View Full Version : Trouble with infiniti I30?

09-06-2008, 04:41 PM
When I drive over bumps, there is this shaky clanking sound which I figured out is coming from something that lies directly under that bump on the floor of the back seat. My car hasn't felt different when I've driven it, and it's only over about half of the bumps I drive over. It's been going on for about 2 weeks. What could this be??

Probably your muffler or exhaust pipe is hitting against something - a fairly common problem. Perhaps a hanger is broken or bent / displaced. If you can, reach under and shake the exhaust system components horizontally & vertically and look for a hitting situation.
