I have a 2005 honda accord EX V6. I get this strange clicking noise whenever I hit a bump. It is come from the rear passenger side inside the cabin. I have removed several of the interior panels trying to locate the noise. It is in the vicinity of the rear side curtain airbag infaltion unit. It isnt normal cabin noise like a loose panel or something rubbing. It is a distinct clicking noise. It sounds similar to the ball that rolls around inside a spray paint can if you flipped it over one time. It is the only noise and it drives me nuts but I cannot find where it is coming from. Is it possible the air bag inflation cylinder has something inside it that can make the noise?
