2002 Honda Accord

I just recently taken my car to the honda dealer for a noise that I dont understand where its coming from I explain to them that Everytime I hit potholes or driving on bumpy roads I hear a rattling noise from under my car. The tech look at my shocks and struts and states that everything look find and there is no damage or any wear and tear so what can this noise be Sumtimes it feel like a ball dribbling when I go over a very bumpy road.
