What is causing a rattle in the right rear of when driving over slightest bump

What is your question?

I am experiencing a dull rattle of sorts emanating from the right rear of the car when negotiating slightly rough terrain irrespective of speed.After checking for loose muffler components and finding no problem here, I feel convinced it's in the suspension such as a loose shock or other suspension joint.Can anyone provide a diagnosis?
