Everytime I hit a area of several small bumps I hear a rattling in rear driver side area. When I am driving I never hear it. A large single bump never hear it. When it looks like a wash board area I hear a rattling sounds like it is coming from driver side rear area.

Even though it sounds on the drivers side, check the heat shield above the exaust system. They are riveted on and sometimes they break loose. There is also a shield above the gas tank which is on the drivers side and that could be loose.
