"THUMP" noise in trunk area when backuping up in my driveway?

Hi guys,

I noticed that when I'm backing up in my driveway (which is a hill) I hear a thump noise in the back area of the car? Almost sounds like some sort of shift or something? It only happends once right after I accelerate. Any ideas what this could be?
