Are you able at all to identify where the sound is coming from? The E350's were notorious for wearing out front end suspension components, and can produce some alarming clunking sounds as you describe. Have you, or can you, have anybody take a look at the front steering and suspension and see if that might be some of the cause of your issue? It might be hard to notice if you aren't otherwise used to driving a bus or big van, but you may be able to feel some looseness in the steering wheel as you go over bumps as well.
