Has the car even been in an accident? If so it could be a bent frame (worse case), Otherwise the car could be off balance and needing an alignment (Most likely - best case) :)

ABS------ Anti Lock Brakes will cause a chatter if applied with a lot of weight pushing it. An E350 is a big rig.
Might ask your Ford Tech about that possibility.

Get a shop to read the codes from the engine computer. You can do it yourself by grounding a pin on the diagnostic connector and counting the flashes from the check engine light. The code will tell you which part is causing the problem- usually an oxygen sensor or an EGR problem on these engines.
