I have a 2004 G.caravan with a front end shimmy. At first it was noticble between the 40-50mph range.Now it is getting worse and can feel it at lower speeds but only on accelertion. Let of the trottle and it goes away. I have had the tires balanced and have rotated them front to the back. All have good pressures. I have inspected the front end becuase after invesigating online i have heard allot about the cv shafts. They are not making any noise weather forward or reverse with the wheels cranked to the left and right. The cv boots are in good condition with no rips or tears. Is it possible that they are the problem?

The most common is the drive axles, tires, or motor mounts.
