Some other possibilities to consider are the rear tires (this would typically manifest itself as a shaking side to side in your belly as you go through the speed of greatest resonance)a bad wheel bearing or a rim that is bent. Although you can actually balance a bent rim it will still run side to side. A simple test is to raise the tire off the ground put a stick just touching the rim from the side at the area where the tire meets the rim and then to slowly rotate the wheel by hand and see if it moves in and out from the stick.Repeat for each tire. Another way would be if you could swap tires one at a time with another "D" that doesn't have a problem. When the vibration goes away you found the tire. Sometimes tires develop a hard spot and even with balancing they cause vibrations. Feel the sides of all tires, a ripple or bulge indicates internal damage.
