The more common parts to wear are the tie rod ends and ball joints. Unbalanced driveshafts and harmonic balancers are rare. I'd start with the front area first. You could also have an unbalanced tire, or if it is wearing unevenly and cupping, it can start a vibration at a certain speed. So I'd check tires, tie rod ends, and ball joints first for wear and looseness, then go to the other items.
