If you still have the vibration with the car in neutral, then it is not related to engine RPM. My guess is that it is probably a tire. I would have the tire balancing checked before I started replacing anything.
I am thinking that bad u-joints would show up as more of a clunk when loading/unloading the drivetrain, and not just a vibration.

I had a front tire start to delaminate causing just what you are describing. Have your preferred tire shop pull all four and take a look.
I could also feel a waver through the steering wheel at slow speeds. But that wouldn't be felt if it's a rear tire.
