Difficult to imagine what could cause a speed-related vibration that is
faster that wheel-wobble vibration. Implies something is going round faster
than the wheels, which could be the prop-shaft. A regular vibration like
that should be easy to separate from something like a surface-induced
vibration, and a seized damper should be even easier to determine, simply
press down on each corner of the car and see if it moves or not.
