To me this sounds like one of the following:

-out-of-round tire
-detreading tire
-out-of-balance wheel
-bent driveshaft (which will also be also out-of-balance)
-bent stubaxle (2WD rear, or Syncro either end)

Any of these can cause a violent shake if bad enough, and the only noise
will be parts of the car bussing in harmony.
