Explain the vibration.  WHat RPM and MPH does it occur at?  Does it vibrate when sitting still and in neutral?

I call out of balance driveshaft! Or, a bent axle. Mine doesn't shake until about 80, I suspect the transmission/torque converter of not liking that RPM.

Wheel balance, bent wheel, bent axle, out of balance or bent drive shaft. Those are the usual cause of vibration.

It doesn't vibrate when you rev it sitting in park does it? If so then you have an engine issue.
