Rumbling sound when driving

I do not hear it in neutral or at idle. It starts off sounding like a womp womp but as I accelerate it becomes a higher pitch rumbling sound. When I let off the gas it slows down but it's still there until I accelerate again. My tires are new less than 5000 miles my bearings are good. My transmission was serviced about eight or ten thousand miles ago. Any ideas what it could be?
 
We could literally name every piece of your drive train. Take a video. Narrow it down to a general area- Rear, middle, front, engine bay, etc.

The noise sounds like it is coming from behind underneath me. Kind of sounds like a cross between a vibrating motor mount and a chipped tooth in the rear end. I did recently notice that it can not be heard when i put it in reverse and back up. Any suggestions? Thank.
 
From what I can hear, it seems like it may be a resonant condition in the rear end causing undesirable vibration and audible feedback from non-synchronous frequencies generated in the spectral waveform of the rotating components.

Clear symptoms of a Taco Bell drive through meal. Did this start about 20 minutes after the last Double Cheesy Gordita Crunch?
