What’s the issue?

I have a tone in the cab at certain speeds while decelerating. You can feel it in the door panels and floorboards. I have even had it do it at cold start idling down. I at first I thought it was rear gear noise but being in park at cold start up eliminates that. I was thinking the noise canceling thing but I rolled down windows this morning to eliminate that. Still did it. Its a very fast vibration with a deep tone. Reminds me of u joint vibration.
