Default 04 Chevy Suburban 2WD

I知 having an issue with my 04 suburban. When I知 driving around 40 to 70 mph and let go of the gas I hear a whining Grindy noise from the bottom. I did service on the rear diff and u joints and the problem is not resolved. When I accelerate the noise goes away. Any help is greatly appreciated thanks!
If I can get a video of the sound later I will post.

Check your wheel bearings. How many miles on it?

The noise is grindy and humming. Will do only on when releasing the gas pedal. Happened after I got some used tires for it too.

bad pinion bearing?
whatever it is, it's serious. I wouldn't be driving it too much.
