I hear it. Is it only when you have pressure on the gas pedal? I had a similar noise that happened exactly at 80mph but disappeared as soon as I took pressure off the gas. Reappeared as soon as I touched the pedal again. Ended up getting a whole new rear end under warranty.
 
Was the rear diff chewed up or something?? Curious how many miles too?? 😕
I got the truck with around 10k miles on it and noticed it shortly thereafter. Got it replaced at 14k. The service advisor didn't give much info, just "must be a bearing or something".

I have video of my noise also, but can't figure out how to upload it. I don't have an account on any online video hosting platform.
 
Did your problem go away? I am @ 12000 miles and have same noise, dealer replaced the rear differential and it still is making same noise. Please if you could find out exactly what was replaced and if it solved the problem, thanks!!
Like you, they replaced the entire rear differential. The sound did go away after that.
