Hum from rear axle

I’m noticing a hum coming from the rear axle that starts around 74 mph and becomes very noticeable by 80 mph—especially when letting off the throttle, which makes me think its the pinion gears as riding the backside of the gears increases noise. The truck only has ~400 miles on it.

Has anyone else experienced something similar?

I know it’s under warranty—I’m calling the dealer tomorrow to set up an appointment. Just trying to see if others are running into rear axle issues. Every Ram I've had having the AAM 11.5" were flawless.

Update: First available apt 4/17. I'm sure its only going to get worse until then. Guess I'll wait to tow even after hitting 1k miles and getting a number of heat cycles on drivetrain. Don't want that being a way for them to deny warranty. At least I'm not getting the electrical and emission issues others are having (hope I didn't just jinx myself). LOL
