Weird noise when decelerating

[AMGRAPTOR]

i’m getting a weird noise on deceleration from about 15 to 20 mph. Nothing has affected driving everything seems normal just wondering is this the front driveline or front hub bearing assembly? You can hear it best at the 9 or 10 second mark of the video.

Brakes rubbing? Rotors?

Not sure. I hear it only once the truck is warmed up. I guess I’ll have the dealer check it out.

100% the front drive shaft. I had the exact same thing, took a while to figure out, but that was the fix. I worked at the dealership, so my tech figured it out. Perfect after replacement.

Thanks for reply. How has it been since or were you the one that sold the truck after?

It was perfect, that happened at 300 miles and not the reason I sold it, it was the cam phasers at 900 that did me in LOL But being honest it took a long time to figure out, I live in a tree lined community and recorded the echo, and then finally drove my tech down my street as we could not duplicate at shop, then after the ride he figured it out and was able to duplicate at shop and replaced the front drive shaft and BOOM perfect!

I have some info to give the dealership now thanks to your reply. I’m at 6800 miles now and this and one side mirror camera going out has been only issues so far.

Are talking about that humming/whirring sound?

Yes

Did y'all notice extra tire/road noise first, or is that just the KO3s getting REALLY loud?

update- @danmoochie was correct. The front driveshaft shaft was replaced and the noise is gone.
one more detail I noticed was my 24 RR’s front driveshaft was all rusty straight from the factory and when I looked underneath a 25 RR they had at the dealership it was a clean looking steel piece and that is what they replaced mine with.

Fantastic. Glad it worked out.
