Really odd sound... Any ideas? (Video)

[AEsco48]

Hello.
Was driving back yesterday from Keystone back into Denver and on the highway, on multiple occasions, I heard a like rumble sound as well as feeling, felt like it was coming from under the Jeep. Though it was the road, switched lanes, still happened. Happened a few more times, still felt like it was the surface of the road. Stopped, looked under the Jeep (2021 Gladiator Rubicon Diesel), nothing looked out of place.

Got into the city and it happened 3 times, omn the 2nd i pulled out my phone and started video recording.
I put the car into neutral while still driving to rule out the engine/load, no effect, speed dropped and the sound persisted until just before I stopped.... I pulled over (you can hear the turn signals) into a gas station to look around again.

Last night I took out my crawler and got under the Jeep and dont see any lose suspension joins/components, areas where there is movement between components that should be fixed together...

Any ideas?

Jeep has a Warn winch on the steel bumper, a Rhino rack with a snowboard carrier (sound was coming from below me). Suspension is stock.

If I'm hearing correctly it seems to change in pitch with rolling speed?

Yes, at the end. But its a minor change and even at highway speed it was not much different... i think.

And no sound when stationary, regardless of engine speed?

Video didn’t play for me. How many miles are on the vehicle? Have you considered the driveshaft?

Inner fender liner contacting the tire?

FAD(front axle delete) failing. Try shifting into 4wd when it happens, if it goes away then it for sure is the FAD. It just started on mine a couple weeks ago. I have a 21 JTRD too. Kinda pissed about it as I haven’t even really abused this thing like I plan to.
