Help identify a noise

[BrunoPizz97]

Getting this whirl sound in all gears when I drive. Don’t know where it’s coming from. Put my transfer case in neutral because I thought it maybe a failing transmission and the sound is not there. Put it in 2H, 4H, 4L and the sound is back. I also changed the trans fluid thinking I may be low, it wasn’t low but changed it anyways. When I let off the gas it’s loud when I’m on the gas it’s there but not as loud as when I’m off the gas. Putting in the clutch does not make a difference. I have a front diff locker and I’m not sure if that’s the culprit. I included 2 videos for reference... please HELP.

Need to determine if the noise is coming from the front or rear....
Could be a front axle hub bearing or rear axle bearing.....

Sound like it’s coming from the front. Would you believe it’s the transmission or no judging by the sound of the trans in gear while transfer case is in neutral?

IF you are hearing this noise when the transfercase is in neutral meaning the Jeep is stationary then the problem is elsewhere.

im hearing the problem when the car is moving at speed. No noise when transferase is in neutral and in gear.

Then I refer back to what I posted about the bearings.

So last night me and my trustee mechanic got underneath the jeep and tried diagnosing what it may be. So we ran the car on the lift trying to track down this noise. Running the car in 3rd and turning it off because my exhaust is loud and cant hear much when all you have is a resonator. We ran it on all drives (2L,4H,4L) the sound was persistent and did not change. We figured it was either in the diff or my transfer case. First we took a look at my rear diff, popped off the cover and inspected it. There was some metal flakes but def not chunks, the fluid looked gold with some black in it (I changed the fluid last summer). He inspected my pinion and had said that there is definitely play in the pinion, but not 100% on that being out main issue. We inspected my drive shafts font and rear they looked to be good with no play. He did mention that my transfer case did feel a bit hot, I may have a failing pump in there and its not providing proper lubrication. (but we didn't pop off the cover on that) we inspected my wheels and found play on the passenger side wheel bearing, so we changed it anyways. Buttoned that up and drove in FWD to see if the issue is in the front, No sound. Went back put on the rear drive shaft and then the noise came back. So the 2 things that we believe is either something in the transfer case or its my pinion going out.

My hearing is shit and it's through the inTRAnet but I don't hear a bearing issue...

I pick up a sound of....it almost sounds like two gears or (teeth)that aren't engage with each other but are close enough they are skipping off one another buy not fully engaged.
