Can someone please help to identify the whining noise heard in this video? It's follows engine speed

No one? It's quite annoying in person and I just can't figure it out!

I cant hear it. But does it do it while in Park and revving the engine? If so, then its not drive-train related. Just trying to help a little if I can. Sucking in air, from places like the air-box foam missing can cause a whining. Other causes while in Park could be belt tension pulley, alternator pulley bearings, idler pulley bearings etc. Or it could be a worn serpentine belt. If it does it only on acceleration, then wheels bearings, IWE's if you are 4x4, rear diff gears etc.

I watched the video 3 times. The sound is not clear enough. Try posting a video from the outside and have someone gently revving the engine in park like Summers said.

Ill give that a shot and try to post again for better sound ... It does do it in park, so it's not drive train, just can't figure out if its engine or pulley system somewhere. Belt was replaced 1.5 years ago with Goodyear gator back I believe it was. No pulleys or anything else has been replaced to my knowledge, but all seem to spin freely and noise free with belt off.

Sounds power steering related to me.

Has it always done it since the belt has been replaced? I put on a gaterback a few months ago and it sounded like I had a supercharger. The noise has since disappeared. I know I've read these belts are notorious for it.

I don't think that is the problem because it follows RPM's

I tried swapping out the gatorback and no dice. I still need to get a better video of the noise, but I may be trading it in this week so we will see. Those 2015+ just look too nice to not have one! haha
