Whining noise help

Hey everyone, I’m getting stumped over here and cannot identify this noise coming from my Tacoma. I did some searches and still nothing.

It’s Only happening while driving in D and is pretty consistent. I also was driving and threw the truck in neutral and cut the engine and the noise still happens while coasting. Doesn’t happen while idling or revving the engine. No problems with shifting the A/T and no slippage. Just changed fluid and level is fine. New hub assemblies put in a week ago and rear driveshaft unjoints and carrier bearing just replaced 6 months ago. I’m changing the serpentine belt tomorrow for the hell it but in my opinion that’s not it (maybe someone else thinks different). I posted a video with the noise. It’s a loud high pitch whining. I’m chasing a noise at this point and any input would be awesome. Thanks!

*i tried to upload a video with the noise but it’s not working* I’ll see if I can post it to YouTube and put the link on here.
