Loud humming from 5.7

First time post guys!

I have just purchased this 2017 TRD Pro and must’ve been so enamored when I pulled out of the dealership that I didn’t notice.

there’s a loud humming sound and when I use an auto-stethoscope I can here it pronounced throughout the not any pullies from what I can tell.

any thoughts?

Will upload video

 

Not much to go off. First thought would be alternator. It's not a tick right?

 

Loud humming when? When you first start? When you park it?

 

Need more info. Does it happen only when moving or also stationary?

 

Wheel bearings?

 

Sorry guys… no tick

Changes when revving, seems to be louder when standing in front of front wheel wells, also loud from a distance. You can pick out the him frequency which is mid range. Happens constantly.

BIL texted a Toyota tech and he brought up water pump

I’ve researched for a day now when I can and haven’t found a “common problem”
