Squeak when accelerating

[smashweights]

I've noticed the last few weeks when driving without music and the windows down I can hear a faint, high pitched squeek coming from outside the truck. I managed to figure it's when I hit the accelerator even lightly. It will make the same noise even when hitting the accelerator while in park. The best I can describe the sound is like a brake squeal but quieter.

Any ideas?

Belt slipping?

That would just cause a steady noise following the speed of the vehicle.

Caught a video of it for you. Truck is warm and idling after going for a drive here.

and start listening to different areas.

Sounds like an accessory drive bearing or water pump squealing. Stethoscope time, I have something like this.
