Help!! High pitch squeal/vibration during acceleration

Guys,
Please help before I lose my f***ing mind!!
So the other day I was hauling my boat and while doing 0-25 I’m getting this vibration almost like I’m dragging my trailer on flats or the engine is hesitating but than it smooths out and I start hearing this squealing noise accompanied with it. Now that my boat is unhitched I’m no longer getting that vibration but the noise still continues but at random and only while doing 0-40 and typically while giving it gas. Could this be a U joint???
I’m seriously at wits end and I can hear this noise in my sleep!!!!

 

Could it be the idler pulley or any of the others on te front of the ending holding the belt.

 

I’m trying to figure out how to post a video but I’m having trouble doing it

 

U-joints will chirp when dry and under load. Grease them and see if it calms down. They came dry from the factory.

 

Need to upload to YouTube and then post link here

 

hard to hear but it goes on for about 6 seconds.

You are right, difficult to hear.
If it happens when going 0, sitting still.... I am leaning to one of the pulleys on the front with serpentine belt

 

I can’t duplicate it while standing still. Only seems to do it while in gear
