6.4l Chirp/Squeal [WITH VIDEO]

[TwinTurbo6.4]

Got a weird chirp/squeal. Can't seem to pinpoint it out. Any help would be appreciated. Just had the alternators replaced about a month and a half ago. Belt tensioner doesn't look pulled away like i've seen those issues. I do notice the camshaft pulley is wobbling. I'm guessing it's also the harmonic balancer. I do have dual alternators if that matters. Seems to be heard most at the front of the vehicle.

I would start by checking belts... spray a bit of water on em to see if it goes away. If it does, it's a belt issue. Start simple, right?

I actually picked up a spray bottle during lunch. I wanted to, but didn't have one. Haha.

Check up-pipes and look for any broken exhaust manifold bolts.
I had a broken exhaust manifold bolt and sounded like I had a bird stuck under my hood.
