high pitch noise...video

well I replaced the serpentine belt and one of the idle pulleys to fix this noise but it is still there. Any ideas what it could be? The high pitch noise comes and goes, but only happens when I am maintaining speed. If I let of the gas real quick it goes away.

Take your serpentine belt off and spin all pullys. One of them is bad. Could be other idler, or alternator. Can you hear it at idle? If so get piece of wood or steel and move around to each part and put to your ear, you'll be able to hear what is bad. Did you get new belt adjusted tight enough?

Had one other thought. Get under your jeep and look over u-joints. Have had a couple get pretty loud. Just a thought. Good Luck
