Ohh no doubt im not saying to Not rule out it being something belt driven at all

Cover all the bases for sure

I just took the belt off mine and the sound was still there. Now I've somewhat narrowed it down to the rear driver's side of the engine compartment and I'm checking all the vacuum lines to see if there is a crack in one that could be causing it.

Does the throttle body have a spacer installed?

Listened to the audio. My daughter heard it and stated that you "obviously" have a spooky ooky ghost in your motor.

Ya. She's 19. I dunno bout that. I think that it sounds like a throttle body spacer or a gap/missing gasket whistle.

Have the belt off. I get paranoid when doing stuff like this (removing something and starting the jeep when something is missing). But I don't have to tighten the ps back down until I put the belt back on right? It won't hurt anything to start it with the power steering pump loose since it won't work because the belt's off right?

Here is what mine sounds like and if you listen close you can even hear the alt bearings making noise aswell

Well Gage you spoke from experience! Here's what I did:

1. Took the belt off
2. Started and listened. (OMG how I miss that deep purr over the spooky ooky ghost)
3. Turned the alt pulley by hand and boy was she rough.
4. Sprayed some WD-40 on the pulley.
5. Reinstalled the belt.
6. Started it back u and she purred then about 30 sec later the ghost came back, WD-40, 30 sec, WD-40, 30 sec.

SO I am gonna order an alternator (code DOW37 for Advance Auto gets you 35% off orders of $50 or more! SWEET!).
Thanks again everyone for the thoughts and input. So Luuca you can tell your daughter I will be getting rid of the spooky ooky ghost

Hey Dusty you might want to look at putting in a Grand Cherokee alternator. The price is close but it buts out almost 40 more amps.

What exactly does that swap entail? Is it a bolt in and wire up or is it gonna require special mods? I will search when I get off of work.

Rig up some sort of timed servo that automatically sprays WD40 on the alternator every 30 seconds.

I used to have a high pitched whine when on the trail. Thought maybe transfer case in low range but not so. Threw the wife out and the whining went away.

Niiiiice. So I did a little digging and correct me if I'm wrong but the ZJ-YJ alternator conversion is simply the 90 amp with a 136 amp? Some people have had to grind away at the bracket and/or swap the wires out with better gause and/or run a fuse to the battery. While some others have just plugged it in and gone with it?
