    Help identify noise... videos

    The "peeping" or, "chirping" or "squelching"??
    Only makes this noise when warmed up, and running low rpms. Until recently that has meat only when off road, in low range, crawling about. However, about 2 months ago I was idling around the neighborhoods looking for a friends lost dog, and it did it then too.
    Never does it daily driving.
    At first I thought is was my power steering box, but, when I went hydro assist that saw swapped out, so, cannot be 2 boxes in a row making this unique noise.
    Some say it's an accessory or idler pulley, but, is too inconsistent in my opinion, and, a shop looked at the pullies (belt off, spin/jiggle) and said they are fine.
    first video the noise starts pretty much from go.
    second video noise starts around 55seconds.

    Anyone ever dealt with this/know what it likely is?

    Sounds like the power steering pump is starving.

    If the reservoir or supply line isn't set up right, it's easy to starve the pump on a hydro setup...

    That said, I'm not sure that is what your noise is. What pump are you using? Pulley? How old is it? Also, what cooler setup and fluid are you using? These things may help get to a good diagnosis.

    If you would pry your sorry arse out the Scottsdale Fashion Square once in a while you would know more about the BLM and the USFS (you do know those acronyms, right?).

    I don't know the answers to your questions, but, it did the silly noises before, and after the hydro setup.
    Guess I could ask Ben(4whlrs) if they have documentation...
    I know the entire assembly/cooler was sourced from PSC, and, it's about 1.5 years old... with about 3000 miles on it.

    Use a stethoscope and check control valves, sounds like one is oscillating to much, like the old PVC valves use to.

    So, IAC valve?
    What other control valves are there?

    Fwiw-I've heard an IAC cause engine idle to fluctuate, but never heard it make that noise. It's always at low speed too, when it happens.

    Not familiar with the new JK's, there should be at least a valve for your charcoal canister purge.

    idle is rock steady, but, it only does it when it's up to operating temp's, and when I've be "idling" along... like, 1st gear 4lo crawling, or, just sitting for a while...
