    All I was able to find was A/C compressor bolt and nuts 21 Ft.Lbs.
    Start with the front upper, next front lower, then lastly the rear bolt.
    These are the 2 stud/nuts and 1 bolt which hold the A/C compressor in place.

    There is a rear bolt?
    This is the one on The 4.0.
    I thought it only had 2.

    I can't speak from personal experience(3.7 here), but that is what the SM says for the 4.0. One at the top front of the compressor, second one at the bottom front, and a third bolt secures the rear of the compressor to the engine.
    Is it possible this is not an OEM compressor?
    It should be a Zexel DKS-17DS

    Humm I will have to look when I took it out once before it only had 2 but the dealership fixed the ac a long time ago. So u know how that goes... Probably did not put one back in.

    Yep, been there done that...

    In the 08+ years, Dodge changed over to using studs & nuts on the front 2 and a bolt on the rear. Probably because of your exact problem. As you know, steel and aluminum don't play well together over time.

    What I find strange about this is, the parts manuals don't show that bolt. But the SM does.
    To bad another 4.0 owner hasn't jumped in to verify it on their rig.

    If it is consistent with the other bolts, it should be Metric.
