    I have narrowed it down to the exhaust. When i push up on this rubber hanger the noise stops. Now on to whether its the hanger or something else.

    Try spraying the rubber hanger with some wd-40 and see if it quits.

    Old thread but I have the same issue. Mine is exhaust related and at the same area. It is not the belt or an alternator even though it seems to happen when electrical things are turned on such as brake lights, headlights etc. Advance auto scan tool will tell you that it reads low voltage but it is normal for the 3rd gen 2.7 alternator which costs $500. That is a rabbit hole you want to avoid. It's the exhaust. Hope this helps someone in the future with this incredibly hard to find issue.
