Remove the belt, start the jeep. See if noise is still there.

Try taking a paint marker and give a index point on the balancer then drive it. If it is the balancer starting to spin on the isolator you know.

Take the serpentine belt off and spin everything by hand. Assess whether you have any bad bearings.
