probably the rear, or it could be the center support bearing, or it could be in the trans, I would have to check it out for myself to be sure..

does it sound like a belt? could be a bad pully...

If it is not a cracked or heat damaged belt, then yes, it could be a bad tensioner or idler. Fire up the car and see if you can isolate the noise. Spray a little WD-40 on the tensioner or idler bolt and see if it goes away. Then replace that part. Try to avoid spraying WD-40 on the belt.

trying to diagnose sounds without the car present is next to impossible. Try to get the car to someone to get a better idea, or else you will just be throwing parts at the wrong problem.
