So far I have replaced the idler tensioner pulley bearing, A/C compressor pulley bearing and power steering pulley bearing and still makes a noise. The sound is definitely coming from the right side of the engine.

The serpentine belt has less than 20K miles on it and it's OEM.

Whatever this noise is, is causing my harmonic balancer pulley to separate and fail. I've had 2 harmonic balancers fail on me in the past month.

Get a stethoscope or a piece of a hose and identify where its coming from easiest way to do it.

Hey may not help and sound a little odd, but years ago on an old chevelle I replaced a PS pump three times trying to locate a noise like you describe. Had an old mechanic suggest putting a bar of soap on the business side of a pretty new fan belt while it was running....the noise stopped immediately. i replaced the belt and all went well. Now a question for you...Where exactly did you buy the Tensioner pulley bearing, I think my is going bad??

Turned out to be the power steering pump. Must of been something internal.
