**Need Feedback Please**
I have this annoying squeal and squeek sound when the motor is cold. The sound goes away after warming up.. I've changed the tensioner, tensioner pulley, idler pulley, alternator (I was going to change anyhow), and belts.. I put a gatorback belt on... The sound went away for about 2 weeks but now it's back even louder.. The harmonic balancer does not have a crazy wobble.. The balancer have a very slight wobble after staring at it for awhile but a slight wobble. Thoughts, feedback, experiences?

sounds like the elastomer rubber between inner and outer hub of hb has delaminated.look at it with engine not running.the front face of inner,outer and elastomer should be near level with a straight edge when you check it.look at the outer hub to make sure it has not moved forward or backward on the inner hub.some times you may not be able to see any obvious issue but can hear it when running.do not use a GM replacement hb or you may have to redo in a short period of time.if the elastomer is protruding from the hubs or sucked into the hubs there's your problem

I actually removed the serpentine belt to test and the sound is still there. It would have to be the ac belt then, right? I just changed it about 4 months ago. It wasn't making sounds then, I just changed it for maintenance purposes. Thoughts?
