Harmonic Balancer chirp?
noticed a chirp when i rev the motor today. I had laying around a tensioner, idler and gatorback belt. No improvement and while the belt was off the sound was gone. I listened to the P/s pump and waterpump and both sounded fine. you have to really tap the pedal quick and hard for it to chirp. I'm guessing its probably time anyways for my HB to go, car has 95k on it.
heres a video of it
does this sound about right for the HB to be starting to fail. There isn't any apparent wobble. and the belt is tracking straight.
thanks

With the serpentine belt off the noise is not present. I felt all the pulleys again and the only one that felt sketchy was the power steering pulley. Jerking it back and forth it clicks and it has play forward and back, my power steering has also seemed intermittently weak and one day over 80mph going into a turn it completely cut out for a moment. Im thinking its the culprit.
Not hard to change so i will probably change it in a couple day
Im just terrified the balancer could fail and it looks like a real pita to replace. I did mark the balancer in a few places and it does not appear to be moving

I replaced my balancer last year (2013). It was too difficult, but by the same token, I've done many jobs that were a lot easier. It's more of a take your time, and be careful job. I'm retired, so I don't need to rush through things, in order to get the car back on the road, so I can get to work, so I went carefully, and it took a little over two easy days. I also installed the ATI pin kit on the crank, and replaced the timing chain, while I was into it that far, so that did add extra time.......probably a lot more time then I realized!

Don't overlook wire brushing the HB grooves, all the way round. It's something easy to overlook, mainly because the grooves always seem to "look" clean. Grit, dirt, etc can change the way the belt rides in those grooves.
