I had the same issue, I replaced the belt, still chirped. I replaced all the easy pulleys, chirp remained. One day I was messing around and squirted some water on the belt, the chirp went away...So figured it wasn't a bearing or anything, so I pulled the belt and used my drill with a wire wheel and cleaned all the pulleys really well, thinking there might be some type of liquid or something in the grooves. Chirp went away ![Smile](https://blazerforum.com/forum/images/smilies/smile.gif)
So try that and see if it helps, spraying the belt with a bit of water and listening to see if the chirp goes away can help tell if it's the bearings or not. Good luck!

I have never bought a Gator belt but I have found the high quality belts much less likely to squeak, but if they do, I have sprayed AmorAll on the belt while running and usually after a few treatments the problem goes away. Works fairly well on the cheaper belts also but doesn't last for a long time normally. Been through 1 Suburban, two Jimmy's and an S-10 with this in the last 15 years.

My 89 S15 Jimmy belt squeaked for thousands of agravating miles. I tried lubricating the belt, replaced the belt tensionor, idler pulley checked the alignment of the power steering pulley and anything else I could think of to no avail. I finally tried the Goodyear Gatorback belt and that corrected my belt squeak. I became a believer. It has been quite a few thousand of miles with no belt squeak. My Jimmy has almost 450,000 and and is still my daily driver.

I finally fixed this problem on mine today!
A big Thank you to dryden3 and SuperG for the suggestions on adjusting the PS pulley. I pulled mine about 1/8 of an inch out.
I honestly couldn't think of why this would work because the noise seemed to be coming from the top idler pulley but it worked. No more noise!
I wish I had tried this before I replaced all three pulleys, the belt (twice) and rebuilt the alternator with new bearings.
I hope this post will someone else in the future.
