So I got pqr500060 pulley but that's the pulley on the right side. I need the one for the left side bits a bit bigger the one I need.
Can I still install the smaller one? Tensioner will just be further down

 

Well I installed it and started up the motor. All well except the noise is still there. Wierd sounding too. What else could it be?

 

Do you have a stethoscope? You can listen to each pulley. There a number of things that cause a squeal when they fail and if we guess and are wrong... we just don't want to be guessing on your dime.

Spray grease on each one one at a time and figure out when the noise goes away.

 

Why are you installing non stock diameter pulleys?

 

It's not a pulley, or at least not a pulley bearing. When I spray the belt the noise goes away then comes back in a few seconds when the lube is gone. I also noticed the crank pulley has a slight wobble. I have a feeling that's causing the noise when the belt hits the outer edges of the purely it squeals.

 

I threw it on just to see if the noise would go away but it didn't. Stock back on. (I wanted to make sure that was the problem)

 

Change the belt.

 

Will do

 

I just had the same issue with with my dodge pickup, turned out to be a POS belt. After swapping the idler pulley, the tensioner pulley, and carefully investigating all the belt driven accessories, it still squealed (with brand new autozone belt). I shot some armorall on the belt and all went silent. I put a gates belt on and no more squeals..saved the squealer for emergency spare (in the truck). My cousin had the same issue with his Cherokee recently as well.

 

It's a dayco belt I think, doesn't look that old either. I'll get a new one tomorrow.
