Squeaky noise
 

Hi there. Just recently, after some rain, I noticed that my 05 chrysler touring was making a very loud squeaky noise. I popped the hood and it looked like the noise was coming from the a/c compressor pulley. Im thinking it needs to be replaced. Does anyone have a manual, or suggestions on how to replace it? The part im ordering is called the a/c compressor pulley hub kit.

Thanks
