    I too have the whining sound coming from my alt. side. I figured it was the Tension pulleys so I got a new one from Autozone. I also replaced 3 pulleys and my S/C belt and all them came off easily.

    However when I tried to take off the Tension Pulley from the Accessory side, it wouldn't budge. I didn't want to force it in fear of breaking it off. Does it come off with a simple 13mm bolt like the others? I'm only asking to make sure I don't damage it.

    Thanks in advance!

    ok....noise is back with a vengeance...It is definitely the alternator...It appears to be the rear bearings...I am going to replace it with an OEM from a buddy who works at GM.

    Mine did the same thing! At first it was only there when the car got hot but after a while it started doing it constantly. I took the belt off and the alternator definately felt like the bearings where out.
