Default Which A/C pulley chirps?

My car has developed a chirp when I turn on the A/C. It's not the belt because I've already replaced that. I'm pretty sure it's a pulley that needs to be replaced, but I'm not sure which one. Which A/C related pulley is the usual culprit of this chirping? Pics of the pulley in question would be helpful.

If it is indeed the pulley your bearings could be drie. My 98 would chirp constantly and I ended up repacking all of my pulley bearing. It took less than an hour to do and made a huge difference.

repack the bearings on the pulley wheels, it's such an easy thing to do. I did mine and haven't had a chirp issue since.

My chirping was from the tensioner...it was pretty easy to tell just by looking at it. The chirping was exactly in time with the movement of the tensioner.

How exactly do I do this? Just use a pulley puller to remove the pulley and stuff the bearing area with grease?
