I have almost same problem to yours. Mine is 94. The compressor makes noise and it looks like has problem with bearing. I would like change it.
Your post should be much useful for me.
I still have some question and hope you can give me some more details.
1. how did you remove the nut first?
2. after you remove the nut, you removed the pulley. Then, how to remove the clutch? Is the clutch just go with pulley?
3. Now I know there is a retaining ring inside, do you think there is any way to remove it before any broke?
4. Do you have any manul the show how to do it?

It came off VERY hard - because there is a retaining ring inside which is not visible or accessible - must be they do not want anyone taking this apart. The puller broke the internal hub where the retaining ring groove is, and the ring came
off along with the outer clutch hub and pulley. I got a new bearing from GM dealer at 40 dollars. Replaced the bearing in the pulley, removed left front wheel and inner fender liner so I could tap the new bearing/pulley in place, then tapped the outer clutch hub on (it has a key in it) and tightened down the nut - I added a lockwasher under the nut. Could not repair the internal hub where the retaining ring was - but the press fit and nut seem to hold the pulley & clutch on quite well. No vibration, no noise, and the AC works well. Thanks again for all the suggestions.
