On my 95 Bonneville, the pulley clutch bearing is bad. It makes a very raspy noise while the compressor is off, but once the compressor turns on then the noise goes away. The A/C blows super cold!!! My friend said that its very easy to replace the pulley clutch bearing. I priced one out, and found it to be less than $10.00 for the bearing itself. Autozone rents the clutch puller. I was wondering how difficult this job is any if anyone had tempted this before.

Not yet..I have one waiting to do it though.

are u sure bearing is causing the noise . I had a noise coming from my ac also when ac off. It was the outer plate touching the ac drive pulley when off. It barely touched but would cause noise. There are 3 spring bars that pull it away. I pried the outer plate away from drive pulley near each of the spring bars giving it about a 1/16 " now between pulley and clutch drive plate. now no more noise and ac works fine.

Great idea, I will have to try this. Mine has been making noise with the compressor off also, sounds like a metallic rattle. I was hoping it would not need a new compressor... ;p

To check the compressor bearing remove the drive belt and spin the grooved compressor pulley.

Most compressors are ready to be replaced after 8 years any way.

My 90 bearing went out so it was not even drivable.
The under hood sticker showed a dotted line for bypassing the ac so I installed the shorter belt and ran it for about 2 yrs. This was a mistake as this shorter belt took out my water pump which jumped the belt and took out my crank sensor = stuck on side of road.
Spent a couple hrs at Auto Zone with their tools and the ac clutch wouldn't come off no way no how (PITA).
You have to get the clutch off first with an internal screw in puller, then remove the snap ring, then pull the pulley and bearing assembly.
Finally got P.O.ed and went to the Junk yard and got the whole compressor.
Even the garages I talked to said they don't touch them other than installing a rebuilt compressor.
In my opinion if I had to do it again and had the money I would just buy a rebuilt compressor.

A GOOD rebuilt can come with a warrenty of a year or more. I put one on (not on the bonne) 5 years ago and it'* still running strong.

I would also question the bearing. I know mine did that for a long time, had the clutch plates regapped and everything was silent again

Mine was definitley the bearing. Locked up and made that familier bearing noise while I could see clearance in the clutches.
