Hard to understand whats going on.  Any chance of posting a vid so we can get a better look.  Show us the tensioners and the air con compressor.  Just out of curiousity is there any difference when you turn the air con on?

Yes it definitely is a pain to change, I'm afraid.  What was the difference when turned on?  Did the noise go away?

The aircon pulley should spin freely since it operates on a electrical clutch to engage the pulley to the compressor only when you switch on the AC.

so the fact that its not spinning freeley means?

I can't get the pulley off to look at because when i turn the nut with a ratchet the outer plate just spins and the pulley stays still and the nut spins with the plate  :-/
