AC clutch assembly sold as 1 piece, need a clutch or pulley
So I need a little help finding correct part numbers.
My AC whines at medium throttle in mid rpms. Doesn't squeek and doesn't grind, that bearing whine is the best way I can describe it. Sound can't be replicated at low throttle or wot and only happens with the air on.
So pretty sure it's the clutch or it needs to be backed out slightly or replaced. The part diagrams I've seen show the compressor and clutch assembly. Any past car diagram showed all the components from the clutch to snap ring, pulley, snap ring, coil with a plug than a bolt attached to the compressor. So is this like one solid clutch unit from Nissan where it's a one piece design.
Reason I want to know now if it's all one piece since determining if it's the clutch, vs bearing vs pulley is irrelevant if I have to order the same thing. My mustang had a spacer behind the clutch and pulley that caused me an issue before. Fixed very easily with a removal, clean and retighten and it was perfect. Took 15 minutes back to 100% quiet. Dealer told me it needed a full replacement new compressor and total cost was $1300. All because the clutch was to tight.
Any help will be appreciated. Rock Auto doesn't show the individual pieces. They list a a/c pulley but I'm pretty damn sure they mean idler pulley which is what I don't need.

Yeah, the parts diagram on Courtesy Nissan looks like it's a just a compressor unit and a pulley. Still, it couldn't hurt to give their parts department a call and ask if they sell a replacement bearing or clutch assembly for the A/C.

I can't remember the maker of the ac unit but saw a similar model but not exact to ours from another Nissan in a internet writeup. It has to be more pieces to it. Kinda like a ball joint is sold as one piece but someone can buy a different seat for the ball joint instead. I'm gonna do some more digging to get part numbers and I'll see what a parts department says but I usually don't like what they have to say in all honesty. The concept on these is simple but shops, parts places make it more complicated
