At idle with the A/C on, I hear a loud rattle noise. Kinda like a tin can with a bolt in it? Is the compressor on it's way out, or maybe the pulley bearing? Thanks!

Could be a/c clutch faceplate bumpers, there are rubber bumpers in the plate to damp the sudden kicking on of the clutchplate, the rubber crumbles over time to be gone and then the racket.

You generally have to buy the entire clutch to get that part but hard looking will sometimes turn up a drive faceplate by itself.

I've used a scrapyard part but if you do not do anything to closer match the different wear patterns between your old rear and your 'new' front then the racket may even get worse. I dress the friction surfaces with a fine tooth flat file to make both as flat as possible and then install the plate and it must be set with washers to get a .015"-.030" air gap or clutch doesn't work right. I've fixed one to run for years more for $5 in parts.
