A/C compressor is making noise. Replace it or rebuild?
I recently had to replace the tensioner assembly. My A/C compressor was getting noisy before I replaced the tensioner. With the new tensioner installed I can hear the compressor. When the A/C is on it is louder and with it off it is almost silent. It is still blowing cold but I know it is going to fail soon.
Is it possible to rebuild it? If not what brand compressor is recommended? The factory option is almost $800. I am hoping there is a much cheaper aftermarket option that isn't junk.

I've actually seen rebuilt compressors, and while I have no experience with them, I can't imagine them being that bad considering power steering pumps are rebuilt all the time with a high rate of success

I haven't driving my car in a few days but I did ask the tech that replaced the tensioner and belt last week to listen for the noise. After he replaced the tenisioner I heard a squealing sound a few times after starting. Well he couldn't narrow it down in the parking lot with the engine cover on. This was on Tuesday. He told me it should be ok to drive since it was intermittent. I took a dealer car home Tuesday night because I was going to an auction the next day. Well I didn't drive my car again until tonight. When I first started it I heard a slight whinny noise but it went away quickly. I drove over 30 miles home and it seemed ok. I got home, changed my clothes and headed out to watch the Celtics game. After the Celtics got crushed I got in the car and attempted to back up. I heard a very loud whining noise and then the battery light popped on and I had no power steering. I knew what had happened. What caused it I still don't know for sure but something locked up, a/c compressor or power steering pump. Of course it was pouring out but I was able to cut off the serpentine belt and luckily I made it home on battery power.
Tomorrow I will try to diagnose what locked up. It could have been the A/C compressor but I am leaning towards the power steering pump. I will post more info when I have it.

It happened to me, those noise coming from AC compressor is a sign that there less oil or none at all inside the compressor. It seems like your AC compressor seized on u. Thats why i suggested on my previous reply to put a pag oil. It will cost u $1000 at least for the OEM parts.

Those crank pulleys come apart a lot actually - I've seen it 3 or 4 times and other techs I know have all seen it a lot too. It's pretty crazy stuff!
As far as your A/C Compressor (if you do end up needing one) don't bother rebuilding it - just buy one from RockAuto.com, they sell the OEM part (Denso) for $200 and it includes a new clutch and coil.

I have felt today an added vibration when starting the car. The engine vibrates, and i hear a higher than normal roar from the engine while in the car. I turned off my AC, it goes away, and comes back when AC is on. AC works fine.
They are very similar symptoms like the OP. There's also an intermittent screaming noise that rarely came on lately, and it sounded like from the fan area.
Am I safe to say crankshaft pulley as well?
