[s-cars] A/C compressor noise

[Young, Steve]

Eugene...

I just had to do the A/C Compressor on one of my C4 A6Q's.  Check this
place out.  Much better prices than you got from your guy.

1 year warranty, and I got an OEM manufacturer part.  If you go this
route, you need to replace the drier also to get the warranty.  Good
luck.

BTW, make sure you look at the pictures once you have selected your
compressor/drier and match them to what is on your car.  My '96 A6Q
turned out to be a late build and had the '97 style compressor.  Cost me
return shipping.

Subject: Re: [s-cars] A/C compressor noise

Folks,
First of all, many thanks to all who replied to my post regarding A/C
compressor noise from a couple of weeks ago.  To refresh everyone's
memory, my '95.5 S6 makes a whirring noise with a faint clattering when
the A/C is off.  The noise goes away when I turn the A/C on.

I finally found the time to do some more troubleshooting last night.
I removed the serpentine belt and turned the compressor pulley by hand.
It feels rough, and it makes a grinding noise, so I'm pretty sure that
the compressor clutch bearing is hosed.

My local independent mechanic quoted me $1k to replace the compressor
($750 compressor + 2.5 hrs labor), and he recommended that I replace the
whole compressor, not just the clutch.  Once again, I appeal to this
list's wisdom in the hope of saving some money:

1. Do I really need to replace the compressor, or can I get away with
just replacing the clutch?
2. Could you guys please recommend some reputable online sources for an
A/C compressor and/or clutch?
3. Bentley shows the clutch replacement procedure with the compressor
sitting on a workbench, but...can I replace the clutch without removing
the whole compressor from the car? (I would like to avoid disconnecting
the hoses and the associated discharge/recharge of the
system)

Thanks again,
Eugene
