Default 2003 AC Compressor Disengaged Clutch Noise

Folks-

Got 65K miles on my SSEi.. I notice when the A/C is off, there is a "raspy" noise under the hood.. Engage the A/C compressor and it goes away.. Today, I took the belt off and the pulley spins with a dry bearing sound. It spins good with just a small side to side play in it.

Anyhow, anyone have/had this noise? Is it something I need to fix soon (I asume replace the compressor clutch), or is it just normal to have this noise..

Thanks.. Weird problem it seems..

Danthurs- Thanks for the quick reply.. Yeah, I read that and figured that didn't apply since I am hearing the bearings make the noise.. You still think it needs adjusting??

Can't say I've heard of any compressors loosing bearings. Every time I've had one making noise, it'* been the clutch.

Danthurs-

I went out there and was able to run a .15 feeler gauge easily all the way around that gap between the clutch and pulley. .20 was a tick snug in the area pointing towards the crank.

In fact, I took a LED flashlight and can see light shining through the gap all the way around between the pulley and the clutch. With the SC belt off, I started the car and ran the A/C.. Of course, the gap dissappeared.. Turned the AC off and I can 100% see light all the way around once again. I just don't see the clutch dragging the pulley whatsoever. Does this tell you anything?

I am like you though.. Never heard of a bearing going.. Only thing I will say is we had flooding rain in east TX the day or two before I noticed the loud noise coming from under the hood.

Try spraying soem oil in the clutch and see if that does anything. It could be a bearing.

I did auto HVAC for years, allot of compressors need the air gap adjusted but I have also changed many bearings.
