I was just wondering if anyone has had their AC/compressor make a loud squweling noise when you start your car. It sounds like the bearing is gone and I was hoping someone would know how to fix or replace the problem. Has anyone had any expierence with this?
They were ball bearings riding on the inside of the compressor clutch. Mine got so bad that one of the balls actually slid out of it's chanel and caused the clutch to freeze.... the belt was just spinning on a stationary pulley, it was not a good thing.
Mine rattles more than it squeals when the a/c is on. If the bearing could be replaced that would be great. You should just be able to pull the a/c clutch and remove the bearing. Then you could get the number off the bearing and get the exact size replacement. But, form what I recall from previous posts the whole clutch is shot and needs to be replaced.
Mine does the same thing in the moning. I get out and spray some "belt ease" all over the belt and pulley and it goes right away. i checked the belt tension and it is fine so it must be a squeaking bearing. Oh well, nothing I can do but cross my fingers and buy earplugs!
Check to make sure that your harmonic balancer is not coming apart. The outer ring will slip against the inner when the engine is cold. Thats because the material/glue is contracted and not sticky when cold, the rings will slip.
Here's how you can tell if it's the BELT versus the BEARING.
Use Armor=All (don't use belt dressing, it lasts too long and goops up the belt!!!). Start the car, spray several sprays of Armor all onto the belt, then turn on the A/C. You may need to spray a couple more times.
If the squealing stops, it's a SLIPPING BELT. If it does NOT stop, it's a bearing.
IT's the easiest test you can do, spend 2 minutes and do it before worrying about the worst.
Maybe you guys can also help me out, cause I'm having similar problems. I hear a loud squeaking noise when the AC is off, but when its on, it goes away. My guess is that the clutch off the air compressor is going bad.
McStealth R/T, or anybody that knows, can we replace the ac clutch without messing with the air compressor? Or do we need to replace the whole thing? From the pictures I've seen, it looks like we can just replace the clutch. Anyone......
