So, I think the bearings are going out on my A/C unit, so I will probably replace it. Its making a high-pitched squeal at idle up to 2K rpms. Its not constant and happens randomly at start-ups and while sitting at lights and stuff. I just replaced the alt because I thought it was coming from that, but its not.
So, anyone know of an easy way to go about replacing it? Its a 94 Z28. I hope to do it this afternoon. Any help would be nice.

You sure it's not the water pump? Otherwise you don't need to replace the whole compressor because unless the A/C is on, only the pulley itself is "spinning" freewheeling acutally like a ikdler pulley and would continue to make noise.

So, I would just need to replace the bearing? It makes the noise when the AC isn't on.

being your not sure where noise is coming from try the old stethoscope
to pin point where noise is coming from.i just replaced alt belt & had similar
noise thought it was bad tensioner.after using long screw driver to see where noise was it was a/c clutch when a/c is off(clutch not engaged)

Do some sluething and be sure. Otherwise the bearing is normally part of the clutch assembly.

Well I found the location of the noise. The clutch on the compressor is shot. Its rubbing and that's what is making the noise. I pulled the fuse so it wouldn't click on and I'll get it replaced in the spring. It is in a bitch of a spot too.

They have a good tendancy of crapping out when they haven't been turning for a while, completely forgot to mention that.

Good to know. Yeah, I don't use it much, helps save gas. Plus having the windows down allows me to hear the motor better :)

That tells me the A/C is working fine and fully charged on R-290, 2 windwos down and 90 mph :icon16:
