High pitched whine, like a bearing noise
Car has rungreat, took it for a drive and about 5-7 miles in it starts making a high pitched whine. Thought it was a belt idler pulley, so I tried to lube them and have changed them, no dice. It's not in the drive train as it does it standing still but not at idle, just above idle at about 1500-2000 and goes away under acceleration and returns when cruising. Ac belt is off the car, so I'm thinking either water pump or alternator. The ps fluid is full, no leaks. Any help would be greatly appreciated. If the rain will stop I'll start the car without the belt on and see if it's still there.

Yeah that was the first thing that came to mind when i read your post. I hhad a 95 z28that did something similar to this to me. Mine gave me a warning before the squeel though that i didnt pay attention to. I noticed when i accerlerated my voltage meter went up to normal levels but at idle it would drop down to barely above red. Sure enough a few weeks after this started i got the squeel that souns alot like whhat youre describiing
