Intermittent Chirp/Squeal from front of engine
I have read a lot of posts and watched a lot of videos on this but have found no solution yet. This intermittent chirp/squeak started early this year on my 2002 Mustang GT. It sometimes lasts several seconds to a minute, sometimes on/off like Morse Code, and sometimes goes away completely. Doesn't matter if it's warm or cold. The only thing that seems to reliably make it go away is when I'm ready to put the stethoscope on something. I've tried water on the ribbed side of the belt. That doesn't seem to change anything. I've replaced the belt, both idler pulleys, tensioner, water pump, power steering pump, A/C clutch assembly. The only things left are the alternator and crankshaft. Nothing seems to be wobbling or out of alignment. I did manage to listen to the alternator with the stethoscope and the noise does not seem to be coming from there. The pulley on the alternator does seem to move in and out almost imperceptibly but spins freely.
