Firstly i have a 3.0L 1999 4x4 XLT Ranger with AC.
The other day i replaced the alternator, and everything went fine with that. Except
about a day later the pulley system started to squeal, loudly and constantly. It squeals when idling and traveling at constant speeds. The only time it does not squeal is when I'm accelerating.
So i checked the alternator, and the noise is not
coming from it. Since then, i've replaced both the Idler and Tension pulleys, and it's still squealing like a banshee. I guess the next logical step is to replace the belt, but after that I have no idea were to go.
