This is a really classic and common old car problem. I see it all the time but this is the first time it's started happening to my own car.
Basically when I first turn the car on, there's instantly a pretty horrific squealing that sounds belt-related, and develops to an even higher pitch as I pull out of my parking spot cutting off the wheel to the right or left side and drive away.
What could be the issue? I drive a 2004 Ford Ranger. The main belts are not brand new, but are alright.
