Are you sure it's screeching not clicking? Because if it's clicking, the major suspect is the CV joint.Whenever I turn left very sharply I get this weird screeching/grinding metallic noise from the right side of the car. I have to turn very sharply to hear it, and it is pretty loud. For example if I am making a U-turn turning left it's there, however on normal turns it's not. If I make the same turn right it's not there. I think it's actually coming from the rear wheel, but I am not 100% sure.
Anyways, it sounds pretty nasty so I was just wondering if anyone has any idea what it could be? I got a 97 V6 with 190,000 miles.
