First of all, I'm not 100% sure it's the rear diff, but the sound is coming from the rear of my Evo VI GSR. When I take a turn, I hear a weird sound...kinda like when your tires barely break loose and make the squealing/chirping sound. Not as loud as if they really were, but that kinda sound. It does it as soon as I start to go straight, and it stops once I AM going straight. I don't have to be taking turns extremely hard, but a little hard and it does it, and only on very sharp turns where I can't even get over 20 km/hr. Is this just the normal sound of the AYC working or is this bad? There's no metallic sound or clunking, or any weird feeling through the car/steering...just this sound.
