HELP!
MC Terrain AWD makes VERY loud grinding noise while making very slow sharp turns, while parking, like tires grabbing... It's a V6 3.6. Have replace power steering pump, drive shaft, transfer case, and had power steering hose length checked, and new fluid put in. It didn't make this sound all winter. Started again when the weather got hot. Could it be the traction control? it does it even when TC is turned off, but is a tiny bit better.

Video? Try simple stuff first. I’ve seen cases where the splash shield behind rotors get bent and grind against brakes, which be louder on slow turns. Check wheel well liners. Shake stuff up and see if it’s simple stuff.
