I have a 2005 GMC Envoy XL 4x4 4.2L and there's a noise that sounds almost like metal on metal grinding sound. It's not very loud but it's definitely there. However, I was able to drive 800+ miles back home from OBX without any problems.
The noise gets louder on right turns and is pretty quiet on left turns. I recently changed the brake rotors, if that makes a difference. Any help is greatly appreciated.
