Hey all My wifes Envoy is making a metal on metal noise in the front end when she cranks the wheel and hits some bumps. At first I thought it was the break dust shield so I took the front tires off and spun them but no noise... While I was in there I noticed I need to do upper ball joints but dont think that this would make that kind of noise. I had her drive around while I was walking next the the vehicle but still could not pin point the sound. Any ideAs?
