Ok, I just replace the wheel bearings and rotors two weeks ago. Today on the way to football when I hit bumps I can hear a scraping sound under front drivers side. I thought it was the brakes, but when I rolled down the window I couldn't hear the noise at all. So I figure its not the brakes. I also have a thumping sound under the front when I hit bumps, but the ball joints were just checked and checked good. Any Ideas
