Everytime I go up or down a drive way, or if I am shifting gears between Drive and Reverse while turning the steering wheel, I hear cracking or popping noises from the front end of the car. I just had the ball joints replaced last year, but it was making that sound even when I got it back from having them repaired. No creaking noises when I drive straight just when I am at low speeds. Anybody know what it could be?
