I have this problem when I apply my brakes, just as I'm about to stop my brake pedal has a slight vibration and creaking sound that is driving me crazy. Also pedal is softer than usual. Pads and rotors are good, pls. Help.
Front diff on my 4WD vibrates when ingauged in 4 hi. Runs smooth in 2WD. Dealer has checked u- joints and driveline components and can't pin point the problem.
