I am a trained driver I have sub contracted to kelly haze as a abs recorder for new vehicle.
Front wheel bearings failed. This caused wheels to become loose. Vehicle made a loud terrible grinding noise. Took vehicle to mechanic who indicated bearings could have sheared off. Abs brake failed. Also, u-joint failed causing grinding noise and vibration.
