Lock washers are designed to prevent nuts from loosening under vibration by applying spring tension and friction. They are typically replaced whenever the axle nut is removed during brake, bearing, or wheel seal service. A worn or cracked lock washer can lead to loose wheel bearings, which poses a serious safety risk.
