The nuts included in the packaging for these ball joint assemblies are missing the intended prevailing torque (self-locking) feature. If the incorrect nut was to become loose, the joining members may loosen leading to a separation of the ball joint. This may result in loss of vehicle control, possibly resulting in a vehicle crash.
