A spindle nut retainer can need replacing when it turns up bent, cracked or missing during a brake or hub service, or when the nut it holds no longer stays locked. Before you replace the retainer, rule out a damaged spindle nut or worn spindle threads, since either can also keep the nut from staying locked.
It is listed for a wide range of models from makes including Ford, Dodge, Chrysler and American Motors, and it is a direct-fit replacement for the 1991-2005 Ford Explorer and the 1983-2008 Ford Ranger. Every other vehicle it fits is listed in the "Vehicles it fits" section.
