  Retainer Nut

• Description:

  This is the genuine Ford nut retainer lock ring, a 3/4 inch spindle nut retainer from the HN2 base hardware family used at the front wheel bearing on Mustang and a broad range of other applications. The retainer fits over the adjusting or spindle nut and locks it in position so the carefully set bearing preload cannot change in service, preventing the nut from backing off or tightening on its own as the wheel turns. It is the locking element that keeps the front wheel bearing adjustment secure, and it pairs with the spindle nut in the hub assembly. A bent, cracked or worn retainer, or one removed during bearing service, must be replaced so the adjustment stays locked; reusing a deformed retainer risks the nut moving and the bearing going loose or binding. Fitting a fresh retainer restores secure, reliable bearing adjustment. For a proper repair, set the bearing preload to the factory procedure first, then install the retainer so it positively locks the nut and aligns with the cotter-pin or locking provision, and confirm the wheel turns freely without play. Inspect the spindle and bearing components while apart. This retainer commonly works together with the matching spindle nut, so service them as a set. Confirm your application before ordering. Genuine Ford construction ensures the retainer matches the original size, locking geometry and material for a secure, correct hub assembly.
