Abstract
An axle locking device designed for installation in a standard vehicular differential case is defined by two mating unitary bodies piloted between a cross member and the interior walls of the case. In a preferred form, the halves are symmetrical, each half including a pair of pilot surfaces defined by cradles which engage the cross member. Other pilot surfaces are disposed in three orthogonal planes for engagement with the interior wall surfaces of the case, particularly the axle and cross member bore areas. Collectively, the pilot surfaces of the locking device eliminate any requirement for positive securement by fasteners of the locking device to either the cross member of the interior walls of the case.
