A motor vehicle has a frame and drive mechanism mounted to the frame. A differential gear box is mounted to the frame and coupled to the drive mechanism. The differential gear box includes a housing cover, differential planetary gear assembly mounted within the housing cover, CV joint housing mounted within the housing cover and rotationally coupled to the planetary gear assembly, and CV joint bearing having a plurality of rounded bearing surfaces contacting the slotted bearing drive surfaces. The CV joint housing includes a cavity with a plurality of slotted bearing drive surfaces formed in a sidewall of the cavity. An axle has a spring-loaded plunger disposed through a center portion of the CV joint bearing and contacting a bearing surface formed in the cavity of the CV joint housing. The slotted bearing drive surfaces permit angular movement of the CV joint bearing within the CV joint housing.
