<p>A differential (10) is provided comprising a rotatable differential housing (14), first (24A) and second (24B) output members, a first cycloid disk (52A) having an epitrochoid groove (65A), a second cycloid disk (52B) having a hypotrochoid groove (65B), a coupling disk (36) connected having a plurality of holes (62) each containing a sphere (20), wherein the spheres (20) are engageable with the grooves (65A,65B) for transferring torque between the cycloid disks (52A,52B). A method is also provided for distributing torque in a vehicle having two axles including at least one drive axle, including attaching one axle to a cycloid disk (52A) having a continuous epitrochoid groove (65A), attaching another axle to a cycloid disk (52B) having a continuous hypotrochoid groove (65B), attaching a rotatable housing (14) to a center coupling disk (36) having a plurality of holes (62), and positioning a torque transfer sphere (20) that is engageable with the grooves (65A,65B) in each of the discs (52A,52B), wherein the spheres are configured for distributing torque along the drive axles.
