Abstract: A differential assembly includes a differential case having an axis of rotation. A first side gear and a second side gear are disposed in the differential case. The first side gear defines a first internal spline having a first internal spline major diameter. The second side gear defines a second internal spline having a second internal spline major diameter. A cross-shaft assembly is disposed in the differential case. The cross-shaft assembly has an annular yoke defining an inside clearance cylinder coaxial to the axis of rotation of the differential case. An inside clearance diameter of the inside clearance cylinder is greater than the first internal spline major diameter or the second internal spline major diameter. A plurality of stub shafts is equally spaced around the annular yoke. Each stub shaft is disposed perpendicularly to the axis of rotation of the differential case.

Abstract: A locking differential assembly includes a differential case defining an axis of rotation. A first side gear is at a first end of the differential case. A second side gear is at a second end of the differential case. A stator is disposed at the first end. A solenoid is fixedly attached to the stator. The stator is selectably magnetically actuatable to translate an axial translation distance by the solenoid. A lock ring is selectably engagable with the first side gear to prevent the first side gear from rotating relative to the differential case. At least two relay pins are connected to the lock ring and in contact with the stator to space the lock ring at least a predetermined distance from the stator.
