Abstract: A locking differential assembly includes a differential case defining an axis of rotation and a gear chamber. 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 opposite the first end for selectable rotation relative to the differential case. At least two pinion gears are rotatably supported in the gear chamber in meshing engagement with the first side gear and the second side gear. A solenoid is at the first end. A plunger is selectably magnetically actuatable by the solenoid. A lock ring is selectably engagable with the second side gear to selectably prevent the side gear from rotating relative to the differential case. At least two relay rods are each connected to the plunger and to the lock ring to cause the lock ring to remain a fixed predetermined distance from the plunger.
