I have a 2014 CForce 500. The front differential will not engage when the 4WD button is activated. You can hear the relay click when the button is pressed but the 4x4 doesn't engage.
In order to get to the actuator it appears that the front differential has to be partially removed to access the bottom bolt on the actuator. Before I start disassembly, does anyone know of a source for the replacement parts?
