| | | | | Anonymous Unregistered | | Anonymous Unregistered | There is a differential gear set in the NP 203. This is what allows it operate as a full time system. When the shift lever is in the Loc position, it locks this differential so that power is positively delivered to both axles. You may have something wrong with this center differential, or it may be a problem with the chain that provides power for the front axle. | | |
