Say you have a 1990-1995 toyota truck, and it has the ADD(automatic differential disconnect) system. The front half shafts spin even in 2WD. When you shift into 4WD, a switch in your tcase changes a set of air valves, which cause the actuator in your differential to slide a sleeve that connects the driver side half shaft and your differential. My question is, if you want to put manual hubs on your yota, do you have to somehow bypass this ADD mechanism, so that the ADD is always engaged? Because, even if you lock up your hubs, if the ADD system isn't engaged, then you have no 4WD. How do you put manual hubs on an ADD equipped, which most 90 or newer yotas are, truck? This question has been boggling my brain for a while now. Later.
