4 wheel drive

on the right side of differential there's an axle tube that goes to the right side half shaft, the 4wd actuator is on top of that tube, i believe in 93 it is still freon charged so it can go away slowly and when it is cold, just unplug the wire and unscrew, you can update to an electric actuator, but on some models you need to grind the axle tube a little
