troubles
First, check your fuse. Then see if you have power to the front thermal actuator on the differential housing while the shift lever has been engaged. If you have voltage then chances are it is the actuator itself. These commonly fail. You can buy a newer faster style or you can buy an aftermarket manual set up that is basically a cable you control from the cab to engage the front. It is called posi-lok. Thats what i put in and it is trouble free.
