front differential will not engage
 

my 4wd just **** the bed on me the other day. thought it was frozen so i just left it but now it wont engage the front differential at all. its engaging at the transfer but thats it. whats the best route to go without ripping the whole front out of my truck. is there a fuse possible for the front actuator or some other possible easy fix. is it possible to remove the actuator to test it? anyways need some help. had to get a dodge to pull more out of a snow drift and i never want that to happen again lol
