Hello everyone. A mechanic and i pulled out transfer case and replaced front seal and bearings which are located in the front nose of the transfer case and put it back and H-N-L works but center diff lock is not engaging when i oress the button... We took the diff lock motor apart before putting back the front nose that must have something to do witj? Wires and everything is ok. Im guessing when we put back the center diff motor we missed aomething to adjust??
