I have done some research on prior posts however the description of failure is opposite of what I'm experiencing. All of the post that I've read said that there was a grinding noise when the center diff lock switch was engaged . My grinding noise I experience when the diff lock switch is disengaged after I disengage the truck it will not move. I was trying to get a good idea of what I should be ordering due to the fact that this is a daily driver and I would not be able to take it apart and leave it down for an extended period while I order parts. Any opinions and insight would be greatly appreciated.
