Please pardon me if my wording on this stuff is wrong. My differential locks wont disengage. My middle locker is engaged and the front locker are engaged and my rear lockers are not engaged. I didnt even think this was possible. I thought they had to lock in progression. Is there anyway to manually disengage the lockers. My dealership here knows less then I do, and I know next to nothing. So if anyone can help, please let me know. Thank you in advance.
