Haven't been in 4wd or used the lockers since EJS, pulled into a rest stop and got this. I have the Z-automotive locker bypass once I figure out which locker is faulty.
Well that sucks! I would double check to see if maybe the wiring on axle plug has been pulled on when at a full droop. This happens most on the rear and can damage the wires and it can take some time to show itself.
