Ok, so new problem decided to show up today. I ran recovery for a rock crawl yesterday so I was in Low Lock all day with the ARBs in and out as needed. I broke a valve stem on one of my 33" MTRs so I put my spare tire on, another brand in a 33" flavor. I've run this combo once before and didn't see any issues, but, today it seems like the center diff doesn't want to unlock. I'm waiting on a buddy to get home to confirm this theory.

What would cause the LT230 to not want to disengage?

Unequal tyre size or pressures make it not want to unlock. Just give the steering wheel a wiggle either way while driving slowly and it should pop out.

I was thinking / hopeful that torque bind is most likely the issue. I'll hopefully be able to get the tire replaced if needed, had to drive on it for 300 yards or so in gravel and no air, tomorrow and see how she goes.

Running them in diff lock on hard surfaces can cause the locking dog to weld itself together, but if you've been running in low box on gravel it's less of an issue.

Jack up one wheel on each axle and it'll let and windup in the transmission go, and if it's going to come out, it will after that.
