Yesterday. I was in PA. I stopped at this waterfall to check it out. I accidentally hit the elocker switch ( LowRangeOffRoad) elocker is swapped so no ecu. Will turn on whenever. However I confused my self and second guessed. Slightly hitting the button up ( ON ) Position. For some odd reason. I though it was off position and held it down for few seconds thinking I was turning it off. But I actually engaged it ( truck was parked ). Then after driving around wavy Road roughly 60 mph. And making few slow 90degree turns at intersections. About 10-20miles I realized that the rear was locked when I came to stop sign and made a turn. I turned it off. And double checked everything by turning it back on and making sure it was still locking. I don’t think I ****ed anything up. But it was STUPID OF ME !!! The rear did not make any odd noises. But I’m just overthinking about it right now.
