Went out to Ocotillo Wells today (couple of pics below). In doing some light stuff in the dunes I locked both axles in 4L. Then unlocked them when we were done. I did not try this but if you shift out of 4L do they unlock themselves.?
You would use that in a mud hole where high wheel speeds clean out the tread and all 4 wheels are needed to pull due to flex or loss of traction on one side. Or cruising around in sugar sand here in Florida.
I woke up this morning with good intentions, then idiots happened
