The logic goes like this in breakage, and Bentparts hit it on the head, the locker in
front increased the traction available, and the lower gears added a finesse factor
that was missing with higher gears, that with the added cushion the automatic gives
to the driveline the breakages have stopped.
This was/is not my truck it's Wicky something I can't remember his screen name's truck,
we did the swap to auto after I told him about the lack of breakage on my truck, in fact
I converted him over to his Tracker from a fullsize Ramcharger because my truck performed
better
Looking back, I broke the longside 22 spline because of lack of gearing, 4.62s stock T-case
on 33 Swamper LTBs and no front locker, since changing to 5.83s I have had no problems,
and now with the full gear package and 26s up front I don't worry about axle breakage, tho
I'm sure I could nuke them if I drove it wrong
