dana 44 locking collar in the arb will be the first to go, something pinion related after that.
it will probably last you quite a while really.... I'm not trying to rip on you but given that you only really get out a couple-few times a year and not much if any is out of state.... you dont get too many undercuts and you wont see a situation that will break it very often so it might work out....
This is a PSA for everyone considering a 44/60 hybrid axle..... this is the perfect reason NOT to build one
sorry scoots... couldnt help it!
