Yeah, I think moly shafts are worth it in most cases. The inner shafts of my D60 are 35 spline, stock. But the stub shafts are 30. So I upgraded them to D70 35 spline stubs, (which are also bigger in diameter, and stronger) and replaced both the stubs and inners with moly's when I did that. Moly allows the shafts to flex under shock loading (having a tire bounce up off the ground and come down hard and get traction). Usually something like that can cause a shaft to twist and break in one quick motion. But the moly actually allows the twist, and then springs back.. where the standard steel is too brittle, and snaps. Axle manufacturers try to make the weak spots of the axle out close the hub ends for ease to the owner in the event of breakage. It's easier to get to the hub, than deper into the axle. But since I'm only going to run about a 39" tire, I don't see any need for weak spots. [;)] So, my axles are pretty much "overkill" for the tires I'll be running. But, I'm old school, and don't really care for trailered trail rigs. I still like driving my junk to the trail. So, I need it to survive, so I can get back home. The Jeep D44's would be great. Especially if you're not going to be running massive tires. A small axle that is actually really strong is the old Toyota axles. The fronts have burfield joints, that are a bit weak, but you can get beefed up burfields.
