You CAN break anything. There is no dispute there but lets see how many folks have actually broken a 5.38 pinion, I assure you its not many when compared to how many are in use. Just like the D30 in stock form. if you run 37's there is this forum perpetuated myth that it will explode and your jeep will burn to the ground. The fact is when you look at the sampling size of people running this combination vs. those who have broke using this combination, the potential for breakage is there no question but its not a prolific problem. At some point you have just realize that there are a host of unknown factors in any reported breakage and to blame it entirely on a "weak component" that WILL break you have to look at the big picture. D30 is weak upgrade to 44, why not go prorock44, why go prorock44 when you can go 60? if your gonna go 60 why not 80? Why not Rockwell? Where do you stop in your quest to be "UNBREAKABLE"? I'm just applying a little common sense to this. Folks can obviously apply their own calculation as to what an acceptable cost vs. potential benefit they want to apply to going out and having a good time.
Ok, with that said, If I go to 40x13.50M16's, or 39.5x13.50 Irok radials, am I going to break my beefed up D44's, when I wasn't breaking them with 38.5x15 Boggers that I ran places like Rubicon trail at 8 psi or snow runs where I run full throttle at redline for so long that I overheat and the computer starts shutting me down with limp mode?

I have a friend that I wheel with frequently and he has broken his limited slip D35 3 times and his open D30 once with 33" BFG KM2's, where I've never broken anything in my JK Rubicon with D44's running 38.5x15.0 Boggers. Why? I'm sleeved, gusseted and RCV's in the front and TEN chromoly's in the back. With my big tires, I get through hard stuff with minimal throttle. My friend ends up hammering the throttle, grabbing gears, getting tires off the ground from excessive hop and other generally abusive stuff. Even then, I end up winching him because 33's just don't have the clearance.

If your plans for your jeep is a few fire roads a couple times a year, you will likely be throwing money away with significant upgrades BUT if your bleeding cash ,why not? If you aren't I would say don't let your "weak" parts scare you from ever venturing out of the driveway. Bottom line is money, planning, smart driving, terrain, unknown mechanical defects and installation problems all intersect someplace on the spectrum to determine if you will break but you will never be able to answer the question with 100% accuracy, just do what you can afford to do and let the question answer itself. No vehicle is unbreakable.
