Although I am running a stock D30, locked, with 4.88s and 35s...I feel it will eventually give due to the difficulty of some of the trails I have tried.
I think "The front axle (D30) locked with chromoly shafts is strong enough to handle up to 35" tires" is a more correct statement.
The only real advantage of swapping in a D44 (out of a rubi, aftermarket doesnt count) is the ability to run deeper gears. Everything other than the inner spline count (and obviously the differential) is exactly the same as a D30.
