What are the benefits of the D44 vs. the D30? I do know the D30 has smaller 260 u joints, and the D44 has 297 u joints. But the D30 can be upgraded to handle 297 u joints and also use chromoly axles. My main reason thinking of this is beacuse I really like my wheels and dont feel like getting new rims, which just adds more $$$ to my SAS. I also read somewhere that the Rubicon D44 is just a hybrid/modified D30, is this true?
