The 2nd Gen axles are more like a Con than a Pro. There is a handful of peeps blowing front diffs, and with the aluminum housing, is subject to crack (like in the picture). As for rear axles, have you seen the ring size in the first gens? It comes close to a 9.25" diameter. Thats 1/4 inch bigger than in the Ford 9" I'm running. I am by no means, saying one generation is better than the other overall. But when it comes to axles, Nissan dropped the ball on the 2nd Gen when not keeping that H233B (SP?)
