LOL!! I just love the kind of really bad advice people dole out these days. Truth be told, you are more likely TO BEND your front axle by installing a truss than without and really, a bent axle housing is the least of your concerns. Even bent, you can still drive your Jeep whereas if you break an axle shaft, you could be on the trail for a while. Do yourself a favor and not throw anymore money into your Dana 30 than you need to. Even if you built up the housing, your weakest link will still be the shafts and ring & pinion.
Play with your Jeep and play hard if you want but save up for a Dynatrac ProRock 44 in the mean time. If and when you need to upgrade, you'll be glad that you save up your money for a real upgrade rather than wasting it on a Dana 30.
