How bad are the Alloy Dana 30 shafts?? Quadratec just had a sale on Alloy inner axles for under $160, way under for passenger side. I'm putting a Torq locker in the front of my LJ and understand the stock axles won't handle a locker. I'm not a bust my jeep for the fun of it guy, want a locker just because I've got hung up when a locker would've made I no problem.
