I have an 84' jimmy w/ the 6.2l diesel. I don't mind it at all. The stock axles are under it still. I understand that they a too weak I am afraid of breaking them. They have 3.73's w/35's. What opinions are there about changing the gears? Will a lower gear be more inclined to break axles? I just broke my driveshaft. It broke the front u-joint and both yokes on the rear driveshaft. I just moved from Utah to Deleware amd embarssingly enought got stuck in the flatest state in the union. Will the 10 bolt handle a locker? I don't want to change my tires and rims. The truck used to see moab with open diff's and did fine. Now it will see more mud(if it gets to see anything here). I don't beat it but I diffinetly like to use it. My real question is "are to 10 bolts strong enough and if not, what is the strongest least expensive option? All sugestions are welcome.
