I hear so many stories of axle/u joint breakage due to the weight of the Bronco. Seeming as the F150 weights a lot less (4600vs3800) that should mean a Dana 44 and 8.8 should be more reliable in the F150. Exactly how much weight does it take to make a difference though? I know someone with a stock Bronco with a 351 that has broken the 8.8 carrier going up a large hill and giving it a bit of gas. I have done the same MANY times and haven't had an issue. That's a good thing but I am still worried about breaking axles, front or rear. I don't think I really do hardcore wheeling compared to most of you, but I do worrying about things breaking. So, taking the weight into account, the 8.8 should be fine, even with locked 38's since there isn't much weight at all in the rear of the truck. The stock solid 44 should be ok with 38's open, but locked should I worry?
