My advice would be to scrap the stock axles and swap in some 1-ton units if you plan to keep the 38's. By the time you re-gear to 4.88's and a new front carrier, plus spend the money to beef up the 8.8" and D44TTB components, you could save a bunch of headaches with a GM 14-bolt rear and D60. That's my plan, starting with the front axle. I just think the shafts, ujoints and whole design of the Dana44 twin i-beam front axle will not stand up even to my 35's. I'll try to get by with just a spool in the Ford 9" rear, then replace that when I break it. I feel like a stock Ford 8.8" axle is even weaker.Last bit of advice is to be patient and wait for a good deal on the parts. look at several axles before you buy one, and get an idea of what you want to pay for it. Again, I would not advise a locker up front, unless it's a selectable one like the ARB. And I've had my Bronco for 4 years, only halfway with the buildup to the ultimate machine I want it to be someday.
