With what you have inside that 14 sf axle it should live forever. I heard from Bruiser the 91, 92 and 93 model 1 ton Dodges had a desirable front Dana 60 in them. Bruiser found my Dana 60 front axle for me at a very good price. I am fabricating a lot of the parts, high steer arms, tie rod etc... myself so that is one reason it is taking so long to finish plus there is a car in my shop in the way lol, long story there. Anyway, as you engineer a plan for the front end keep us posted.
