OK, I broke the u-joint yoke on my passenger side axle stub shaft on my 1973 J-4000, as well as the u-joint itself. I have a closed-knuckle D44HD with the weak, tiny 5-260X u-joint. Does anyone know if I can swap in D44 axle shafts from, say, a 1976 J-truck with the stronger 5-760X u-joint?? I'm willing to take the ball joints out of the knuckle to fit the replacements if needed. They are both 30 spline shafts, so that's not a problem.
By the way, replacing the housing is not an option, since the pinion housing has been destroyed. Shafts are good, though.
