    Guys, I am running a 10 bolt front axle on my '79 K5. I will eventually convert to eight lug from a 3/4 ton Dana 44. I'm not going to replace the entire axle, just the hubs and whatever else. Here is my question: If the Dana 44 is coming from a '79 3/4 ton truck, will these 2 models use the same spindles? I've heard they use the same ones in some years, and not in others. The reason I want to know is because I REALLY need to replace my upper/lower ball joints ASAP and want to know if I should do everything right now or if I can afford to wait on the conversion and just replace the ball joints right now. I want to replace the ball joints now but want to be sure that I can also use them on the 3/4 ton spindles when I upgrade. Also, what is it exactly that needs to be swapped in this conversion? Please offer your opinions. Thanks.

    First of all, the balljoints and knuckles are separate from the spindle.....meaning the spindle unbolts from the knuckles. I believe that the different spindles share the same bolt pattern and can be interchanged on the knuckle. Basically even if the spindles are different on the two axles, you can simply bolt the Dana 44 spindle onto the original knuckles.

    Thanks. Since the ball joints are on the knuckles, then that means that I can go ahead and replace the ball joints right now as I will NOT be replacing the knuckles in the conversion, right?

    Exactly, same knuckles, no prob, the real question, and why i put in the locker when i did my conversion, is do you really want to take it all apart again to do the conversion or do it all at once? but yeah it won't be a prob, to do the balls now and the convert later.

    IMHO you need to supply more infromation on the Dana(Spicer) 44, and the 10 bolt.
    And even then, to be sure, the part #'s for the spindles !
    1979 was a long time ago, and Dana did not build the 10 bolts,Dana did not build the 10 bolts,Dana did not build the 10 bolts !
