    I've been searching around for an answer for this but haven't had any luck with anything definitive.

    Is the only difference between the two the brakes and the bolt pattern?

    They are all 30 spline shafts, correct?

    Anything else?

    <font color="green"> Brakes and bolt pattern is it. They are identical from the knuckles in. There were *some* 3/4 ton ones that had thicker axle tubes, but not really enough to warrant mention. </font>

    I believe they also have different spindles for more weight carrying capacity also.

    Spindles are not different from 3/4 to 1/2 ton.

    The difference is when they were made. The ealier ones, 1st design, had the smaller spindles and axle shafts.

    The later ones, 2nd design, had the larger spindles and axle shafts.

    Same for 1/2-3/4 ton.

    The only real differences are the lug pattern, brakes, and internal or external hubs. For the most part though, I think, the 1st designs had the external hubs 2nd design had the internal hubs.

    I'm not sure the cut off years for the 1st and 2nd design- I think its right around '74-75. /forums/images/graemlins/thumb.gif

    What is the difference between an internal/external hub? Which is stronger?
