    I thought the inner shafts on D60's were 35 spline until I searched a bit and see they were but only after a certain year /forums/images/graemlins/dunno.gif My axle was one that came out of the military trucks. I was planning to order a locker but they make them for both 30 & 35 spline setups. Any way to tell besides opening it up first??

    Best is to pull it open. AFAIK the 30 spline are rare with kinkpins however. Mine is a 1990 dodge and has beef 35 spline.

    Thanks guys. I'm pretty sure it's 35 too. I just wanted someone else to ease my worries...

    If it originally came from a GM and has not been modified, it's a 35 spline AFAIK. The only exceptions I know of are old Dodge and Kaiser units, and maybe Ford (but I think they are all 35 too) or aftermarket conversions. If it's from a CUCV, it's definitely a 35 spline inner.

    I think it's also possible to have swapped the side gears from a rear (or even entire carrier I suppose?) but I have no idea why anyone would do such a thing.

    Yeah its a 35-spline...the only changes I know of on the GM side of things is the older shafts were "neck-down" and the new ones are not...

    I could be wrong, but I thought the 30 spline D60's were rear axles only.....
    I'm no expert so that information could be incorrect. This was before the "new" style D60 front axles came out with balljoints, so maybe those have 30 spline inners as well.

    I have never heard of a front, open knuckle D60 (in any brand vehicle) having anything less than 1.5" / 35 spline inner axles. /forums/images/graemlins/deal.gif
