    The 10bolt that is in the K5 right now has new U-joints, new tie rod ends, and all new ball joints. The dana44 I just got is all tight, but unknown age of any joints etc. Both have 3.07's and I need to swap 4.10's. What are the pro's, con's, interchangable items, cost comparison for gears, and strength issues. Thanks guys!!!

    Just keep the 10 bolt in. There is no real strength difference from a 10 bolt to a D44.

    Correct me if I'm wrong, but don't the earlier d44's have a thicker axle tube than a 10 bolt?

    The axles on the 44 are slightly larger (diameter=strength), and the housing looks a little beefier, but that would probably be it. I have a 44 now that I'm going to rebuild, but you won't gain a whole lot out of swapping a 10 bolt to a 44.

    I would say keep the 10 bolt since you allready have it in your truck, and it has alot of new stuff on it.

    wayne,

    i thought the newer 10 bolts were actually a bit stronger than the 44s...that is what a couple people told me, which influenced me to go 8 lug with my 10 bolt instead of swapping in a 44...

    Just look at the meat on the housing between the two and you'll see which one has a stronger housing.

    The axle shaft diameter is larger on the 44 and there are more splines on the 44 shafts.

    I wouldnt say it's enough to warrant swapping out the 10 for, but if you had a busted up 10, and a 44 fell into your lap I would definitely put the 44 in.

    If it were me, I would stay with the 10-bolt. The reasons are that you have already spent a decent amount of money putting new parts into it, plus used parts are much more common and typically cheaper (a lot of junkyards will try to tell you that a 44 is way better and therefore ask more money.....) for the 10-bolt. The Dana 44 has not been used in a GM truck since the late 70's so any used parts are over 20 years old.

    You can also keep your existing carrier with the 10B, the 44 will require a new carrier.

    Keep your 10 bolt. you won't notice a strength difference. The late 80's 10B have 30 sline shafts and the older ones have 28 splines. That's why the newer ones are a little stronger.
