    <font color=green>The D44 is a bit stronger, I would go with it. It's not so much stronger that I would bother swapping out a 10 bolt for one, but if you have to replace the whole axle anyways, you might as well go with the stronger axle.

    Strength is the same...so go with whatever is ez to find parts for in your area.

    If you can, and if the money allows, try to find the "Executioner-Special" 12 bolt front axle. [​IMG]

    I personally am fonder of the 30 spine 10b front end... if you get rid of the carrier with arb or something like it you get a stronger axle.... and the theory is when stronger u joints are developed this axle will benefit from them.... or course there's always the chance with the joints you'll twist shafts... basically I think it comes down to more of what you like, cost and are there the parts you need in your area....

    I would get at least 3/4 tons, they usually come with good gears already.

    If you can find them, or if you just have to have them, 1 tons are the way to go. They come with good gears, they're strong, and heavy.

    I am satisfied with my setup. I have a 14 SF rear and a 10 bolt front, both with 4.10s. I have the gov-loc rear which is okay but not really in the mud.

    I am either stepping up to a lock-righted 14 SF or a FF with a Detroit.

    I might be wrong but I from what I have read the dana44 and 10bolt are pretty much the same in strength. From my dealings with parts sellers 10 bolt axles sure are easier and cheaper to buy. But what do I know?

    I think the reasons for a 10 bolt to be easier to find and get parts for is becuase they were from 78 to 91(14 years)were as the d44 open knuckle was only 78 and prior..8 or 9 years..

    add to that, a few years ago there were absolutely ZERO dif options for a 10 bolt. so any serious wheelr had to swap to a 44 to run traction aiding dif. so they were the one to find and therefor are chewed up. as for parts are easier to find they still make 44s so new parts are on the shelf.
    the 44 casting is supposed to be slightly better thickness.

    for the little boy once again, 1/2 and 3/4 ton front axles are the same.

    Correction: '77 was the first year the 10 bolts were available. [​IMG]

    D44's were still available up to '79 and also up to '82 only in the GMC line.

    D44's and 10 bolts were like "options", but I doubt anybody ever selected one or the other off the assembly line.

    m.j., 1/2 and 3/4 ton axles ARE NOT the same. my suburban is 3/4 ton and i have a 14 bolt sf and 30 spline 10 bolt, both of which are 8-LUG. show me an 8-lug 1/2 ton.

    In m j's defense, he was simply stating the 1/2 and 3/4 ton axles are the same, and they are, with the only differences being the bearing hub and rotors. [​IMG]

    D44 in 6 lug and 8 lug are the same axle. If you took the bearing hubs off of a 1/2 and 3/4 ton and laid them side by side, you would never be able to tell which D44 came out of the 1/2 or 3/4 ton. You could only tell by the bearing hub. The same goes for the 10 bolt axle.

    So, m j is right on the 1/2 and 3/4 ton axles being the same.

    Once again smartass,

    I never said front axles were different on 3/4 tons, or stronger. I know they're not. But they usually have good gears already.

    I don't really have the money to do gear swaps, so it's cheaper to buy the used housings/gears already set up and ready to run.

    Gears are the only reason I even changed my front axle twice. I have never broken a front axle, only rears. I have upgraded each time. I had a 10 bolt rear, then a 12 bolt, now the 14 SF. I destroyed the 10 and 12 bolt, both. I am going to do a 14 FF one day I suppose.

    I am 2nding what ThatK30Guy said. I converted my frontend to 6 lug because I don't have any good 8 lug rotors right now. It did come from a 3/4 ton truck, but for now, it's 6 lug.

    All the parts are exactly the same anyway. On 10 bolts, only the backing plate and rotor/hub assembly is different. I think they even use the same wheel bearings. Spindles are identical.

    This has been covered a million times here, so if you don't believe us, do a search!

    If you are going to leave the front diff open then I would use the 10B. That way you won't need a new carier when you regear. Around here it is easier to find spare 10B shafts.

    Wes,

    I'm trying to do an "inexpensive" 8-Lug conversion so I can add my 14BFF out back. The '72 K5s (aka mine!) came with a D44, but with 6-Lug spindles/brakes/etc. Correct so far...? [​IMG]

    I have done some quick calling around and YES the D44 8-Lug stuff seems expensive ($500+ whether you want the whole axle or just the conversion parts).....am I wasting my time looking for 3/4 Ton D44 stuff...? Should I instead call around for the "less desireable" 10-Bolt axles, and steal the spindles/hubs/rotors/etc from it?

    I haven't checked around on pricing yet for 10-Bolts, but if it's true that they're not as hard to find, I might be able to get a better deal?

    Have I got my facts straight about the 10Bolt vs. D44? Sorry, for some reason this front axle conversion stuff is NOT sinking in!!!! [​IMG]

    For the most part, the 6 to 8-lug conversion parts are the same and interchangeable between the Dana 44 and 10-bolt. There are a few differences throughout the years, but if you get everything starting at the spindles from an 8-lug 10-bolt, then it will bolt up to the Dana 44.

    You will need:
    spindles
    backing plates
    hub and rotor assembly
    wheel bearings (preferably new)

    The brake calipers and locking hub should bolt up to these parts.

    A lot of people think the Dana 44 is alot better than the 10-bolt which leads to the higher prices, plus the 44's have not widely used in GM vehicles since about '76 or '77.

    Hey Tim, knock off the comments like smart@$$.... did you not read what what was said on the knocking that off? We all agreed it needs to stop. There's no point in trying to start something where a comment like this pretty much will. You're 20 years old and don't know it all (I'm 24 and don't know it all, so don't expect you will anytime soon [​IMG]). Accept it and move on.... [​IMG]
