    Every other post I see is 14 bolt this and 14 bolt that. Well I figured I should get in on the fun, lol. I'm swapping in a 3.73 12-bolt in my '82 w /31"s. So I figured I'd drop the pukey 2.73 12-bolt in my '81 w/32"s.

    I have noooo idea what half the talk is about these.
    What's the difference between a full and semi-floating axle?
    What kinda trucks had what?
    How can I tell?
    Which do I want?
    I have 10-bolt front with 6 lugs and 15" rim, do I have to convert that to 8 lug 16" rim or can I do something to the back.

    I have a good selection out my uncle's so for free I figured why not?

    Full floaters don't use the shafts to support the weight of the vehicle like semi floaters do. This takes a considerable amount of strain off the shafts. They also use two bearings per side as opposed to just one per side in the semi floaters.

    Your frontend is a full floater, your rear is semi floater.

    Most all big rigs and heavy equipment use full floaters.

    Poundin' the ol "pavment"!

    Like red dwarf said, the weight of the vehicle rides on bearings instead of the axle. Also, there is no c clip that holds the shafts in, but to get the drums off you have to pull the shafts out, then take the big bolt off the spindle that holds the drums on. Personally, I have the 14 bolt ff because of it's superior strength. The only disadvantage is that you loose some ground clearance, but i really don't care. Also, the detroit is only about $320, and you get bigger brakes. For converting the front, you don't have to, but you would have to carry 2 different spares. Hope some of this helps. Later - Doug

    Well, the difference between the semi and full floaters has already been covered. I believe the 14Semi axles started in the early '80's, but Im not positive. I know my 79 had a 14 Full floater. Personally, Id go with the 14 FF. Do it once, do it right. As far as the front, you can convert it to 8 lug(so you dont have to carry 2 spares), and run 15" rims(although you must grind the calipers) so you can use your old tires.

    Is that to say that the front 10 bolt dana44 can handle the stress just fine? Are we talking a 1/2 ton Dana44 or a 3/4 ton?

    What, Me Worry?

    A 10 bolt or D44 will take alot of abuse up front with upgraded shafts, etc. While not the meatiest axle on the planet, they're great for part time 4 wheeling and every day driving. Personally I don't see a reason at all to swap them out, unless you are into the really extreme rock crawling, or running 44"s.

    Special thanks to those lost from IAFF Locals 94 and 854 - You shall never be forgotten

    Not that i'm in love with my 10 bolt, but i haven't broken anything yet. I run 35x14.5x16.5 SSR's and I'm not a pussy about driving my k-5. I have a converted 8 lug front, and it does nothing for the strength of the axle, just so i don't have to have 2 spares. I also have an eaton posi. I'm not saying that i won't break anything either, and i'm getting a 60 in the summer when i upgrade to 42's. Later - Doug

    Also if you run 15" wheels on a 8 lug Dana 44 or a 60 they will have to be steel. And you will have to grind the calipers to clear.
