    could not find this on here, what is the difference between a 1/2 ton and 3/4 ton 10 bolt front axle housing? I bought a truck (79 1/2 ton Chevy) with the original axles swapped out for what I was told were 3/4 ton, the rear is a 14bolt FF and the front is a 10 bolt. The person I purchased this from turns out was not the one who build this truck so he doesn't know alot about it so I'm trying to figure out what I have here, thanks.

    The search button does not exist for non-members anymore.


    The only differences between a 1/2-ton and 3/4-ton 10-bolt are the backing plates and the rotor/hub assemblies. See this thread.

    AFAIK, 10-bolt fronts are identical from the knuckles in for 1/2 or 3/4 ton.

    The only difference would be in the outers, i.e. one is 6 lug and one is 8 lug. (Well, the calipers on the 3/4 might have the larger bore, but physically the outers are interchangeable from 1/2 to 3/4, and in fact, from D44 to 10b fronts.)

    If the front is 8 lug, it's 3/4, and if it's 6, it's 1/2 ton, but those parts are swappable without switching housing. Make sense?

    thanks, the front is 8 lug so it sounds like I have 3/4 ton my next question is will this be able to hold up to a set of 36" tires and some mild wheeling and trips in the mud or do I need something stronger?

    It'll hold up good enough for now. If things start to break, you can buy stronger parts (axle shafts, u-joints, etc) but if you really beat on it and trash things out, then you might eventually be better off with a D60.

    thanks again, was kinda worried about running a 36" tire with this axle but from what I'm being told by several places it sounds like I should be OK for what I plan on running, again thanks for all the info
