    I was fortunate enough or unfortunate enough to pick up a
    1974 dana 70 front axle from a dodge fire truck. The weird
    part is that it had a 60 in the rear. Anyway, I was wondering if anyone has ever run one. Is it a boat anchor,
    or does it have brute potential. I have heard about people
    replacing the drum brakes with disc from a 60 by cutting of
    the ball joints and going with ones from a 60. Any info on
    this matter would be greatly appreciated. Thanks everyone.
    Brian.

    Well, I don't know much about it, but as long as you are running tall enough tires that it isn't being a boat anchor, dragging on everything, go for it. Kinda like deuce and a half axles or Rockwell 5 ton Planetaries.

    I think the Dana 70 is a 11/4 ton axle. If you have big tires it will be high enough. I think I've heard its as strong as a 14 bolt

    As far as ground clearance go's I have heard but am not sure
    that a 70 and a 60 use the same diff cover. If that is true
    why would it hang down any more?

    I have a K-5 with Dana 70's front and rear. It was also sporting some 52" Tractor tires.

    Does your blazer have a disc brake front or a drum front.
    What did it come out of. Gears etc. I just wanted to know.
    Thanks,
    Brian

    I have met a guy who runs a 70 in his k5. It's a beast of a truck. Last year I awarded this truck most Dents at the Southern Summer Convention. Here is a link to a pic of his truck http:// www.tennessee4x4.com/et4wd/benjordan.html
    If you look you will notice no windsheild in the truck LOL serious hard core! he did put one in last winter because his girl friend was cold.
    Here is link to the club he runs with. these guys are the big dogs at Tellico. http:// www.tennessee4x4.com/et4wd/

    That 70 you got, in stock form with closed knuckles and drum brakes, is weaker than a late model 60 axleshaft wise. The only benefit you gain is the bigger ring gear (10.5" vs. 9.75") at the cost of weaker axleshafts and u joints. I'd stick with the 60, heck you got enough of em!!!!!
