    I can't see your picture, but what is the wms-wms measurement? What is the axle's BOM #?

    Lots of D70 axles were made that were not for GM, and lots of them were SRW as well as DRW.

    By the looks of the hub it appears to be a Ford offering. Like said by Atho - get a B.O.M. # and it will tell all .

    AFAIK, GM never used a SRW D70. I was simply saying that just because its a D70, doesnt mean its from a GM. Especially since the original poster was clear as mud and I can't see the pic :p:

    dually,

    in fact i JUST now got back to my puter from being across town looking at a 68 F350 dually dump truck, it has a dana 70 under it,
    the guy broke the axle, the pinion is hanging out of the diff housing alot

    its toasted bad,.

    now he has to find another axle for it,
    i guess they arent very good bearing design

    right across the street from the the 350 is another 68 or 69(steel painted white small bar grille) ford its a 4x4 250 high boy, its dana 60 front and rear im sure, i think it can be gotten for 250 or 300 bucks, if it were a chevy then id have had it by now for the rear axle,
    cant find any damn chevy 3/4 or 1 tons,, all gone :/


    hooray for chevy 14 FF's :D

    heh


    good luck

    Its a 6 digit number that will be stamped into one of your axle tubes. Might be hard to find if the axle is crusty. But if you get it, you can run it on the decoder on www.drivetrainsuperstores.com and it will tell you what its from.

    It probably won't be worthwhile to make the swap, the 14 bolt and D70 are basically the same strength.

    GM did offer a SRW Dana 70 in the late eighties/early nineties C/K series trucks IIRC it was a 70-3.

    Nothing wrong with the D70 bearing design, just cause an axle broke on a 38 year old dump truck, doesn't mean it's a POS.

    There might be a metal tag under two of the bolts that hold the diff cover on. If it's there, it should tell the BOM and gear ratio. If there's anothe small metal tag under one of the lower bolts of the diff cover, there might be a powerlok or traklok in there, bonus.
