    can't you use these to run stock hummer rims...or does it have to be a D70 from a chevy dually? /forums/images/graemlins/dunno.gif

    if you were going to use hummer rims, i'd say go for it, but you need a D60 front with dually outers to do it.

    I thought that the chevy hd70 was only too wide. A friend has a dana 70 in a dodge dually that looked like the standard width rear axle /forums/images/graemlins/dunno.gif

    There's definitely going to be some measuring involved, but I'd be willing to bet it's wider than a SRW truck axle.

    What year Dodge? If pre-94, I bet it will work for you. A 14BFF will be easier, lighter, and cheaper to add locker/gears.

    The 70HD isn't too wide, that's what I have for my Burb.
    It measured out just fine for running the Hummer beadlocks.

    It's not too wide if you use hummer wheels.If you use the standard wheel it will be too wide. A friend had a hd70 on a dodge with 44" boggers on 15"x14" wheels & 3 1/2" bs and from outside-outside they measured over 104". Not street legal in Alabama /forums/images/graemlins/eek.gif

    i measured it, its the same width from baking plate to baking plate as my 10 bolt. I can get new axles and hub assemblies for it to make the track width shorter

    Since you've already looked into bearing hubs and axles you probably know this but...

    Don't use the brake backing plates when measuring it for vehicle fitment. The backing plates can have a built in offset depending on the brake shoe width (which can vary depending on application). The wheel mounting surface on the bearing hub is the preferred measuring point.

    I am replacing my 14FF with a Dana 70 from a 1975 W350 Dodge Dually and the WMS is real close to a GM Van width SRW 14FF. Do take measurements instead of peoples word - not all Dually axles are the super wide versions.

    I re-measured from the ends of the axles and it is 5 in wider that a 14ff. plus one of the hub assem. came apart and ruined the axle tube... so idont think ill use it. What about a 14sf if im only going to run 37 or 38 in tires? /forums/images/graemlins/thinking.gif

    14 bolt SF will be fine. I beat on mine with 38.5 Swampers and it never broke.

    I'd suggest a 14 FF if you can find one cheap though, that's what I run now.
