    Just like the title says. Its a one ton Dodge van 14 bolt.

    The 14BFF is a GM axle. They were not OEM under anything else. I would guess that a 1 ton Dodge van would have a Dana 60 or Dana 70. /forums/images/graemlins/thinking.gif /forums/images/graemlins/deal.gif /forums/images/graemlins/waytogo.gif

    Dodge never used the 14 bolt from the factory so it must be swapped in. The only way you'll know on that axle is to break out the measuring tape.

    I just found it this morning. I don't think its been swapped. I just saw the bolts on the outside of the axle shaft and bent down to look under it and it resembled the shape of a 14 bolt. I didn't actually count them. So then maybe its a dana 70? This would work right? What would be involved in the swap? Worth it? /forums/images/graemlins/thinking.gif

    This USED to be true. GM sold their part of the axle business and the new company AAM does sell to DaimlerChrysler now. Whats even more perplexing is that there are now several styles: the tried and true 14bff and 14bsf, and some new ones under Silverados and even mopars, a larger one and a smaller one. There is even a smaller 14 bolt front now if you find a wrecked 2003-2004 dodge 1 ton. And these all come from SAME place. But this one in question is probably a DANA.

    It looks like a early 80s van.

    yes it will work but before you install it I would shave the lip off the bottom.

    also a good locker might be hard to find. they are out there but very spendy I would consider welding it if its a trail rig that should save you some money.

    is there a reason you dont want a 14BFF out of a pickup. it just seems like it would be a lot easier and cheaper

    if you are dead set on the D70, check to see what the WMS to WMS is, availibility of lockers, cost of bearings and brake work, and supply of axle shafts.

    id go for a 14B, just my $.02

    Have not been able to find a 14bolt single wheel locally, can only find dual wheel 14bolts.

    If its wide enough for ya ,you can make it work.If you can get a BOM number off of it you will have alot easier time getting parts.Pretty much no matter what 70 version it is (HD or U,one or two piece carrier,either pinion offset) Detroits are available.ARBs are also available depending on model.And the best part,you can get ratios down to 7.17.Make sure its a Dana 70 and not a Dana 60 or 61.In my search for a 70 I found alot of Dana 60s and 61s in Dodge and Ford 1 ton vans.Easiest way to tell if ya cant tell is to pull one of the shafts.If its a 70 it will be 1.5" diameter 35 spline (and I think there are also some 32 spline models also)

    I dont know the actual year or aplication of my Dana 70 but,it was only $50 and in ok condition.It also has no BOM number either but that was not the end of the world.I replaced all the wheel bearings and races,wheel seals,brake shoes,both wheel cylinders,all 16 wheel studs,and one drum and it came out to about $300.A Detroit is $640,master instal kit is $110,and 5.86s were $160.

    Any more questions /forums/images/graemlins/tongue.gif
