What are you smoking...where did the D70 come into this?
Dodge had a hybrid d44/d60. I have seen one with my own two beady little eyes. It was in a 87 dodge truck...3/4 ton. I stated it was "similar to a Ford D50", not that it was a D50. Guess you didn't catch that
The part I caught was when you said it was similar
to a Dana 50 and then went on to describe it as having a Dana 44 center and Dana 60 outers. This isn't similar a Dana 50 at all. A Dana 50 is very similar to a Dana 44HD but has a bigger ring and pinion set then the '44, but that set isn't no where near the same as a Dana 60 gear set. Anotherwords a Dana 60-ish center and Dana 44 outers, opposite of what you discribed.
I don't know what hybrid Dana 44 you were looking at, unless the axle in question was some custom one off axle or perhaps a late model axle that appears to have bigger outers due to the fact that the ball joints were spaced out making it look like it had Dana 60 outers.
And it isn't even a Ford version...guess the only ones who can have a D50 (or something not D44 or D60) is Ford??
Exactly, neither Chebby or Dodge ever spec'ed out a Dana 50 for use in their trucks. This was a Furd exclusive. It was Furd which spec'ed out a new Dana 44 but with a larger ring and pinion set. Dana built the axle and named it the Dana 50. The first Dana 50s were actually third members for the Twin Traction Beam axles, later they became solid axles when Furd discontinued the TTB. The aftermarket picked up on this axle quickly.
Now it's possible to swap in a Dana 50 but if it's from a Furd, then the pumpkin will be on the driver's side. You didn't mention which side the pumpkin is on. The only other source for a Dana 50 is from the aftermarket. While it's possible, I don't think it likely because aftermarket Dana 50s aren't cheap and if strength is an issue, they'd be better off swapping in a more common Dana 60
I love you people who think you know everything...it is not a perfect world as you must believe you live in. I know there is a lot more out there that I don't know, but I know what I have seen and looked at. Just because you have never seen one must mean they can't exist
I do know everything and if I never see it then it doesn't exist. I wonder how you got to know me so well from one post?
Yes I know anything is possible as there are many different versions of the Dana 44. It's also possible that the axle you saw isn't a Dana axle at all. It can be a rare GM / NAPCO axle from the late 50s, maybe a Furd / Marmon-Herrington axle or even an old Dana-Spicer military axle.
And just for the record...the truck is sitting in a yard in Gallup, NM...it is a former forest service truck, puke green in color...so you can go look at a D44/D60 hybrid for yourself.
I haven't been thru Gallup in along time and I'm not likely to go thru there anytime soon. I'd love to see this hybrid axle and if you have a camera, you can post a pic and prove me wrong.
I'm still trying to see where you got a D70 from any of this since the original post was asking about D44 and D44HD similarities/differences.
I brought up the Dana 70 not as a result of the original topic, but as a response to your
Ohh, wait a minute...you musta figured since I said I had three drum braked versions (OF THE D44HD) that I was speaking of the hybrid...ok, I can see that. And don't tell me there wasn't a drummed version of the D44HD in 1974...I have 3 of them...and they are flattop open knuckled versions too. And FYI, the D70 has decent sized axleshafts (35 spline inners/21 spline outers), it is in fact the tracta joints in the steering knuckle that make them weak.
Considering that you described an axle with a Dana 44 center and Dana 60 outers, and that I mentioned that it doesn't sound like a Dana 50 has me to believe that it could have been another production axle. This brings up the Dana 70. But it still can't be described with having a Dana 44 center and Dana 60 outers. So who knows what you saw?
Since you bring up the fact that this truck is an ex-Forest service truck leads me to believe that the axle isn't some kind of a hybrid simply because government agencys tend to spec out the most bare bones, basic truck, the tax payers can buy. Unique parts tend to cost more and thats not likely in a government truck. I won't deny that it could have been retired and later modified.
As for the drum brakes I didn't bring that up. You did and I didn't disagree. I know those exist.
Prove me wrong...I can take it
