    I just found this

    1977-PREVIOUS F350, F250 snowfighter: low pinion dana 60, very weak.....

    1978-1979 F350, F250 snowfighter: high pinion dana 60, kingpins, 35 spline outters, 30 spline inners, internally splined lockout hubs

    1980-1985 F350/F250: high pinion TTB dana 50

    1986-1991 F350: solid high pinion dana 60, king pins, 35 spline outers, 30 spline inners, internally splined lockout hubs, different spring spacing that 78/79 axle

    1986-1989 F250: TTB dana 44HD/ TTB dana 50, both high pinion

    1991-1997 F350: solid dana 50/solid dana 60, 50 hase smaller ring gear and axle shafts than 60

    1990-1997 F250: TTB dana 50, high pinion

    1999-2008 F250: solid dana 60, solid dana 50, both high pinion, metric pattern

    id say a 97 f-350 because its got the dana 60 and you can service the wheel bearings vs changing out the hub assembly.

    All of the Super Duty's have straight axles (from 99- current). Are you thinking about the spring change that happened in 05?
    99-04 have front leaf
    05 - current have coils

    I agree with 02 powerstroke. Didn't they do that till mid 90's on the 3/4 tons? I am not real sure for that.

    so there were only a few 3/4 ton f250s in the 90's that had the ttb. For instance my 97 f250 heavy duty powerstroke( as the badges say) came with the ttb, which was also one of the first things to go, it now sits as it should with a dana 60 up front. however my 90 f250 gasser 4 wheel drive, has a ttb, thats just a driver, not for plowing. so it will stay that way. as for now, all of the ford 4 wheel drives use straight axles. diesel or not.

    F-250 4 wheel drives had twin traction beam front axles in them from 1980 until 1999.
    F-350 4 wheel drives have had a solid front axle from mid year 1986 to present.

    I'm new to plowsite but have a lot of rep on lawnsite! I have a southern Rust free 01 powerstoke 7.3 quadcab 4x4 auto f250 for sale. It has a solid front axle(factory dana 60). The truck is 100 percent tight. My lawnsite-plowsite price is 12k. A bit more if I replace the tires.

    actually, the 01 F250 has a Dana 50 solid axle in it. they did not start using the Dana 60 in the front of the 250's till mid year 02

    Are we talking about a straight reverse cut axle? Like a 60? I thought all F-350's had them?

    I have a question about this, since many of you seem to know a lot about this. I have a 1999 F350 that had the dana 50 in it. I am replacing it within the next few days with a Dana 60. (It can be done and the two axles are identical for mounting to the truck). I am doing this because the dana 50 needed ring gears and a few other things and I found this axle and it is just much much easier.

    But my question is whether or not the Dana 50 and Dana 60 have the same Rotors, hubs wheel bearing assemblies?? I am thinking that they do just becuase my dad has a 2002 F250 with the dana 50, but halfway through the year they switched to a Dana 60, but yet whenever he calls an autoparts store and needs any of those parts, the store never needs to know which axle is in it.. So i am thinking that the parts are all the same?

    Not sure if it is true but I have heard that the Dana 50 and dana 60 are identicle on the outside but only bigger on the inside.

    Any ideas?

    the difference on the brake parts is that the SRW trucks have 13 inch rotors, and the DRW trucks have 13.5 inch rotors.
    but the parts books don't show this breakdown, they only show the two sizes. so you have to measure the rotors to get the proper parts.

    then to screw things up even more, starting in 05, the rotor sizes jumped to 14 and 14.5

    With out going back through a huge pile of books and paper work, I cant quote the exact years on the changes. I believe it was the early 80s when the 150s went to the TIB suspensions. In the mid to late 80s they started making the 250s with iether/or, You could get it with a solid or twin beam. One thing most people don't realize is though, the F250 with the twin I beam had the same axle housing as the F-150. It just had heavier duty components, such as stronger axle shafts and the works. The heavier duty F250s staid with the solid axle. As far as the F-350s I've never seen a one ton in a four wheel drive that didn't have a solid front axle.

    see post #11
    no F-250 made between 1980 and 1999 had a strait axle from the factory.
    some came with the D-44 ifs and some with the D-50 ifs. but none were made with a D-60 monobeam. all F-350's made between 1980 and 1985came with the ifs. no monobeam front axle was offered from the factory in these trucks.
