i have a 81 F250 with a 44 TTB with a busted shaft and was wondering what other axles from what years will bolt right in?
i have a spare TTB to throw in for now until i can get a dana 60 but was wondering what years interchange

This should help go to 2bigbroncos.com then click on Technical White papers to the D60 swap.

Hope it helps:D

If you have a F250 you should have a D50 TTB it's a H/D D44 with 8 lugs. So if it's a D50 any from 80-86 will bolt in prob the later ones as well but I'm not 100% sure

So are talking the whole TTB or 3rd member?? Eather way you should be able to just swap them out.

For 1980 the Dana 50 only came in a F350. No F250's ever got a Dana 50. I think is true for 80-86 but only have documentation to 1980.

ok, the dana 44 H/D ttb came in all f-250s except the ones with a heavy duty tag on them, they had the dana 50, as far as i know, the f-350s from 80 to 86 had the dana 50, but i am not sure on this, noone wants these model trucks, so i stay way away!

1980-1996 F-250 and 1980-1985 F-350's can have either the TTB D44HD or the TTB D50.

Front rating

D44HD = 3800 lbs
D50 = 4600 lbs

Look at the door tag for the weight rating. If you're looking at just the axle, no other info available- D44HD will have internal snap rings on the axle shaft u-joints and the D50 will have external snap rings as well as D60 size hub lockouts.

As for what year axle shaft will swap, I think it's only 1980-1982 that has the bolt-in stub shaft you have. If you want to swap to the slide-in style with the c-clip, you'll have to swap the third member out for a newer one.
