81 f250 rh slip joint
Hey guys. Hope this is the right spot to ask. Tried searching some but connection is so slow takes forever and found nothing. 1981 f250 with TTB? front axle. (not solid) It has 9/16 lug studs if that matters. It is an 8700 GVW I believe. The heavier one when you buy parts. Ok the right hand axle shaft has a slip yoke in it. It is stripped out. Is there anywhere to find a replacement besides salvage yards that are nearly as bad as the one I have? I am a machinist so even if I just found the male and female ends of the yoke I could rebuild the axle shaft. Any advice apreciated. This forum has always helped me out before. One more time guys!

The proper term here is axle drive-shaft, even though it performs the same tasks as a standard axle-shaft. The only differences are like what you found, U joints and slip-yokes that allow for the articulation of the right hand wheel.
Have you check Bronco Graveyard yet?
They have some TTB parts.

This slip yoke fits 84 to 87 F250's with the Dana 44. I don't know if it would fit your 81. Someone is going to have to find a part number...

I did find that slip yoke on bronco graveyard but didn't see my year and did not see a pic so was unsure exactly what it would be (just a yoke or the inner 2 pieces of the 4 piece axle shaft) It may be a good place to do some digging. I figured as many of those old Fords as there were/are runing around someone would know exactly where to get parts. Thank you for your help. I will pull the shaft and see if I find any numbers to research.

On the passenger side of the differential housing, do you see three bolts? If so, you have the bolt in style stub shaft used from 1980-1982. This means that you have three years of axle stubs to look for that will fit your truck if you decide to replace the entire stub shaft.
The 1983-1996 trucks use a C-clip inside the differential housing instead of the bolted retainer to hold the stub shaft in place. You can use the outer half of the stub shaft, however you would have to remove the differential to get to the c-clip that holds the stub shaft assembly in place in order to remove the stub shaft assembly.
However, you can just swap the outer ends of the stub shaft, since a U-joint connects the inner half of the outer shaft, and it's your outer shaft that contains the female slip yoke splines that are damaged. The outer sections of the stub shaft are the same, regardless of whether or not the other half bolts in, or is held in by a c-clip.

I had this happen to me, and you have to get the yoke(the female part) and a new axle shaft(the whole shaft). I got my parts from Ford, but that was many years ago. You can't weld a new male spline piece on like you do for a regular driveshaft, you have to get the whole axle that goes out to the pass side u-joint.
Your axle assembly is going to be a dana 44hd ttb (standard issue) or could be the heavier axle, the dana 50(looks just like the 44hd only has some heavier parts on it).

The 1983-1996 trucks use a C-clip inside the differential housing instead of the bolted retainer to hold the stub shaft in place. You can always swap to the newer style differential housing and stub shaft. But you'd have to buy the differential housing and have it rebuilt if it isn't in good shape.
I would personally shoot for swapping the differential, because then you would have 15 years of axle shafts instead of 3 years.

Thanks for the help.

The long axle shaft going out to the outer most joint has the male splines on it. The female splines are in the yoke, which has a joint on it and a very short shaft that enters the pumpkin.
I am not sure why you would need to swap out or get a new the short axle stub coming out of the pumpkin, the yoke can be swapped when the u-joint is taken apart.

Edited my info for accuracy.

Thanks for everyone's help. I aquired an axle shaft from an 85 model at a slavage yard. Swapped the inner most portion (that penetrates the differential) at the u-joint and used the rest of the axle. The reason being mine was 3 bolt style and the donor axle was clip style. Easy peasy back in buisness. Ford forum is awesome!
