Front axle ID
Judging by the hub I am thinking this is (unfortunately) a Dana 44 but wanted to double check with the experts to make sure. It is a TTB in an '89 F250HD with a 460, c6 and 10.25 sterling rear.

I've heard theories on how Ford decided to use which axle where in F-250s, but there usually seems to be someone who has a truck that doesn't fit whatever theory is being proposed. Personally I think it had something to do with sun spots...

years ago at the body shop we had 2 F50 4X4's one serial number apart. they followed each other down the line. 351W E4OD trans. reg cab 8 foot bed. one black, one red. the black one was in front, it got a D-44. the red one directly behind it got a D-50. same identical trucks, except for the front axle.
i think what axle the truck got was determined by what part the guy in the warehouse decided to put on the assembly line feed belt.

The most obvious difference between the Dana 44 and the Dana 50 is the size of the hub. If you look at the first picture below (from the first post above) you can see that the Dana 44 hub leaves a pretty big gap between the hub and the center hole in an F-250 wheel. Also there's a step where the hub diameter is larger than the chrome locking hub assembly.
On the other hand, the Dana 50 hub almost fills the hole in the center of the wheel, and the locking hub assembly is about the same size. You can kind of see that in the bottom picture. (The middle picture is a Dana 44 in a '71 Bronco, sorry, it's attached to the bottom picture)
