i have a 1985 ford f-250 and it has the 4.9 300. call me dumb but i am not good with axles and i could use help identifying these. these pictures probably wont help but i figured id give it a shot! thanks.

 

Since you have a f250, is it a regular cab? If so, the front axle is most likely a dana 44hd ttb. You can also verify this by looking at the hubs. If they are the same size you are used to seeing on the f150's then it's definitely the dana 44hd. There were supposedly a very few regular cab f250's with the dana 50, and all the extended cab f250's had the dana 50. It has 4x4 hubs that are a little larger in diameter.

Do you have the long things that stick out of the center of the rear wheels in the back? The round thing with the little bolts? If so, you have a regular f250 full floating axle. I can't see in the pictures, but if you have no oil fill plug in the back cover, then it's a sterling/Ford axle. If it has a oil fill plug in the rear cover, then it's a dana 60 rear axle.

If you do not have the round thing that sticks way out in the center of the rear wheels, then you have a light duty f250 semi-float axle in the back.

 

Rear axle is a Sterling 10.25. I believe that all Dana 50s have the number 50 cast into the bottom of the third member, but there is no way to tell what front axle you have from the picture provided

 

The front looks like a D50 bc it has the shorter TTB arms.

 

And how can I tell if they are full or semi float?

 

The rear is a full-float if it sticks out from the center of the wheel for a few inches, that protrusion has I believe 8 bolts on it that hold the axle on.

Like this:





The semi-floating axle doesn't have that protrusion.

On a different topic, your PMs aren't enabled yet (you're still too new) so I'll say this in public... you filled out your Facebook information incorrectly.

See the blue FB icon in the top-right of your posts? Clicking that is supposed to take one to your publicly-available FP page.

In the FB field in the User CP, it is asking for your FB Username. You can set this up in your FB Prefs, go to General Account Settings and it's the second field on that page, something like www dot facebook dot com/username. There is a link to the right where you can edit that, but what you put there needs to match what you enter in FTE User CP.

Hope this is understandable.

 

F250s use the same length beams, whether it has the Dana 44 or Dana 50.

If its full float, it will have a hub similair to the one in the picture in the middle of the brake drum.

 

I was thinking the D44 ttb had longer arms, but I looked it up and see you are right. The 44HD TTB is short as well.
