I have a 79 ford f150 custom my font axel Is a dana 44 I have gear oil leaking out of both ends of my axels any ideas what seal this could be and part numbers for these seal just trying to find out and if anyone knows where I can find a break Down of all the seal in the axel and where they go

 

That's a helluva run-on sentence.

I would visit Dana-Spicer's online tech manuals for part numbers applicable to the BOM of your axle. Then I would contact a reputable vendor, tell them the parts I need and buy them.

Then I would replace the seals and any other consumable parts in the due course of the work.

Great time to replace wheel bearing as well as you will have everything off.

 

Check your axle vent hose, could be plugged and causing seals to leak, If front axle does not get used much could be leaking because of that. Lock hubs in and drive for a while, sometimes it will reseat the seals (SOMETIMES) also make sure not overfull. I have got by with this before to extend time before teardown.
