What axle?
I have been searching both google and here for this answer. I have axle code 39 and I can find that this is an "open" 3.55 ratio, but I cannot find what this axle is (i.e. Dana 60, Dana 70, Ford, etc).
Does anyone know what the make and model of axle 39 is?
Thanks!

The Dana axles have the model number cast into the outside of the case, usually in really big numbers. So if you have a Dana it'll have a "44", "60", or "70" somewhere on it (or "50" for a front diff).
The Ford 9" doesn't have a cover bolted on the back. Instead it has the carrier bolted in from the front. So it looks a lot different from any of the others. It was used in half tons, so you don't have that one.
I don't know anything especially distinctive about the Ford 8.8" except that it looks pretty small compared to most of the others and it doesn't look like a 9" at all. Again, only used in half tons and smaller.
The Sterling 10.25" is pretty massive and doesn't have a "60" or "70" cast into it.
I could be wrong, but I think that pretty much covers the axles used in our years of Ford trucks.

Additionally, you can tell if you have a full float of semi float axle by the hubs, they stick out from the bolt circle on the full float (like on the front) and are flush on the semi float (IIRC). Full floats came on the HD, semi on the LD.

diesels only came with the sterling 10.25 full floating axle. the semi floater was a light duty truck thing, and the diesel engine was no an option on them .

Thanks, it is definitely full floating, that was part of why I wanted a 250 to begin with, just wasn't having any luck finding which axle specifically it was. Wanting to change the fluid soon, and seems like there is some variation on how much is needed depending on which diff it is.
Thanks!

get 4 quarts of gear oil.
pop the rear cover loose and drain rear.
clean the cover and diff housing with a degreaser solvent, making sure it is clean and dry.
apply a thin even coat of silicone to the cover and put it back on.
fill rear till gear oil starts to come out fill hole. proper fluid level is to the fill hole.
