Axle ID help

I think this axle is a Dana 44 or possibly a 60.
Any ideas? Havent taken any numbers off it yet.





Found a rough guide here:
Axle Identification Chart

I had to swap this in a long time ago when the 9" outer bearings crapped out on me. It fit, and bolted right in, didnt care at that time. Wish I still had the 9" though.

It's not a Dana 60, only used in F250's with 8 lug wheels on a 6.50" bolt circle pattern.

So, it's either a Dana 44 or a Dana 60.2 or Dana 60.3. All: 5 lug wheels on a 5.50" bolt circle pattern.

Dana 60.2's (optional 1964/66 F100) & Dana 60.3 (optional 1966/69 F100) have Limited Slip as do 1961/68 optional Dana 44's.

1961/67 & some 1968 F100's: Limited Slip was not available with the 9 inch.

The rear axle's ID tag is gone, so the only way to ID it is with the inspection cover gasket.

Dana 44's use a different inspection cover & gasket than Dana 60.2's & 3's (all use 10 bolts to retain the cover to the housing).

There may be numbers stamped on the axle tubes, but the axle's ID tag is missing. It was under one of the bolts that retain the cover to the housing. I looked, it's MIA

Look at my other post, I added some ID info.

Didnt find a single number on the rear end today after I got the box off. Im assuming the 44 has smaller internals than a 60.

Ive searched high and low and haven't found any reliable info about those casting numbers.

I will be popping the cover in a few weeks. I need to make sure Im right, but the 60 has a 9-3/4" ring gear, and the 44 has a 8 1/2" rear gear? Im assuming if its a 60.2 or 60.3 it will take regular D60 gears? In that case a 3.55 ratio is the highest I can probably go, although from what I have read, most of the 60.2s and 60.3s were generally limited slip rear ends.

Did you get those numbers off of the right hand side of the axle? that is where your ID numbers on A Dana Axle will be found... it took quite a bit of Brake cleaner, and pressure washing to finally see it on my truck. it is a rather lengthy number!

On the right hand side you will usually find a date code followed By the BOM (Bill Of Material) Number... that is the number that the Gear and transmission shops will use to ID your Axle it will face the rear of the truck It will ,most likely take a lot of cleaning, as they tend to rust over with age. The numbers are stamped in pretty deeply though so be diligent and thorough! Most Likely it is a 6 digit number followed by a single digit, or similar to that format! I am attaching an ID link

Dana inspection cover bolt thread size.

Dana 44: 5/16" -18 x 5/8"

Dana 60; 60.2; 60.3: 3/8" -16 x 5/8"

The internal parts are different between Dana 60 vs 60.2 & 60.3.

Jet: I took those numbers off of the top of the case on the driver side in the webbing. Thats why I was never able to see them before, because it was too dirty. Photo below. I was never able to find any stampings on the axle. I will take the wire wheel to the axle next weekend and see if I can dig out the BOM.


Bill: The 44 has a smaller diameter bolt for the inspection cover? 5/16 vs. 3/8? Interesting. I will take a look at that next weekend.
