Numerical values? DANAS??

[junior3382]

This was taken from 4wheeloffroad.com. similar information to the previous chart I posted, but some missing details. This is the closest I have seen yet to indentification of these axles, but still not exactly what answers my question. Camino, I hope this helps. If I had the time myself, I would try to figure this out too. Let me know what else you may need for info, and I can try to look. Sometimes with several eyes looking, there is less that will be missed.

there was more on the page then what actually showed up here, not sure what happened. Here is the link.....

Axle/Differential Identification at http://www.4wheelnoffroad.com/


And here is another on, so much info here ion several different pages....

Dana 44 Axle Article and Resource Directory

Those numbers only deal with the "BOM" this is simply the bill of materialsIt will identify the year, series, axle tube thickness etc.
Something that we did not discuss, is that all of the Dana axles had different wall thicknesses, even from the same series axle.

could mean more also

I disagree... the Dana 44 comes in several different sizes and widths... You can find a Dana 44 in a mid size Jeep, or you can find a 44 in a full size 3/4 ton truck.. I don't know what the numbers are, but I am pretty sure it's not anything to do with weight or width (in inches as stated above).

*doh* EDIT: I didn't see the other 3 pages on this topic I thought there was only 1 page Time to go back and read

Okay, I have looked enough. I will come back to this subject later as it does bother me to have a question unasnwered. But from what I have been able to gather, there is no definitive logic behind the numbers on these. As long as a person knows what will work, then so be it. I am sure I will find it eventually, either a definite yes or no to the values, but as for now, I am moving on. Watch, this thread will pop up again in like a year, and the answer was so simple....LOL. Meanwhile, if anyone does find it, let me know.

i've skimmed through it and found nothing. with a couple layoffs at work and a lot of school stuff i've not been able to much searchin though

[junior3382]

Could the numbers relate to the original production year?

[chevyguy]

I always thought it was the inner axle tube size in MMs. Never took the time to find out otherwise. Jst figured if it wasnt, It was just a production identification number (series) given by Dana. I know how to id them, Just not real sure why they chose that particular number. Too busy to chase it donw. hope you find it.
