D44 vs 10b axle shafts

[Muddytazz]

I'm having a brain fart

Isn't there a different in axle shafts? Will both the inner and outer shafts swap over to each other?

I was corrected on this years ago. Outer stubs are the same. Inner shafts are different. The splines are cut at different pressure angles....



**EDIT: I am referring to 30 spline 10 bolts

 

[85mudblazin]

yep stubs and joints are the same

 

[GMCLegacy]

10 bolts have 28 spline inner shaft, D44s are 30 spline

You can put a D44 30 spl. in a 10B 30 spl but not the other way around. It's not right, the angles are different but it fits and works. I think it takes a combo of jeep and ford D44 inners.

GM Dana 44 and Corp 10 bolt have different length inner shafts.

GM Dana 44 and Corp 10 bolt have different length inner shafts.

Correct. I have pictures of a GM Dana 44 inner vs. a 30-spline 10-bolt inner. The total length is different, the machined seal surface is completely off, and the splines have a different pressure angle. As Stephen mentioned, you can find Dana 44 inner shafts that are "close enough" in length to use but they are not a GM factory application.
