How do you tell the difference

Is there a visual or figural difference between 10 bolt and 12 bolt 30 spline inner axle shafts?

What about stubs?

I'm trying to determine just what axle sets I have aquired. :confused:
 
Well hell, Dana 44 is what I meant. The difference between 30 spline D44 and 10 bolt axle shafts.
 
The shaft length should be different. The neckdown on the axleshaft is probably a little different too. The best way I know of though is the length of the shaft.

Ooops, there you go thinking again.. :p:

D44's do have 30 splines, as far as I can recall anyway.

Dont know that much about these little axles :p:

but I DOOO know the stubs and joints are the same :D
 
The other way to tell? See if it fits...
Not too hard, I can have the thing down to the stubs in 15 minutes.
 
You may try checking the diameter. I think the 10 shaft is about 1.28 .. and the d44 is over 1.3 .. maybe 1.31 or 1.32 something like that anyway. I know it's not a lot of difference, but may help. :dunno:

Pleeeeeezzzz

The 10 bolt, would be what you just pulled out from under your K5.

Wheres the :kickballs: when you need it! :wink1:



:D
 
That's for 28 spline---1.28". 30 spline 10 bolt and Dana 44 shafts are both 1.31". Only difference is spline cut, really.

COO :thumb: I was wondering about that.. wasn't sure what the 30 spline 10b diameter was. I'm lucky to remember the diameter as it is.. :rolleyes: :doah:

From what I can find the length for the truck axles before 1988 is 31 5/16, only problem the D44 is the same length.

Here's a few pictures, see what you think.

I made this picture years ago and sent it to both Randy's R&P and Stephen at ORD when the big 30-spline 10-bolt debate started:

This is a Dana 44 shortside inner laying next to a 30-spline 10-bolt shortside inner.

As you can see the length is different as the offset of the differential is slightly different between the D44 and 10-bolt. On the longside shafts the D44 is longer than the 10-bolt. Also the seal surface area is completely off between the two types.
 
Eureka! Hey 6.2 would you happen to have the measurements for the short/long D44. At least I'd have the high and low figure.

The D44 shaft looks like it has less of a neckdown and a more pronounced shaft seal base. I think I've got the D44 shafts.

By the way THANKS!
