Dana 44 Spline Count... ??
Hey all!
Does anyone know if the splines are the same from a 1979 Dana 44 solid axle to a 1994 Dana 44 TTB axle ?
I am trying to re-use the '94 drivers side axle shaft for rebuilding a '79 axle.
I know the passenger side wont work because of the extra TTB joint. But hoping that some of this stuff will convert over.
What about the carrier, bearings, ring & pinion?
Is anything the same? If not, then why is the TTB even called a Dana 44? Why didn't they just give it a different name?
Thanks!

Spline counts are the same, and I'm sure spline pitch is also the same, but the length is gonna be way different. IIRC even the stubs are different lengths, but I could be wrong.
They call it a D44 because all of the following are the same:
1.spline count
2.axle shaft dia
3.carriers
4.carrier bearings
5.ring and pinion
6.pinion bearings
7.lockouts
8.wheel bearings
9.ujoints
10.yokes
11.pinion nuts
to name a few

Thank you so much for the info!!
The most important parts I need to know about are:
Spindle, caliper support, rotor, & hub
Are all of these '94 parts compatible with the '79 axle?
If my thinking is correct...
The bolt pattern off the knuckle is the same on both axles then the spindle and everything out from it on the 1994 axle can be installed on the 1979 axle, right?
Then I can use all of the 'knuckle-out' parts off of my 1994 axle to rebuild my 1979 axle, right?
It all boils down to the knuckle/spindle bolt pattern and splines, if they match up then I am set.
Anyone know for sure?

I'm 99% sure none of that will work. The 78/9 spindles are 5 bolt while the TTB is 6 bolt. And you can't put the 78/9 knuckles on the TTB arms because the ball joint spacing is different.
