D44 build problems pt 2

rideabike · Mar 7, 2005

ok, the d44 i am building came with 3.07s
i am putting either 4.10 or 4.56 in
i bought a new case, 3.92 and up
i bought new bearings for the case
the new bearings fit the case, but not the axle
the old bearings, on the old case fit the old case and axle, but not the new case

wth is going on?! desparately needing some help here

*the axle is a 79, out of a k10, no BOM or any other info is stamped anywhere on the axle

Does the cover of your 44 look like this?

That's a 10 bolt.

In your other thread, Brett posted that a 79 had a 10 bolt front, not a 44.

How's the GM passenger side diff working for you?

My thought exactly.

Edit: If you Sierra chapter youngin's keep getting smarter, we're going to need to get some new youngins'.

Yeah, the dana 44 and 60 both have some straight edged sides (diff cover). The 10 bolt is a very common Chevy diff mostly used in the front, but also in the rear of later model K5's. It's know as the "Poor Man's dana 44". I wouldn't bother much with it, the dana 44 is a better all around axle. If you have the parts and got it cheap what the heck. Click on this link for a xj dana 44 pic and desc. Obviously you have a front axle, so it will not look like this exactly, just look at the diff shape, does it look like this or the pic that Phil posted (round cover)???

That was a good find by him. Wish I was that lucky with finding parts. It looks like he has a truss on that 44. Is that a good idea with the 44? Ive never seen one bend before, at least not on Cherokees.

It's a little overkill, but I would rather overbuild than underbuild. Breaking down offroad isn't run. Yeah, a free xj 44 is hard to beat. Well finding 1 at pnp for $135 isn't too bad either. :laugh3:

Come to Colorado, pull n save = $62.99 out the door............. :laugh3:

If a D44 is that good does the obvious factor of more is better apply? D60?
Is the D60 a bolt in or does it require narrowing / spring perches / etc...

i have a d44, it is not a 10 bolt

anyone have any useful info?

"How's the GM passenger side diff working for you?"

its working, or rather will be working great once i get the bearing problem figured out, great

a passenger drop 241 works real damn well with a passenger side diff

but really, anyone got any ideas?

What are the numbers on the race and the bearing?

The race should be 25523 and the bearing should be 25590. Those are NTN numbers, but they cross to Timken.

Both are for a 30 spline Dana 44.

and what if it is something other than 30 spline??

ie 28 spline???

You don't have a dana 44.

D44:

this is what the pumpkin looks like

im not tryin to be a dick or makin stuff up here, im just really dang confused

CW · Mar 8, 2005

I am fairly certain that all dana 44's are 30 spline. Here is some info you might be able to use.

rideabike · Mar 8, 2005

that looks correct, however, i have a d44 housing...

is there anyway someone crammed something else in there? used different tubes on the pumpkin?!

the part number listed above for the race does not fit the race/bearing seat

im going crazy here

I think all newer 44's were 30 spline while some older ones (read OLD) were 18 or 20 spline

CW · Mar 8, 2005

Yeah but he said '79. And the 79 k10's came with a 10bolt.

BrettM · Mar 8, 2005

so assuming it really is a D44 housing, I'm pretty certain there is no way to get a 10bolt carrier to work in it, but could possible just the side-gears fit, so someone put 28 spline 10bolt sidegears and shafts in?

CW · Mar 8, 2005

I think we need pics of the axle to really be able to help. If it is a 44/10bolt hybrid someone was really cheap or board.
