dana 44 flanged axle housing ID

how can i tell the difference between a 10/19 spline housing and a 30 spline housing. its easy if the axles are installed, but what about when there is just the stripped down housing without brakes, axles, or any internals?

 

Don't hold me to this but, I believe the axle tubes are a larger diameter on the 30 spline flanged units. Also, the absence of the grease fitting at either end of the axle tube would be a clue though, I'm not sure all the 10/19 spline axles had this. I'm sure the build date codes would give it away also, if you can decipher them. I thought there something here about the codes some time ago. Maybe try a search on that.

 

Flanged axle housings were 2 3/4" diameter and tapered were 2 1/2". The tapered axle housings had a round concentric bolt pattern on the housing end and the flanged axle had a sort of flat area on top and non concentric 6 bolt pattern on the housing end.

 

On one of the tubes, the passenger side, I think, there is a 6 digit number, Dana calls it BOM #. If you find this number, a Dana dealer can tell everything that is in the axle.

 

2 3/4 inch tubes, flat area, non concentric bolts, check check check! the grease port made me wonder...

 

Some of the very early CJ flanged D44 axle housings have pressed in grease zerks as seen in pic above.

 

Never saw the zerk before, in a flanged axle. But, i haven't really seem too many of them in the first place. Learn something new everyday.

 

Good info there Ken.

I have the zerks on my 70 flanged 44.

 

None on my '71.

 

I have all 3, a 1970 offset /flanged and also a 1971 offset /flanged CJ Dana 44. Plus a 1972 D44 from intermediate CJ.
The 1970 has 3/16" drive type grease fittings but the 1971 housing tubes do not have grease zerks.
Technically my 1970 axle assembly was built in mid 1969 and the 1971 axle assembly was built in 1970.

Also note: The intermediate CJ with centered carrier flanged D 44 axle tubes (1972-1975) do not have any gease zerks.

 

Breathing life into an old thread here....

My DJ has a DOD of Feb 70.
Dana 44 is centered/flanged
3.73 gears with a trac lok
Has the zerk fittings at the end of the tubes; don't know if they are pressed in or threaded (I'll look today)

I have been thinking of swapping out the trac lok if it's defective and going with a powerlok.

I was wondering if the axle shafts would be 19 or 30 spline.

 

I believe all the flanged axles were 30 spline, at least in out world of JEEPs.

 

All flanged axle assemblies have 30 spline shafts. All Trac Loc's are 30 spline units.
Jeep never installed 30 spline Powr Lok's into any of their jeeps.
You will have to rob an early 60's Chevy pickup with Powr Lok front axle or else remove one from from an I H Scout axle.
They are rather hard to come by.

 

Thanks for confirming that.

There's a 30 spline powerlock for the 3.73 within driving distance of me (ie, no shipping charges) I'm looking at. They say it's set up "snug" which I think is their way of saying aggressive.
