Need help to ID an OEM Axle

[jreb10]

I tried to order a used OEM Subaru front axle shaft for my
1998 AT Legacy wagon. I messed up, and the axle I received did not fit. I
solved the immediate problem by rebooting my original axle.

 

Now I need to figure out what axle I bought, so I can sell
it to someone who can use it. I did a lot of searching for an answer but remain confused.

 

Supposedly it came off of a 1994 Legacy, AWD with manual
transmission. It is definitely an OEM axle, made by NTN, with the green paint.

 

On the transmission side there is stamped “DOJ   82 AC  
NTN”. Inside the tranny end are 23 splines.

 

If anyone can tell me what I have I would be very happy.

you've left out what may be the most helpful bit of information - ***why*** didn't it work? 

length, style, spline count, OD...??

 

i've seen damaged splines where an axle wouldn't slide onto a trans stub or into a knuckle.   it's possible the axle would work but is damaged. 

 

some early EJ axles from FWD versions have a different spline count on the inner joint.    you can google which ones that is.  people used to like them for transmission converstions or older gen conversions which has the same spline count on the trans side.  that would be my first guess - they assumed it was the same but it's different.

spline count , compressed free-length, and tone ring if applicable would be the 3 main factors.

EJ axle with 23-spline inner is one option. '93-'94 FWD 5MT Impreza 1.8.

Thanks to all. Now that I have recovered my Photobucket access I can post some much needed photos. I should also add that I discovered the axle to be different when I inspected it side-by-side the old axle. I confirmed that the spline count of 23 on the transmission stub end is not right for me. It went in too easily (diameter too large) and did not engage the stub splines. I concluded I need a 25 spline count, and instead rebooted my old axle.
