jasonkaye Posted November 27, 2016 Share Posted November 27, 2016 Hey all, I'm in the process of cleaning, re-greasing and re-booting the two front driveaxles on my 1991 Loyale 4WD EA82 manual transmission. I pulled those axles today - one axle might be OEM, and the other axle is marked with a "remanufactured" sticker. I also pulled two front driveaxles from my parts car - a 1990 Loyale 4WD EA82 manual transmission. As I disassembled the "inner CV joints" of all the axles (also called "DOJ's" by the How To Keep Your Subaru Alive manual) I noticed something very strange - the inner race of the DOJ's on the axles I pulled from the 1990 EA82 have 32 splines! The DOJ cups are a bit bigger, too. As far as I understand, the axles for both of these vehicles should be 23-spline. Two questions: 1. Any ideas as to why/how those DOJ's are 32 splines? The original and only prior owner of that vehicle was an elderly person who didn't drive it much, so I doubt they did any sort of transmission conversion. 2. How would I modify my current EA82 (with 23-spline axles) to fit the 32-splines axles? (I'm asking more out of curiosity; I imagine this would be impractical to the point of silliness. Eager to solve the mystery! Jason Quote Link to comment Share on other sites More sharing options...
Loyale 2.7 Turbo Posted November 27, 2016 Share Posted November 27, 2016 ... the inner race of the DOJ's on the axles I pulled from the 1990 EA82 have 32 splines! The DOJ cups are a bit bigger, too. As far as I understand, the axles for both of these vehicles should be 23-spline ... Could you Please, share Photos of those DOJ cups with 32 Splines? So we could better figure out what's going on in your Subie. Kind Regards. Quote Link to comment Share on other sites More sharing options...

jasonkaye Posted November 27, 2016 Author Share Posted November 27, 2016 UPDATE: One mystery solved; another mystery born. One mystery solved: The first mystery of the "32-spline axles" on the 1990 EA82 has been solved by me being an idiot - the axles are not 32-spline. The DOJ axle cups are all indeed for 23-spline axles; that is, 23 splines where the DOJ connects to the transmission stub shaft. However, the inner race of the DOJ's on the axles I pulled from the 1990 EA82 do have 32 splines. This spline connects both parts of the DOJ inside the axle cup. This appears to be a variation in the manufacturing of the DOJ innards; this variation does not affect how the DOJ connects to the transmission. Another mystery born: The two pictures below pose a new mystery. You'll see that of the four front axles I pulled from similar vehicles, three of them require different sized boots. The pictures below detail this variation on the DOJ's. A similar issue exists at the other end of the axles with the CVJ's. I need help identifying the axles so that I can purchase the right sized boots. Note that the infamous "Wheels and Axles" identification chart - posted above by Dee2 - unfortunately does not have the information I am looking for.
