RacingFlyer Posted July 18, 2008 Share Posted July 18, 2008 Hello, I'm, a Newbie and I just discovered your website. I have a 1989 GL Turbo (EA82T) wagon, AWD with an automatic transmission. I have been going crazy trying to figure out what front CV axle I need on this car. I have one going bad, and I need to make sure I order the right one and have it on hand before pulling the old one (daily driver...). What's driving me nuts is that depending on the websites and catalogs I'm looking at, some say I need a 23-spline Inboard CV axle, others say 25-spline IB... I believe my tranny is a 4-speed (it has 1-hold button and positions 2-3-D-N-P). Would somebody have the knowledge to clarify this issue for me?

idosubaru Posted July 18, 2008 Share Posted July 18, 2008 Might want to search on here - for some reason my memory is tricking me so i don't want to say what i think, but i do know the information is already here. One way to make sure is that your turbo transmission splines are identical to the XT6 and they are all the same (FWD, AWD, auto, manual, doesn't matter). So if you look up an XT6 (6 cylinder 2.7 liter) front axle and figure out the spline count - yours is the same. that being said - i'd recommend MWE or Subaru axles only - aftermarkets are plagued with issues. just do a search here for "axle" and see all the problems.

Thanks for the input and advice. I did make some more research. I have found this thread: http://www.ultimatesubaru.org/forum/showthread.php?t=88210 So it seems that 25-spline = 4EAT tranny and 23-spline = 3AT tranny. But in my case, an '89 EA82T with AWD should have a 4EAT so I need a 25-spline. If somebody thinks I'm wrong, please let me know. Otherwise I am on to buy a new axle. Thanks grossgary for the recommendations. Link to comment Share on other sites More sharing options...
idosubaru Posted July 18, 2008 Share Posted July 18, 2008 The major difference is the turbo verses non-turbo. a car without a turbo (but everything else the same) as yours will have the opposite spline count. pretty sure all turbo's are the same....and i think it's 25 spline, i'd just hate for my memory to be playing tricks. i'm surprised no one piped up yet. Subaru RX's (1988 for instance) are all turbo - so any axle from one of those would work as well. I highly recommend MWE (they've posted here before). He'll know exactly what axle to send you...and you'll avoid all the after market nonsense. Link to comment Share on other sites More sharing options...
Spiffy Posted July 18, 2008 Share Posted July 18, 2008 this is referenced from the USRM: http://www.ultimatesubaru.org/forum/showpost.php?p=642822&postcount=9 --Spiffy Link to comment Share on other sites More sharing options...

I am confused The post from Miles Fox seems to imply that 4EAT has 25 splines. So, now I am lost again... Help anyone? I knew I had a weird animal on hand. There is just not so many GL Turbo Wagons with an A/T and AWD out there it seems... Link to comment Share on other sites More sharing options...
GeneralDisorder Posted July 18, 2008 Share Posted July 18, 2008 5 speed manual = 25 spline. 4 speed auto = 25 spline. 3 speed auto = 23 spline. 3 speed's were not used in turbo's after 87. GD Link to comment Share on other sites More sharing options...

presslab Posted July 19, 2008 Share Posted July 19, 2008 Just another confirmation, my 88 GL-10 turbo 4EAT has 25 splines. I bought cheap Kragen axles and had to return a couple but the latest set is going strong and it only takes a half hour to switch it out. Link to comment Share on other sites More sharing options...
Gloyale Posted July 19, 2008 Share Posted July 19, 2008 http://www.ultimatesubaru.org/forum/showpost.php?p=642822&postcount=9 That is a page I scanned form the 89 FSM. IIRC at the time I posted it for a Refference to axle lengths and types. Here is the kicker, The chart on the bottom of the page is still the same chart from the 86 FSM. The Autos reffered to in that chart are 3spds, although they didn't put those in AWD Turbos after late 87. There are instances all over in the FSM where old info carries over, even though it's not correct and other parts of the FSM have the corrections. To the OP, You do need 25 spline axles. Order them for a Turbo, Manual trans car, and you'll get the correct ones. *NOTE* 2wd Turbo Automatics did continue through 89 and did still use the 3spd auto. 23 spline Link to comment Share on other sites More sharing options...

GD 2wd Turbos still used the 3spd until 89. 23 spline. *note* The 2wd, automatic, Turbo axles have a beefier set of joints than standard 23 spline axles. A real score for offroading in D/R trans vehichles, if you can get them. Otherwise all the above is correct. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted July 19, 2008 Share Posted July 19, 2008 Otherwise all the above is correct. Ah - yes I was only talking about the 4WD's. Never owned or worked on a 2WD turbo. GD Link to comment Share on other sites More sharing options...

GeneralDisorder Posted July 19, 2008 Share Posted July 19, 2008 I just wonder why they made em:rolleyes: ????? But they did. I can't see the appeal of them, but then I don't see much use for anything that's FWD only. RWD or 4WD/AWD are the only way to go for me. FWD answers a question no one ever asked IMO.

idosubaru Posted July 20, 2008 Share Posted July 20, 2008 I just wonder why they made em:rolleyes: ????? But they did.maybe they were cheaper, marketing thing? this isn't why they made them, but 40+ mpg is appealing to a few. Link to comment Share on other sites More sharing options...
