Default need help on 04 jdm sti transmission problem!

Hi Guys,

I drive a 06 wrx and swapped out the 5MT for a 04 JDM STi 6MT a year ago. Recently, there are traces of oil leakage and the garage managed to pin point the problem. It appears that the front diff that i am using has two "versions", i shall elaborate.

The front diff has a splinter and connects to the left drive shaft with a locking pin. However, the right side has a newer connect mechanism where the shaft has a itself has a splinter and was torqued into the front diff. I understand it is difficult to picture this without any pictures, but i am hoping someone has an experience or two with these transmissions.

Now, the garage told me that i need to buy the right splinter from the front diff and an old styled front right shaft. Does anyone know where can i get them?

Thanks

So the LHS has a stubshaft and a female axle? The RHS has no stubshaft and a male axle? So what side is your leak coming from? If the trans is confirgured to use female axles then using a male axle without changing to an axle seal meant for male axles.....will cause said leak.
You might only need one correct axle seal to fix the leak. While that is sort of getto it is a simpler and lower cost repair. If you want to match up both sides then decide if you would rather have male or female axles. Then source the missing parts.

It is coming from the side where it is being inserted into the front diff and torqued down. And there is no "pin" to it. I heard this is the newer design. Could i just get the stubshaft and axle and call it a day?

Let's speak in USDM terms first.

02-early 04 USDM WRX/STi axles were female and slid over a stub shaft coming out of the transmission, and were secured onto the stub shaft via a roll pin.

Late 04-07 USDM WRX/STi axles are male, and they slide into the front differential.

Both of these styles use a different seal.

04 JDM STi 6MT should have the earlier female axles. Not sure why both sides are different; it sounds like someone must've messed with it. What I would do is buy the stub shaft and seal from Subaru, along with an 02-03 WRX USDM axle, and install that on the other side. It's much easier to put in the stub shaft than it is to take one out.

Part numbers are as follows:

Stub shaft - 38415AA110
Circlip - 805329010
Oil Seal - 806730042 (right side, yes they have different part #s)
Spring pin for female axle - 905190007

Easiest way to get the correct axle is to just get an axle for 02-03 WRX. They only came in the female style in those years, where as starting in 2004 it depended on when the car was manufactured which determined if it had female or male axles.

See this thread for more info: http://forums.nasioc.com/forums/show...ght=stub+shaft

Good luck.

As stated I would put the stub in and make it so they are both the same. That's pretty weird that someone was in there and did this to the trans. I will have a right front axle in about a week for sale if you still need it.
