Default Jdm cv axles

Does anyone know off the top of their head if the axle length of the jdm gc8 / gf8 is the same as usdm gc8 /gf8 axles? Could i replace my gf8 wrx axles with usdm axles such as for an rs2.5?

I am starting to experience some cv knock when turning and since so many jdm usdm parts are lego mix and match it seems important to ask right away so i can start sourcing parts for this project asap. Finding parts here in canada can be a pita on occasion.

Thanks. Next and hopefully final quick question. Axle Splines. Outer splines are consistantly listed as 27. And the shaft lengths seem to be within 1/8th of an inch but the inner splines concern me. I have a '93 jdm rhd wrx that regretably has an atx. I see impreza axles for the usdm 93 model year with 23 inner splines or 25 inner splines. Any ideas?

pretty much all AWD front axles are the same (93-01 impreza, 90-99 legacy)

if you have a mechanical rear diff, with different L vs R axles in the rear, then 1 axle is a regular 93-97 impreza rear axle and the other axle is super rare JDM/EDM only

if you have a regular open/VLSD rear diff, then you need axles from any 93-97 (phase 1-ish) Impreza. for phase 2-ish (updated interior, "RS" style basically 98+) the diff splines changed but the hub splines stayed the same. (in related news, the 3rd gen legacy 00+ the splines changed on the hub side too)

if you are talking about front axles. then almost all EJ tranys both 5 speed and 6 speed had 25 inner splines, the only EJ trans with 23 was the FWD 5 speed in the early 90's.

great info, the axles have about 1" of compression and extension from the center or ride height so any axle that is close will almost always work as long as its not more then .250 to .500 off.

Here's a question...

I have a jdm v5 4.11 trans and it came paired with a jdm r160 rear diff and axles. I was told the rear diff was non lsd. This was put in my bugeye. Now i believe i am having rear diff issues and i have a spare 4.11 rear diff from an 97 auto brighton impreza. can i used the axles that came with my jdm rear end?

I'm curious too. I have a Version 4 STi drivetrain (with the DCCD; so does that make the rear diff R180?). Can I use my current hubs to connect the STi axles it came with?

Most of the jdm cars have abs while the na ones do not.

Does it matter? Are the abs rings easy to move over?

so just to clarify from those of you smarter than me; I've got a 2001 rs with a v2 sti trans and I need a new front passenger axle. Am I understanding this correctly that I can just go to autozone and purchase an axle for an 01 rs and it will work with the v2 sti trans?
