I was wondering if axles from an SI 5 speed would work on an STD 4 speed transmission. I need to replace an axle on my std and the autoparts store i work at lists two different parts for 5 speed and 4 speed. but will the 5 speed one work because I plan on upgrading to 5 speed soon. thanks

 

I think one is 23 spline and one is 26. std and hf have 23 i believe. all others are 26 for ef if I remember correctly.

 

i think the hub side are the different ones

 

so i guess they wouldnt work then? which means if i got a new tranny i would need to replace both my axles?

the inner side of all d series axles are the same the input shaft is different on jdm zc tranny thats it, you can use your 4 speed axles you can use automatic axles it doesnt matter as long as it fits your hub it will fit your tranny, and if you get a jdm zc tranny make sure you have the right clutch before you put it in

 

i have a 90 dx. std. came 4spd...no clock..no ac...no side mirror. swapped a b series into it. i also have a 91 si with a d15b.. axle went bad on the si so i used the spare axles from the dx. had no problems

 

thanks guys
