Axle help

will a 89 4dr dx (5 speed) axle fit on my 91 civic hatch std (4 speed)? i need a new axle cause mines bent :-\ and the junk yard is way cheaper than advanced or pep boys.

I think the SPLINE count is different for the STD model (I have one too). I'm just not sure if it's the Si model that is different by itelf (meaning STD and DX are the same) or if it is the STD that is different by itself (meaning DX and Si are the same). I believe the CRX HF uses the same axles as the STD Civic does. Can anyone else confirm?

DX and SI are the same...
the difference is the STD hub

so thats a no on the 4dr axle right?

yup 5speed axles wont work in 4speed hubs

are the steering knuckles all the same?

Not Sure, Check Part #'s
