Hi i was wondering if anyone knew if the axel from a subaru impreza sti would fit in a honda accord 4dr spindle?

 

I doubt it.

One way to check is to look up the part number from an autoparts store for both vehicles from the same supplier. If they have the same part number, they are identical. If not, then there is likely a difference.

 

I know they wont have the same part number diff manufacturs. I want to find out if they have the same spline count. I am trying to figure out what I need to do to put a boxxer 4wd motor and drive train my accord
