Im trying to change my passenger side axle on my b16a1 CRX.
Im having some difficulty.
When I slide the new axle into place it only goes in 3/4 of the way in and stops. It will NOT go any further. The old busted axle goes in all the way with no problem at all. Both the new and the old axles are identical axles from Autozone.

The teeth on both axles are identical and not damaged at all.

Is there something that Im doing wrong?

Any insight would be much apprietiated.

Thanks
Mike.
