Just replaced the hub on my driver side of my rex and got a new rotar and axle.. well here i go to put everything together and so far everything is good. i make sure the axle is in all the way, which it is, and i get the calliper on for the breaks and i put it on the ground ready to go, put it in gear and the wheels wont spin... it sounds as if the axle popped out and when i jack it up it, it snug in there, but the weird thing is the passenger side wont turn ether. and i know my tranny isn't fucked up...its all stock, the steering wheel will turn the wheels just the wheels don't spin when i put it in gear.. clutch is fine, maybe the axle gears got knocked out of alignment?

 

Hows your motor mounts because a bad mount will pop axels out

 

If I could remember right crx are front passenger drive wheel.
You might want to look into the passenger side axle.

 

Are you sure they sold you the correct axle? I've been in a similar situation but with a clutch.
