Well first let me just say thank you for SEARCHING before posting.sorry to revive an old thread but the hub and axle can be removed from the housing together from what i gather where to i hit it. on the hub?
If you intend to wheel it just get a one piece axle kit and be done. Stronger axle shaft, better design and easyer to install.
Now if you want it to be original CJ that's fine too. But don't take it off road and expect the two piece axle to live long.
You might want to explain why you are taking it apart? And what you intend to do with the old CJ. Makes helping you a bit more simple.
