I had submitted a reply earlier but I see that it was lost. I am not so rude as to ignore either the information given me on this site or Ronnie's very kind request for an update.
My axle did not have a grove, or any place I could hammer on to seat the snap ring so my only option was using my hands to push as hard as possible. I did put the axle in but never got that satisfying click or clunk that allowed me to feel confident it was properly seated. It sounds like it's turning the gears in the transfer case, but I figured when I installed the knuckle and hub I'd get a good idea of whether it was in as far as it is supposed to be. About that time I noticed I neglected to install the boot and stop on the new strut rod so I had to remove the strut assembly to correct that moment of stupidity. I then decided I did not feel the new strut, which had been in my garage for years, was working properly [the seals probably dried out] so I ordered a replacement that put the whole project on hold. I was then offshore for a few days and just returned. The strut should arrive today or tomorrow so I hope to have a more definitive answer on how this project went after that.
