George,
With the balls and shafts in place, and retained by the spindles, (which I sometimes call 'shaft retainers') I have about 1/4" of play. This is the same amount I have on the OD Willys.
I asked this question once, here or at the 2A while I was fixing the OD Willys. I can't remember which site, but the responses gave me an assurance that this much play is acceptable.
This is just an FYI. I am clearly no expert regarding these axles.
