Not sure what to say, I brought the whole shaft to DSI, the guy said it was NFG, needed re spline, new top welded on, rebuild, and balance. He said i was looking at $600.
Bought a used shaft and rebuilt that myself for $120 with new ball socket and ujoints. Took about an hour. And it was fun, first time working in my own garage, even forgot it was -10 in there.
Jeep runs great now, we will see what the long term results in.
