Shaper feed screw jamming ????? Help needed.

Hello to all.
Please combine your many years of experience and find me an answer.
Last weekend the shaper crossfeed screw became difficult to operate. I lubed it all, cleaned the screw and oiled it, backed off the gibbs, cleaned them and reinstalled. It got that hard to turn the hand wheel I decided to strip it down and remove the swarf that was obviously in the shaft nut. The hand wheel and ratchet gear are roll pinned to the shaft and the only endplay adjustment is the two nuts on the other end. I took the hand wheel off and the drive cover with the feed lever as well. To my surprise I could turn the shaft with the ratchet easily. It is now easy to thread thru the nut. I can't easily remove the screw as it is burred a bit where it has worked in the nut but it came out 250mm and was in fine condition. There is no galling or pick up in any part and it was all dripping in oil.
This all happened once before and the result was put it back together and it was perfect. Today will see it go back together after a good deburr but I'm scratching my head. How can it jam up and show no sign of distress. Even the part of the screw most used showed no signs of pick up or damage.
Your thoughts?
