couple of things to consider. if it is a 1 piece d/shaft and you didn't cut it it shorten it there should be no prolem with the shaft. if you put iyt in the vise to remove a ujoint and tightened it up on the tubing then you quished it and possibly bent it. if you didn't alter the shaft or remove any you joints then you can't put it back in wrong
the thing that more than likely happened is that a ijoint cap came off and a needle or 2 dropped and is trapped in the nnd of the cap causing you a problem.
If it is a 2 piece d/s then there are a few ways to screw up the mechanism if you took it apart, but will await your response on why you removed it and what for
