I think that most likely the problem is the shaft was not balanced properly to begin with.

you can balance either steel or aluminum, all they do is weld a weight to it. if it is an aluminum shaft and they dont have a Tig, or a Spool gun for aluminum they can just find a suitable spot on the ends to weld a steel weight to. I don't recommend that, but I have seen it done, and it worked fine.
Most likely it wasn't done properly, or it looked like a good weld when it was on the bench, but the weight flew off first time it got a jolt.
That does happen sometimes.
