I would bet that when the shaft was disconnected, it was pushed a few mm back. That "broke" the stuffing box "joint" that had created during the localized overheating event. That thing can be pretty tight, and moving it axially just a little could have loosened it.
Regarding the "wobble", I would just turn the shaft manually with the engine stopped and see if it still shows a bend (maybe with a machining comparator?). Engine mounts and cutlass would "wobble" the shaft when spinning with engine running, not with engine shut down.
