Did that "blue" shaft got cleaned and lubed while you were doing the
Lower Steering Shaft rework? Steering box is tied to the frame.
Steering column (and wheel) is tied to the body. That splined shaft is
the only real interface that moves between the two and if it gets stuck
and it can do what you're describing. Maybe worse if slightly off-center.

This happened to me. Might not be the same thing you're experiencing
but just throwing it out there.
