If the splines are boogered up the wheel could be hanging up and not sliding all the way on
Funny you should say that. I noticed the shaft too but dismissed it.

IIRC there is a keyway spline on the column and on the wheel if the two were not lined up wouldn't that too prevent the wheel from sitting all the way down, mark up the splines?
