Steering Clocking suddenly off ...
The first thing I would check is the Grant steering wheel hub. If it wasn't super tight, it could have spun on the steering shaft.
Good point for the aftermarket wheel.
Which I have absolutely know knowledge of.
Now on my daily driver I eliminated the "master key" in the factory wheel hole.
I can clock it any way I want to.
I can move it one tooth over if necessary for perfection.
The other thing is those tie rod ends.
I just found one that the clamps had been over tightened sometimes in it's long life.
The threads were holding but it actually has a little wiggle in them.
The clamps were past being able to hold tight.
He REALLY needs to look at those good and soon.
Especially not knowing what a person doing the alignment might have let slide..
All things being not worn out, I would say the tie rod ends are the weak link.
