Alan,
If I understand your inspection correctly all flight controls
and control wheels are confirmed at neutral, the nose wheel had to be
re-adjusted back to center after the incident. I would concentrate on
taking the steering rod end out and inspect the threads on the rod end and
the push tube. They could be stripped out just enough to self adjust again.
I'd also check the rod end itself for straightness and hardware at the aft
end of the steering push rod attachment to the control column for condition
too. Lastly inspect the bottom of the control column where the steering rod
attaches for damage.
Trouble shooting by e-mail can sometimes be a hit or miss
proposition. In my experience I've seen stripped threads on the rod end or
steering push tube that would cause what you are describing. Please keep us
in the loop on what you find.

Here is something I have not figured out.
Before replying you may want to take a look at the front end of your coupe
or an assembly drawing.
A coupe with single fork nose wheel hits a bump while taxiing and all of a
sudden the nose wheel is pointing about 25 degrees to the right.
The coupe can be steered into right turns but not to the left.
When looking at the problem, the nose wheel is well attached to the strut
tube. The steel nutcracker is OK, all bolts holding the two halves of the
steering collar are tight and OK. the steering ball has the through bolt and
it is OK. The steering rod is OK. removed the floorboards and the swivel on
the bottom of the steering yoke is OK. All cables and chains are OK. The
ailerons and rudders and rams horns all line up but the wheel is still
pointing right.
I removed the steering ball and adjusted the threads on the steering rod
down as short as it will get and now the wheel is lined up with everything
else. it flies as well as ever, and steers much better than before the bump.
But that is not the way it was before...
So what happened?
What changed the geometry between the nose wheel and the ball on the bottom
of the steering column?.
The engine mount holds the strut in place and it has not changed shape...
The steering column has not moved forwards or changed place...
