You didn't mention checking the steering head bearings.  I know from
sad experience that they can get incredibly loose through inattention.
Of course, you probably *did* check them among the "few other things".

Dumb story:  The first time I drove into Pittsburgh it was the middle
of the night but they had a lot of construction and traffic on the loop
around the city anyway.  I remember thinking "These potholes are
horrible!  Funny, they don't *look* so bad.  It must be the arc lights
they're using for the road work."  After getting to a friend's house
and crashing (on a couch, not the road) for the night, I went out to
prep my bike for the next leg of my trip.  Uh.  Wow.  1 and 1/2 inches
of slop at the wheel from bearings that probably hadn't been on
speaking terms for 500 miles.  If the wheel hadn't fallen from side to
side when I turned the handlebars, I *still* wouldn't have noticed even
then.  Dumb, but true.  I think I got to my friend's place about 30
miles from a REAL catastrophe.  Now I check my steering head bearings
periodically.
