John,

I appreciate your response, but it ain't like this is my first C4. On the
contrary it's my 4th and I have more than 300,000 miles in C4s, another
40,000+ miles in C5s.  I know these cars. Thus, my post asking for
specifics.  And, while I weigh more than 200 lbs that has NEVER been a
problem in past cars, nor this one. I have half dozen C4 buddies that have
equal experience with C4s and all weigh more than 200 lbs.  So, let me
restate my problem, with a couple of additions, just to clarify:

I took my C4 in for a 4-wheel alignment to a place where I have been having
4-wheel alignments done for the past 3 C4s. When I went in my car was NOT
pulling to the right.  When I left, it was.  I went back. We talked. We
disagreed.

I put new tires on it. Then, went back, telling them, "Nope."  So. I took it
to another place - another  place that I trust.  They told me it is out, but
that they could not fix it, due to a limitation on their machines.

So, I took it to a third place. A Chevy dealership where I have been having
cars worked on, off and on, for more than 20 years. The owner is a personal
friend. I know EVERYONE in the dealership.  The dealership Service Manager
and the Head Service Writers (they race Vettes and Camaros) spent two hours
on the car, and when done, the car still pulls to the right. AND, the
steering wheel is still not centered. (That last sentence is 1/2 new
information."

Bushings are good.  Now, I ask again:  Anybody got some clues to offer up
before I drive the car 80 miles to a Technician that I've known for 25 years
and has worked on three of my previous Corvettes?

Maybe it's C6 time. :)
