  This was basically it.  The problem was that the bolt that you attach the action to (at the top) was too high in the treble.  Every time you raised the damper lift rod with the pedal, the action would torque with the upward pressure, and when you released the pedal, it would make that creaky sound.   I noticed that when the action was bolted in place, I could take hold of the far right action bracket and move it in and out.  I originally thought there were loose screws on the action rails but this proved to not be the case.  It was actually the entire action that moved upward when the pedal was depressed.

The solution was to lower the bolt, (I used a hammer to bend it downward slightly) so that it held the action in place more firmly and the creak went away.   
   
  I'm surprised at how many of you were either very close or on the money.  As I solved this one, I came across so many things that seemed like they were probably the cause, and eliminating each one finally led me to examine the fit of the action in the piano.  But I never heard of this one before.  
   
  Hey, I'm just happy I figured it out and was able to satisfy the customer.   The bill for eliminating this squeak?  (90 minutes @ $...?)  
   
  This was a piano that I sold to this client.  The sale included a free tuning in the home and a guarantee.  I don't mind.  Nine times out of ten a drop of Protek and I go home.  So this time it took a little longer.  She offered to pay me but I refused.  Having the problem solved, I can look back on it and say I enjoyed the challenge.  And I was able to find a few other little problems along the way and solve them before they created any more trouble down the line.
   
  Thanks for your responses.
