Some great past culprits revealed here. Thanks everyone. I will add that a guide rail stud that is somewhat loose in the threads can make a squeak. I remove the stud and wrap teflon plumbing tape around the threads to tighten it up.
Teflon plumbing tape is useful for many things on pianos. Such as squeaky/loose/rusty/tight pedal trap pins and to wrap around the pedal pin so it is between the cloth and the pin in the Steinway pedal pivot system and then you can really tighten down the screw and have a stable, tight, freely moving Steinway pedal. I have ones done this way that have not loosened in ten or more years of daily use.

Hi Clarence, the most illusive one I had was the underside of the screw head was rubbing on the leaf spring. Many times that action came in and out of the piano. I was sore after that not to mention the customer added the comment "oh by the way, the soft pedal squeaks. Could you look into that for me?" as I was about to leave after tuning the piano.

I have a college with a newer Steinway D that the una-corda is squeaking. They have a concert on it in a couple of weeks. Any suggestions on the Squeak?
