I'm certainly no an expert on this -- at all. However, I recently had what
sounds like your situation. Shimmed up the front of the stack. The stack was
causing the keyframe to twist, pulling the treble side up. It helped that I
had read about this on Pianotech and happened to remember it. Thanks to Ed
Foote, as I recall.
