Warren,

       The damper lift rod hangers are not aligned properly.  Remove the
action from the piano and remove the left most hanger retainer.  Check it
for wear and if it is severly worn replace the felt and replace it and test
the lift.  This could cure the problem.

        If not remove the retainer and remove the rail.  Be careful not to
scress the damper pinning or move the dampers overly much.  Check that the
rod is straight, the hanger arms are parallel and that the hooks are all in
the same plain.  Bend the arms and hooks  accordingly.

        Check the hanger retainers for bushing wear.

        Replace the rod, carefully and gently and replace the action in the
piano.  Check the timing.

        The alternative is to retime the dampers as they are and lubricate
the hangers to remove the squeak.

        Also, damper springs can squeak in their seats and damper lift felt
can squeak agains a dirty or corroded rod.
