Steinway, Model M Grand knocking rattle noise

Steinway designs the damper system so that the damper wire
rides the side of the bushing just enough to prevent it from
vibrating but loose enough to move freely up and down.  The
adjustment is to use a pair of wire benders and gently bend
the wire just above the damper flange so the wire does ride
the side of the bushing, right side in the bass and left
side in the treble.  If the damper moves sideways to seat
itself when tri-bi-mono chords are sued then you are riding
the wrong side of the bushing.  Simple of a pain in the back
side.
