Steinway clicks, clacks & groans

[Newton Hunt]

I would take an appropriate tool and but a small bend in the spring
about the center to force the spring against onside of the post, or
the other.  It will take VERY little bending and should take about
fifteen minutes for the entire set even after trying samples at
section ends.  You want the spring just to touch the post, securely
enough to remove noise but not so hard as to impede spring
functioning.
