Steinway L "clunk" help needed

[Roger Jolly]

Hi Ron,
            The Teflon bushing needs Very little slack to become noisy,
switch one or two wippens around to help isolate problem. I have  found
some very strange noises coming from S & S jacks over the years, just flick
the heel of the jack rapidly a few times on the worst note , and listen,
then compare with a quiet note. Similar procedure for the wip flange, raise
the hammer 2 to 3 inches and let drop on to the wippen, listen for the
difference.
Hope this helps
Roger
