You might try rebushing the guide.. also... all squeeks and buzzes in pianos
can seem like they are comming from one place, when they are actually coming
from another. Sometimes you could swear on your grandmothers wedding shoes that
you are right, and find out in the end the problem was comeing from elsewhere.
So... if all fails, start looking around for other sources. Check inside the
pedal box, and the bushing at the back end of the pedal.

One thing I find very often that may resemble a "click" sound is the jacks
slaping back on the rest / stop spoon (or whatever the particular configuation
on this grand is). Sometimes the repetition spring is too strong, sometimes the
jack centers are too loose, often enough it is the felt part of the jack
position regulation button that has gotten packed down hard. Combinations of
these can cause either a "thumping" or a "clicking" noise depending on how
things play out. There are lots of other things that can cause your problem,
and you will no doubt get plenty of ideas from several on this list, so without
further aduie.... I defer to them...grin

Always fun to hear what, in the end, the problem turns out to be.. so keep us
all informed, are you kind.
