Mine knock - new ones ordered !

I had a ghost knock, couldn't find no matter what I did. Then installed the Konis, cleaned the top hat bearings and repacked them. Now the knock is very noticeable - I used an engineers stethoscope to make sure the sound comes from them. A minuscule play can be felt with a finger tip, but not seen. Minor indeed, but sound is annoying.

There's a tech bulletin on this issue too.
