I have had similar noise problems, and have been told that there is a small
piece of metal that contacts the bottom of the spindle on the controller side
to help further discharge static. This metal can contact, and thus generate
some painful noise, if the lubricant wears off. The solution suggested was
to pry back the metal and all would be fine. I have received reports that
this has worked in other cases. 

I don't know what you could do to replace the lubricant, but since the metal's
use is for added protection, perhaps its removal is not of serious importance.

Regards,
