James --
about 15 years ago I had a squeek for about a year until I checked the
front very carefully and realised that the front hub castle nut was
just a little too loose. Added a shim or two, retightened it, and now
all is well. I later figured out that what was happening was the hub
was sitting on the spindle just a hair crooked and the disk was coming
into contact on the back dust plate from time to time.
Regards,
Alan
