If the motor is tied directly to the spindle..remove the motor and
run. If you still hear the squealing..check the sheetmetal around the
fan and see if it got dented. If it still squeals...hold a long screw
driver to the bearing areas on each end and put the screw driver
handle in your ear for a stethescope.

Um... why not just use the _almost_new_ Snap-On Mechanic's Stethoscope he
bought for $2.00?

Seriously... It must've been over 40 years ago that I learned the value
of having an _actual_ professional stethoscope with interchangable probe
tips in the kit.

Especially for machines with big tin bodies around them, they're
invaluable for finding where the real noise is coming from.

Further, unless you stick it into a running fan, or light it on fire, a
good stethoscope is a one-time purchase.

There are inexpensive electronic versions with contact microphones, too.
I dunno if they'd last forever like mechanical ones do, but if you keep
the batteries stored separate from the tool, one should last many
decades.

Good point.

I bought a stethescope a few years ago for just this need..and found
out it works very well...but a screw driver works Almost as well and
doesnt need any special care in my tool box.
