[Shotimes] Bearing whine? dunno

[Robert Bruce]

I just had this problem on my 95 T-bird 4.6L.  Found that both idlers for
the serpentine belt were worn out.  Fortunately McMaster-Carr
(http://www.mcmaster.com/) had the right bearings in stock.  Total cost was
under $20.  Took all of about 15 minutes make the repair.

As others have said, it could well be the idler pulleys for the accessory
belts.  It
could also be the tensioner for the timing belt.  They do a LOT of work, and
are
getting old.

You can use a long screwdriver and your ear to check the idler pulleys, and
the
accessories themselves.  With the engine idling, carefully put the tip of
the
screwdriver against a solid portion of the part you want to check, and put
your ear
to the handle.  Press down with your head to transfer the sound from the
screwdriver
to your ear.  Foolproof, especially when you find the right noisy component.

There is a tool to do this job...a mechanic's stethoscope.  It should be
available
at most auto parts stores.
