Sometimes if the pulley is worn out the belt will bottom out in the pulley causing the anoying noise. The only fix was to replace the pulley at fault.

also try this quick check..
turn the steering, if the noise goes away or lessens while you are turning the wheel (it works better if you jack the front axle) then you need to check the float on the powersteering pump.
My moneys on the dust cover rubbing on the idler,have you ever replaced the bearing?,if you put the dust cover on back to front it will squeal it's head off.Start the engine and give the cover a squirt of WD and see if it stops. Pat
I always place the belt so I can read the lettering when I stand at the front of the vehicle, what do you think, is the belt rotating in the correct direction?

Wow, what a response. Thanks guys, I had no idea there were so many possible causes and that it was such a widespread issue. I've tried WD40 and silicone spray numerous times and they only last for a while. I've replaced the idler bearing about 15000km ago and one of the other ones. I'll try all your suggestions and if I'm successful in killing off the canaries, I'll let you know which method worked.
Many, many thanks again.
