Does anyone know where you can get replacment pulleys for the alternator.

I have an anoying noise that i thought was the Aux belt, so i changed the belt but the noise was still there.

I've now changed the auto tensioner and idle pulleys but still the squeaking remains.
I think the noise is coming from the alternator pulley so i want to change that to see if the noise will stop.

The only time i can get the noise to stop is if i spray silicone on the belt, this lasts for about 10 mins and then the noise comes back.

i was hoping to get away with just changing the pulley.
Bloody alternators are exspensive and a pain to change on these cars.

thanks mate.

I've checked Ebay, all second hand ones, i know if i get a second hand one it will break or squeal.
thanks
