Hey, im sorry hanyo, it's not the bearing, the reason why the sound went away when you sprayed the bearing area is because some of the lubricant contacted the belt and lubricated the belt at the same time, which is a coincidence. That sound is coming from the drive belt, reason being is just within time, the belt will stretch a bit thus loosing tension. Best way and cheapest way to get rid of the noise, which you've already done but will come back is to just get a rag and a pair of long needle nose pliers, rap the rag around the pliers and spray it with a cleaner solvent such as brake clean and run it along the inside of the belt to clean up all the dirt. Then for the sure fire way to kill the noise is to put a little grease on the inside belt (obviously with the engine off). and the noise should be gone!, hopefully the belt is still good at this point.
