Kept hearing a squeak squeak in the mornings when cold and at night when car was cranked up, used to go away as car heated up. Got to the point now though where it squeaks the whole time, sometimes when its not even cold. Decided to research, heard a lot about idler pulleys going bad causing this squeak, found out that my car had the short belt mod put on it, so that eliminates one of the idlers to squeak, then the other idler was replaced with the belt. Finally caught the car squeaking when i had a can of wd40 and investigated to find it coming from my power steering pump pulley, sprayed some wd40 on the inside of the bearing and the noise stopped instantly. Called part stores and dealer, checked eeuroparts.com and all say you cant buy the pulley? Have to buy the whole assembly for $550???
