2000 Dodge Ram with the 5.9L engine. It is making a "chirping" or intermittent "squeaking" noise... not at an idle but whenever I give any gas. Thought it was the serpentine belt- replaced it and it went away for about a week and then came back. Since hen I have replaced the Idler pulley, the tensioner pulley and the Alternator. It sounds like it is coming form the front top passenger side of the engine.

Remove the drive belts, then spin each pulley by hand. You should find one that feels wobbly or rough. This is the component that is most likely causing your chirp. Usually it is either the water pump or an idler pulley. DO NOT run the engine with the belts removed- the engine will overheated and severely damaged!

SOURCE: Can a alternator PULLEY make a chirping noise?

It's possible that the alternator is making the chirp noise (bearing) but I would try this first. Start the engine and allow the engine to idle and open the hood and take a spray can of WD40 and shoot a short burst onto the bottom side of the belt and pulley. Dont spray allot as this will cause the belt to slip. The WD40 is to lube the pulley grooves and belt a slight bit. Hope this works!

take a long pole as from a push broom and use the pole as a stethascope. place the pole to the power steering pump at a safe aera and place your ear to the other end of this pole.you will hear the churning of the bearing as the engine is running. do this to every part that runs off the belt. you will notice a big difference when you listen to all bearings. if all sound good as a normal churning noise you have a glaze of dried oil on your pulleys making the belt to sqeak
