Default Need some help

I joined this website because im in need of some help with my truck.

02 Ranger XLT 3.0L Flex Fuel
Ill explain my problem, at random times, I hear a chirping, that goes away for a few days, and comes back for a few days. It happens when Idling, and when driving, whenever it wants to. Its a steady squeak that picks up a little bit depending on the rpm , when i shut it off too it does a long squeak. Ive went rounds fixing things trying to figure this out.

First of all I replaced the belt (obvious choice there)
Put a stethascope (spelling) on all the pulleys while running, while its chirping keyword, and nothing.
Replaced the tensioner
Ordered a PCV valve and tubing crankcase vents and replaced them (the rubber tubing was cracked, so i thought it might be the problem, ended up not being it).
Replaced another belt thinking i might of gotten a bad one.
Ive listened everywhere for this chirping, and cant pinpoint it.
I think, mind you I know sound is deceiving while a trucks running, but i think its coming from the back of the motor, but honestly its hard to tell.

Ive inspected vacumn lines, I havent notice anything wrong, transmission and Motor both run fine. (60k Miles and kept in great shape)

What would randomly chirp that comes and goes if its any of the usuals, (waterpump, alt, tensioner, idler, belt, etc)

Any Ideas, im stumped and this chirps driving me nuts.

X2. Spend the extra cash on a Ford unit, about 135-150 depending on stealership. Don't wait because when they do fail they usually take the engine with them. Do a search for info on what problems failures cause and replacement how to.

x3 Agreed. Sounds like you have tried everything to do with the belt. Is the chirping comming from the back side of the engine, or the front?
