6.4l Serpentine belt chirp noise fix

[WANTED]

It's the only thing that makes any sense. Thanks for helping me check.

Talked with my buddy, He said it sounds like something in the pump gears may have broken off but is intact to work. He said don't push it.

So I finally had my transmission rebuilt, and the pump was not the issue in my case. What was the issue was my up-pipes, which were leaking and creating a chirping/squealing sound. Not even close to the sound of an exhaust leak I'm used to, but sure as hell the leaks were visible when the transmission was off.

Replaced both tensioner pulleys and belt. Chirping problem fixed on my 250 SD 6.4 diesel.
