I have a squeak sound coming from my Harmonic balancer. I pulled the belt off to see where the sound was coming from. There is no wobble or play in it. A little about my car. It’s a 2002 4.75 MMR 750 with a 4r70w and a Journal bearing PT7675 ON3 turbo kit. I have good oil pressure 100psi at start and 45 when warmed up. The balancer is a Steeda Underdrive pulley. When I listen with a stethoscope on the turbo what would I hear if the sound is coming from the turbo being that the turbo is the only other thing spinning with the belt off. I have no knocking sounds in the motor either. YouTube link with the video...

Thanks

If I put stethoscope on timing cover near the crank I hear it in there. If it was a bad crank trigger would it be throwing a code?
