7.3 turbo screech at 2800 rpms help
 

hello i need any info on anyone that knows what i need to do.... it happens when i having to hit the passing gear or just havin to floor it to get into traffic. no major mods just a k&N oem replacement everything else is stock. truck is pretty well takin care of for a truck with 213K.

its an awful sound. the only thing i can relate is an chalkboard/metal screech. an it only happens around 2700-3200rpm. i think ive might have thrown the bearing in the turbo.

truck is a little tired just seems like there should be a lot more power and im anly getting 12/13MPG.
