The squealing a scraping is most likely the idle pulley. i would replace that and the belt then see what happens
Youre cat :) It's more than likely the fan belt needs to be tightened
Tighten the belts
It's probably under inflated.
it must be something loose under the body

If changing the belt and tension pulley did not resolve the high-pitched squealing sound, it could be a sign of a failing alternator, idler pulley, or a loose accessory pulley. I recommend having a mechanic inspect these components to identify and fix the issue.
Most common culprit is a slipping belt.
A squealing sound when letting off the gas pedal can be caused by several issues, including worn or loose serpentine belts that may slip under load. It could also indicate problems with the brakes, such as worn brake pads that are making contact with the rotor. Additionally, issues with the engine's accessories, like a failing alternator or power steering pump, could contribute to the noise. Identifying the source typically requires a thorough inspection of the vehicle's components.
usually loose belts.
I suspect a bad harmonic balancer. Sloppy and making noise at idle belts squealing while under load. If vehicle has an serpentine belt system could be the idler pulley.
Look to the alt. belt. It may squeal under load.
