Why is my harmonic balancer squeaking?
if the squealing only occured when the car started it would be more likely a water pump bearing. If it only occurs when you enage the AC then it is a compressor issue. A harmonic balancer reduces vibration by allowing some slipage between the belts and the engine. It also absorbs woble.
How do you know if your harmonic balancer is bad?
If the harmonic balancer gets too old or fails and can no longer properly absorb the harmonic vibrations, the engine will shake excessively. The shaking will become even more pronounced, and therefore dangerous to the engine at high speeds.
Why is my car making a chirping noise when I accelerate?
If you hear a chirping or squealing noise when you accelerate, it usually means a belt is loose and slipping or the drive pulley for an accessory has become misaligned. Recommendation: Get it checked.

Can a stethoscope detect a bad harmonic balancer?
A technician with a stethoscope can pick up the; vibrations of a bad harmonic balancer. In some cases, you can also see the belt vibration. As the rubber deteriorates even more; you’ll notice engine vibration at higher (RPM)s. One of the first symptoms of a potential problem is engine vibration.
