Idler Pulley Assembly
The idler pulley maintains tension on the drive belt and spins at high RPMs. High-frequency squealing occurs when the pulley's internal sleeve bearing loses lubrication, causing the metal shaft to vibrate at high frequencies against the pulley hub. Replacing the assembly restores a low-friction rotation point for the belt system.

Drum Support Roller
These rollers stabilize the drum during rotation and are subject to constant radial loads from the weight of wet laundry. Squealing originates from the internal bronze bushings when they become contaminated with lint or depleted of factory lubricant. This failure results in increased rotational resistance and harmonic resonance that manifests as a squeal.

Dryer Drive Belt
Over time, the belt's poly-V ribs can become glazed or hardened due to heat and friction. If the idler pulley or drum rollers offer resistance, the belt slips against the motor drive pulley, creating a high-pitched friction squeal similar to a car's fan belt. It is often replaced alongside pulleys to ensure system integrity.
