Dryer Idler Pulley Assembly
The idler pulley maintains tension on the drive belt. When the internal ball bearings or sleeve bushings lose lubrication or develop flat spots, the high-speed rotation under tension produces a high-frequency vibration that manifests as a piercing squeal. This component is the most frequent point of failure for this specific acoustic symptom in LG dryers.

Drum Support Roller
LG dryers utilize four rollers to support the drum's weight. If the internal bore of the roller wears out or becomes contaminated with lint, the friction between the roller and the stationary shaft creates a metal-on-metal squeal during rotation. Replacing the rollers restores smooth rotational movement and eliminates the noise.

Dryer Drive Belt
While less likely to be the primary cause of a 'squeal' compared to the pulley, a glazed or stretched belt can slip against the motor pulley under load. This slipping creates friction-induced noise. It is often replaced alongside the idler pulley as the two components interact directly and usually wear at similar rates.
