Dryer Idler Pulley Assembly
The idler pulley provides tension to the drive belt and spins at a high RPM. When the internal ball bearings lose lubrication or the race becomes damaged, the metal-on-metal friction creates a high-pitched harmonic squeal. Replacing the entire pulley assembly restores the smooth, low-friction tensioning required for the belt drive system.

Drum Support Roller
The drum rotates on four support rollers. If the internal bushing of a roller wears out or becomes clogged with lint and heat-degraded grease, the roller can seize or drag against its shaft. This resistance produces a consistent squealing or chirping sound as the drum forces the roller to turn against significant friction.

Dryer Drive Belt
If the idler pulley or a roller has seized, the rubber drive belt will slip across the moving motor pulley. This slipping action generates heat and a high-pitched 'belt squeal' similar to an automotive fan belt. A glazed or stretched belt loses its coefficient of friction and must be replaced to ensure efficient torque transfer.
