Drum Support Roller
The drum support rollers utilize a sintered bronze bushing that relies on a thin film of oil. When this lubrication fails due to heat and lint infiltration, the resulting metal-on-metal friction at high RPMs produces a distinct high-pitched squeal. Replacing the roller restores a smooth, low-friction interface for the drum's rotation.

Idler Pulley Assembly
The idler pulley maintains tension on the drive belt; if its internal bearing seizes or develops excessive play, the belt will vibrate or slide against the pulley surface rather than spinning it. This friction generates a high-pitched harmonic resonance that coincides with the motor's operation.

Drive Belt
If the drum rollers or idler pulley have partially seized, the belt will experience localized glazing (smoothing) or 'burning' from the motor pulley's friction. This glazed surface lacks the necessary coefficient of friction, leading to a squeal as the belt slips under the torque required to rotate a full load.
