Drum Support Roller
The support rollers are the primary load-bearing interface for the rotating drum. Over time, the outer rubber layer can develop flat spots or the internal bushings can seize, causing the drum to drop slightly and 'thump' with every rotation. Replacing these rollers restores the concentricity of the drum's rotation path.

Drum Drive Belt
A drive belt that has begun to delaminate or has a section of its ribbing missing will create a 'slapping' or thumping sound as the damaged section passes over the motor pulley. This mechanical discontinuity creates a rhythmic vibration that is often mistaken for a drum roller failure.

Idler Pulley Assembly
The idler pulley provides constant tension to the belt; if its internal bearing fails or the plastic wheel develops a flat spot from friction heat, it will oscillate violently. This oscillation manifests as a heavy thumping or rattling sound under the load of the drum.
