Drum Support Roller
The polyurethane outer layer of the roller often develops a flat spot if a heavy load is left stationary or if the roller's internal bearing seizes. As the drum rotates, this flat spot creates a rhythmic thumping sound each time it contacts the drum shell's track. Replacing the roller restores smooth, concentric rotation of the dryer drum.

Idler Pulley Assembly
The idler pulley maintains tension on the drive belt; if the pulley's bearing fails or the plastic wheel warps, it can cause the belt to vibrate or the pulley to bounce against its housing. This mechanical oscillation translates into a thumping or heavy vibrating sound during high-speed rotation cycles.

Drum Drive Belt
Dryer belts can experience delamination or fraying where a section of the rubber separates or bunches up. As this 'lump' passes over the motor pulley and idler pulley at high speed, it creates a repetitive thumping sound that synchronizes with the motor's RPM.
