Drum Support Roller
The drum rotates on four rollers; when the internal lubricant dries out or the bearing seizes, the friction causes the outer rubber to wear unevenly, creating a flat spot. This flat spot creates a rhythmic thumping sound as it impacts the drum's rolling surface with every rotation. Replacing the rollers restores a smooth, circular path for the drum to travel on.

Dryer Idler Pulley Assembly
The idler pulley maintains tension on the drive belt; if the pulley's internal bearing fails, it can wobble or spin eccentrically. This eccentricity causes the belt to vibrate and 'slap' or thump against the cabinet or drum. This assembly includes the wheel and tension arm to ensure consistent belt tracking.

Drum Drive Belt
Over time, the multi-ribbed belt can develop cracks or 'chunks' where the rubber has delaminated. As the damaged section of the belt passes over the high-speed motor pulley or the idler pulley, it creates a momentary loss of tension and a physical impact sound that translates to a thumping noise inside the dryer cabinet.
