The Whirlpool WPW10177428 Dryer Drum Support Roller and Axle enables smooth, stable drum rotation during drying cycles. The roller turns on its axle inside the dryer cabinet, holding the drum in proper alignment. A worn roller or axle may cause rumbling, squealing, thumping, or uneven drum movement. Replacing damaged components can reduce unusual noise and restore proper rotation. https://www.partsmelange.ca/whirlpool-wpw10177428-support-roller-for-dryer
