Safety First: Unplug the dryer before removing panels. Sharp edges may be present.

Access drum supports: Remove the front panel and, if necessary, the drum to expose the drum support rollers, idler pulley, and glides.
Inspect rollers: Spin each drum roller by hand. They should turn smoothly and quietly. Replace any that wobble, bind, or have flat spots.
Check idler pulley: Rotate the idler pulley. If it squeals, feels rough, or is seized, replace it.
Inspect glides: On models with front drum glides, check for worn-through Teflon pads or exposed backing. Replace as a set if worn.
Replace as a kit: Whirlpool often offers drum support kits including rollers, idler, and belt. Replacing all wear components together is recommended.
Reassemble and test: Reinstall the drum and panels, ensure the belt is routed correctly, and run the dryer to confirm the noise is gone.
