Understanding the Problem
A noisy dryer drum is one of the most common dryer complaints. The sounds can range from squeaks and squeals to thumps, grinding, or a scraping/rubbing noise. These noises usually indicate mechanical wear where the drum rotates — commonly worn drum rollers, a failing idler pulley, worn drum glides/slides, a stretched or frayed belt, or a damaged drum bearing. Foreign objects trapped between the drum and bulkhead can also cause intermittent noises. Diagnosing the exact cause requires listening to where the noise is coming from (front, rear, or underneath) and checking for visible wear. In many cases the fix is a relatively inexpensive parts replacement and basic mechanical work: replacing rollers, the idler pulley, glide pads, or the belt. For grinding or heavy metal-on-metal noises, check the rear drum bearing/support and the motor shaft area — those issues can be a bit more labor intensive but still repairable at home with the right parts and tools.
Common Symptoms
Squeaking, squealing, thumping, scraping, grinding, or intermittent rattling noises during drum rotation; may be louder when the drum is loaded or when the machine is cold.
Common Causes
- Worn or seized drum rollers/supports
- Worn drum glides/slides or front drum felt seal
- Faulty idler pulley or loose/misaligned belt
- Worn rear drum bearing or support
- Foreign object (coin, button) trapped between drum and cabinet
- Loose drum baffles, screws, or mounting hardware

Helpful Repair Tip
Run the dryer empty and listen: if the noise comes from the back/rear area it's likely rollers or bearing; if from the front or under the door lip it's probably glides or a foreign object. Stopping the drum by hand and feeling for rough spots helps confirm worn rollers/bearing.
Frequently Asked Questions
Can I replace these parts myself?
Yes — most drum-related repairs (rollers, idler, belt, glides, seals) are DIY-friendly if you have basic tools (screwdrivers, nut drivers, putty knife) and follow safety steps (unplug dryer, turn off gas if gas dryer). Take photos during disassembly to help reassembly. If the repair requires removing the drum or motor and you’re uncomfortable, consider a technician.
How much will fixing a noisy dryer drum cost?
Parts for common noise fixes are relatively inexpensive: belt, rollers, idler, or glide kits typically range $10–$60 depending on brand and kit. Labor (if you hire a pro) adds to cost — expect $150–$300 total for typical roller/idler replacements. More involved repairs (rear bearing, motor) will cost more in parts and labor.
