Understanding the Problem
What this is: The dryer drum felt (felts or glides) cushions the drum and keeps it centered while the drive belt turns the drum. Worn felts let the drum rub on the bulkhead or rear panel and cause squealing, rubbing noises, uneven wear and drum wobble. A worn or broken drive belt prevents the drum from spinning or causes slipping. When both components are worn you should replace both — felts wear faster when the belt/rollers are bad, and vice-versa. Step-by-step diagnostic and repair steps: 1. Tools and parts: Unplug dryer and shut off gas (gas dryers). Tools: screwdriver set (Phillips and flat), nut driver (1/4", 5/16"), socket set, putty knife, needle-nose pliers, work gloves, vacuum, replacement front/rear felt seals (drum felts) and a replacement drive belt. Have spare drum rollers and idler pulley handy if they look worn. 2. Safety first: Unplug the dryer and, for gas models, turn off the gas supply and cap the line if you disconnect anything. Work in a dry, well-lit area. 3. Access the drum: Remove the lint screen and use a putty knife to release the clips under the top panel (if applicable) or remove top screws. Remove the dryer front panel or control console per your model to access the drum. Keep track of screws and wire connectors. 4. Remove the drum: Disconnect any door switch wiring attached to the front panel. Remove the front panel and set aside. Slide out the drum carefully (some models you may need to lift the drum out of the rear bearing first). Note the belt routing around the drum ribs — take a photo if needed. 5. Inspect components: Examine front and rear felts for flattening, tearing, or grease/dirt buildup. Spin the idler pulley and rollers by hand — they should turn smoothly without wobble or play. Inspect the belt for fraying, glazing (shiny surface), cracks or missing ribs. 6. Remove old felts and clean: Peel or pry off the old felt seals from the drum and the bulkhead. Vacuum lint and debris from the housing and drum edges. If there's metal debris or deep scoring on the drum edge, address it (lightly sand burrs) before fitting new felts. 7. Install new rear felt: If your dryer has a rear felt, fit it onto the drum flange or the bulkhead per the parts’ orientation (the felt usually has a lip that seats into a groove). Some felts also slip over the brake or bearing housing. 8. Replace rollers/shaft bearing if worn: If rollers or rear bearing are rough, remove and replace them now. This is recommended whenever you replace felts since bad rollers wear new felts quickly. 9. Reinstall drum and front felt: Place the drum back into position over the rear bearing. Fit the front felt onto the drum lip and ensure it seats against the bulkhead opening or mount bracket. Some models require a felt that attaches to the bulkhead instead — follow the felt shape to match the housing. 10. Install new belt: Route the belt around the drum ribs (make sure ribs face into the drum), loop it under the idler pulley and around the motor pulley to create proper tension. For most dryers: belt goes around the drum, under the idler, then around the motor pulley — the idler should press the belt tight when tensioned. 11. Check alignment and tension: Rotate the drum by hand a few turns. The belt should track in the drum ribs and the drum should turn smoothly with no rubbing noises. Adjust the belt position on the drum if it wants to climb the drum face. 12. Reassemble: Reattach the front panel, reconnect door switch wiring, secure the top and any other panels. Replace the lint screen and plug in the dryer (turn gas back on if applicable). 13. Test run: Run the dryer empty on a tumble cycle and listen for squeaks or rubbing. Watch for smooth rotation and no wobble. Recheck fasteners after the first short run. Safety note: Always unplug the dryer before working on it. For gas dryers, shut off the gas supply. If you are not comfortable handling gas lines, seals, or internal components, hire a qualified technician. Keep fingers and loose clothing away from moving parts during testing.
Common Symptoms
Squealing or scraping noises during tumbling, drum wobble or off-center rotation, slow or intermittent tumbling, or dryer that won’t tumble at all.
Common Causes
- Worn or torn drum felt seals allowing metal-to-metal contact
- Frayed, glazed, or broken drive belt causing slipping or no tumble
- Worn drum rollers, idler pulley, or rear bearing that damage felts and stress the belt

Helpful Repair Tip
Before disassembly, manually rotate the drum and listen for squeals or rubbing; mark the belt path with a piece of tape or take a photo so you can route the new belt exactly the same way.
Frequently Asked Questions
Do I have to replace the drum rollers and idler when I replace the felt and belt?
It's recommended. Worn rollers or a seized idler increase friction and wear the new felts and belt quickly. If rollers or the idler show noise, play, flat spots, or rough turning, replace them while you have the dryer apart.
Can I replace the felt without removing the drum?
Usually no. Properly seating the new felt requires access to the drum edge and bulkhead and often removal of the drum. Removing the drum also lets you inspect/replace rollers, the idler and clean lint — all important to prevent repeat failure.
