Understanding the Problem
Worn drum rollers, worn or stretched drive belt, or damaged roller shafts are a common cause of loud squeaking, scraping, rubbing noises, or the drum not rotating smoothly on the LG DLEX3470V. Over time the roller bearings wear, shafts become grooved, or the belt frays — this increases friction and allows the drum to wobble, which produces noise and accelerates wear on other components. If left unaddressed, worn rollers and a failing belt can damage the drum or the rear drum bearing/support and may eventually cause the dryer to stop turning altogether. Repair is usually straightforward: replace the roller kit (rollers + shafts), inspect or replace the belt and check related parts like the idler pulley and rear drum bearing for wear while the dryer is open.
Common Symptoms
Loud squeaking or scraping noises during rotation, drum wobble, belt slippage or fraying, burning rubber smell, or drum failing to spin.
Common Causes
- Worn/deteriorated drum rollers or roller bearings causing rough rotation
- Stretched, frayed, or snapped drive belt reducing drum traction
- Grooved or seized roller shafts, misaligned rollers, or lint buildup accelerating wear

Helpful Repair Tip
Manually spin the drum with the dryer off — listen for roughness and feel for resistance or wobble; visual inspection of the belt for fraying and the rollers for side-to-side play confirms the parts to replace.
Frequently Asked Questions
How do I know whether to replace rollers, belt, or both?
If the drum squeaks or feels rough when spun by hand, the rollers are likely worn; inspect them for rough bearings, flat spots or side-to-side play. If the belt is frayed, glazed, cracked, or loose, replace it. Because rollers and belts wear together and repairs require opening the cabinet, it's cost-effective and recommended to replace both at the same time and check the idler/bearing for damage.
How long does replacing drum rollers and the belt take and can I do it myself?
A DIY replacement typically takes 45–90 minutes for someone comfortable with basic appliance repair: unplug the dryer, remove the top and/or front panel, tilt the drum to access and replace rollers, swap the belt, and reassemble. Have a socket set, screwdrivers, and a putty knife ready. If you’re not comfortable or if the rear bearing or bulkhead is damaged, consider a professional — and always unplug the dryer before starting.
