Understanding the Problem
What the roller wheel is and why it fails: The dryer drum rollers (support rollers) are small wheels that support the drum on rear and sometimes front shafts so the drum turns smoothly. Over time the rollers' bearings wear, the wheel cracks, or lint and heat damage the plastic, causing squealing, grinding, rumbling, or drum wobble. Replacing worn roller wheels restores quiet, smooth operation. Step-by-step diagnosis and repair: 1) Confirm the symptom: Run the dryer empty on a no-heat or timed cycle. Listen for loud squeal/grind, intermittent thumping, or rubbing noises; watch for drum wobble when it spins. Check for burning/plastic smell. 2) Safety first: Unplug the dryer or switch off the breaker. Turn off gas supply on gas models. Allow the dryer to cool if recently used. 3) Access the rollers: Most LG front-loaders require removing the top panel and front panel (or the lower service panel) to access the drum. Remove the lint filter, then remove the retaining screws behind the lint trap and any screws securing the top. Lift or slide the top forward. Remove the front panel screws, disconnect door switch wiring as needed, and carefully lift the front off so you can pull out the drum. 4) Inspect rollers and shaft: With the drum removed, locate roller wheels (usually 2–4 depending on model). Spin each roller by hand. Check for roughness, binding, excessive side play (wobble), cracked wheels, or worn bearings. Also inspect the rear drum bearing (if your model has one) and the shaft for scoring. 5) Check belt and idler: While drum is out, inspect the drive belt for glazing, fraying, or cracks. Check idler pulley for free smooth rotation. 6) Order replacement parts: Replace any roller that is noisy, loose, or cracked. It’s best to replace the entire set (all rollers) and the rear bearing if worn. Confirm correct part numbers for your dryer model (see Parts section below). 7) Replace roller wheels: a) Remove the old rollers by sliding them off their shafts or removing their mounting nut/screw, depending on design. Keep note of washer/spacer orientation. b) Clean the shafts and housing of lint/dust. Lightly wipe any rust or debris off the shaft. c) Install new rollers in the same orientation with the same washers/spacers. Secure any cotter pins, nuts, or bolts to the original tightness (hand-tight plus a quarter turn for small nuts); do not overtighten — the roller must spin freely. d) If your model has a rear drum bearing (felt or roller), replace it if worn. 8) Reinstall drum and belt: Place the drum back into the cabinet over the rollers. Re-thread the drive belt around the drum grooves and around the motor/idler pulley in the correct orientation. Rotate the drum by hand to verify smooth movement and correct belt tracking. 9) Reassemble the dryer: Reconnect any wiring you removed (door switch), reinstall the front panel, secure screws, replace the top panel and lint filter. 10) Test run: Plug the dryer back in, run an empty cycle and listen for noise. Observe drum rotation for wobble and make final adjustments if belt has shifted. Practical tips during the job: Mark belt orientation before removal so you reinstall it the same way; take photos during disassembly to help reassembly. Replace rollers in matched sets — new rollers with old ones will cause uneven wear and noise. Safety note: Always disconnect electrical power before working on the dryer. If you are uncomfortable working with the appliance, call a qualified technician. Avoid leaving lint buildup — it's a fire hazard.
Common Symptoms
Loud squealing or grinding noise during spin, intermittent thumping/slapping, visible drum wobble, rubbing or burning plastic smell, uneven drum rotation.
Common Causes
- Worn or seized roller bearings causing rough spinning
- Cracked or flattened roller wheel from heat or age
- Excessive lint buildup or debris preventing roller rotation
- Worn rear drum bearing or damaged drum shaft causing misalignment

Helpful Repair Tip
Lift the drum slightly and spin it by hand: a bad roller will feel rough, bind, or have noticeable side-to-side play; a good roller will spin freely and quietly.
Frequently Asked Questions
How long does it take to replace LG dryer roller wheels?
For someone with basic tools and experience, replacing the roller wheels typically takes 45–90 minutes. If you're unfamiliar with dryer disassembly, allow extra time to take photos and follow the steps carefully.
Can I replace just one roller wheel or should I replace all of them?
It's best to replace all roller wheels (a kit) at once. New rollers and old rollers will not wear evenly and the remaining old rollers will likely fail soon after, so replacing the set gives longer quiet operation and better drum alignment.
