How to Replace LG Dryer Drum Support Rollers

The drum support rollers are small wheels on the rear bulkhead that carry the drum's weight as it turns. Their bearings wear with time, and as they do you hear a rhythmic squeak, a thump from a flat spot on a roller, or a growing rumble. The failure is progressive — the noise creeps up over weeks until it is impossible to ignore — so once you have confirmed the rollers, replace them before they score anything.

Tools, Parts, and Safety#

Gather a Phillips #2 screwdriver, a 5/16-inch nut driver, snap-ring pliers or a flat screwdriver, and work gloves. The part is an LG drum roller kit matched to your model, containing the rollers, shaft washers, and clips. On safety: Unplug the dryer. The drum weighs 50-70 lbs. Support it properly during removal. Budget 45-60 minutes.

Step 1 — Remove the Panels and Drum#

Take off the top and front panels and disconnect the door switch. Release belt tension at the idler pulley, slip the belt off the motor pulley, and lift the drum out through the front. If you have not been inside this dryer before, follow the model's disassembly guide for the exact panel sequence.

Step 2 — Reach and Check the Rollers#

With the drum out, the rear support rollers are exposed on the rear bulkhead, riding on shafts and turning freely. Spin each one by hand: a healthy roller turns smoothly and quietly, while a worn one feels stiff or wobbly, squeaks, or shows a flat spot.

Step 3 — Remove the Old Rollers#

Each roller is held on its shaft by a retaining clip (a C-clip or E-clip) or a triangular washer. Pop the hardware off with snap-ring pliers or a flat screwdriver, slide the old roller off, and remove the thrust washer that sits between the roller and the bulkhead.

Step 4 — Install the New Rollers#

Wipe each shaft clean of old grease and grit. Fit the thrust washer first, slide on the new roller, and lock it with the retaining clip. Confirm each new roller spins freely with no wobble. If the roller is not pre-lubricated, add a dab of high-temperature bearing grease to the shaft.

Step 5 — Reinstall the Drum and Test#

Set the drum back in, route the belt, and rebuild the panels. Run a no-heat tumble and listen — the drum should turn smoothly with no squeak, thump, or rumble. A short break-in over the first 2-3 cycles may make minor noise as the new rollers seat.

LG-Specific Roller Notes#

Most residential LG dryers (the DLE and DLG series) use two rear rollers; higher-capacity 9.0 cu ft units may use four for extra support. LG rollers use a sealed bearing that cannot be re-lubricated, so once the bearing wears, replacement is the only fix. The shafts themselves are pressed or welded into the rear bulkhead; if a shaft shows a worn groove where the bearing rides, the whole bulkhead would need replacing — but that is rare and signals long-term neglect, since a normal shaft stays smooth. After reassembly, check that the drum sits at the right height against the front felt seal, contacting it evenly all the way around. New rollers that are slightly larger than the old ones can hold the drum a touch high at first; that settles within the first few cycles as the felt compresses.

Troubleshooting#

If a squeak comes back after the swap, the front drum glides or the idler pulley bearing may be the real source rather than the rollers. Persistent thumping means a clip is not fully seated or a roller is wobbling on its shaft. A drum that will not turn freely usually has a roller installed backward or a missing thrust washer binding it.
