4581DD3003C LG Lower Rack Roller for Dishwashers, Fixes Rack Dragging or Derailing

🇺🇸 Matching U.S. Part Number: 4581DD3003C

4581DD3003C is a genuine LG lower-dishrack roller assembly used in select LG and Kenmore dishwashers. It replaces LG part numbers 4370FD3706C, 4581DD3003B and 4581DD9002B.

The roller attaches to the lower dishrack and allows the rack to move along the dishwasher tracks. A cracked, worn, loose or missing roller may contribute to a rack that drags, tilts, falls off the track or makes scraping and grinding noises.

Similar symptoms can also result from a bent rack, damaged axle, worn track, missing track stop, overloaded rack or another damaged roller. Inspect the complete lower rack before ordering.

Sold individually. Inspect all lower-rack rollers and order the required quantity. Confirm the roller position and original mounting style — other LG rack rollers may look similar but differ in fit.

Disconnect electrical power before servicing internal dishwasher components.

Is This the Right Part?

Confirm the complete model number before ordering. Similar rollers may differ in wheel diameter, axle diameter, clip style or mounting opening size.

Common Symptoms

• Lower rack drags or is difficult to open and close
• Rack falls off the track or derails when pulled out
• Rack tilts or sits unevenly when loaded
• Grinding or scraping noise when moving the lower rack
• Rack sits too low and contacts the lower spray arm
• Visible crack, flat spot or missing roller on the dishrack

Check Before Replacing

• Inspect all lower-rack rollers — a worn roller on one side can cause the entire rack to drag or tilt
• Check the rack axles and mounting points for bending or breakage
• Inspect the track ends and retaining stops — a missing stop allows the rack to slide off entirely
• Check for excessive rack loading or unevenly distributed dishes that may stress the rollers
• Verify spray-arm clearance — a rack sitting too low may indicate multiple failed rollers, not just one

Installation Notes

1. Disconnect electrical power to the dishwasher before beginning.
2. Pull the lower rack fully out of the dishwasher.
3. Photograph the existing roller position and mounting clip orientation before removing.
4. Compare the new roller with the original before installing — verify wheel size, axle diameter and clip style match.
5. Inspect the rack frame, axle and nearby rollers for additional wear or damage.
6. Reinstall the rack and test for smooth travel through the full range of motion.

Use a qualified technician when diagnosis or installation is outside your experience.
