LG Dishwasher Upper Dishrack Roller Parts — Models & Compatibility

The upper rack in your LG dishwasher should glide smoothly—when it starts binding, jumping the track, or making grinding noises, you're looking at worn dishrack rollers. This 4581DD3002A upper dishrack roller with axle assembly fits over 20 LG and Kenmore Elite dishwasher models, and it's the exact part you need when that top rack refuses to roll or keeps falling off its rails.
Is This the Right Part for Your Model?
Check your dishwasher's model number—you'll find it on the door frame inside the tub, usually along the left or right edge. Match it against the compatible models list below. This roller assembly replaces LG part numbers 4581DD3002A, 4581DD9001B, and cross-references to AP4437685 and PS3523050. If your model's in the LDS or LDF series from roughly 2008-2015, there's a good chance this is your part.
About This Replacement Part
This isn't just a wheel—it's a complete roller assembly with the axle included, which means you're replacing the entire wear point in one shot. The roller itself is made from durable plastic designed to handle the weight of a fully loaded upper rack, and the axle fits into the mounting brackets on both sides of your rack. LG dishwashers typically use four of these rollers per upper rack (two on each rail), and it's smart to replace all four at once since they wear at similar rates. When one fails, the others aren't far behind.
Why These Rollers Fail
Constant back-and-forth motion under load wears down the roller surface over time. You'll notice the rack becoming harder to pull out, or it'll stick at certain points and require extra force. Sometimes the plastic develops flat spots from sitting in one position too long, or the axle hole elongates and the roller wobbles. Heavy dish loads and hard water deposits accelerate the wear—crusty buildup on the rails creates friction that grinds down the roller surface faster than normal use.

Installation Overview
You don't need to disassemble the entire dishwasher for this repair. Pull the upper rack completely out of the unit—it lifts right off the rails once you've got it extended all the way. The old rollers pop out of their mounting brackets on the sides of the rack. Install the new roller assemblies by pressing the axles into the bracket holes until they snap into place. Check that each roller spins freely, then slide the rack back onto the rails. The whole job takes maybe 10 minutes if you're doing all four rollers.

How Many Do You Need?
Most LG upper racks use four rollers total—two per side, mounted on the rail ends. If only one roller is damaged, you can replace just that one, but it makes sense to do all four at once. They've all seen the same amount of use, and replacing them as a set ensures smooth rolling and prevents another service call in six months when the next one fails.
