Whirlpool Dishwasher Axle, Roller, Pulley Parts

The Lower Dishrack Roller Assembly is an OEM part for Whirlpool dishwashers. As an integral component, the lower dishrack roller assembly supports smooth movement and positioning of the lower dishrack. Its precision ball bearings allow for effortless extension and retraction of the lower rack.

Causes of a bad lower dishrack roller assembly can include wear and tear of bearings over time, stripped or damaged rails, or failure of rollers due to excessive loading.  

Symptoms of a bad lower dishrack roller assembly include:

• Difficulty extending or retracting the lower dishrack  
• Noisy or stuck operation of the lower rack
• Rack failing to remain securely in place during wash cycles
• Dishes shifting or falling during wash due to uneven support

This OEM Whirlpool part is also compatible with KitchenAid, Jenn-Air, Amana, Kenmore, and some Maytag and GE dishwashers. 

This tub wheel mounts to the dishwasher's inner tub wall and guides the rack as it slides in and out. Replacing a worn wheel restores smooth rack movement and helps prevent binding, derailing, and scraping.

• Attaches to the tub to support and guide rack travel
• Helps keep the rack aligned on its tracks for smooth operation
• Typical failure symptoms: rack hard to slide, rack jumps off track or tilts, scraping/grinding noises, cracked or missing wheel
• Restores proper glide and reduces strain on rack components

• Disconnect power and water supply before servicing the appliance
• Remove the rack for access; release the old wheel's clip/fastener from the tub and install the new wheel
• Ensure the wheel spins freely and the rack moves smoothly end-to-end
• Inspect other wheels and related hardware and replace as needed for even wear

Note: Shaft has been revised by the factory and the spring is no longer used.

A replacement transport wheel assembly that restores smooth rolling for the appliance's transport/support system, making it easier and safer to move or position the unit. Designed to match the OEM fit and function. What it does:

• Replaces a cracked, worn, or missing transport/support wheel that can prevent smooth rolling or cause scraping
• Helps the appliance move without binding, catching, or excessive noise during transport or repositioning
• Restores stable support for the component that relies on this wheel to roll or track properly
• Useful when the wheel is visibly damaged, detached, or causing uneven movement

• Disconnect power and follow manufacturer safety instructions before servicing
• Access may require removing an access panel or trim; use hand tools and keep fasteners organized
• Inspect surrounding parts for related wear when replacing the wheel

This bearing helps the appliance's rotating assembly turn smoothly and reduces metal-on-metal wear for quieter, more reliable operation. Replace a worn bearing to address noise and movement issues that affect performance. What it does:

• Supports the drum or tub shaft so it rotates with minimal friction
• Reduces grinding, rumbling, or squeaking noises from the rotating assembly
• Helps prevent excessive wobble or vibration during spin cycles
• Limits metal wear that can lead to leaks or further component damage

• Disconnect power and water before starting work
• Inspect surrounding seals, shafts, and mounting surfaces for wear while replacing the bearing
• Use correct tools and replacement hardware; follow OEM instructions for torque and alignment
