Product review (5 stars): Dishwasher rack wheel replacements solves life long problem!
Winner of the Best Repair Value in the Kitchen. The lower dishwasher rack holds the big plates and heavy pans and invariably loses wheels. It is a simple replacement that permits the rack to roll smoothly over the door hinge gap. Missing a wheel, especially in the front, causes the rack to fall into the gap and get stuck or fall off the track. I can humbly say I didn't realize that's how the racks worked because, in my preference for older homes, the lower dishwasher racks never rolled smoothly. I thought I was supposed to lift them over the gap.  Great replacement product.
