The plastic wheels kept falling off the bottom rack of the dishwasher

The old wheels and attachment brackets were easily removed since they were always falling off. I ordered all new brackets and wheels, but it turns out I didn't need new wheels. If your original wheels are in good condition, they are the same size as the new ones and fit the new brackets. The new attachment brackets are built differently than the ones that came with the dishwasher, but (a good thing considering the originals only lasted 1 1/2 years). The new brackets and wheels snapped together and snapped into place on the dishwasher in minutes--no tools were needed. It took longer to cut the parts out of the packaging than to install them. The bottom rack now rolls out like it did when it was brand new. Definitely worth the few dollars in parts.
