The one roller broke on the top rack and I was worried that it would get worse because I have two teenagers in the house who don't know the word "gentle." I found AppliancePartsPros from a quick internet search, and navigated the web site to find the part I needed by using the model number of my dishwasher. Before place the order I watched the repair video associated with the part. The video clearly explains what to do and easy it should be. Within two business days of ordering, I received the part. On walking in the house from my commute home from work, I opened the package and took out the new roller assembly. I removed the old one, which was just a matter of twisting to dislodge it from the rack wires. I removed the end cap with the help of a small screwdriver. I inserted the new assemble into the rack wires - it requires a little twisting to work it in - then snapped down the lock tab. I then aligned the roller into the rail, replaced the end cap and it was done. Less than five minutes.
