A very good video of the repair. When you order the part, take a look at the video. It's a relatively easy repair. I've had to replace all four wheels on our old dishwasher. Like the video says, you may have to bend the rack a little to fit the wheel assembly in. Also, you'll have to remove the clips on the front of the railings. It was a little tricky so take your time and be careful not to break the plastic clips. As you press in the spot on the clip, just gently work the clip out of it's slot pushing or pulling upward. I used a flat head screwdriver to press the appropriate spot on the clip, since my finger pressure was not enough.
