Product review (4 stars): Read this for an Apollo 13 rack adjuster repair
Yes it is a shame that this part breaks. It stinks.

 Here is a quick repair to keep your dishwasher running.  Thread thin white zip ties through the bracket holes and the guide wheels. Carefully tighten to the point where the roller stills rolls.  The clips behind the roller axles must be temporarily removed then replaced to perform this temp repair. Trim the excess tag from the zip tie. I had to do 2 of these repairs before I was satisfied with the procedure.  If you have the skills this will keep you from hand washing dishes in 2014.
