I replaced all of the roller wheels on the basket. The were very easy to snap off and to snap on the new ones. I placed the basket upside down on the counter to work on it. The basket rolls very easily now.
For the tine row, I left the basket in place in the dishwasher, and removed the tine row. It took about five minutes to figure out how to remove the two tine row holders and remove the tine row. It looks simple, but you have to pay attention to how the holders come out. It took just as long to install the tine row and the two holders. The front holder was the most difficult. Since I was only replacing one tine row, I had the second one, which is identical, to use as a model for reinstallation. It is a good thing that I was not replacing both rows. If I had removed both of them at the same time, I would probably have had more difficulty figuring out how the holders went in.
