My new parts came in very promptly. Thank you very much, Appliance Parts Pros! I was expecting to have to slide the dishwasher out from under the counter to access the back side of the four mounting brackets. However, instead I decided to carefully rotate each side track downward to detach from the side mounting brackets and it worked great. In order to reduce the chances of damaging existing mounting bracket tabs during install of new side tracks, I first applied a small amount of silicon grease on each side track in vicinity of the mounting bracket tabs. I then laid the bottom of the new side tack into bottom side of the existing mounting tabs and CAREFULLY applied a pair of vice grips to the upper mounting tab arm to gently increase space between mounting tabs. After ensuring that the track backside slots were in the correct location, I carefully rotated the new track upward snapping it into place.
