Replaced the upper-rack adjuster/roller assemblies with the new parts which are vastly superior to the original since the weight of the rack is supported by metal brackets instead of skinny plastic pins. The parts came quickly (next day) but there were no instructions. The video on this website is useful, but it starts with removing the newer design parts, not what we had. I found printed instructions on another web site. The other instructions followed a different (more difficult) sequence of assembly, but they included some details about the placement on the rack that was helpful. Videos are nice, but printed instructions plus a video would be even better. One other note, removing the rack from the dishwasher requires removing the end stops on the roller tracks. That's tricky, and the instructions for that were found in the owners manual "Press on the edge of the ridged area on the track stop while tipping the track stop toward the center of the dishwasher. This action releases a small retaining tab that locks the track stop to the track (see Track stop - left). NOTE: It is helpful to use 2 hands. Take special note of the orientation of the track stops."
