Product review (5 stars): Yay, my dishwasher is fixed
Perfect replacement for my broken string on my Kitchenaid KUDP01FL.  Moderately easy to install - helpful to have an extra person to relieve the tension on the string/spring when wrapping around the wheels.  The hardest part is actually just moving the dishwasher (i.e. getting all the screw holes to line back up on the top mounts and the baseplate and dealing with the sound insulation).  Fortunately I had enough slack in the drain and water lines so no issue there.  This replacement finally got rid of the annoying spring noise when opening/closing the door - now its super quiet, yay!  There are some good instructional videos on Youtube to help you out.
