Product review (5 stars): Cheap fix to save your sanity
My kitchenaid dishwasher door was squealing, and making me crazy.  These are a fast, easy swap - one screw per side, but you need to be able to reach back to the springs to clip them onto the new strings.  If you have long skinny arms, you might be able to do it without pulling the dishwasher out from under the counter.  I don't, so I did, and 20 minutes later it was back under the counter and now the door is silent!
