Product review (5 stars): Good product
There is no one less equipped to repair an appliance than me, and I was actually able to fix my KitchenAid broken upper rack wheels with this kit.  I found a YouTube video showing what to do, and spent about two hours bumbling through the instructions.  Yay!  Success!  My dishwasher is KUDS301x.  Someone less fumble- fingered than me could probably swap out the wheel assemblies in 15 minutes.  The new assembly seems a lot sturdier than the one which came with the dishwasher.
