Product review (1 stars): Don't do it!
There is no reason to buy this part over and over. I was reading through the reviews and found a fix that works extremely well. Go to YouTube and type in "Kitchenaid W10350376 Rack Adjuster Fix" For less then $5 in parts from any local hardware store, and about 1/2 hour of your time, once started, you will never have to buy this rip off replacement part again. He uses nylon parts for his fix, I used metal just because it was easier to find. If you do use metal, make sure it is stainless steel. Have fun.
