Product review (5 stars): Makes your top rack better than new
My top rack always squeaked when rolling. One day it came crashing down and I saw the axles for the wheels had decomposed in the caustic environment of a dishwasher. Sears Parts Online showed the part in a diagram but had no part number or alternative. A call to the help desk was able to give me the part number. As you can see from the other reviews the original design was so bad it was doomed to fail with its all plastic body. This replacement, which fits many Kenmore Elite, Kitchen Aid, and Whirlpool models, uses stainless steel on the axle. The rest of the parts are just to replace height adjustor.

Assembly from the directions is near impossible due to the dark photographs provided without detail. Look for the YouTube video titled "Whirlpool, Kenmore, KitchenAid - Dishwasher Replacement Rack Adjuster Kit # W10712394 V-rail" You will see that it can assembled in minutes. You will definitely need a T-15 Torx screwdriver. A small flat screwdriver can help remove the old parts.

Once back in the washer it seems to roll better. No squeaks. The adjustment only seems to be high or low, but I always keep it in the high position. I am very happy to have the washer back to a condition better than new.
