Product review (5 stars): Replaced my original plastic adjuster then kept breaking.  I included some instructions that make sense and pictures to help.
Used this kit to replace my Kicthenaide dishwasher plastic wheel axle part that kept breaking.  Worked perfect!!  5 mins install.

This kit works for tons of dishwasher models so check the pictures accordingly.  Here's my breakdown on how to replace it as the instructions provided were useless.

Instructions:

1. Remove top tray and set on counter by folder end rail stops over to allow removal
2. Pry off old plastic adjuster on LH side using flat head screwdriver and discard.
3. Count 4 bays from front and slide up metal flat up and twist to fit (wheels out)
4. slide the braces between the wires and slide down onto both metal frame shorter fingers.  slide and lock in place
5. slide on the large adjuster under the adjuster tabs but don't push it all the way down yet
6. fit the thumb adjuster into the round opening near the top of the adjuster and push into place.
7.slide the adjuster down with the thumb mechanism in place until the wires fit properly into the slots on the top and middle
8.fit cover into top slot then push in to place and install both screws with a tor T-15 driver bit. (kit comes with an adapter if you need it)

Do the same procedure for the RH side and install back into your dishwasher and your done!  took me 5 mins including my toddler grabbing parts and tools and running off with them.
