Product review (5 stars): should have done this repair first would not have need all those zip ties
I have fixed my Kitchen-aid/whirlpool dish washer top rack multiple times (5 or more).  This kit solves the problem of  brittle plastic parts.  Watch a YouTube video as no instructions are included.  It took less than ten minutes to change the rack wheel assemblies.  No more zip ties holding everything together.  Much  less expensive on Amazon then Sears parts.
