Product review (5 stars): Vast Improvement from OEM all Plastic Assembly
Over the course of 3 years I have replaced 3 of the all plastic OEM upper dishwasher rack wheel assemblies (i.e., the assembly this item replaces).  I followed the advice of one Amazon reviewer and used a high temperature epoxy to glue the plastic prongs on the plastic assembly - I think that was a good suggestion and very likely extended the life of the plastic assembly.  However, after 2+ years the epoxy kluge was failing and one of the plastic prongs broke off.  Then I found this "new" part.  It looks significantly more substantial and does not appear to have the weaknesses of the all plastic assembly.  I installed it today, I found the directions were good but the pictures were of poor contrast and difficult to see the necessary detail.  The disassembly and installation of this new part on both sides of the dishwasher rack took less than 30 minutes.  Time will tell if this fixes the design flaws but I am very encouraged by the improvements in this part.  Good luck.
