Product review (5 stars): Fixed the problem!
Recent GE Dishwashers have problems with the wheels falling off the racks due to poor design, and low quality material.

These new clips are much stronger, and they securely attach to the rack. So far so good!
I wish I had ordered these earlier.  If your wheels are constantly falling off, these studs will do the trick.
As long as your wheels are not damaged, you can re-use them with these studs.
