Product review (5 stars): just the thing
GE had a design problem with the old wheels and studs. cheap crappy white wheels "held" to the rack with cheap crappy thin plastic arm type holders. These new bad boys are thicker stronger and have a way better pinch type holding system. Easy to install and we have not had any problems since putting them on. The rack glides in and out on the much sturdier, wider grey wheels. We replaced all the old with 8 new studs and wheels that cost about $50  bucks after all is said and done. Forget about GE stumping up for their design flaw. You gotta eat the whole amount. Still, $50 isn't so much to have one less frustration in our busy lives. Deffo glad I bit the bullet and changed them out.
