Product review (5 stars): Great replacement part
Bought this to replace the wheels on my existing GE dishwasher (which the axle and wheels either were broken or starting to melt). The replacement part is clearly an upgrade from what came with the dishwasher. These wheels are wide like the wheels that came with the bottom rack rear wheels (the front wheels are narrower for some reason). I used the replacement wide wheels on both the front and the back. The wide wheels work better on the front.

Also - note that you should also buy the roller axle (does not come with these replacement wheels). The replacement roller axle (part #WD12X10278) is better designed than what came with the original dishwasher as well. Securely hooks onto the basket, so no more wheels falling off.
