Product review (5 stars): Better than original part
This part worked better than than the original axle part for my my GE Profile Triton Quiet Power III GSD5360F02SS dishwasher.  My existing wheels and axles were always falling off my lower tray since I moved into my house.  The new replacement part WD12X271 (diagram part 702 for my model) was no better.

I found that this part, which I originally bought to replace just my rear wheel axles, worked great on my existing (a little different) front wheels also.  All 6 of my lower wheels now have this improved axle, and the wheels have not fallen off yet (3 weeks).
