The wheels kept falling off the right side of the bottom rack; it was extremely annoying. We basically had to lift the bottom rack to get it in and out of the dishwasher.

I removed the old wheels & studs on the right side of the bottom rack of the dishwasher, and I gleefully THREW THEM ALL OUT! HA HA!

Then I put the nice new rollers on the studs, and then I put them on the rack.

Helpful hints for others beleaguered by this design problem:

1) Be sure to get new studs - that's the part that kept causing the wheels to fall off

2) Put the rollers on the studs before putting them on the rack. (Another user on this site noted that, and it was very helpful).

3) P.S. Very prompt shipping, great service - I will definitely use this company again. And thanks to whoever dropped a cheerful Christmas candy into the box!!
