Product review (3 stars): Save your wheels! Wheels do not fit all versions
You didn't throw away those broken parts, did you? Did your rack wheel roll off down the heater grate when the axle broke? If I hadn't seen the description of how to remove the wheels and replace them with the old smaller wheels from my Kenmore (whirlpool), I might have tried sending the whole thing back. Not a difficult switch, but less than intuitive and not documented anywhere except an occasional mention of small wheels. So save your old wheels and you'll be sure to have the right size no matter what...
