Hi Donald, welcome to Just answer .... I believe you are referring to part# ***** 597 and 597A or are you referring to 552 in attached schematic which needs to be replaced. In order to replace the dishwasher wheels you would need to remove the baskets, place the basket on flat surface and unscrew the broken wheels. Replace with new set of wheels compatible for your dishwasher model.
However, if it is dishwasher roller assembly which needs to be replaced then the tub needs to be removed before we go about replacing the runner rails.
You can find parts for your dishwasher here.________________________________________________________________________________________If you have further questions I will be pleased to assist you .. Please remember to RATE my answer Excellent or Good Service when you are satisfied....Thanks
Apologies, for your dishwasher model there are no screws holding the wheels, you need to insert the screwdriver to snap out the wheels from the tray. Also, note that wheel for baskets usually comes in set of 8 as well as single piece, I suggest you to but set of 8 as it would be economical.
I hope my solution helped you to resolve the issue with your appliance. If you have further questions I will be pleased to assist you.Please remember to RATE my answer Excellent or Good Service when you are satisfied. Thanks!
