Daniel L Kent , WA March 24, 2015 Appliance: KitchenAid Undercounter Dishwasher KUDS30IXBL4 Kitchenaid Dishwasher Kuds30ixbl4: On kitchen aid dw axles for the wheels on the top rack broke allowing the wheels to come off. How to replace Belt-Hd Commercial C. Used Whirlpool AP5956100 Adjuster kit. It replaces both sides so you just need one kit. The main frame on these are stainless steel instead of the cheap plastic one that came on the Kitchen Aid from the factory. also the wheel axles are replaceable on the new ones (or at least look like they are). Removed old broken parts and installed new per instructions. Make sure you put the clips UNDER the middle bar not over it. I had to remove one side and one of the small keeper tabs broke on the upright plastic part when I depressed it to remove the part. since there are 2 tabs and no load on them it should be ok. You will need a # 15 torx bit and maybe a screwdriver to release the tabs on the old parts to remove them. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
