Mike S Erlanger , KY July 04, 2014 Appliance: Maytag Dishwasher MDB8600AWQ Maytag Dishwasher Mdb8600awq: Wheel broke on rack adjuster assembly. How to replace Rack Adjuster Assembly. I ordered the rack adjuster assembly. I only needed the wheel, not the entire assembly, and when I recieved the assembly, I found the wheels are now riveted on, not held there by screws. The assembly was a perfect replacement, You will need a small star bit (T10) to do replacement. Part arrived in two days. This is the second time I've ordered parts from AppliancePartsPros.com...great company. 15 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
