This was a simple fix that involved replacing the roller studs (axles) that held the wheels on the bottom dishwasher rack. The replacement pieces appeared to be of better design than the originals. GE made some upgrades. The wheels easily snapped on to the axle and then a clip held the axle tightly in place on the dishwasher rack. My wife is happy because she no longer has to worry about the wheels falling off when she opens the dishwasher! Easy and affordable fix.
