How to Troubleshoot & Replace Whirlpool AP5988537 / W10822166 Track Assembly (Rh)

Replaced the tracks. You need to pull the dishwasher out for this since the screws holding them are on the outside. Not super complicated in my case since my dishwasher didn't require disconnecting water hose or power wires to pull out (there was enough slack behind). 

Removed the bottom rack from the dishwasher. Removed the 2 front plates at bottom of the dishwasher. Removed the two screws from the top of the dishwasher holding the dishwasher to the counter-top. Pulled the dishwasher out. Removed the 8 mm screws from the outside of the dishwasher-- 4 per side (Underneath the sound proofing). Pulled the old tracks and placed the new tracks into place and tightened the screws back up. Pushed the dishwasher back into place. Reinstalled the screws securing the dishwasher to the counter-top. Replaced the 2 front plates at bottom of the dishwasher. Replaced the bottom rack. 

Removed power, disconnected the inlet water hose, and drain hose, and pulled the unit out. I laid it on its side and replaced the drain pump. The only problem was receiving the parts from FedEX, The part did not arrive on time. 

Per instructions, pulled out dishwasher and removed four screws. Complete. 45 minutes. Luckily, all connections were long enough and did not need disconnecting. 

The fix was easy. It took about half an hour to do. 

Replaced both left and right tracks and support pieces which connect tracks to dish basket.
