Looked the repair up on Youtube. Purchased the slides and rack adjusters from APP and installed myself (at 73 years old). Instructions and repair went as illustrated but pulling the dishwasher out took more time due to under counter restrictions. Hint (not in video), when repair is complete disconnect dishwasher drain hose from disposal and run a couple of rinse cycles into a bucket to remove bearings that fell into pump without damaging your disposal. Not technically challenging if you can follow instructions but some physical effort required.
