2 Rack Rollers snapped

First I needed to remove the end caps on the sliding metal rails which hold the rack rollers. This was the most challenging part of the repair and the largest amount of time was devoted to getting them out without breaking them. Once these were off, I slid the rack out, removed all of the rollers and replaced them with the new ones. I guided the rollers back into the metal rails and then began trying to get the end caps back on. Again - dealing with these was the most challenging, but with patient work, they snapped back in. It was helpful to have a screwdriver to 'persuade' the end caps on and off.
