Wheel broke on Rack Adjuster

I read the other fellow's report and was sceptical of replacing this part, that quickly, without breaking any of the other plastic pieces involved in the process. Decided to try it and only ordered the one necessary part (which came in two days). I was able to detach and reuse all surrounding plastic hardware while installing the new rack adjuster (~$24), and did it all with just one small-sized screwdriver. It was less than 15 minutes as the other fellow said.
