Using a needle bearing in that application is like putting lipstick on a pig- - - - -there's no real reason to do it, and the result might have some real downsides. There are too many moving parts that can fail in a roller bearing setup, so I can't imagine any good reason to substitute it for the old reliable oilite bushing that has worked for decades in untold millions of vehicles.
