The reason I run a sealed joint is becuase they are solid where the greasable ones are hollow through the center to allow grease to pass to the caps.
The solid joints are stronger.
Now we are talking... I might look into these for this reason. I think the hollow section distorts in mine and allows for movement which then beats the roller bearings around.
Thanks! Ill keep you guys posted on mine. They go out pretty quick if I drive hard.
