Exactly what I was gonna' say. I seem to be going through them a fair bit (I've got 'em on all four corners). After I snapped one last night and bent the heck out of a cvd shaft, I'm trying something. Since the pins are captured by the bearings, and I only run the truck on a clay track, I'm pulling the set-screw and put some heavy-duty grease on the ends of the pins.
