I recently finished replacing the bearings and installed the snap ring afterward. I've noticed the snap ring isn't staying perfectly still, it shifts a little in the groove. I'm wondering if that's how it's supposed to be, or if it should be firmly seated with no movement at all. I made sure it was properly installed and seated in the groove, but now I'm second-guessing it. Has anyone else experienced this? I am just trying to make sure everything's right before I button things up completely
