Good idea. I previously tightened the driver retaining ring, but I didn’t think to check that the flat spot on the driver was aligned with the tube.
Re: white o-ring. My first thought was that it was to keep the clip tight. But then I noted in CRX’s review that the o-ring was around the inner tube. 
It seems I have a white o-ring around my inner tube too and between the clip and the body.
