If you start with the center of the knuckle on the right edge of the picture and then proceed down the casting seam to the center line of the torque tube, when you arrive at the knuckle on the left the extension of the line we've been drawing appears to pass well below the bearing circle, let alone being near its center. Sure looks to me that these joints are well out of phase. Pull it apart as described and line it up, ah yes silence on the drive.
