Drive shaft phasing is considered correct when the yokes on the two shafts are in which position?

Drive shaft phasing means aligning the two U-joints so their yokes line up in the same plane. When the yokes are in the same plane, the speed fluctuations produced by one joint are canceled by the other, yielding smoother rotation and less vibration and wear. If the yokes are in perpendicular or opposite planes, the fluctuations don’t cancel, causing vibration. A position like “one above the other” isn’t a proper phasing arrangement, so it won’t provide the needed alignment.
