NOTE: Each driveline section is designated either PARALLEL or
CROSSED, which is determined by the position of the yokes at
either end of the section. If the yoke lugs on the two yokes are
aligned, the section is PARALLEL.
If the yoke lugs are not aligned (opposite or crossed), the section
is CROSSED. Both sections are considered when determining the
phasing type.
