To answer your question about the front driveshaft, no, you didn't get
"freak drive shaft". Obviously Napa's book is leaving a lot to be
desired in the realm of accuracy. The front driveshaft on all the TJs
I've seen is always a CV driveshaft. Only the rear driveshaft comes
stock as a U-joint only driveshaft. And man, that front driveshaft
ain't cheap to replace if you damage it on the trail :( but at least
since it properly has the slip in the shaft rather than at the yoke,
an unmodified stocker can still remove it and drive home without
losing the transfer case fluid. ;-)

The CV on the TJ is to compensate for the low pinion D30. I always thought
it strange that they used a high pinion 30 on XJs & YJs, but then reverted
on the TJ.
