In the XJ (you have no CV joint in the rear driveshaft), the rear pinion
should be set almost parallel to the output shaft of the transfer case. I
say almost, because the rear pinion should be pointed a bit lower (0.5 - 1
degrees) than the TC output shaft. That is because under load the rear
pinion will rotate a bit upwards, so you have to compensate for this by
adjusting the rear pinion a bit lower.
In the XJ driveshaft vibrations are less noticeable than TJs, because the
drive-shafts are much longer, and the change in angles with the lift is
smaller.
The axle vibrations feel similar the difference of going from street tires
to muds. If you already have mud tires, you may not feel the vibrations at
all, so it would be better to put a set of old street tires if you have
and
adjust the pinion angle by trial-and-error, until you find the correct
angle
that gives the smoother ride.
In the front axle, the pinion should be almost parallel to the driveshaft,
again 1 degree lower that the parallel position, to permit the U-joint
bearings to rotate for proper lubrication. If you noitice death-wobble,
you
may want to lower to front pinion a bit more to increase the caster angle.
