The 247 is a full-time t-case. I removed the front shaft on a '99 WJ
when the CV in the shaft lost it's grease and the thing started to
rattle. It drove just fine. Mileage went up .5 mpg or so before I
put in a greaseable u-joint shaft.
But with the wrong lube in the t-case, I don't know if any damage to
the t-case will be avoided by removing the front shaft.

The OP's t-case is a NV247. It has a clutch that is engaged by a
gerotor. When the front and rear shafts move at different speeds,
the gerotor pumps fluid into the clutch-pack. This locks the two
shafts so that the free spinning shaft stops spinning and the
gripping shaft gets more power.
The OP's diffs also have gerotors and require a additive to the
full synthetic gear lube.
What gets me is that the additive at the local autoparts store says
it meets the DC spec # for the lube but then specificaly states that
it's not for Jeeps with Quadradrive. GAh...
