I'm not a mechanic, but my understanding of part-time 4wd used on our
Dakotas, if used on dry pavement will
damage the drive-line due the fact that the front and rear wheels are locked
together and
rely on slippage (ie. slippery roads) to relieve the torque buildup.
This is different than 'all wheel drive' vehicles which all have some sort
of fluid (or other)
differential between the front and rear wheels.
I'm sure one of the list's experts can explain this in more detail.
