but that is just my thought
4 wheel drive High and 4 wheel drive Lock are two different things.
4 lock on the transfer case is to lock the output drive shafts together and eliminate the differential in the transfer case of full time 4WD systems. It doesn't have anything to do with the axle shafts locking together. You don't want to use it on high traction surfaces because of the potential for drive line bind that could result in damage to the transfer case, ie Dry paved Roads. Setting the case in the 4 lock locks the front and rear outputs together much like your air lockers.
For variable driving conditions, the 4WD AUTO mode
can be used. In this mode, the front axle is engaged, but
the vehicle’s power is sent to the rear wheels. Four-wheel
drive will be automatically engaged when the vehicle
senses a loss of traction. Because the front axle is engaged,
this mode will result in lower fuel economy than
the 2WD mode. When additional traction is required, the transfer case
4WD LOCK and 4WD LOW positions can be used to lock
the front and rear driveshafts together forcing the front
and rear wheels to rotate at the same speed. This is
accomplished by rotating the 4WD Control Switch to the
desired position. Refer to “Shifting Procedure” for specific
shifting instructions. The 4WD LOCK and 4WD
LOW positions are designed for loose, slippery road
surfaces only. Driving in the 4WD LOCK and 4WD LOW
positions on dry hard surfaced roads may cause increased
tire wear and damage to the driveline components.
