4WD → 2WD
When the transfer shift control lever is shifted from the 4WD (4H or 4L) to the 2WD (2H) position, the 4WD con-
troller activates VSV1 and the intake manifold vacuum is applied to the chamber "A" in the hub housing. As the
slide gear is shifted to the wheel side by the vacuum force and disengaged from the outer gear, rotation of the
front wheel hub is not transmitted to the front axle shaft.
