The transfer case is used to provide a means of providing
power flow to the front axle. The transfer case also
provides a means of disconnecting the front axle,
providing better fuel economy and quieter operation when
the vehicle is driven on improved roads where four wheel
drive is not required. In addition, the transfer case
provides an additional gear reduction when placed in low
range, which is useful when difficult off–road conditions
are encountered.
A floor mounted shift lever is used to select the high–low
range. When four wheel drive switch has been turned on,
the four wheel drive indicator light is designed to come on
when the front axle has been engaged.
