TRANSFER CASE 7D-3
General Description
RUW34DLF000701
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.
Use the 4WD switch on the center cluster panel to
select the drive range. The 4WD indicator lamp will be
lit when 4WD is selected.
