7D-12 TRANSFER CASE
Removal
NOTE: Before removing transmission and transfer
assembly from vehicle, change the transfer mode to
2W D using the 4W D push button switch on dash panel.
1. Disconnect battery ground cable.
2. Raise and support vehicle with suitable stands. Drain
transfer case fluid.
3. Remove rear propeller shaft and front propeller shaft.
NOTE: Apply alignment marks on the flange at both front
and rear sides.
4. Disconnect harness connectors and clip.
Connector: transfer switch, 2W D-4W D actuator,
speed sensor.
NOTE: Avoid turning the vehicle ignition switch to the ON
position when the 2W D-4W D connector is removed
(battery connected).
If the ignition switch must be turned to the ON position,
the controller must first be removed (memory must be
cleared because the CHECK 4W D INDICATOR will
light).
5. Remove transfer case assembly from the vehicle.
Installation

1. Apply a thin coat of molybdenum disulfide grease to
the input shaft spline as shown in the figure.

Speed sensor
Revolutions of the rear output shaft are decreased and taken
out by the speed/drive/driven gears installed in the transfer
case. The number of revolutions is detected with a speed
sensor.
About 4/3 pulses per revolution of the shaft are output.

4WD switch
The 4W D switch detects the movement of the shift rod driving
the 4 ×2 - 4 ×4 sleeve.
PUSH open is achieved with the PUSH open switch when the
shift rod is at the 4 ×2 position.
