Front Drive Actuator
(425)
NOTE: The actuator is not a serviceable compo-
nent. If it is defective, it must be replaced.
NOTE: The actuator will operate only when the
ignition switch is in the ON position.
The front drive actuator is located on the side of the
front drive input housing. With the engine stopped and
the ignition switch in the ON position, a momentary
"whirring" sound can be heard each time the front
drive selector switch is shifted. If no sound is heard,
see Electrical System. If the actuator runs constantly or
makes squealing or grinding sounds, the actuator must
be replaced.
REMOVING
1. Disconnect the connector on the actuator harness.
2. Remove the mounting cap screw from the drive-
shaft side of the actuator.

that all mounting surfaces are clean and free of
debris.
