3 - TRANSFER CASE
NOTE: Vehicles built with a 4.0L engine and a man-
ual transmission use a damper weight on the trans-
fer case output shaft. Be sure to identify the
transfer case before proceeding.
(7) Install a new output shaft rear slinger with
Installer 8408, if the vehicle is not equipped with an
output shaft damper.
(8) If the vehicle is equipped with an output shaft
damper, install the output shaft damper as follows:
(a) Position the damper weight on the output
shaft. Start the damper onto the output shaft
chamfer, being careful to keep the weight square to
the output shaft. (Fig. 71)
(b) Position the driver portion of Installer 8422
(Fig. 72) onto the damper, making sure the legs of
the damper are positioned through the slots of the
damper.
(c) Thread the puller screw of Installer 8422 into
the output shaft by hand only. Make sure the
screw is fully threaded into the output shaft.
(d) Using a wrench to hold the pulling screw sta-
tionary (Fig. 73), turn the pulling screw nut until
the driver legs contact the rear face of the transfer
case rear retainer. When the legs contact the
retainer, the damper is properly positioned on the
output shaft.
(9) Install boot on output shaft slinger, or output
shaft damper, and crimp retaining clamp with tool
C-4975-A (Fig. 74).
