INSTALLATION
(1) Apply a light coating of gear lubricant on the
lip of pinion seal. Install seal with Installer D-163
and Handle C-4171 (Fig. 10).
(2) Install yoke on the pinion gear with Installer
C-3718.
CAUTION: Do not exceed the minimum tightening
torque when installing the pinion yoke retaining nut
at this point. Damage to collapsible spacer or bear-
ings may result.
(3) Install a new nut on the pinion gear. Tighten
the nut only enough to remove the shaft end
play.
(4) Rotate the pinion shaft using an (in. lbs.)
torque wrench. Rotating resistance torque should be
equal to the reading recorded during removal, plus
an additional 0.56 N·m (5 in. lbs.) (Fig. 11).
(5) If the rotating torque is low, use Holder 6958 to
hold the pinion yoke (Fig. 12), and tighten the pinion
shaft nut in 6.8 N·m (5 ft. lbs.) increments until
proper rotating torque is achieved.
CAUTION: If the maximum tightening torque is
reached prior to reaching the required rotating
torque, the collapsible spacer may have been dam-
aged. Replace the collapsible spacer.
(6) Align the installation reference marks and
install the propeller shaft.
(7) Add gear lubricant to the differential housing,
if necessary. Refer to the Lubricant Specifications for
gear lubricant requirements.
(8) Install brake rotors and calipers. Refer to
Group 5, Brakes, for proper procedures.
(9) Install wheel and tire assemblies.
(10) Lower the vehicle.
