(14) Remove rear bearing cup from housing (Fig.
77) with Remover C-4307 and Handle C-4171.
(15) Remove collapsible preload spacer (Fig. 78).
(16) Remove rear bearing from the pinion with
Puller/Press C-293-PA and Adapters C-293-42 (Fig.
79).
(17) Remove depth shims from the pinion gear
shaft and record shim thickness.
INSTALLATION
NOTE: A pinion depth shim/oil slinger is placed
between the rear pinion bearing cone and the pin-
ion head to achieve proper ring gear and pinion
mesh. If ring gear and pinion are reused, the pinion
depth shim/oil slinger should not require replace-
ment. Refer to Adjustment (Pinion Gear Depth) to
select the proper thickness shim/oil slinger if ring
and pinion gears are replaced.

(1) Apply Mopar Door Ease or equivalent lubricant
to outside surface of pinion bearing cups.
(2) Install pinion rear bearing cup with Installer
C-4308 and Driver Handle C-4171 (Fig. 80) and ver-
ify cup is seated.
(3) Install pinion front bearing cup with Installer
D-129 and Handle C-4171 (Fig. 81) and verify cup is
seated.(4) Install pinion front bearing and oil slinger, if
equipped.
(5) Apply a light coating of gear lubricant on the
lip of pinion seal. Install seal with an appropriate
(Fig. 82).
(6) Install depth shim on the pinion gear.
(7) Install rear bearing on the pinion gear with
Installer 6448 and a press (Fig. 83).

(8) Install anewcollapsible preload spacer on pin-
ion shaft and install pinion gear in the housing (Fig.
84).
(9) Install yoke with Installer C-3718 and Spanner
Wrench 6958 (Fig. 85).(10) Install the yoke washer and a new nut on the
pinion gear and tighten the pinion nut until there is
zero bearing end-play.
(11) Tighten the nut to 298 N´m (220 ft. lbs.).
CAUTION: Never loosen pinion gear nut to decrease
pinion rotating torque and never exceed specified
preload torque. If preload torque or rotating torque
is exceeded a new collapsible spacer must be
installed.
(12) Using Spanner Wrench 6958 and a torque
wrench set at 380 N´m (280 ft. lbs.), (Fig. 86) slowly
tighten the nut in 6.8 N´m (5 ft. lbs.) increments
until the rotating torque is achieved. Measure the
rotating torque frequently to avoid over crushing the
collapsible spacer (Fig. 87).
NOTE: If more than 380 N´m (280 ft. lbs.) torque is
required to crush the collapsible spacer, the spacer
is defective and must be replaced.

(13) Check bearing rotating torque with a inch
pound torque wrench (Fig. 87). The pinion gear rotat-
ing torque should be:
²
Original Bearings: 1 to 2.25 N´m (10 to 20 in. lbs.).
²New Bearings: 2.8 to 4 N´m (25 to 35 in. lbs.).
(14) Invert the differential case and start two ring
gear bolts. This will provide case-to-ring gear bolt
hole alignment.
(15) Invert the differential case in the vise.
(16) Installnewring gear bolts and alternately
tighten to 129-142 N´m (95-105 ft. lbs.) (Fig. 88).
CAUTION: Never reuse the ring gear bolts. The
bolts can fracture causing extensive damage.
NOTE: If equipped with Veri-LokTdifferential install
oil feed plenum and side bearing.
(17) Install differential in housing.
CAUTION: When installing a Vari-lokTdifferential
(Fig. 89), the oil feed tube must point to the bottom
of the housing. If differential is installed with the oil
feed tube pointed toward the top, the anti-rotation
tabs will be damaged.
(18)
Verify differential bearing preload, gear mesh
and contact pattern. Refer to Ajustments for procedure.
(19) Install differential cover and fill with gear
lubricant.(20) Install the propeller shaft with the reference
marks aligned.
(21) Remove supports and lower vehicle.
