PINION GEAR/RING GEAR/
TONE RING
REMOVAL
NOTE: The ring and pinion gears are service in a
matched set. Do not replace the ring gear without
replacing the matched pinion gear.
(1) Remove differential from axle housing.
(2) Place differential case in a vise with soft metal
jaw protectors. (Fig. 44)
(3) Remove bolts holding ring gear to differential
case.
(4) Drive ring gear from differential case with a
soft hammer (Fig. 44).
(5) Use a brass drift and slowly tap the exciter
ring from the differential case.
(6) Mark pinion yoke and propeller shaft for
installation alignment.
(7) Disconnect propeller shaft from pinion yoke.
Tie propeller shaft to underbody.
(8) Using Yoke Holder 6719 to hold yoke, remove
pinion yoke nut and washer.
(9) Remove pinion yoke from pinion with Remover
C-452 and Wrench C-3281, shaft (Fig. 45).
(10) Remove pinion gear from housing (Fig. 46).
(11) Remove pinion seal with a slide hammer or
pry bar.
(12) Remove oil slinger, if equipped, and the front
pinion bearing.

(13) Remove front pinion bearing cup with
Remover C-4307 and Handle C±4171 (Fig. 47).
(14) Remove rear bearing cup with Remover D-159
and Handle C-4171 (Fig. 48).
(15) Remove rear bearing from the pinion with
Puller/Press C-293-PA and Adapters DD-914-95 (Fig.
49).
Place 4 adapter blocks so they do not damage
the bearing cage.(16) Remove the pinion depth shims from the pin-
ion gear shaft. Record the total thickness of the
depth shims.

INSTALLATION
(1) Apply Mopar Door Ease stick lubricant to out-
side surface of bearing cup. Install the pinion rear
bearing cup with Installer C-4204 and Handle
C-4171 (Fig. 50) and verify cup is seated.
(2) Apply Mopar Door Ease stick lubricant to out-
side surface of bearing cup. Install the pinion front
bearing cup with Installer C-4308 and Handle
C-4171 (Fig. 51) and verify cup is seated.
(3) Install pinion front bearing and oil slinger, if
equipped. Apply a light coating of gear lubricant on
the lip of pinion seal.
(4) Install new pinion seal with an appropriate
installer 8108 (Fig. 52).
NOTE: Pinion depth shims are placed between the
rear pinion bearing cone and pinion gear to achieve
proper ring and pinion gear mesh. If ring and pinion
gears are reused, the pinion depth shim should not
require replacement or adjustment. If the ring and
pinion gears are replaced refer to Adjustments to
select the proper thickness shim.(5) Place the proper thickness pinion depth shim
on the pinion gear.

(6) Install rear bearing and oil slinger, if equipped,
on the pinion gear with Installer D-389 and a press
(Fig. 53).(7) Install original solid shims on pinion gears.
(8) Install yoke with Installer C-3718 and Yoke
Holder 6719 (Fig. 54).
(9) Install the yoke washer andnewnut on the
pinion gear. Tighten the nut to 637 N´m (470 ft. lbs.).
(10) Check bearing rotating torque with an inch
pound torque wrench (Fig. 55). Pinion rotating torque
should be:
²Original Bearings: 1 to 3 N´m (10 to 20 in. lbs.).
²New Bearings: 2.8 to 5.1 N´m (25 to 45 in. lbs.).
(11) If rotating torque is less than the desired
rotating torque, remove the pinion yoke and decrease
the thickness of the solid shim pack if greater
increase shim pack. Changing the shim pack thick-
ness by 0.025 mm (0.001 in.) will change the rotating
torque approximately 0.9 N´m (8 in. lbs.).
(12) Invert the differential case.
(13) Position exciter ring on differential case.
(14) Using a brass drift, slowly and evenly tap the
exciter ring into position.
(15) Invert the differential case and start two ring
gear bolts. This will provide case-to-ring gear bolt
hole alignment.

(16) Invert the differential case in the vise.
(17) Install new ring gear bolts and alternately
tighten to 298 N´m (220 ft. lbs.) (Fig. 56).
CAUTION: Do not reuse ring gear bolts, the bolts
can fracture causing extensive damage.(18) Install differential in housing and verify gear
mesh and contact pattern.
(19) Install propeller shaft with reference marks
aligned.
