Dodge Durango (DN). Manual — part 223
(4) Separate the propeller shaft from the compan-
ion flange and using suitable wire, tie the propeller
shaft to the vehicle underbody.
(5) Rotate the pinion gear three or four times.
(6) Measure the amount of torque necessary to
rotate the pinion with a (in. lbs.) dial-type torque
wrench (Fig. 18). Record the torque reading for
installation reference.
(7) Install socket head bolts into two of the
threaded holes in the companion flange, 180° apart.
(8) Position Holder 6719 against the companion
flange and install a hex head bolt and washer into
one of the remaining threaded holes. Tighten the bolt
and washer so that the Holder 6719 is held to the
flange.
(9) Hold the flange with Holder 6719. Remove the
pinion nut.
(10) Remove the companion flange with Remover
C-452 (Fig. 19).
(11) Remove the pinion from housing (Fig. 20).
Catch the pinion with your hand to prevent it from
falling and being damaged.
(12) Using a suitable pry tool, or a slide hammer
mounted screw, remove the pinion seal.
(13) Remove oil slinger, if equipped, and front pin-
ion bearing.
(14) Remove the front pinion bearing cup with
Remover D–103 and Handle C–4171 (Fig. 21).
(15) Remove the rear bearing cup from housing
(Fig. 22). Use Remover 8401 and Handle C–4171.
(16) Remove the collapsible preload spacer (Fig.
23).
(17) Remove the rear bearing from the pinion with
Puller/Press C-293-PA and Adapters C-293-42 (Fig.
24).
Place 4 adapter blocks so they do not damage
the bearing cage.

(18) Remove the depth shims from the pinion
shaft. Record the thickness of the depth shims.
INSTALLATION
(1) Apply Mopar

REMOVAL AND INSTALLATION (Continued)
(2) Install
the
pinion
rear
bearing
cup
with
Installer D-145 and Driver Handle C–4171 (Fig. 25).
Ensure cup is correctly seated.
(3) Apply Mopar
t Door Ease, or equivalent, stick
lubricant to outside surface of bearing cup.
(4) Install the pinion front bearing cup with
Installer D–129 and Handle C–4171 (Fig. 26).
(5) Install pinion front bearing, and oil slinger, if
equipped.
(6) Apply a light coating of gear lubricant on the
lip of pinion seal.
(7) Install seal with Installer C-3972-A and Handle
C–4171 (Fig. 27).
NOTE: Pinion depth shims are placed between the
rear pinion bearing cone and pinion gear head to
achieve proper ring gear and pinion mesh. If the
factory installed ring gear and pinion are reused,
the pinion depth shim should not require replace-
ment. If required, refer to Pinion Gear Depth to
select the proper thickness shim before installing
rear pinion bearing.
(8) Place the proper thickness depth shim on the
pinion shaft.
(9) Install
the
rear
bearing
and
slinger,
if
equipped, onto the pinion shaft with Installer 6448
(Fig. 28).
(10) Install a new collapsible preload spacer onto
the pinion shaft (Fig. 29).
(11) Install the pinion in the axle housing.
(12) Seat the companion flange on the pinion shaft
with Installer C-3718 and Holder 6719.
(13) Remove the Installer C-3718 and install the
new pinion nut.
CAUTION: Do not exceed the minimum tightening
torque when installing the companion flange at this
point. Damage to the collapsible spacer or bearings
may result.

REMOVAL AND INSTALLATION (Continued)
(14) Tighten the pinion nut until there is zero
bearing end-play (Fig. 30).
(15) Tighten the nut to 271 N·m (200 ft. lbs.).
CAUTION: Never loosen pinion nut to decrease pin-
ion bearing rotating torque and never exceed spec-
ified preload torque. If preload torque or rotating
torque is exceeded a new collapsible spacer must
be installed. The torque sequence will then have to
be repeated.
(16) Using Holder 6719 and a torque wrench set at
474 N·m (350 ft. lbs.), crush collapsible spacer until
bearing end play is taken up.
NOTE: If the spacer requires more than 474 N·m
(350 ft. lbs.) torque to crush, the collapsible spacer
is defective and must be replaced.
(17) Slowly tighten the nut in 6.8 N·m (5 ft. lbs.)
increments until the desired rotating torque is
achieved. Measure the rotating torque frequently to
avoid overcrushing the collapsible spacer (Fig. 31).
(18) Check bearing rotating torque with an inch
pound torque wrench (Fig. 31). The torque necessary
to rotate the pinion should be:
• Original Bearings — 1 to 2.5 N·m (10 to 20 in.
lbs.).
• New Bearings — 1.7 to 2.5 N·m (15 to 22 in.
lbs.).
(19) Install the differential in the axle housing.
