Dodge Durango (HB). Manual — part 35
INSTALLATION
NOTE: The ring gear and pinion are serviced in a
matched set. Never replace one gear without
replacing the other. If ring and pinion gears or
bearings are replaced, Refer to Adjustments for
Pinion Gear Depth Setting.
1. Apply Mopar Door Ease or equivalent lubricant to
outside surface of the bearing cups.
2. Install rear pinion bearing cup with Installer D-145
(1) and Handle C-4171 (2).
3. Install front pinion bearing cup with Installer D-129
(1) and Handle C-4171 (2).
4. Install
pinion
front
bearing
and
oil
slinger
if
equipped.
5. Apply a light coating of gear lubricant on the lip of
pinion seal.

pinion.
10. Install pinion gear into housing.
11. Install companion flange with Installer C-3718.
12. Install new pinion nut and tighten to 271 N·m (200
ft. lbs.).
13. With holder (2) and a torque wrench (3) set at
474 N·m (350 ft. lbs.), tighten pinion nut until end
play is taken up.

14. Slowly tighten the pinion flange (1) nut in 6.8 N·m
(5 ft. lbs.) increments until rotating torque is
achieved. Measure rotating torque frequently to
avoid overcrushing the collapsible spacer. The
pinion rotating torque 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.)
NOTE: Never loosen pinion nut to decrease pinion
bearing rotating torque and never exceed speci-
fied preload torque.
15. Invert differential case and start two ring gear
bolts. This will provide case-to-ring gear bolt hole
alignment.
16. Invert differential case in the vise.
17. Install new ring gear bolts (2) and alternately
tighten to 108 N·m (80 ft. lbs.).
CAUTION: Never reuse the ring gear bolts. Failure
to follow these instructions will damage bolts.
18. Install differential in axle housing and verify gear
mesh and contact pattern.
19. Install differential cover.
