Dodge Durango (HB). Manual — part 52
7. Hold companion flange with Holder 6719 (2) and
tighten pinion nut with a torque set to 285 N·m
(210 ft. lbs.). Rotate pinion several revolutions to
ensure the bearing rollers are seated.
8. Rotate pinion with an inch pound torque wrench
(2). Rotating torque should be equal to the reading
recorded during removal plus an additional 0.56
N·m (5 in. lbs.).
CAUTION: Never loosen pinion nut to decrease pinion bearing rotating torque and never exceed specified
preload torque. If rotating torque is exceeded, a new collapsible spacer must be installed. Failure to follow
these instructions will result in damage to the collapsible spacer
9. If rotating torque is low, use Holder 6719 to hold the companion flange and tighten pinion nut in 6.8 N·m (5 ft.
lbs.) increments until proper rotating torque is achieved.
NOTE: The bearing rotating torque should be constant during a complete revolution of the pinion. If the
rotating torque varies, this indicates a binding condition.
NOTE: The seal replacement is unacceptable if the final pinion nut torque is less than 285 N·m (210 ft. lbs.).
10. Install propeller shaft..

ASSEMBLY
NOTE: If same gears and thrust washers are being
used, install them into their original locations.
1. Lubricate all differential components with axle lubri-
cant.
2. Install
differential
side
gears
(2)
and
thrust
washers.
3. Install first pinion gear (3) with thrust washer into
differential window (1) and side gears (2). Rotate
pinion gear into the case.
4. Install remaining pinion gear and thrust washer.
Rotate gears to align hole in the pinion gears with
hole in the differential case.
5. Slide pinion shaft into the case and through the
pinion gears to align the gears.
INSTALLATION
1. Apply a coat of hypoid gear lubricant to differential bearings, bearing cups and threaded adjusters.
NOTE: Grease can be used to keep the adjusters in position.
2. Install differential assembly into the housing.
3. Install differential bearing caps in their original locations.
4. Install bearing cap bolts and tighten the upper bolts to 14 N·m (10 ft. lbs.). Tighten lower bolts finger-tight until
the bolt head is seated.
5. Perform differential bearing preload and adjustment procedure.
