Dodge Durango (HB). Manual — part 42
7. Install bolts into two of the threaded holes in the
flange 180° apart.
8. Position Holder 6719 against the flange and install
a bolt and washer into one of the remaining
threaded holes. Tighten the bolts so the Holder
6719 is held to the flange.
9. Remove pinion nut and washer.
10. Remove flange (1) with Remover C-452 (2).
11. Remove pinion seal with a pry tool or slide-ham-
mer mounted screw.
INSTALLATION
1. Apply a light coating of gear lubricant on the lip of
pinion seal.
2. Install new pinion seal with Installer C-4076-B (3)
and Handle C-4735 (1).

3. Install flange on the end of the shaft with the refer-
ence marks aligned.
4. Install bolts into two of the threaded holes in the
flange 180° apart.
5. Position Holder 6719 against flange. Install a bolt
and washer into one of the remaining threaded
holes. Tighten bolts so Holder 6719 is held to the
flange.
6. Install flange on pinion shaft with Installer C-3718
and Holder 6719.
7. Install pinion washer and a new pinion nut. The
convex side of the washer must face outward.
CAUTION: Do not exceed the minimum tightening
torque
when
installing
the
companion
flange
retaining nut at this point. Failure to follow these
instructions can damage the collapsible spacer or
bearings.
8. Hold flange with Holder 6719 (2) and tighten pinion
nut to 285 N·m (210 ft. lbs.). Rotate pinion several
revolutions to ensure bearing rollers are seated.
9. Rotate pinion flange (1) 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 can
damage the collapsible spacer or bearings.
10. If rotating torque is low use Holder 6719, to hold
flange and tighten pinion nut in 6.8 N·m (5 ft. lbs.)
increments
until
proper
rotating
torque
is
achieved.
NOTE: The seal replacement is unacceptable if
final pinion nut torque is less than 285 N·m (210 ft.
lbs.).
NOTE: The bearing rotating torque should be con-
stant during a complete revolution of the pinion. If the rotating torque varies, this indicates a binding con-
dition.
11. Install propeller shaft.
12. Install rear brake rotors components.
