Чтобы не было пальцем в небо - тогда полностью разбираем задний мост с редуктором и делаем по науке

PINION SEAL

REMOVAL
(1) Raise and support the vehicle.
(2) Mark the universal joint, pinion yoke and pin-
ion shaft for installation reference.
(3) Remove propeller shaft from pinion yoke.
(4) Remove the wheel and tire assemblies.
(5) Remove the brake drums.
(6) Rotate the pinion yoke three or four times.
(7) Measure rotating torque of the pinion gear
with an inch pound torque wrench and record the
eading for installation reference.
(8) Hold the pinion yoke with Holder 6719 and
emove the pinion nut and washer.
(9) Remove yoke with Remover C-452 (Fig. 24).
(10) Remove pinion seal with a pry tool or screw
mounted to a slide-hammer mounted.

INSTALLATION

(1) Apply a light coating of gear lubricant on the
lip of pinion seal.
NOTE: The outer perimeter of the seal is pre-coated
with a special sealant. An additional application of
sealant is not required.
(2) Install the new pinion seal (Fig. 25) with
Installer C-4076-A and Handle C-4735.
(3) Install pinion yoke on the shaft with the refer-
ence marks aligned.
(4) Seat yoke on pinion shaft with Installer C-3718
and Holder 6719A.
(5) Remove the tools and install the pinion yoke
washer. The convex side of the washer must face out-
ward.
(6) Using yoke Holder 6719A tighten shaft nut to
285 N·m (210 ft. lbs.) (Fig. 26). Rotate the pinion sev-
eral revolutions to ensure the bearing rollers are
seated.
(7) Rotate the pinion using an inch pound torque
wrench. Rotating torque should be equal to the read-
ing recorded during removal, plus an additional 0.56
N·m (5 in. lbs.) (Fig. 27).
CAUTION: Never loosen pinion nut to decrease pin-
ion rotating torque and never exceed specified pre-
load torque. If preload torque is exceeded a new
collapsible spacer must be installed.
(8) If the rotating torque is low, use Holder 6719A
(Fig. 26) and tighten the pinion nut in 6.8 N·m (5 ft.
lbs.) increments until proper rotating torque is
achieved.
NOTE: The bearing rotating torque should be con-
stant during a complete revolution of the pinion. If
the rotating torque varies, it indicates a binding
condition.
(9) The seal replacement is unacceptable if the
final pinion nut torque is less than 285 N·m (210 ft.
lbs.).
(10) Install the propeller shaft with the installa-
tion reference marks aligned.
(11) Install the brake drums.
(12) Check the differential housing lubricant level.
(13) Install wheel and tire assemblies and lower
the vehicle.
