(6) Position the pinion yoke on the end of the shaft
with the reference marks aligned.
(7) Seat yoke on pinion shaft with Installer C-3718
and Wrench 6719.
(8) Remove the tools and install the pinion yoke
washer. The convex side of the washer must face out-
ward.
CAUTION: Do not exceed the minimum tightening
torque when installing the pinion yoke retaining nut
at this point. Damage to collapsible spacer or bear-
ings may result.
(9) Hold pinion yoke with Yoke Holder 6719 and
tighten shaft nut to 285 N·m (210 ft. lbs.) (Fig. 15).
Rotate the pinion several revolutions to ensure the
bearing rollers are seated.
(10) Rotate the pinion using an (in. lbs.) 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. 16).
CAUTION: Never loosen pinion nut to decrease pin-
ion gear bearing rotating torque and never exceed
specified
preload
torque.
If
preload
torque
is
exceeded
a
new
collapsible
spacer
must
be
installed. The torque sequence will then have to be
repeated.
(11) If the rotating torque is low, use Yoke Holder
6719 to hold the pinion yoke (Fig. 15) 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, this indicates a binding
condition.
(12) The seal replacement is unacceptable if the
final pinion nut torque is less than 285 N·m (210 ft.
lbs.).
(13) Install the propeller shaft with the installa-
tion reference marks aligned.
(14) Tighten the universal joint yoke clamp screws
to 19 N·m (14 ft. lbs.).
(15) Install the brake drums.
(16) Install wheel and tire assemblies and lower
the vehicle.
(17) Check the differential housing lubricant level.
DIFFERENTIAL
REMOVAL
(1) Remove the axle shafts.
NOTE: Side play resulting from bearing races being
loose on case hubs requires replacement of the dif-
ferential case.
