(4) Install yoke with Installer C–3718 and holder
6958 (Fig. 19).
(5) If the original pinion bearings are being used,
install differential assembly and axle shafts, if neces-
sary.
NOTE: If new pinion bearings were installed, do not
install the differential assembly and axle shafts until
after the pinion bearing preload and rotating torque
are set.
(6) Install the yoke washer and a new nut on the
pinion gear. Tighten the nut to 298 N·m (220 ft. lbs.)
minimum. Do not over–tighten. Maximum torque
is 380 N·m (280 ft. lbs.).
CAUTION: Never
loosen
pinion
gear
nut
to
decrease pinion 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 have to be
repeated.
NOTE: A new collapsible spacer will start to crush
at around 265 ft. lbs. torque. If the spacer requires
more than 280 ft. lbs. torque to crush, the collaps-
ible spacer is defective.
(7) Using yoke holder 6958, a short length of 1 in.
pipe, and a torque wrench set at 380 N·m (280 ft.
lbs.), crush collapsible spacer until bearing end play
is taken up (Fig. 20).
(8) Slowly tighten the nut in 6.8 N·m (5 ft. lbs.)
increments until the rotating torque is achieved.
