(11) Lower the vehicle.
COLLAPSIBLE SPACER
REMOVAL W/PINION INSTALLED
(1) Raise and support the vehicle.
(2) Remove wheel and tire assemblies.
(3) Remove rear brake drums. Refer to Group 5,
Brakes, for proper procedures.
(4) Mark the propeller shaft and pinion yoke for
installation reference.
(5) Remove the propeller shaft from the yoke.
(6) Rotate the pinion gear three or four times.
(7) Measure the amount of torque necessary to
rotate the pinion gear with a (in. lbs.) dial-type
torque wrench. Record the torque reading for instal-
lation reference.
(8) Using Holder 6958 to hold the pinion yoke,
remove the pinion nut and washer.
(9) Use Remover C-452 and Wrench C-3281 to
remove the pinion yoke (Fig. 12).
(10) Use a suitable pry tool or a slide hammer
mounted screw to remove the pinion shaft seal.
(11) Remove the front pinion bearing using a pair of
suitable pick tools to pull the bearing straight off the
pinion gear shaft. It may be necessary to lightly tap the
end of the pinion gear with a rawhide or rubber mallet
if the bearing becomes bound on the pinion shaft.
(12) Remove the collapsible spacer.
REMOVAL W/PINION REMOVED
(1) Raise and support the vehicle.
(2) Remove wheel and tire assemblies.

Brakes, for proper procedures.
(4) Mark the propeller shaft and pinion yoke for
installation reference.
(5) Remove the propeller shaft from the yoke.
(6) Rotate the pinion gear three or four times.
(7) Measure the amount of torque necessary to
rotate the pinion gear with a (in. lbs.) dial-type
torque wrench. Record the torque reading for instal-
lation reference.
(8) Remove differential assembly from axle hous-
ing.
(9) Using Holder 6958 to hold yoke, remove the
pinion yoke nut and washer.
(10) Using Remover C–452 and Wrench C–3281,
remove the pinion yoke from pinion shaft (Fig. 12).
(11) Remove the pinion gear from housing (Fig.
13). Catch the pinion with your hand to prevent it
from falling and being damaged.
(12) Remove collapsible spacer from pinion shaft.
INSTALLATION
(1) Install a new collapsible preload spacer on pin-
ion shaft (Fig. 14).
(2) If pinion gear was removed, install pinion gear
in housing.
(3) Install pinion front bearing, if necessary.
(4) Apply a light coating of gear lubricant on the
lip of pinion seal. Install seal with Installer C-3972-A
and Handle C–4171 (Fig. 15).
(5) Install yoke with Screw 8112, Cup 8109, and
Holder 6958 (Fig. 16).
(6) If the original pinion bearings are being used,
install differential assembly and axle shafts, if neces-
sary.

REMOVAL AND INSTALLATION (Continued)
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.
(7) Install the yoke washer and a new nut on the
pinion gear. Tighten the pinion nut until there is zero
bearing end-play.
(8) Tighten the nut to 271 N·m (200 ft. lbs.).
CAUTION: Never
loosen
pinion
gear
nut
to
decrease pinion gear bearing rotating torque and
never exceed specified preload torque. If preload
torque or rotating torque is exceeded a new col-
lapsible spacer must be installed. The torque
sequence will then have to be repeated.
(9) Using yoke holder 6958 and a torque wrench
set at 474 N·m (350 ft. lbs.), crush collapsible spacer
until bearing end play is taken up (Fig. 17).
NOTE: If more than 474 N·m (350 ft. lbs.) of torque
is necessary to remove the bearing end play, the
collapsible
spacer
is
defective
and
must
be
replaced.

REMOVAL AND INSTALLATION (Continued)
(10) Slowly tighten the nut in 6.8 N·m (5 ft. lbs.)
increments until the rotating torque is achieved.
Measure the rotating torque frequently to avoid over
crushing the collapsible spacer (Fig. 18).
(11) Check rotating torque with a (in. lbs.) torque
wrench (Fig. 18). The torque necessary to rotate the
pinion gear should be:
• Original Bearings — The reading recorded dur-
ing removal, plus an additional 0.56 N·m (5 in. lbs.).
• New Bearings — 1.5 to 4 N·m (15 to 35 in. lbs.).
(12) Install differential assembly and axle shafts,
if necessary.
(13) Align marks made previously on yoke and
propeller shaft and install propeller shaft.
(14) Install rear brake drums. Refer to Group 5,
Brakes, for proper procedures.
(15) Add gear lubricant, if necessary. Refer to
Lubricant Specifications of this section for lubricant
requirements.
(16) Install wheel and tire assemblies.
(17) Lower vehicle.
AXLE SHAFT
REMOVAL
(1) Raise and support vehicle. Ensure that the
transmission is in neutral.
(2) Remove wheel and tire assembly.
(3) Remove brake drum. Refer to Group 5, Brakes,
for proper procedure.
(4) Clean all foreign material from housing cover
area.
(5) Loosen housing cover bolts. Drain lubricant
from the housing and axle shaft tubes. Remove hous-
ing cover.
(6) Rotate differential case so that pinion mate
gear shaft lock screw is accessible. Remove lock
screw and pinion mate gear shaft from differential
case (Fig. 19).
(7) Push axle shaft inward and remove axle shaft
C–clip lock from the axle shaft (Fig. 20).
(8) Remove axle shaft. Use care to prevent damage
to axle shaft bearing and seal, which will remain in
axle shaft tube. Also, exercise care not to damage the

(10) Inspect roller bearing contact surface on axle
shaft for signs of brinelling, galling and pitting. If
any of these conditions exist, the axle shaft and/or
bearing and seal must be replaced.
INSTALLATION
(1) Lubricate bearing bore and seal lip with gear
lubricant. Insert axle shaft through seal, bearing,
and engage it into side gear splines.

case and install lock screw with Loctite
t on the
threads. Tighten lock screw to 19 N·m (14 ft. lbs.)
torque.
(5) Install cover and add fluid. Refer to Lubricant
Change procedure in this section for procedure and
lubricant requirements.
(6) Install brake drum. Refer to Group 5, Brakes,
for proper procedures.
(7) Install wheel and tire.
(8) Lower vehicle.
AXLE SHAFT SEAL AND BEARING
REMOVAL

(2) Remove the axle shaft seal from the end of the
axle shaft tube with a small pry bar.
NOTE: The seal and bearing can be removed at the
same time with the bearing removal tool.
(3) Remove the axle shaft bearing from the axle
tube with Bearing Removal Tool Set 6310 using
Adapter Foot 6310-5 (Fig. 21).
(4) Inspect the axle shaft tube bore for roughness
and burrs. Remove as necessary.
INSTALLATION
Do not install the original axle shaft seal.
Always install a new seal.
(1) Wipe the axle shaft tube bore clean.
(2) Install axle shaft bearing with Installer 6436
and Handle C–4171. Ensure that the part number on
the bearing is against the installer.
(3) Install the new axle shaft seal with Installer
6437 and Handle C–4171 (Fig. 22).
