INSPECT
1.
Check the gears for wear or damage. Inspect the
spider gears and axle gears for worn teeth. In-
spect the cross for wear where the gears turn.
The cross and the holes for the cross in the dif-
ferential case must fit tightly.
2.
Inspect the bearings and bearing surfaces for
damage.
3.
The mounts must turn freely on the axle hous-
ing. The splines for the axle shafts must not be
damaged.
ASSEMBLE
WARNING
Hot parts. Wear protective clothing and gloves
to prevent burns.
1.
If the drive gear was removed from the differen-
tial case, put the drive gear in hot water that is
82 to 105 C (180 to 220
F)
for approximately 10
minutes. Remove the drive gear from the water
and put it on the differential case. Do not use
a press or a hammer to install the drive gear.
Install the twelve capscrews and special hard-
ened washers. Tighten the capscrews to 111 N•m
(82 lbf ft). Make sure the drive gear is in the cor-
rect position against the flange of the differential
case.
2.
Lubricate and install a side gear and thrust
washer in the differential case as shown in Fig-
ure 10. Make sure the side of the thrust washer
with dents is toward the side gear.
3.
Install the spider (cross), differential pinions,
and thrust washers into the differential case as
shown in Figure 11.
4.
Install the second side gear and thrust washer
over the spider and differential pinions as shown
in Figure 12.
Put the second half of the dif-
ferential case over the first half and the gears
as shown in Figure 12. Make sure the marks
are aligned. Install four of the capscrews in a
cross pattern. Tighten the capscrews to 50 N•m
(37 lbf ft). Install the remaining capscrews and
tighten them in a cross pattern.
5.
Install the bearing cones on the differential case.
6.
Apply axle lubricant on the inner diameter of the
bearing cups and on both bearing cones that are
installed on the differential. Do not permit lubri-
cant on the outer diameter of the bearing cups or
the bearing bores of the housing.
