SERVICE POINTS OF REMOVALN031BAL1. REMOVAL OF DRIVE SHAFT
With a tyre lever, etc.,remove the drive shaft from the
differential carrier.
NOTEBe cautious to ensure that the differential carrier oil seal is
not damaged by the drive shaft spline.
3. DISCONNECTION OF PROPELLER SHAFT
(1) Place mating marks on the differential companion
flange and flange yoke for reference during reassembly.(2) Remove the differential carrier and propeller shaft
connection.(3) Support the propeller shaft with wire.

PLACEMENT
NOBIYAAUse the special tool to pull out and press in the differential
support member bushing.
NOTEPress in the bushing from the beveled part of the differential
support member; press in until the end surface of the bushing
outer cylinder is flush with the support member.
SERVICE POINTS OF INSTALLATIONN03lDAK3. CONNECTION OF PROPELLER SHAFT
Align the mating marks on the flange yoke and the
companion flange to install the propeller shaft.
INSPECTION BEFORE DISASSEMBLYNOJIEAIHold the working base in a vice, and attach the differential
carrier to the working base.
FINAL DRIVE GEAR BACKLASH
With the drive pinion locked in place, measure the final drive
gear backlash with a dial indicator on the drive gear.

llG0076DRIVE GEAR RUNOUT
Measure the drive gear
runout at the shoulder on the reverse
side of the drive gear.
Limit: 0.05 mm
(.002 in.)
DIFFERENTIAL GEAR BACKLASH
While locking the side gear with the wedge, measure the
differential gear backlash with a dial indicator on the pinion
gear.Standard value:O-0.076 mm (O-.003 in.)
’ Limit:0.2 mm (.008 in.)
FINAL DRIVE GEAR TOOTH CONTACT
Check the final drive gear tooth contact by following the steps
below.
(1) Apply a thin, uniform coat of machine blue to both surfaces
of the drive gear teeth.
(2) Insert a brass rod between the differential carrier and the
differential case, and then rotate the companion flange by
hand (once in the normal direction, and then
on& in the
reverse direction) while applying a load to the drive gear, sothat the revolution torque [approximately
2.5-3.0 Nm
(28-33
in.lbs.)] is applied to the drive pinion.
CautionIf the drive gear is rotated too much, the tooth contact
pattern will become unclear and difficult to check.
(3) Check the tooth contact condition of the drive gear and
drive pinion.

kPrize out the differential case assembly using hammer
‘-
shafts.
NOTEWhen removing the differential case assembly, the
re’mov-
al should be accomplished slowly and carefully and cautionpaid to ensure that the side bearing outer race is not
dropped.
Keep the right and left side bearings separate, so that theydo not become mixed at the time of reassembly.
7. REMOVAL OF SIDE BEARING INNER RACES
Pull out the side bearing inner races by using the special
tools.8. REMOVAL OF DRIVE GEAR
(1) Make the mating marks to the differential case and the
drive gear.
(2) Loosen the drive gear attaching bolts in diagonal
fisequence to remove the drive gear.
9. REMOVAL OF LOCK PIN
Drive out the lock pin with a punch and remove the pinion
gears, pinion washers, side gears and side gear spacers.
17. REMOVAL OF SELF-LOCKING NUT
Use the special tools to hold the companion flange and
remove the companion flange self-locking nut.

Y223(5) Remove the companion flange and drive pinion once
again.Drive the oil seal into the gear carrier front lip by using
the special tool.
Apply multipurpose grease to the oil seal lip.
Specified grease: MOPAR Multi-Mileage Lubricant
Part No.2525035 or equivalent
(6) Apply a thin coat of multipurpose grease to the
companion flange contacting surface of the washer
before installing drive pinion assembly.
Specified grease: MOPAR Multi-Mileage Lubricant
Part No.2525035 or equivalent
(7) Install the drive pinion assembly and companion flange
with mating marks properly aligned, and tighten the
companion flange self-locking nut to the specified
torque by using the special tools.
(8)Measure the drive pinion turning torque (with oil seal) toverify that the drive pinion turning torque complies with
the standard value.
Standard value:
Rotation torque
(starting friction torque)Nm
(in.lbs.)
IIIIIf there is a deviation from the standard value, check
whether or not there is incorrect tightening torque of
the companion flange tightening self-lock nut, or incor-
rect fitting of the oil seal.
. ADJUSTMENT OF DIFFERENTIAL GEAR BACKLASH
Adjust the differential gear backlash by the following
procedures:(1) Assemble the side gears, side gear spacers, pinion
gears, and pinion washers into the differential case.
(2) Temporarily install the pinion shaft.
NOTEDo not drive in the lock pin yet.

11 S564(3) Adjust the differential gear backlash by the following
procedures:
@ While locking the side gear with the wedge,
measure the differential gear backlash with a dial
indicator on the pinion gear.
NOTEThe measurement should be made for both pinion
gears individually.
Standard value:
O-0.076 mm (O-.003 in.)
Limit:0.2 mm
(.008 in.)
@ If the differential gear backlash exceeds the limit,
adjust the backlash by installing thicker side gear
spacers.
@ Measure the differential gear backlash once again,
and confirm that it is within the limit.
NOTE(1) After adjustment, check that the backlash is the
less than the limit and differential gear rotates
smoothly.
(2) When adjustment is impossible, replace the side
gear and the pinion gear as a set.
23. INSTALLATION OF LOCK PIN
(1) Align the pinion shaft lock pin hole with the differential
case lock pin hole, and drive in the lock pin.
(2) Stake the lock pin with a punch at two points.
w24. INSTALLATION OF DRIVE GEAR
(1) Clean the drive gear attaching bolts.
(2) Use an
Ml0 X 1.25 tap to remove the adhesive
adhering to the threaded holes of the drive gear, and
then clean the threaded holes by applying compressed
air.(3) Apply multipurpose adhesive to the threaded holes of
the drive gear.
Specified adhesive:MOPAR
Part No.4318031 or
4318032 or equivalent
(4) Install the drive gear onto the differential case with the
Amating marks properly aligned. Tighten the bolts to the
specified torque in a diagonal sequence.

(5) Tap the side bearing spacers with a brass bar to fit themto the side bearing outer race.
4(6) Align the mating marks on the gear carrier and the
bearing cap, and then tighten the bearing cap.
(7) With the drive pinion locked in place, measure the final
drive gear backlash with a dial indicator on the drive
gear.
NOTE
-cc
Measure at four points or more on the circumference ofthe drive gear.
Standard value:
0.11-0.16 mm (.004-.006 in.)
(8) Change the side bearing spacers as illustrated, and thenadjust the final drive gear backlash between the drive
gear and the drive pinion.
NOTEWhen increasing the number of side bearing spacers,
use the same number for each, and as few as possible.(9) Check the drive gear and drive pinion for tooth contact.
If poor contact is evident, make adjustment. (Refer to
P.3-22.)(lO)Measure the drive gear
runout at the shoulder on the
reverse side of the drive gear.
Limit: 0.05 mm
(.002 in.)
(ll)lf the drive gear runout exceeds the limit, reinstall by
changing the phase of the drive gear and differential
,+case, and remeasure.

_ CAUTION
When servicing brake assemblies or components, do not create dust by sanding, grinding or by cleaning
brake parts with a dry brush or with compressed air. A WATER DAMPENED CLOTH SHOULD BE USED.
Many brake components contain asbestos fibers which can become air-borne if dust is created duringservice operations. Breathing dust which contains asbestos fibers can cause serious bodily harm.
