SERVICE POINTS OF REASSEMBLYNOJUBD2. PRESS FITTING OF OIL SEAL
(1) With the special tool, press fit the oil seal until it is flushwith the end of the gear carrier.
(2) Apply multipurpose grease to the oil seal lip.
Specified grease: MOPAR Multi-Mileage Lubricant
Part No.2525035 or equivalent
3. lNSTALLATlON OF DRIVE PINION REAR BEARING
OUTER RACE/4. DRIVE PINION FRONT BEARING
OUTER RACE
Press-fit the drive pinion rear and front bearing outer racesinto the gear carrier by using the special tools.
CautionBe careful not to press in the outer race at an angle.
l ADJUSTMENT OF PINION HEIGHT
Adjust the drive pinion height by the following procedures:
(1) Install special tools and drive pinion front and rear
bearing inner races on the gear carrier in the sequenceshown in the illustration.
NOTEApply a thin coat of multipurpose grease to the mating
face of the washer of the special tool.
Specified grease: MOPAR Multi-Mileage Lubricant
Part No.2525035 or equivalent
(2) Tighten the handle of the special tool until the standardvalue of drive pinion turning torque is obtained.
(3) Measure the drive pinion turning torque (without the oil
seal).Standard value:
Rotation torque
(starting friction torque)Nm
(in.lbs.)
I
NoneNew(with rust-I0.9-1.2 (8-10)prevention oil)New/reused Oil application
NOTE
0.4-0.5 (3-4)(I) Gradually tighten the nut of the special tool while
checking the drive pinion turning torque.
(2) Because the special tool cannot be turned one turn, turnit several times within the range that it can be turned;then, after fitting to the bearing, measure the rotation
torque.

MB990031(4) Position the special tool in the side bearing seat of the
gear carrier, and then select a drive pinion rear shim of athickness which corresponds to the gap between the
special tools.
NOTE
Clean the side bearing seat thoroughly. When position-
ing the special tool, be sure that the cut-out sections ofthe special tool are in the position shown in the
illustration, and also confirm that the special tool is in
close contact with the side bearing seat.
When selecting the drive pinion rear shims, keep the
number of shims to a minimum.
(5) Fit the selected drive pinion rear shim(s) to the drive
pinion, and press-fit the drive pinion rear bearing inner
race by using the special tool.
. ADJUSTMENT OF DRIVE PINION PRELOAD
Adjust the drive pinion turning torque by using the following
procedures:
(1) Fit the drive pinion front shim(s) between the drive
pinion spacer and the drive pinion front bearing inner
race.
(2) Tighten the companion flange to the specified torque byusing the special tools.
NOTEDo not install the oil seal.
(3) Measure the drive pinion turning torque (without the oil
seal) by using the special tools.
Standard value:

0.4-0.5 (3-4)
(4) If the drive pinion turning torque is not within the range
of the standard value, adjust the turning torque by
replacing the drive pinion front shim(s) or the drive
pinion spacer.
NOTEWhen selecting the drive pinion front shims, if the
number of shims is large, reduce the number of shims
to a minimum by selecting the drive pinion spacers.

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.

INSPECTION BEFORE DISASSEMBLYNO3IEBA1. CHECKING THE DIFFERENTIAL GEAR BACKLASH
(1) Secure the differential case assembly in a vise so that
the differential side gear (right) is facing upward.
Caution
When securing the vise, be sure not to hold the
differential case assembly too tightly.
(2) Insert a 0.03 mm (.0012 in.) feeler gauge at two places
(diagonally) between differential case
B and the thrust
washer (right).
CautionDo not insert a feeler gauge in the oil groove of
differential case B.

B.3. SELECTION OF THE THRUST WASHER (LEFT)
(1) If the differential side gear and pinion mate gear have
been replaced, select the thrust washer (left) by
following the steps below.
@ Wash the differential side gear and pinion mate gear
in unleaded gasoline to remove all oil, grease, etc.
@ Install the previously used thrust washers (being
careful the left and right ones are used at the
correct side), together with the gears, viscous unit,
pinion mate washer and pinion shaft, to differential
cases A and
B, and then, using screws, secure
them temporarily.
@ Secure the differential case assembly in a vise so
that the differential side gear (right) is facing
upward.Caution
When securing in the vise, be sure not to hold the
differential case assembly too tightly.
@I Insert a 0.03 mm LOO12 in.) feeler gauge at two
places (diagonally) between differential case
B and
the thrust washer (right).
CautionDo not insert a feeler gauge in the oil groove of
rsrdifferential case B.
