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.

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:

(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.

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

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

(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

_ 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.

FRONT DISC BRAKE PAD CHECK AND REPLACE-
MENiNWFOAF
NOTE
The brake pads have wear indicators that contact the brake discd’when the brake pad thickness becomes 2 mm
(.08 in.), and
emit a squealing sound to warn the driver.
1. Check brake pad thickness through caliper body check
port.Limit: 2.0 mm
(.08 in.)
Caution1. When the limit is exceeded, replace the pads at
both sides, and also the brake pads for the wheelson the opposite side at the same time.
2.If there is a significant difference in the thicknesses
of the pads on the left and right sides, check the
sliding condition of the piston, lock pin sleeve and
guide pin sleeve.
2.Remove lock or guide pin. Lift caliper assembly and retain
with wires.
Caution
Do not wipe off the special grease that is on the guide
-pin or allow it to contaminate the guide pin.
