DRIVE GEAR BACKLASH
ACX01034AB
1. With the drive pinion locked in place, use a dial
gauge to measure the drive gear backlash in four
or more places on the drive gear.
Standard value: 0.11
− 0.16 mm
2. If the backlash is not within the standard value,
adjust the final drive gear backlash (Refer to ).
3. After the adjustment, inspect the final drive gear
tooth contact.
DRIVE GEAR RUNOUT
ACX01036 AB
1. Measure the drive gear runout at the shoulder on
the reverse side of the drive gear.
Limit: 0.05 mm
2. When the runout exceeds the limit value, check
for foreign material between drive gear rear side
and differential case, and for loose drive gear
installation bolts.
3. When check (2) gives normal results, reposition
drive gear and differential case and remeasure.
4. If adjustment is impossible, replace differential
case, or replace drive gear and pinion as a set.
DIFFERENTIAL GEAR BACKLASH
AC102885
Wedge
Side gear
spacer
AC
Side gear
spacer
1. Insert a wedge between the side gear and the
pinion shaft to lock the side gear.
2. While locking the side gear with the wedge,
measure the differential gear backlash with a dial
indicator on the pinion gear.
Use the measurement procedure for the other
pinion gear.
Standard value: 0.01
− 0.250 mm
3. If the backlash exceeds the standard value, adjust
it by replacing the side gear spacers.
4. If adjustment is not possible, replace the side
gears and pinion gears as a set.
DRIVE GEAR TOOTH CONTACT
Check the tooth contact of drive gear by following the
steps below.
ACX01037 AB
1. Apply a thin, uniform coat of machine blue to both
surfaces of the drive gear teeth.

CAUTION
If the drive gear is rotated too much, the tooth
contact pattern will become unclear and difficult
to check.

2. Insert special tool remover bar (MB990939)
between the differential carrier and the differential
case, and then rotate the companion flange by
hand (once in the normal direction, and then once
in the reverse direction) while applying a load to
the drive gear so that the revolution torque
(approximately 2.5
− 3.0 N⋅m) is applied to the
drive pinion.
3. Check the tooth contact condition of the drive gear
and drive pinion.

Problem
Solution
1. Narrow tooth side
2. Drive-side tooth surface
(the side applying power during forward
movement)
3. Wide tooth side
4. Coast-side tooth surface
(the side applying power during reverse
movement)

position the drive gear

Decrease the thickness of
the drive pinion rear shim,
and position the drive pinion
farther from the centre of
the drive gear. Also, for
backlash adjustment,
position the drive gear
closer to the drive pinion.
NOTE: Check the tooth contact pattern to confirm
that the adjustments of the pinion height and
backlash have been done properly. Continue to
adjust the pinion height and backlash until the
tooth contact pattern resembles the standard pat-
tern. If, even after adjustments have been made,
the correct tooth contact pattern cannot be
obtained, it means that the drive gear and the
drive pinion have become worn beyond the allow-
able limit. Replace the gear set.
