Synchronizer
Check items below. If necessary, replace them with new ones.
lDamage and unusual wear on contact surfaces of coupling
sleeve, synchronizer hub, and insert spring.
lCoupling sleeve and synchronizer hub must move smoothly.
lIf any crack, damage, or excessive wear is found on cam face of
baulk ring or working face of insert, replace it.
Baulk ring clearance
lPress baulk ring against cone, and measure clearance between
baulk ring and cone. If measurement is below limit, replace it
with a new one.
Bearing
Check items below. If necessary, replace them with new ones.
lDamage and rough rotation of bearing.
ASSEMBLY
Paying attention to following work, assemble in reverse order of disassembly.
CAUTION:
lBe careful with orientation of insert spring.

Assembly and Disassembly (RS5F51A)ECS004UR
PRE-INSPECTION
lCheck the clearance between side gear and differential case as
follows.
1. Clean final drive assembly sufficiently to prevent side gear thrust
washer, differential case, side gear, and other parts from sticking
by gear oil.
2. Upright the differential case so that the side gear to be measured faces upward.
3. Place final drive adapter and dial gauge onto side gear. Move
side gear up and down, and measure the clearance.
4. If not within specification, adjust the clearance by changing
thrust washer thickness.
5. Turn differential case upside down, and measure the clearance
between side gear and differential case on the other side in the
same way.
DISASSEMBLY
1. Remove mounting bolts.Then, separate the final gear from differential case.
2. Using a drift and puller, remove differential side bearing (clutch
housing side).
3. Using a drift and puller, remove differential side bearing (tran-
saxle case side).

4. Using a pin punch, pull out lock pin and pinion mate shaft.
5. Rotate pinion mate gears, and remove pinion mate gears, pinion
mate thrust washers, side gears, and side gear thrust washers
from differential case.
INSPECTION AFTER DISASSEMBLY
Gear, Washer, Shaft and Case
lCheck side gears, side gear thrust washers, pinion mate shaft,
pinion mate gears, pinion mate thrust washers and differential
case. If necessary, replace with a new one.
Bearing
lCheck for bearing damage and rough rotation. If necessary,
replace with a new one.
CAUTION:
When replacing tapered roller bearing, replace outer and inner
races as a set.
ASSEMBLY
1. Apply gear oil to sliding area of differential case, each gear, and thrust washer.
2. Install side gear thrust washers and side gears into differential
case.
3. While rotating pinion mate thrust washers and pinion mate
gears, aligning them diagonally, install them into differential
case.

4. Insert pinion mate shaft into differential case.
CAUTION:
Be sure not to damage pinion mate thrust washers.
5. Measure end play of side gears following procedure below.
Then select side gear thrust washer.
a. Upright the differential case so that its side gear to be measured
face upward.
b. Place final drive adapter and dial gauge onto side gears.
c. Move side gears up and down to measure end play, and select
thrust washer so that it satisfies standard.
CAUTION:
Place differential case upside down. Be sure to measure
end play for opposite side-gears likewise.
Thrust washer
CAUTION:
Only one thrust washer can be selected.
6. Using a pin punch (special service tool), drive a lock pin into the
pinion mate shaft.
CAUTION:
Do not reuse the lock pin.
