FINAL DRIVEPFP:38411
Assembly and Disassembly (RS5F51A)ECS008CA
PRE-INSPECTION

Check 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 differential case so that side gear to be measured faces upward.
3. Place the drift below and a dial gauge onto side gear. Move side
gear up and down, and measure the clearance.
CAUTION:
There should be no resistance and gears should rotate
freely.
4. If not within specification, adjust the clearance by changing side
gear 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 final gear mounting bolts, and then separate the final gear from differential case.
2. Remove differential side bearing (clutch housing side) using the
drift and pullers.
3. Remove differential side bearing (transaxle case side) using the
drift and pullers.

4. Remove retaining pin from differential case, and then remove
pinion mate shaft using a pin punch.
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

Check 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

Check 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 the procedure below.
Then select side gear thrust washer.
a. Upright the differential case so that its side gear to be measured
faces upward.
b. Place the drift below and a dial gauge onto side gears.
c. Move side gears up and down to measure end play, and select
thrust washer so that it satisfies the standard value. Refer to MT-
101, "DIFFERENTIAL SIDE GEAR THRUST WASHER" .
CAUTION:

There should be no resistance and gears should rotate
freely.

Place differential case upside down. Be sure to measure
end play for opposite side-gears likewise.

Only one thrust washer can be selected.
6. Install a new retaining pin into pinion mate shaft using a pin
punch.
CAUTION:
Do not reuse retaining pin.
7. Press in differential side bearing (transaxle case side) to differ-
ential case using the drifts.
