[REAR FINAL DRIVE: R200V]

DIFFERENTIAL ASSEMBLY

13. Put matching marks with paint.

14. Loosen screws on differential cases A and B.

15. Separate differential case A and B, then remove viscous cou-

pling, pinion mate gear, pinion mate thrust washer, side gear,
pinion mate shaft, circular clip and side gear thrust washer from
differential cases.

1.

Install side gear thrust washer with the same thickness as the
ones installed prior to disassembly or reinstall the old ones on
the side gear.

2.

Install side gear and thrust washer into differential case B.

CAUTION:

Make sure that the circular clip is installed to side gear.

3.

Install pinion mate assembly (pinion mate shaft, pinion mate
gears and pinion mate thrust washers) into differential case B.

CAUTION:

Install the pinion mate shaft groove side to side gear.

4.

Install viscous coupling into differential case B.

5.

Install side gear thrust washer with the same thickness as the
ones installed prior to disassembly or reinstall the old ones on
the viscous coupling.

6.

Align the matching marks and install differential case A into dif-
ferential case B.

7.

Measure side gear end play. If necessary, select the appropriate side gear thrust washer.

a.

Place differential assembly so that right side gear is on the upper side.

b.

Measure the clearance between right side gear back and differ-
ential case using feeler gauge, while rotating right side gear with
a suitable tool attached to splines.

CAUTION:

• Never place feeler gauge at groove side of differential

case.

• To prevent side gear from tilting, insert feeler gauges with the same thickness from both sides.

c.

If the back clearance is outside the specification, use a thicker/thinner side gear thrust washer to adjust.

CAUTION:

Standard

Side gear back clearance

: Refer to 

DLN-132, "Differ-

ential Side Gear Clear-
ance"

.

When the back clearance 
is large:

Use a thicker thrust wash-
er.

When the back clearance 
is small:

Use a thinner thrust wash-
er.

[REAR FINAL DRIVE: R200V]

DIFFERENTIAL ASSEMBLY

• Adjust the clearance with the left side gear thrust washer only.
• Only one side gear thrust washer can be selected.

8.

Align the matching mark of differential case with the mark of
drive gear, then place drive gear.

9.

Apply thread locking sealant into the thread hole of drive gear.
• Use Genuine High Strength Thread Locking Sealant or

equivalent. Refer to 

GI-15, "Recommended Chemical

Products and Sealants"

.

CAUTION:

Clean and degrease drive gear back and threaded holes
sufficiently.

10. Install drive gear on the mounting bolts.

CAUTION:

• Tighten bolts in a crisscross fashion.
• After tightening the bolts to the specified torque, tighten

the bolts additionally by turning the bolts 31 to 36
degrees.

11. Press side bearing inner races to differential case, using the drift

(A) [SST: KV38100300 (J-25523)] and the base (B) [SST:
ST33061000 (J-8107-2)].

CAUTION:

Never reuse side bearing inner race.

12. Install differential case assembly with side bearing outer races

into gear carrier.

13. Measure side bearing preload. If necessary, select the appropri-

ate side bearing adjusting washers. Refer to 

DLN-110, "A/T :

Adjustment"

.

14. Insert selected left and right side bearing adjusting washers in

place between side bearings and gear carrier.

15. Align matching marks on bearing cap with that on gear carrier.

16. Install bearing caps and tighten bearing cap mounting bolts.

17. Using the drift [SST: KV38100200 (J-26233)], drive side oil seals

until it becomes flush with the case end.

CAUTION:

• Never reuse oil seal.
• When installing, never incline oil seal.
• Apply multi-purpose grease onto oil seal lips, and gear oil

onto the circumference of oil seal.

18. Check and adjust drive gear runout, tooth contact, drive gear to

drive pinion backlash, and total preload torque. Refer to
