3.

Put matching mark on the end of drive pinion. The matching
mark should be in line with the matching mark A on companion
flange.

CAUTION:

For matching mark, use paint. Do not damage companion
flange and drive pinion.

NOTE:
The matching mark A on the final drive companion flange indi-
cates the maximum vertical runout position.
When replacing companion flange, matching mark is not neces-
sary.

4.

Remove companion flange using the suitable puller.

5.

Press drive pinion assembly out of gear carrier.

CAUTION:

Do not drop drive pinion assembly.

6.

Remove front oil seal.

7.

Remove side oil seal.

8.

Remove pinion front bearing inner race.

9.

Remove collapsible spacer.

10. Remove pinion rear bearing inner race and drive pinion height

adjusting washer with the replacer.

11. Tap pinion front/rear bearing outer races uniformly a brass rod or

equivalent to removed.

CAUTION:

Be careful not to damage gear carrier.

REAR FINAL DRIVE ASSEMBLY

INSPECTION AFTER DISASSEMBLY

Clean up the disassembled parts. Then, inspect if the parts are worn or damaged. If so, follow the measures
below.

ADJUSTMENT AND SELECTION OF ADJUSTING WASHERS
Differential Side Gear Clearance

●

Assemble the differential parts if they are disassembled. Refer to 

RFD-35, "Differential Assembly"

 .

1.

Place differential case straight up so that side gear to be mea-
sured comes upward.

Content

Conditions and Measures

Hypoid gear

●

If the gear teeth do not mesh or line-up correctly, determine the cause and adjust or replace as nec-
essary.

●

If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new 
drive gear and drive pinion as a set.

Bearing

●

If any chipped (by friction), pitted, worn, rusted or scratched mark, or unusual noise from the bearing 
is observed, replace as a bearing assembly (as a new set).

Side gear and Pinion mate 
gear

●

If any cracks or damage on the surface of the tooth is found, replace.

●

If any worn or chipped mark on the contact sides of the thrust washer is found, replace.

Side gear thrust washer and 
pinion mate thrust washer

●

If it is chipped (by friction), damaged, or unusually worn, replace.

Oil seal 

●

Whenever disassembled, replace.

●

If wear, deterioration of adherence (sealing force lips), or damage is detected on the lips, replace 
them.

Differential case

●

If any wear or crack on the contact sides of the differential case is found, replace.

Companion flange

●

If any chipped mark (about 0.1 mm, 0.004 in) or other damage on the contact sides of the lips of the 
companion flange is found, replace.

2.

Using feeler gauge, measure the clearance between side gear
back and differential case at 3 different points, while rotating
side gear. Average the 3 readings, and then measure the clear-
ance of the other side as well.

CAUTION:

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

3.

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

RFD-60,

"Side Gear Thrust Washer"

 .

CAUTION:

Select a side gear thrust washer for right and left individu-
ally.

Side Bearing Preload

●

Selecting carrier side bearing adjusting washers is required for successful completion of this procedure.

1.

Make sure all parts are clean. Also, make sure the bearings are
well lubricated with gear oil.

2.

Place the differential case, with side bearings and bearing races
installed, into gear carrier.

3.

Insert left and right original side bearing adjusting washers in
place between side bearings and gear carrier.

Side gear back clearance specification:

0.2 mm (0.008 in) or less.
(Each gear should rotate smoothly without excessive 
resistance during differential motion.)

When the back clearance is large:

Use a thicker thrust washer.

When the back clearance is small:

Use a thinner thrust washer.
