Drive Pinion and Drive Gear

• If the gear teeth do not mesh or line-up correctly, replace with new rear final drive assembly. Refer to 

DLN-

254, "Removal and Installation"

.

• If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new rear final

drive assembly. Refer to 

DLN-254, "Removal and Installation"

.

Bearings

• If bearings are chipped (by friction), pitted, worn, rusted, scratched, or unusual noise is coming from the

bearing, replace with new rear final drive assembly. Refer to 

DLN-254, "Removal and Installation"

.

Differential Case Assembly

• If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new rear final

drive assembly. Refer to 

DLN-254, "Removal and Installation"

.

• If the movement is not smooth when pushing cam ring of differential case assembly by hand. Replace with

new rear final drive assembly. Refer to 

DLN-254, "Removal and Installation"

.

Companion Flange

• If any chips (about 0.1mm, 0.004 in) or other damage on the companion flange surface which contacts the

front oil seal lips are found, replace with new one. Refer to 

DLN-255, "Disassembly and Assembly"

.

ASSEMBLY

Drive Pinion Assembly

1.

Install drive pinion front bearing thrust washer.

2.

Apply multi-purpose grease to new front oil seal lip. Install front
oil seal into gear carrier using Tool.

CAUTION:

• Do not reuse front oil seal.
• Do not incline the new front oil seal when installing.
• Apply multi-purpose grease to the lips of the new front oil

seal.

3.

Install new collapsible spacer to drive pinion. And then install
drive pinion assembly into gear carrier.

CAUTION:

• Do not reuse collapsible spacer.
• Do not damage front oil seal.

4.

Install a new oil seal/dust shield.

5.

Install the companion flange onto the drive pinion while aligning
the matching marks. Then tap the companion flange using suit-
able tool.

CAUTION:

Do not damage companion flange or front oil seal.

REAR FINAL DRIVE ASSEMBLY

6.

Apply anti-corrosive oil to the threads of the drive pinion and the
seating surface of the new drive pinion lock nut and new drive
pinion lock nut washer. Then adjust the drive pinion lock nut
tightening torque using suitable tool (A), and check the drive pin-
ion bearing preload torque using Tool (B). Refer to 

DLN-264,

"Inspection and Adjustment"

.

CAUTION:

• Do not reuse drive pinion lock nut or drive pinion lock nut

washer.

• Apply anti-corrosive oil to the threads of the drive pinion

and the seating surface of the new drive pinion lock nut.

• Adjust the drive pinion lock nut tightening torque to the

lower limit first. Do not exceed the drive pinion lock nut
specified torque.

• If the drive pinion bearing preload torque exceeds the

specified value, replace collapsible spacer and tighten it
again to adjust. Do not loosen drive pinion lock nut to
adjust the drive pinion bearing preload torque.

• After adjustment, rotate drive pinion back and forth 2 to 3

times to check for unusual noise, rotation malfunction,
and other malfunctions.

Differential Assembly

1.

Apply gear oil to side bearings. Install differential case assembly
with side bearing outer races into gear carrier.

2.

Align paint matching mark on side bearing caps with that on
gear carrier and install side bearing caps on gear carrier.

CAUTION:

Do not tighten side bearing cap bolts at this point. This
allows further tightening of side bearing adjusters.

3.

Tighten each side bearing adjusters using Tool.

• Adjusting backlash of drive gear and drive pinion. Refer to

DLN-264, "Inspection and Adjustment"

.

• Check total preload. Refer to 

DLN-264, "Inspection and

Adjustment"

.

• Check tooth contact. Refer to 

DLN-264, "Inspection and

Adjustment"

.

4.

Apply a bead of sealant to the mating surface of the carrier
cover as shown.
• Use Genuine Silicone RTV or equivalent. Refer to 

GI-22,

"Recommended Chemical Products and Sealants"

.

CAUTION:

Remove any old sealant adhering to the mating surfaces.
Also remove any moisture, oil, or foreign material adhering
to the application and mating surfaces.

5.

Install the carrier cover to the gear carrier. Tighten the bolts to
the specified torque.
