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-206,

"General Specification"

.

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-206, "Inspection and Adjustment"

.

• Check total preload. Refer to 

DLN-206, "Inspection and

Adjustment"

.

• Check tooth contact. Refer to 

DLN-206, "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-21,

"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.
