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
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
• Check tooth contact. Refer to

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