4.
Install the pinion mate shaft and align the lock pin hole on the
pinion mate shaft with the lock pin hole on the differential case.
5.
Measure the side gear end play. If necessary, select the appro-
priate side gear thrust washers. Refer to
6.

10. Install side bearing adjusters into gear carrier.
11. Apply differential gear oil to the side bearings, and install the dif-
ferential case assembly with the side bearing outer races into
the gear carrier.
CAUTION:
Do not reuse side bearing outer race when replacing side
bearing inner race (replace as a set).
12. Install the side bearing caps with the matching marks aligned.
NOTE:
Do not tighten at this step. This allows further tightening of side
bearing adjusters.
13. Tighten each side bearing adjuster alternately turning drive gear.
14. Check and adjust tooth contact, backlash, drive gear runout and total preload torque. Refer to
.
Recheck above items.
• After adjusting tooth contact and backlash secure side bearing
adjuster with screws and tighten side bearing cap bolt to the
specified torque. Refer to
DLN-345, "Disassembly and Assem-
.
15. Apply multi-purpose grease to the lips of the new side oil seal. Then drive the new side oil seal in evenly to
the gear carrier using suitable tool.
CAUTION:
• Do not reuse side oil seal.
• Do not incline the new side oil seal when installing.

16. Install the extension tube with a new O-ring.
CAUTION:
• Do not reuse O-ring.
• If the extension tube is being replaced, install a new axle
shaft bearing.
17. Apply 3 mm (0.12 in) 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.
18. Install the carrier cover to the gear carrier. Tighten the bolts to
the specified torque. Refer to
19. Install side shaft and side flange.

PRECAUTIONS
Precaution for Servicing Rear Final Drive
INFOID:0000000001297284
• Before starting diagnosis of the vehicle, understand the symptoms well. Perform correct and systematic
operations.
• Check for the correct installation status prior to removal or disassembly. When matching marks are required,
be certain they do not interfere with the function of the parts they are applied to.
• Overhaul should be done in a clean work area, a dust proof area is recommended.
• Before disassembly, completely remove sand and mud from the exterior of the unit, preventing them from
entering into the unit during disassembly or assembly.
• Always use shop paper for cleaning the inside of components.
• Avoid using cotton gloves or a shop cloth to prevent the entering of lint.
• Check appearance of the disassembled parts for damage, deformation, and abnormal wear. Replace them
with new ones if necessary.
• Gaskets, seals and O-rings should be replaced any time the unit is disassembled.
• Clean and flush the parts sufficiently and blow them dry.
• Be careful not to damage sliding surfaces and mating surfaces.
• When applying sealant, remove the old sealant from the mating surface; then remove any moisture, oil, and
foreign materials from the application and mating surfaces.
• In principle, tighten nuts or bolts gradually in several steps working diagonally from inside to outside. If a
tightening sequence is specified, observe it.
• During assembly, observe the specified tightening torque.
• Add new differential gear oil, petroleum jelly, or multi-purpose grease, as specified.
