Infiniti G35 (V35) Sedan. Manual - part 424

DLN-130

< DISASSEMBLY AND ASSEMBLY >

[FRONT FINAL DRIVE: F160A]

DIFFERENTIAL ASSEMBLY

Never reuse O-ring.

22. Check and adjust drive gear runout, tooth contact, drive gear to drive pinion backlash, and total preload

torque. Refer to 

DLN-130, "Adjustment"

.

Recheck above items. Readjust the above description, if necessary.

23. Apply sealant to mating surface of carrier cover.

• Use Genuine Silicone RTV or equivalent. Refer to 

GI-15,

"Recommended Chemical Products and Sealants"

.

CAUTION:

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

24. Install carrier cover on gear carrier and tighten mounting bolts.

Adjustment

INFOID:0000000000957362

TOTAL PRELOAD TORQUE

• Before inspection and adjustment, drain gear oil.

1.

Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.

2.

Rotate drive pinion at least 20 times to check for smooth opera-
tion of the bearing.

3.

Measure total preload with preload gauge (A) [SST:
ST3127S000 (J-25765-A)].

NOTE:
Total preload torque = Pinion bearing preload torque + Side
bearing preload torque
• If measured value is out of the specification, disassemble it to check and adjust each part. Adjust the

pinion bearing preload and side bearing preload.
Adjust the pinion bearing preload first, then adjust the side bearing preload.

Standard

Total preload torque

: Refer to 

DLN-144, "Pre-

load Torque"

.

PDIA0792J

When the preload torque is large

On pinion bearings:

Decrease the drive pinion bearing adjusting washer and drive pinion 
adjusting washer thickness. 

On side bearings:

Increase the side bearing adjusting shim thickness.

When the preload torque is small

SIDE BEARING PRELOAD

• Before inspection and adjustment, drain gear oil.
1.

Remove carrier cover and side retainer. Refer to 

DLN-123, "Disassembly"

.

2.

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

3.

Place the differential case assembly into gear carrier.

4.

Install side bearing adjusting shim before disassembling or shim
which thickness is the same as the one before disassembling.

5.

Install side retainer assembly to gear carrier.

CAUTION:

Never install O-ring.

6.

Install side retainer mounting bolts to the specified torque.

7.

Measure the turning torque of the gear carrier at the drive gear
mounting bolts with a spring gauge [SST: 

—

 (J-8129)].

On pinion bearings:

Increase the drive pinion bearing adjusting washer and drive pinion 
adjusting washer thickness.

On side bearings:

Decrease the side bearing adjusting shim thickness.

Specification

: 34.2 – 39.2 N (3.5 – 4.0 kg, 
7.7 – 8.8 lb) of pulling force 
at the drive gear bolt

DIFFERENTIAL ASSEMBLY

8.

If the turning torque is outside the specification, use a thicker/
thinner side bearing adjusting shim to adjust.

9.

Record the total amount of shim thickness required for the cor-
rect carrier side bearing preload.

DRIVE GEAR RUNOUT

1.

Remove carrier cover. Refer to 

DLN-123, "Disassembly"

.

2.

Fit a dial indicator to the drive gear back face.

3.

Rotate the drive gear to measure runout.

• If the runout is outside of the repair limit, check drive gear

assembly condition; foreign material may be caught between
drive gear and differential case, or differential case or drive
gear may be deformed, etc.

CAUTION:

Replace drive gear and drive pinion gear as a set.

TOOTH CONTACT

• Before inspection and adjustment, drain gear oil.

1.

Remove carrier cover. Refer to 

DLN-123, "Disassembly"

.

2.

Apply red lead to drive gear.

CAUTION:

Apply red lead to both the faces of 3 to 4 gears at 4 loca-
tions evenly spaced on drive gear.

3.

Rotate drive gear back and forth several times, check drive pin-
ion gear to drive gear tooth contact.

CAUTION:

Check tooth contact on drive side and reverse side.

If the turning torque is less than the specified range:

Decrease the side bearing adjusting shim thickness.

If the turning torque is greater than the specification:

Increase the side bearing adjusting shim thickness.
