Infiniti G35 (V35) Sedan. Manual - part 427

DLN-142

< DISASSEMBLY AND ASSEMBLY >

[FRONT FINAL DRIVE: F160A]

DRIVE PINION

3.

Temporarily tighten removed drive pinion lock nut to drive pinion.
NOTE:
Use removed drive pinion lock nut only for the preload measure-
ment.

4.

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

5.

Tighten to drive pinion lock nut, while adjust pinion bearing pre-
load torque.

CAUTION:

• Adjust to the lower limit of the drive pinion lock nut tight-

ening torque first.

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

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

6.

If the pinion bearing preload torque is outside the specification,
use a thicker/thinner drive pinion bearing adjusting washer and
drive pinion adjusting washer to adjust. Refer to Refer to Service Manual and Refer to Service Manual.

7.

Remove companion flange, after adjustment.

COMPANION FLANGE RUNOUT

1.

Fit a dial indicator onto the companion flange face (inner side of
the propeller shaft mounting bolt holes).

2.

Rotate companion flange to check for runout.

3.

Fit a test indicator to the inner side of companion flange (socket
diameter).

4.

Rotate companion flange to check for runout.

5.

If the runout value is outside the runout limit, follow the procedure below to adjust.

a.

Check for runout while changing the phase between companion flange and drive pinion by 90

°

 step, and

search for the position where the runout is the minimum.

b.

If the runout value is still outside of the limit after the phase has been changed, possible cause will be an
assembly malfunction of drive pinion and pinion bearing and malfunction of pinion bearing. Check for
these items and repair if necessary.

A: Preload gauge [SST: ST3127S000 (J-25765-A)]

Standard

Pinion bearing preload

: Refer to 

DLN-144, "Pre-

load Torque"

.

When the preload torque is large:

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

When the preload is small:

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

Inspection After Disassembly

INFOID:0000000000957368

Clean up the disassembled parts. Then, inspect if the parts are worn or damaged. If so, follow the measures
below.

Content

Conditions and Measures

Hypoid gear

• If the gear teeth do not mesh or line-up correctly, determine the cause and adjust or replace as nec-

essary.

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

drive gear and drive pinion as a set.

Bearing

• If any chipped (by friction), pitted, worn, rusted or scratched mark, or unusual noise from the bearing 

is observed, replace as a bearing assembly (as a new set).

Side gear and Pinion mate 
gear

• If any cracks or damage on the surface of the tooth is found, replace.
• If any worn or chipped mark on the contact sides of the thrust washer is found, replace.

Side gear thrust washer and 
pinion mate thrust washer

• If it is chipped (by friction), damaged, or unusually worn, replace.

Oil seal 

• Whenever disassembled, replace.
• If wear, deterioration of adherence (sealing force lips), or damage is detected on the lips, replace them.

Differential case

• If any wear or crack on the contact sides of the differential case is found, replace.

Companion flange

• If any chipped mark (about 0.1 mm, 0.004 in) or other damage on the contact sides of the lips of the 

companion flange is found, replace.
