6. Set a suitable jack to rear final drive assembly.
CAUTION:
Do not place a suitable jack on the rear cover (aluminum
case).
7. Remove the mounting bolts and nuts connecting to the suspen-
sion member, and remove rear final drive assembly.
CAUTION:
Secure rear final drive assembly to a suitable jack while
removing it.
INSTALLATION
Note the following, and installation is in the reverse order of removal.

Refer to RFD-19, "COMPONENTS" (R200 2-pinion) or RFD-39, "COMPONENTS" (R200V LSD) about
each tightening torque.

When installing breather hoses, refer to the figure.
CAUTION:
Make sure there are no pinched or restricted areas on the
breather hose caused by bending or winding when install-
ing it.
–For installation, the vehicle side end shall be inserted to suspen-
sion member. Install metal connector side of this hose to rear
cover by inserting it with aiming painted marking to the front of
vehicle.

When oil leaks while removing final drive assembly, check oil
level after the installation. Refer to RFD-9, "
Checking Differential
Gear Oil" .

Revision: 2006 November2007 350Z
ASSEMBLY INSPECTION AND ADJUSTMENT

Before inspection and adjustment, drain gear oil.
Total Preload Torque
1. Secure final drive assembly onto an attachment.
2. Remove side flanges.
3. Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
4. Rotate drive pinion at least 20 times to check for smooth opera-
tion of the bearing.
5. Measure total preload with the preload gauge.
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.
Drive Gear Runout
1. Remove rear cover. Refer to RFD-24, "Differential Assembly" .
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.Tool number : KV38100800 (J-25604-01)
Tool number : ST3127S000 (J-25765-A)
Total preload torque:
2.85 – 3.75 N·m (0.29 – 0.38 kg-m, 26 – 33 in-lb)
PDIA0635E
When the preload torque is large
On pinion bearings: Replace the collapsible spacer.
On side bearings: Use thinner side bearing adjusting washers by the same amount to
each side. Refer to RFD-60, "
Side Bearing Adjusting Washer" .
When the preload is small
On pinion bearings: Tighten the drive pinion lock nut.
On side bearings: Use thicker side bearing adjusting washers by the same amount to
each side. Refer to RFD-60, "
Side Bearing Adjusting Washer" .
Runout limit: 0.05 mm (0.0020 in) or less

Tooth Contact
1. Remove rear cover. Refer to RFD-24, "Differential Assembly" .
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.

4. If tooth contact is improperly adjusted, follow the procedure
below to adjust the pinion height (dimension X).

If the tooth contact is near the face (face contact), or near the
heel (heel contact), thicken pinion height adjusting washers to
move drive pinion closer to drive gear.
Refer to RFD-60, "
Pinion Height Adjusting Washer" .

If the tooth contact is near the flank (flank contact), or near the
toe (toe contact), thin pinion height adjusting washers to move
drive pinion farther from drive gear.
Refer to RFD-60, "
Pinion Height Adjusting Washer" .
Backlash
1. Remove rear cover. Refer to RFD-24, "Differential Assembly" .
2. Fit a dial indicator to the drive gear face to measure the back-
lash.

If the backlash is outside of the specified value, change the
thickness of side bearing adjusting washer.
CAUTION:
Do not change the total amount of washers as it will change the bearing preload.
SDIA0517E
PDIA0440E
PDIA0441E
Backlash: 0.10 – 0.15 mm (0.0039 – 0.0059 in)
When the backlash is large:
Make drive gear back side adjusting washer thicker,
and drive gear tooth side adjusting washer thinner by
the same amount. Refer to RFD-60, "
Side Bearing
Adjusting Washer" .
When the backlash is small:
Make drive gear back side adjusting washer thinner,
and drive gear tooth side adjusting washer thicker by
the same amount. Refer to RFD-60, "
Side Bearing
Adjusting Washer" .
