Pinion front bearing; make sure the J-34309-3 pinion front
bearing seat is secured tightly against the J-34309-2 gauge
anvil. Then turn the pinion front bearing pilot, J-34309-5, to
secure the bearing in its proper position.
Pinion rear bearing; the pinion rear bearing pilot, J-34309-8,
is used to center the pinion rear bearing only. The pinion rear
bearing locking seat, J-34309-4, is used to lock the bearing to
the assembly.
Installation of J-34309-9 and J-34309-16; place a suitable
2.5 mm (0.098 in) thick plain washer between J-34309-9 and
J-34309-16. Both surfaces of J-34309-9 and J-34309-16 must
be parallel with a clearance of 2.5 mm (0.098 in).
3. Install the pinion rear bearing inner race into gear carrier. Then
place the pinion preload shim selector tool, J-34309-1, gauge
screw assembly.
4. Assemble the pinion front bearing inner race and the J-34309-2
gauge anvil. Assemble them together with the J-34309-1 gauge
screw in gear carrier. Make sure that the pinion height gauge
plate, J-34309-16, will turn a full 360 degrees. Tighten the two
sections together by hand.
5. Turn the assembly several times to seat the bearings.
6. Measure the turning torque at the end of the J-34309-2 gauge
anvil using preload gauge.

10. Apply anti-corrosion oil to the thread and seat of drive pinion
lock nut, and temporarily tighten drive pinion lock nut to drive
pinion.
CAUTION:
Do not reuse drive pinion lock nut.
11. Adjust to the drive pinion lock nut tightening torque and pinion
bearing preload torque.
CAUTION:
Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.
If the 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 preload torque.
After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.
12. Install differential case assembly. Refer to RFD-33, "
Differential Assembly" .
CAUTION:
Do not install rear cover yet.
13. Check and adjust drive gear runout, tooth contact, drive gear to drive pinion backlash, and companion
flange runout. Refer to RFD-19, "
Drive Gear Runout" , RFD-20, "Tooth Contact" , RFD-21, "Backlash" ,
RFD-22, "
Companion Flange Runout" .
Recheck above items. Readjust the above description, if necessary.
14. Check total preload torque. Refer to RFD-19, "
Total Preload Torque" .
15. Install rear cover. Refer to RFD-33, "
Differential Assembly" .

Gear Clearance" .
6. Drive a lock pin into pinion mate shaft, using a punch.
Make sure lock pin is flush with differential case.
CAUTION:
Do not reuse lock pin.
7. Align the matching mark of differential case with the mark of
drive gear, then place drive gear.
8. Apply thread locking sealant into the thread hole of drive gear.

PRECAUTIONS
Revision: 2006 January2006 M35/M45
PRECAUTIONSPFP:00001
PrecautionsNES000J2
When installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
–Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
After servicing suspension parts, be sure to check wheel alignment.
Self-lock nuts are not reusable. Always use new ones when installing. Since new self-lock nuts are pre-
oiled, tighten as they are.

tool, and then remove shock absorber assembly from vehicle.
INSPECTION AFTER REMOVAL
Check shock absorber assembly for deformation, cracks, damage, and replace if there are.
Check welded and sealed areas for oil leakage, and replace if there are.
INSTALLATION
Installation is the reverse order of removal. For tightening torque. Refer to RSU-7, "Components" .
CAUTION:
Do not reuse non-reusable parts.
Perform final tightening of shock absorber assembly lower side (rubber bushing) under unladen condition
with tires on level ground. Check wheel alignment. Refer to RSU-5, "
Wheel Alignment Inspection" .
Adjust neutral position of steering angle sensor after checking the wheel alignment. Refer to BRC-6,
"Adjustment of Steering Angle Sensor Neutral Position" .
Disassembly and AssemblyNES000JB
DISASSEMBLY
CAUTION:
Make sure piston rod on shock absorber is not damaged when removing components from shock
absorber.
1. Remove mounting seal from mounting bracket.
2. Wrap a shop cloth around lower side of shock absorber and secure it in a vise.
CAUTION:
Do not set the cylindrical part of shock absorber in a vise.

PRE-CRASH SEAT BELTPFP:98845
Component Parts and Harness Connector LocationNHS0007X
System DescriptionNHS0007Y
Pre-crash seat belt system is adapted to front seat belts RH/LH.
When the pre-crash seat belt control unit judges the emergency braking operation, it gives the sense of
security by the motor built into the pre-crash seat belt retracting the shoulder belt and suppressing the
crew's posture change. Also, it eases the damage of the collision.
