8. Remove cotter pin (1), and then loosen the nut.
9. Remove steering outer socket (2) from steering knuckle (3) so
as not to damage ball joint boot (4) using the ball joint remover
(suitable tool).
CAUTION:
Temporarily tighten the nut to prevent damage to threads
and to prevent the ball joint remover (suitable tool) from
suddenly coming off.
10. Remove drive shaft from wheel hub and bearing assembly.
11. Remove fixing nuts and bolts, and then remove shock absorber
arm. Refer to FSU-26, "
Components" .
12. Remove drive shaft from front final drive. (RH side)

Remove drive shaft from front final drive using the drive shaft
attachment [SST] and a drive shaft puller (suitable tool) while
inserting tip of the drive shaft attachment [SST] between
housing and front final drive as shown in the figure.
CAUTION:
Do not place drive shaft joint at an extreme angle when
removing drive shaft. Also be careful not to overextend side
shaft joint.
13. Remove fixing nuts and bolts, and then remove drive shaft from
vehicle. (LH side)
INSPECTION AFTER REMOVAL

Move joint up/down, left/right, and in the axial directions. Check for motion that is not smooth and for sig-
nificant looseness.

Check boot for cracks, damage, and leakage of grease.

Disassemble drive shaft and exchange malfunctioning part if
there is a non-standard condition.
INSTALLATION
CAUTION:
Always replace transaxle side oil seal with new one when installing drive shaft. Refer to FFD-11, "
SIDE
OIL SEAL" .

Installation is the reverse order of removal. For tightening torque refer to FA X - 11 , "COMPONENT" .

Place the protector [SST: KV38107900 ( – )] onto front final
drive to prevent damage to the oil seal while inserting drive
shaft. Slide drive shaft sliding joint and tap with a hammer to
install securely. (RH side)

PRECAUTIONS
Revision: 2007 April2007 M35/M45
PRECAUTIONSPFP:00001
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectNDS000EK
NOTE:

This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).

Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position.

Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-III.
Service Notice or PrecautionsNDS000EL

Check for the correct installation status prior to removal or disassembly. If matching marks are required,
be certain they do not interfere with the function of the parts when applied.

Overhaul should be done in a clean work area, it is preferable to work in dustproof area.

Before disassembly, using steam or white gasoline, completely remove sand and mud from the exterior of
the unit, preventing them from entering into the unit during disassembly or assembly.

Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
with a new ones if necessary.

Gaskets, seals and O-rings should be replaced any time when the unit is disassembled.

In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.

Clean and flush the parts sufficiently and blow-dry them.

Be careful not to damage sliding surfaces and mating surfaces.

When applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.

Always use shop paper for cleaning the inside of components.

Avoid using cotton gloves or shop rags to prevent entering of lint.

During assembly, observe the specified tightening torque, and apply new gear oil, petroleum jelly, or multi-
purpose grease as specified for each vehicle, if necessary.
