Make sure that the mounting conditions (looseness, backlash) of each component and component conditions
(wear, damage) are normal.
WHEEL BEARING INSPECTION

Move wheel hub and bearing assembly in the axial direction by hand. Make sure there is no looseness of
wheel bearing.

Rotate wheel hub and make sure that is no unusual noise or other irregular conditions. If there is any of
irregular conditions, replace wheel hub and bearing assembly

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.
