REAR SUSPENSION ASSEMBLY

On-Vehicle Inspection and ServiceEES0007F
Check axle and suspension parts for excessive play, wear, and damage.

Move rear wheels (RH/LH) to check abnormal free play.

Retighten all nuts and bolts to the specified torque.

Check strut for oil leakage and damage.
Wheel AlignmentEES0007G
DESCRIPTION

Measure wheel alignment under unladen conditions. “Unladen conditions” means that fuel, coolant, and
lubricant are full. However, spare tyre, jack, and hand tools should be unloaded.
PRELIMINARY INSPECTION
1. Check the tyre for improper air pressure and wear.
2. Check road wheels for runout.
3. Check wheel bearing axial endplay.
4. Check strut operation.
5. Check each mounting point of axle and suspension for looseness and deformation.
6. Check each link and arm for cracks, deformation, and other damage.
7. Check the vehicle posture.
CAMBER
Camber is preset at factory and cannot be adjusted.

If the camber is not within specification, inspect and replace any damaged or worn rear suspension parts.
TOE-IN
Measure toe-in using the following procedure.

Always perform following procedure on a flat surface.

Make sure that no person is in front of the vehicle before push-
ing it.
1. Bounce rear of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of tread (rear side) of both tyre at the
same height as hub center. This mark is a measuring points.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS002F9
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Brake SystemEFS000BZ

Clean dust on brake pads, shoes, drums, and back plates with a vacuum dust collector. Do not blow with
compressed air.

Recommended fluid is brake fluid “DOT 3” or “DOT 4”.

Never reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas such as the body. If brake fluid is splashed or spilled
on painted areas, wipe it off and flush the area with water immediately.

Use only clean brake fluid when cleaning master cylinder and disc brake components.

Never use mineral oils such as gasoline or kerosene to clean. They will ruin the rubber parts and cause
improper operation.

Always use a flare nut torque wrench to securely tighten brake
tube flare nuts.

Brake system is an important safety part. If a brake fluid leak is
detected, always disassemble the related parts. If damage,
deformation or excessive wear is detected, replace affected
parts with new ones.

Before starting operation, be sure to turn the ignition switch OFF
and disconnect the ABS actuator and control module connector
or battery cables.

When installing brake piping, be sure to check torque.SBR820BA
