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 al l control units using CONSULT-III.

• When installing the rubber bushings, the final tightening must be done under unladen condition and with the
tires on level ground. Oil will shorten the life of the rubber bushings, so wipe off any spilled oil immediately.
• Unladen condition means the fuel tank, engine coolant and lubricants are at the full specification. The spare
tire, jack, hand tools, and mats are in their designated positions.
• After installing suspension components, check the wheel alignment.
• Caulking nuts are not reusable. Always use new caulking nuts for installation. New caulking nuts are pre- oiled, do not apply any additional lubrication.

REAR SUSPENSION ASSEMBLY
On-Vehicle Inspection and ServiceINFOID:0000000005931084
Make sure the mounting conditions (looseness, backlash) of each component and component conditions
(wear, damage) are within specifications.
SHOCK ABSORBER INSPECTION
Check shock absorber for oil leakage, damage and replace it if necessary.
Wheel AlignmentInspectionINFOID:0000000005931085
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
PRELIMINARY
Check the following:
1. Tires for improper air pressure and wear.
2. Road wheels for runout. Refer to WT-6
.
3. Wheel bearing axial end play. Refer to RAX-6, "
On-Vehicle Inspection and Service" .
4. Shock absorber operation.
5. Each mounting part of suspension for looseness and deformation.
6. Rear suspension beam for cracks, deformation, and other damage.
7. Vehicle height (posture).
GENERAL INFORMATION AND RECOMMENDATIONS
1. A Four-Wheel Thrust Alignment should be performed. • This type of alignment is recommended for any NISSAN vehicle.
• The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel
is centered.
• The alignment machine itself should be ca pable of accepting any NISSAN vehicle.
• The alignment machine should be checked to ensure that it is level.
2. Make sure the alignment machine is properly calibrated. • Your alignment machine should be regularly calibrated in order to give correct information.
• Check with the manufacturer of your specific al ignment machine for their recommended Service/Cali-
bration Schedule.
THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to RSU-13, "Wheel
Alignment (Unladen*)" .
1. When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or minus, Go/No Go). Do NOT use these indicators.
• The alignment specifications programmed into your alignment machine that operate these indicators may not be correct.
• This may result in an ERROR.
2. Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com- pensate” the sensors (alignment targets or head units). Do NOT use this “Rolling Compensation”
method.
• Use the “Jacking Compensation” method. After inst alling the alignment targets or head units, raise the
vehicle and rotate the wheels 1/2 turn both ways.
• See Instructions in the alignment machine you are using for more information.

Removal and InstallationINFOID:0000000005931090
REMOVAL
1. Remove wheel and tire using power tool.
2. Separate parking brake rear cable from rear drum brake and rear suspension beam. Refer to PB-5, "
On-
Vehicle Service".
3. Remove wheel sensor and wheel sensor harness from wheel hub and bearing assembly and rear suspen-
sion beam. Refer to BRC-33, "
Removal and Installation".
4. Remove lock plate and separate brake tube from brake hose. Refer to BR-12, "
Rear Brake Tube and Hose".
5. Remove wheel hub and bearing assembly and back plate. Refer to RAX-6, "
On-Vehicle Inspection and Service".
6. Set jack under rear suspension beam.
7. Remove coil spring (left/right). Refer to RSU-11, "
Removal and
Installation".
8. Remove bolts between body and rear suspension beam bracket. Refer to RSU-8, "
Component".
9. Gradually lower the jack, and then remove rear suspension beam from vehicle.
10. Remove the rear suspension beam bracket bolt and nut, and then remove rear suspension beam bracket
from rear suspension beam. Refer to RSU-8, "
Component".
11. Remove brake tube protector from rear suspension beam.
INSPECTION AFTER REMOVAL
Check components for deformation, cracks, and other damage, and replace if necessary.
INSTALLATION
Installation is in the reverse order of removal.
• For tightening torque, refer to RSU-8, "
Component".
• Refill with new brake fluid and bleed air. Refer to BR-9, "
Bleeding Brake System".
• Tighten wheel nuts to specification. Refer to WT-7, "
Adjustment".
• Check the following after finishing work.
- Parking brake operation (stroke): Refer to PB-5, "
On-Vehicle Service".
- Wheel sensor harness for proper connection: Refer to BRC-33, "
Removal and Installation".
• Perform final tightening of rear suspension beam and rear suspen-
sion beam bracket (rubber bushing) under unladen conditions with
tires on level ground.

Service Notice or Precaution for EPS SystemINFOID:0000000005931271
CAUTION:
Check or confirm the following item wh en performing the trouble diagnosis.
• Check any possible causes by interviewing the symptom and it’s condition from the customer if any
malfunction, such as EPS warn ing lamp turns ON, occurs.
• Check if air pressure and size of tires are proper, the specified part is used for the steering wheel,
and control unit is genuine part.
• Check if the connection of steer ing column assembly and steering gear assembly is proper (there is
not looseness of mounting bolts, damage of rods, boots or sealants, and leakage of grease, etc).
• Check if the wheel alignment is adjusted properly.
• Check if there is any damage or modification to su spension or body resulting in increased weight or
altered ground clearance.
• Check if installation conditions of each link and suspension are proper.
• Check if the battery voltage is proper
• Check connection conditions of each connector are proper.
• Before connecting or disconnect ing the EPS control unit har-
ness connector, turn ignition switch “OFF” and disconnect
battery ground cable. Because battery voltage is applied to
EPS control unit even if igniti on switch is turned “OFF”.
• When connecting or disconnect ing pin connectors into or
from EPS control unit, take care not to damage pin terminals
(bend or break).
When connecting pin connectors, make sure that there are no
bends or breaks on EPS control unit pin terminal.
• Before replacing EPS control unit, perform EPS control unit input/output signal inspectio n and make sure whether EPS
control unit functions properly or not. Refer to STC-20, "
Ref-
erence Value".
