On-Vehicle Inspection and Service INFOID:0000000004305854
• Check the axle and suspension parts for excessive play, wear, or damage.
• Shake each rear wheel to check for excessive play as shown.
REAR WHEEL BEARING INSPECTION • Move wheel hub and bearing assembly in the axial direction by hand. Make sure the axial end play is within specification.
• Check that the wheel hub bearing operates smoothly.
• Replace the wheel hub assembly if the axial end play e xceeds specification, or if the wheel bearing does not
turn smoothly. Refer to RAX-5, " Removal and Installation " .
CAUTION:
The wheel hub assembly does not requ ire maintenance. If any of the following symptoms are noted,
replace the wheel hub assembly.
• Growling noise is emitted from th e wheel hub bearing during operation.
• Wheel hub bearing dr ags or turns roughly.

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.
Precaution for Rear Suspension INFOID:0000000004305875
• 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 l ubricants 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.

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 alignm ent 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.
CAMBER INSPECTION

RSU
N
O P
• Measure camber of both right and left wheels with a suitable align-
ment gauge.
• If it is out of the specificati on value, inspect and replace any dam-
aged or worn rear suspension parts.
TOE-IN INSPECTION Measure toe-in using following procedure. If it is out of the specification, inspect and replace any damaged or
worn rear suspension parts.
WARNING:
• Always perform the following procedure on a flat surface.
• Make sure that no person is in fron t of vehicle before pushing it.
1. Bounce the rear of vehicle up and down to stabilize the vehicle height (posture).
2. Push vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of both tires at the same height of hub center. These are measuring points.
4. Measure distance (A) from rear side.
5. Push vehicle slowly ahead to rotate wheels 180 degrees (1/2 turn). If wheels have rotated more than 180 degrees (1/2 turn),
try the above procedure again from the beginning. Never push
vehicle backward.
6. Measure distance (B) from front side. Camber : Refer to
