FRONT SUSPENSION ASSEMBLY
FRONT SUSPENSION ASSEMBLY
On-Vehicle Inspection and ServiceINFOID:0000000001703721
Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
INSPECTION OF LOWER BALL JOINT END PLAY
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Place an iron bar or similar tool between transverse link and steering knuckle.
3. Measure axial end play by prying it up and down.
CAUTION:
Be careful not to damage ball joint boot. Do not damage the installation position by applying
excessive force.
STRUT INSPECTION
Check for oil leakage, damage and replace as necessary.
Wheel Alignment InspectionINFOID:0000000001703722
PRELIMINARY INSPECTION
WARNING:
Always adjust the alignment with the vehicle on a flat surface.
NOTE:
If alignment is out of specification, inspect and replace any damaged or worn rear suspension parts before
making any adjustments.
1. Check and adjust the wheel alignment with the vehicle under unladen conditions. “Unladen conditions”
means that the fuel, coolant, and lubricant are full; and that the spare tire, jack, hand tools and mats are in
their designated positions.
2. Check the tires for incorrect air pressure and excessive wear.
3. Check the wheels for run out and damage. Refer to WT-5, "
Inspection" .
4. Check the wheel bearing axial end play. Refer to FA X - 5 , "
On-Vehicle Inspection and Service" .
5. Check the shock absorbers for leaks or damage.
6. Check each mounting point of the suspension components for any excessive looseness or damage.
7. Check each link, arm, and the suspension member for any damage.
8. Check the vehicle height. Refer to FSU-17, "
Wheelarch Height (Unladen*)" .
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 capable 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 alignment machine for their recommended Service/Cali-
bration Schedule.
THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to FSU-16, "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.Axial end play : 0 mm (0 in)

TRANSVERSE LINK
Removal and InstallationINFOID:0000000001703727
REMOVAL
1. Remove front tires using power tool.
2. Remove transverse link ball joint nut and bolt. Then, remove transverse link from steering knuckle.
3. Remove transverse link nuts and bolts, then remove transverse
link from front suspension member.
NOTE:
When removing LH transverse link it may be necessay to lower
the suspension member in order to remove bolts to avoid con-
tact with the transaxle.

INSPECTION AFTER REMOVAL
Visual Inspection
Check the following:
• Transverse link and bushing for deformation, cracks or damage. Replace it if necessary.
• Ball joint boot for cracks or other damage, and also for grease leakage. Replace it if necessary.
Ball Joint Inspection
Manually move ball stud to confirm it moves smoothly with no binding.
Swing Torque Inspection
NOTE:
Before measurement, move ball stud at least ten times by hand to check for smooth movement.
• Hook a spring balance at the cutout on ball stud. Confirm spring
balance measurement value is within specifications when ball stud
begins moving.
• If it is outside the specified range, replace transverse link assem-
bly.
Axial End Play Inspection
• Move tip of ball stud in axial direction to check for looseness.
• If it is outside the specified range, replace transverse link assembly.
INSTALLATION
Installation is in the reverse order of removal.
• For tightening torque, refer to FSU-9, "
Component" .
• Perform final tightening of bolts and at the front suspension member installation position (rubber bushing)
under unladen conditions with tires on level ground. Check wheel alignment. Refer to RSU-2, "

PERIODIC MAINTENANCE
Abbreviations: R = Replace. I = Inspect. Correct or replace if necessary. L = Lubricate.
(1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, change (not just inspect) oil (exc. LSD) at
every 30,000 miles (48,000 km) or 24 months, and change LSD gear oil every 15,000 miles (24,000 km) or 12 months.
(2) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, inspect CVT fluid deterioration with CON-
SULT-II every 60,000 miles (96,000 km), then change CVT fluid NS-2 if necessary. If CONSULT-II is not available, change (not just
inspect) CVT fluid NS-2 every 60,000 miles (96,000 km). Using transmission fluid other than Genuine NISSAN CVT Fluid NS-2 will
damage the CVT, which is not covered by the NISSAN new vehicle limited warranty.
(3) Refer to “Tire rotation” under the “GENERAL MAINTENANCE” heading earlier in this section.

STEERING WHEEL
STEERING WHEEL
On-Vehicle Inspection and ServiceINFOID:0000000001703859
CHECKING CONDITION OF INSTALLATION
• Check installation conditions of steering gear assembly, front suspension assembly, axle and steering col-
umn assembly.
• Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.
• Check steering gear assembly mounting bolts and nuts for looseness. Refer to PS-12, "
Removal and Instal-
lation" .
CHECKING STEERING WHEEL PLAY
• Turn steering wheel so that front wheels come to the straight-ahead position. Start engine and lightly turn
steering wheel to the left and right until front wheels start to move. Measure steering wheel movement on the
outer circumference.
• When the measurement value is outside the standard value, check backlash for each joint of steering col-
umn assembly and installation condition of steering gear assembly.
CHECKING NEUTRAL POSITION STEERING WHEEL
• Make sure that steering gear assembly, steering column assembly and steering wheel are installed in the
correct position.
• Perform neutral position inspection after wheel alignment. Refer to RSU-2, "
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"" .
• Set vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.
• Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if steer-
ing wheel is not in the neutral position.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Check steering wheel turning force when steering wheel has
been turned 360° from neutral position using suitable tool as
shown.
4. If steering wheel turning force is out of the specification, refer to
STC-6, "
How to Perform Trouble Diagnosis" .
CHECKING FRONT WHEEL TURNING ANGLE
Steering wheel axial end play : 0 mm (0 in)
Steering wheel play : 0 - 35 mm (0 - 1.38 in)
Steering wheel
turning force: Less than 36 N (3.7 kg-f, 8.2 lb-f)

• Check front wheel turning angle after toe-in inspection. Place front
wheels on turning radius gauges and rear wheels on stands.
Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.
• With the engine at idle, turn steering wheel from full left stop to full
right stop and measure the turning angles.
• Measure rack stroke if angles are outside the specified value.
• Disassemble steering gear assembly to check the cause that rack
stroke is outside of the standard.
• Steering angles are not adjustable. Check steering gear assembly,
steering column assembly and front suspension components for
wear or damage if any of the turning angles are different from the
specified value. Replace any of them, if any non-standard condi-
tion exists.

REMOVAL
NOTE:
When reconnecting spiral cable, secure cable with a tape so that case and rotating part keep aligned. This will
omit neutral position alignment procedure during spiral cable installation.
1. Set front wheels to straight-ahead position.
2. Remove driver air bag module. Refer to SRS-33
.
3. Remove steering wheel lock nut after steering is locked.
4. Remove steering wheel.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
Do not run spiral cable idle needlessly. And do not turn it more than necessary (or it leads to discon-
nection of the cable).
