Front Suspension Parts
INFOID:0000000003939318
Check front suspension parts for excessive play, cracks, wear and
other damage.
• Shake each front wheel to check for excessive play. If looseness is
noted:
- inspect wheel bearing end play. Refer to
.
- check ball joint end play. Refer to
• Make sure that the cotter pin is inserted in drive shaft end (4WD
only).
• Retighten all nuts and bolts to the specified torque.
• Check shock absorber for oil leakage and other damage.
• Check suspension ball joint for grease leakage and ball joint dust
cover for cracks and other damage.
Front Wheel Alignment
INFOID:0000000003939319
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
.
4.
Check the wheel bearing axial end play. Refer to
FAX-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-25, "Wheelarch Height (Unladen*1)"
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 Instruction. Refer to
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 installing 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 AND CASTER
1.
Measure camber and caster of both the right and left wheels
with a suitable alignment gauge and adjust as necessary to
specification.
NOTE:
Some vehicles may be equipped with straight (non-adjustable)
lower link bolts and washers. In order to adjust camber and
caster on these vehicles, first replace the lower link bolts and
washers with adjustable (cam) bolts and washers.
2.
If outside of the specified value, adjust camber and caster using
the adjusting bolts in the front lower link.
CAUTION:
After adjusting the camber then check the toe-in.
NOTE:
Camber changes about 3' (0.05
°
) minutes with each graduation
of one adjusting bolt. Refer to table below for examples of lower
link adjusting bolt effect on camber and caster.
3.
Tighten the adjusting bolt nuts to specification. Refer to

ON-VEHICLE SERVICE
WARNING:
• Always perform the following procedure on a flat surface.
• Make sure that no person is in front of the vehicle before pushing it.
1.
Bounce the front of vehicle up and down to stabilize the vehicle height (posture).
2.
Push the vehicle straight ahead about 5 m (16 ft).
3.
Put a mark on base line of the tread (rear side) of both front tires
at the same height as hub center as shown. These marks are
measuring points.
4.
Measure the distance “A” on the rear side of the front tires as
shown.
5.
Push the vehicle slowly ahead to rotate the wheels 180
°
degrees (1/2 a turn).
CAUTION:
If the wheels have rotated more than 180
°
degrees (1/2
turn), start this procedure again from the beginning. Never
push the vehicle backward.
6.
Measure the distance “B” on the front side of the front tires at the
same marks as shown. Total toe-in is calculated as “A” – “B”.
7.
Adjust the toe-in by varying the length of the steering outer tie-
rods.
a.
Loosen the outer tie-rod lock nuts.
b.
Adjust the toe-in by screwing the outer tie-rods in or out.
c.
Tighten the outer tie-rod lock nuts to specification.
FRONT WHEEL TURNING ANGLE
NOTE:
Check front wheel turning angle after the toe-in inspection.
1.
Place front wheels on turning radius gauges in straight ahead
position and rear wheels on stands so that vehicle can be level.
Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.
2.
Start engine and run at idle, turn steering wheel all the way right
and left, measure the turning angle.

UPPER BALL JOINT AND LOWER BALL JOINT
UPPER BALL JOINT AND LOWER BALL JOINT
Inspection
INFOID:0000000003939320
• Check the ball joint for excessive play. Replace the upper or lower link assembly if any of the following
exists:
- Ball joint stud is worn.
- Ball joint is hard to swing.
- Ball joint play in axial directions or end play is excessive.
SWINGING FORCE
NOTE:
Before checking the axial forces and end play, turn the lower ball joint at least 10 revolutions so that the ball
joint is properly broken in.
1.
Measure the ball joint swinging force using a suitable tool.
• Measure at the cotter pin hole for upper ball joint as shown.
• Measure at the groove for lower ball joint as shown.
2.
Verify the ball joint swinging force is within specification.
TURNING FORCE
NOTE:
Before checking the axial forces and end play, turn the lower ball joint at least 10 revolutions so that the ball
joint is properly broken in.
