Front Suspension PartsEES001GI
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, then
check ball joint end play. Refer to FAX-5, "
WHEEL BEARING
INSPECTION" and FSU-15, "Inspection" .
Make sure that the cotter pin is inserted (4x4 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 AlignmentEES001GJ
PRELIMINARY INSPECTION
WAR NIN G:
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 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 FAX-5, "
WHEEL BEARING INSPECTION" .
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 rear suspension member for any damage.
8. Check the vehicle height. Refer to FSU-21, "
Wheelarch Height (Unladen*1 )" .
Verify the level using Consult-II memory register 1103 and set to 0 ± 10 mm (0 ± 0.39 in) as necessary.
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.Suspension component torques : Refer to FSU-5,

Revision: October 20052005 QX56
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
socket.
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.
Any turning angles are not adjustable. If any of steering
angles are out of the specification, check if the following parts
are worn or damaged.
–Steering gear
–Steering column
–Front suspension components

Coil Spring
Check for cracks, deformation or other damage and replace if necessary.
Check the free spring height.
ASSEMBLY
1. When installing coil spring on shock absorber, it must be posi-
tioned as shown.
2. Install upper mounting insulator as shown in line with lower
shock absorber mount and step in shock absorber lower seat.
The step in the shock absorber lower seat faces outside of
vehicle.
3. Tighten the piston rod lock nut to specification. Refer to FSU-5,
"Components" .
Use a new piston rod lock nut for assembly.Front spring free height
