ON-VEHICLE SERVICE
Revision: October 20052005 QX56
ON-VEHICLE SERVICEPFP:00000
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,
