FRONT SUSPENSION ASSEMBLY
On-Vehicle Inspection and Service INFOID:0000000004305863
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 bet ween 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 Inspection INFOID:0000000004305864
PRELIMINARY INSPECTION WARNING:
Always adjust the alignment with the vehicle on a flat surface.
NOTE:
If alignment is out of specification, inspect and r eplace 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-6, " Inspection " .
4. Check the wheel bearing axial end play. Refer to FAX-6, " 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-19, " Wheelarch Height (Unladen*) " .
GENERAL INFORMATION AND RECOMMENDATIONS 1. A Four-Wheel Thrust Alignment should be performed. • This type of alignment is re commended 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 calib rated in order to give correct information.
• Check with the manufacturer of your specific a lignment 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-17, " 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. Axial end play : 0 mm (0 in)

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).
CAUTION:
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.
7. Use the formula below to calculate total toe-in. • If the total toe-in is outside the specification, adj ust toe-in by varying the length of between steering
outer socket and inner socket. SFA234AC
