CAMSHAFT
• Measure the inner diameter of camshaft bracket with a bore gauge
(A).
CAMSHAFT JOURNAL OIL CLEARANCE
• (Oil clearance) = (Camshaft bracket inner diameter) – (Camshaft journal diameter)
• If it exceeds the limit, replace camshaft or cylinder head, or both.
NOTE:
Camshaft bracket cannot be replaced as a single part, because it is machined together with cylinder head.
Replace whole cylinder head assembly.
Camshaft End Play
1. Install camshaft in cylinder head.
2. Install dial indicator in thrust direction on front end of camshaft.
Read the end play of dial indicator (A) when camshaft is moved
forward/backward (in direction to axis).
• Measure the following parts if out of the standard.
- Dimension “A” for groove of cylinder head No. 1 journal
- Dimension “B” for camshaft flange
• Apply the standards above, and then replace camshaft and/or
cylinder head, if necessary.
Camshaft Sprocket Runout
1. Put V-block on precise flat table, and support No. 2 and 5 journals of camshaft.
CAUTION:
Never support No. 1 journal (on the side of camshaft sprocket) because it has a different diameter
from the other four locations.

• Measure the outer diameter of crankshaft main journals with a
micrometer (A).
• If out of the standard, measure the main bearing oil clearance.
Then use undersize bearing. Follow the "MAIN BEARING OIL
CLEARANCE" procedure.
CRANKSHAFT PIN JOURNAL DIAMETER
• Measure the outer diameter of crankshaft pin journal with a micrometer.
• If out of the standard, measure the connecting rod bearing oil clearance. Then use undersize bearing. Follow
the "CONNECTING ROD BEARING OIL CLEARANCE" procedure.
OUT-OF-ROUND AND TAPER OF CRANKSHAFT
• Measure the dimensions at four different points as shown on each
main journal and pin journal with a micrometer.
• Out-of-round is indicated by the difference in dimensions between
“X” and “Y” at “A” and “B”.
• Taper is indicated by the difference in dimension between “A” and
“B” at “X” and “Y”.
• If the measured value exceeds the limit, correct or replace crankshaft.
• If corrected, measure the bearing oil clearance of the corrected main journal and/or pin journal. Then select
main bearing and/or connecting rod bearing. Follow the "MAIN BEARING OIL CLEARANCE" and/or "CON-
NECTING ROD BEARING OIL CLEARANCE" procedures.
CRANKSHAFT RUNOUT
• Place a V-block on a precise flat table to support the journals on
the both end of the crankshaft.
• Place a dial indicator (A) straight up on the No. 3 journal.
• While rotating crankshaft, read the movement of the pointer on the
dial indicator. (Total indicator reading)
• If it exceeds the limit, replace crankshaft.

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)

REAR WINDOW GLASS AND MOLDING
Sedan
REMOVAL
1. If equipped, remove the rear wiper arm and motor. Refer to WW-31, "Removal and Installation" .
2. Remove the connectors and grounds for the rear window defogger.
• Remove glass using piano wire or power cutting tool and an inflat-
able pump bag.
• If the rear window glass is to be reused, mark the body and the
glass with mating marks.
WARNING:
When cutting the glass from the vehicle, always wear safety
glasses and heavy gloves to help prevent glass splinters from
entering your eyes or cutting your hands.
CAUTION:
• When a windshield glass is to be reused, do not use a cutting
knife or power cutting tool.
• Be careful not to scratch the glass when removing.
• Do not set or stand the glass on its edge. Small chips may develop into cracks.
