TRANSVERSE LINK
Removal and InstallationINFOID:0000000001703727
REMOVAL
1. Remove front tires using power tool.
2. Remove transverse link ball joint nut and bolt. Then, remove transverse link from steering knuckle.
3. Remove transverse link nuts and bolts, then remove transverse
link from front suspension member.
NOTE:
When removing LH transverse link it may be necessay to lower
the suspension member in order to remove bolts to avoid con-
tact with the transaxle.
a. Set jack under front suspension member.
b. Loosen RH upper link bolts, LH upper link bolt (front suspension
member side), front suspension member bolts (left/right). Lower
the front suspension member in order to remove transverse link
bolts.
4. Remove transverse link.
INSPECTION AFTER REMOVAL
Visual Inspection
Check the following:
• Transverse link and bushing for deformation, cracks or damage. Replace it if necessary.
• Ball joint boot for cracks or other damage, and also for grease leakage. Replace it if necessary.
Ball Joint Inspection
Manually move ball stud to confirm it moves smoothly with no binding.
Swing Torque Inspection
NOTE:
Before measurement, move ball stud at least ten times by hand to check for smooth movement.
• Hook a spring balance at the cutout on ball stud. Confirm spring
balance measurement value is within specifications when ball stud
begins moving.
• If it is outside the specified range, replace transverse link assem-
bly.
Axial End Play Inspection
• Move tip of ball stud in axial direction to check for looseness.
• If it is outside the specified range, replace transverse link assembly.
INSTALLATION
Installation is in the reverse order of removal.
• For tightening torque, refer to FSU-9, "
Component" .
• Perform final tightening of bolts and at the front suspension member installation position (rubber bushing)
under unladen conditions with tires on level ground. Check wheel alignment. Refer to RSU-2, "
Precaution for
Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"" .

peratures of 30 to 50°C (86 to 122°F) using the “COLD” range
on A/T fluid level gauge.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi-
tion. Leave selector lever in “P” position.
c. Check A/T fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe clean with lint-free cloth.
CAUTION:
When wiping the A/T fluid level gauge, always use lint-free
cloth.

low side of range, add A/T fluid to the A/T fluid charging pipe.
CAUTION:
Do not overfill.
4. Drive vehicle for approximately 5 minutes.
5. Re-check A/T fluid level at A/T fluid temperatures of 50 to 80°C (122 to 176°F) using “HOT” range on A/T
fluid level gauge.
CAUTION:
• When wiping the A/T fluid level gauge, always use lint-free cloth.
• Firmly fix the A/T fluid level gauge to the A/T fluid charging pipe using the stopper attached.
6. Check A/T fluid condition and make any necessary repairs. Refer to AT-48, "
Inspections Before Trouble
Diagnosis" . If the A/T fluid contains frictional material (clutches, bands, etc.), or if the A/T is repaired,
overhauled, or replaced, inspect and clean the A/T fluid cooler mounted in the radiator. Refer to AT-16, "
A/
T Fluid Cooler Cleaning" .
7. Install the removed A/T fluid level gauge into the A/T fluid charging pipe.
CAUTION:
Firmly fix the A/T fluid level gauge to the A/T fluid charging pipe using the stopper attached.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001703128
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001844076
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
PrecautionINFOID:0000000001703129
• If transaxle assembly is removed from the vehicle, always replace CSC (Concentric Slave Cylinder).
Installed CSC returns to the original position when removing transaxle assembly. Dust on clutch disc sliding
parts may damage CSC seal, and may cause clutch fluid leakage.
• Do not reuse transaxle oil.
• Drain, fill and check transaxle oil with the vehicle on level surface.
• During removal or installation, keep inside of transaxle clear of dust or dirt.
• Check for the correct installation orientation prior to removal or disassembly. If matching marks are required,
be certain they do not interfere with the function of the parts they are applied to.
• In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tight-
ening sequence is specified, follow it.
• Be careful not to damage the sliding surfaces and mating surfaces of parts.
