TRANSVERSE LINK
TRANSVERSE LINK
Removal and InstallationINFOID:0000000001703727
REMOVAL
1. Remove front tires using power tool.

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, "

REMOVAL
1. Separate intermediate shaft from steering gear pinion shaft. Refer to PS-9, "Removal and Installation" .
2. Remove front tires using power tool.
3. Remove the nut on the lower side of stabilizer connecting rod using power tool, and then remove stabilizer
connecting rod from stabilizer bar.
4. If necessary remove stabilize connecting rod upper nut using power tool. Separate stabilizer connecting
rod and strut.
5. Loose steering outer socket (1) nut.
6. Remove steering outer socket (1) from steering knuckle (2) so
as not to damage ball joint boot (3) using the ball joint remover
or suitable tool.
CAUTION:
Temporarily tighten the nut to prevent damage to threads
and to prevent the ball joint remover (suitable tool) from
suddenly coming off.
7. Remove rear torque rod. Refer to EM-72, "
Component" .
8. Set jack under front suspension member.
9. Remove the bolts of member stay, and then remove member stay.
10. Gradually lower front suspension member in order to remove
stabilizer bolts.
CAUTION:
Be careful not to lower it too far. (Do not over load the
links.)
11. Remove the bolts of stabilizer clamp, and then remove stabilizer
clamp and stabilizer bushing.
12. Remove stabilizer bar.
INSPECTION AFTER REMOVAL
Check stabilizer bar, stabilizer connecting rod, stabilizer bushing, and stabilizer clamp for deformation, cracks,
and damage. Replace it if necessary.
INSTALLATION
Installation is in the reverse order of removal.
• For tightening torques, refer to FSU-9, "
Component" . Tool number : HT72520000 (J-25730-A)

PRECAUTIONS
SERVICE INFORMATION
PRECAUTIONS
DescriptionINFOID:0000000001702421
Observe the following precautions to ensure safe and proper servicing. These precautions are not
described in each individual section.
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001702422
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
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 Necessary for Steering Wheel Rotation After Battery Disconnect
INFOID:0000000001702423
NOTE:
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
• Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position.
• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-III.

TOW TRUCK TOWING
Tow Truck TowingINFOID:0000000001702452
CAUTION:
• All applicable local laws regarding the towing operation must be obeyed.
• It is necessary to use proper towing equipment to avoid possible damage to the vehicle during tow-
ing operation. Towing is in accordance with Towing Procedure Manual at dealer.
• Always attach safety chains before towing.
• When towing, make sure that the transmission, steering system and power train are in good order. If
any unit is damaged, dollies must be used.
NISSAN recommends that the vehicle be towed with the driving (front) wheels off the ground as illustrated.
TOWING AN AUTOMATIC TRANSAXLE MODEL WITH FOUR WHEELS ON GROUND
CAUTION:
Never tow an automatic transaxle model with four wheels on the ground as this may cause serious
and expensive damage to the transaxle.
Vehicle Recovery (Freeing a Stuck Vehicle)INFOID:0000000001702453
• Tow chains or cables must be attached only to the main structural members of the vehicle.
• Pulling devices should be routed so they do not touch any part of the suspension, steering, brake or cooling
systems.
• Always pull the cable straight out from the front or rear of the vehicle. Never pull on the vehicle at an angle.
• Pulling devices such as ropes or canvas straps are not recommended for use in vehicle towing or recovery.
WARNING:
• Do not spin the tires at high speed. This could cause them to explode and result in serious injury.
Parts of the vehicle could also overheat and be damaged.
• Install removable recovery hook securely using wheel nut wrench.
