REMOVAL
1. Remove tire from vehicle with power tool.
2. Remove undercover with power tool.
3. Remove front cross bar.
4. Remove cotter pin at transve rse link, then loosen mounting nut.
5. Use a ball joint remover (SST) to remove transverse link from steering knuckle. Be careful not to damage ball joint boot.
CAUTION:
Tighten temporarily mounting nut to prevent damage to
threads and to prevent ball jo int remover (SST) from com-
ing off.

link.
7. Remove mounting bolts which are at the front of transverse link (mounting part with front suspension member) with power tool,
separate transverse link.
8. Remove transverse link from vehicle.
INSPECTION AFTER REMOVAL
Visual Inspection
 Check transverse link and bushing for deformation, cracks, or damage. If any non-standard condition is
found, replace it.
 Check boot of ball joint for cracks, or other damage, and also for grease leakage. If any non-standard condi-
tion is found, replace it.
Ball Joint Inspection
Manually move ball stud to confirm it moves smoothly with no binding.
Swing Torque Inspection
NOTE:
Before measurement, move ball joint at least ten times by hand to check for smooth movement.
 Hook spring balance at ball stud. Confirm spring balance measure- ment value is within the specifications when ball stud begins mov-
ing.
 If it is outside the specified range, replace transverse link assem- bly.
Rotating Torque Inspection

SERVICE INFORMATION FOR ELECTRICAL INCIDENT
The voltage value is based on the body ground.
*:If high resistance exists in the switch side circuit (caused by a single strand), terminal 1 does not detect battery voltage. Control unit
does not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not supply power to ligh t up the
lamp.
INPUT-OUTPUT VOLTAGE CHART
The voltage value is based on the body ground.
*:If high resistance exists in the switch side circuit (caused by a single strand), terminal 2 does not detect approx. 0V. Cont rol unit does
not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not control ground to light u p the lamp.
Control Units and Electrical PartsINFOID:0000000001325673
PRECAUTIONS
 Never reverse polarity of battery terminals.
 Install only parts specified for a vehicle.
 Before replacing the control unit, check the input and output and functions of the component parts.
 Do not apply excessive force when disconnecting a connector.
 Do not apply excessive shock to the control unit by dropping or hit- ting it.
 Be careful to prevent condensation in the control unit due to rapid temperature changes and do not let water or rain get on it. If water
is found in the control unit, dry it fully and then install it in the vehi-
cle.
 Be careful not to let oil to get on the control unit connector.
 Avoid cleaning the control unit with volatile oil.
 Do not disassemble the control unit, and do not remove the upper and lower covers.

AWD MODELS
INFINITI recommends that a dolly be used as illustrated when towing AWD models.
CAUTION:
Never tow AWD models with any of the wheels on the ground as this may cause serious and expen-
sive damage to the powertrain.
Vehicle Recovery (Freeing a Stuck Vehicle)INFOID:0000000001325685
Securely install the vehicle recovery hook stored with jacking tools.
Make sure that the hook is properly secured in the stored place after
use.
WARNING:
 Stand clear of a stuck vehicle.
 Do not spin your tires at high speed. This could cause them to
explode and result in serious injury. Parts of your vehicle
could also overheat and be damaged.
CAUTION:
 Tow chains or cables must be attached only to the vehicle recovery hooks or main struct ural members of the vehicle.
Otherwise, the vehicle body will be damaged.
 Do not use the vehicle tie downs to free a vehicle stuck in
sand, snow, mud, etc. Never to w the vehicle using the vehicle
tie downs or recovery hooks.
 Always pull the cable straight out from the front of the vehicle.
Never pull on the hook at an angle.
 Pulling devices should be rout ed so they do not touch any
part of the suspension, steer ing, brake or cooling systems.
 Pulling devices such as ropes or canvas straps are not rec- ommended for use in vehicle towing or recovery.
AUTOMATIC TRANSMISSION
To tow a vehicle equipped with an automatic tr ansmission, an appropriate vehicle dolly MUST be placed under
the towed vehicle's drive wheels. Always follow the dolly manufacture's recommendations when using their
product.
If the vehicle is stuck in sand, snow , mud, etc., use the following procedure:
1. Turn off the Vehicle Dynamic Control System.
2. Make sure the area in front and behind the vehicle is clear of obstructions.
