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 mea-
surement value is within the specifications when ball stud begins
moving.

If it is outside the specified range, replace transverse link
assembly.
Rotating Torque Inspection

Attach mounting nut to ball stud. Check that rotating torque is
within the specifications with a preload gauge (SST).

If it is outside the specified range, replace transverse link
assembly.
Axial End Play Inspection

Move tip of ball joint in axial direction to check for looseness.

If it is outside the specified range, replace transverse link assembly.
INSTALLATION

Refer to FSU-8, "Removal and Installation" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

After removing/installing or replacing suspension components, check wheel alignment. Refer to FSU-6,
"Wheel Alignment Inspection" .

After adjusting wheel alignment, adjust neutral position of steering angle sensor. Refer to BRC-6, "Adjust-
ment of Steering Angle Sensor Neutral Position" .

LIFTING POINTPFP:00000
Commercial Service Tools NAS0006P
CAUTION:

Every time the vehicle is lifted up, maintain the complete vehicle curb condition.

Since the vehicle's center of gravity changes when removing main parts on the front side (engine,
transmission, suspension etc.), support a jack up point on the rear side garage jack with a mission
jack or equivalent.

Since the vehicle's center of gravity changes when removing main parts on the rear side (rear axle,
suspension, etc.), support a jack up point on the front side garage jack with a mission jack or
equivalent.

Be careful not to smash or do not do anything that would affect piping parts.
Garage Jack and Safety Stand NAS0006Q
WARNING:

Park the vehicle on a level surface when using the jack. Make sure to avoid damaging pipes,
tubes, etc. under the vehicle.

Never get under the vehicle while it is supported only by the jack. Always use safety stands when
you have to get under the vehicle.

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) NAS0006U
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 structural 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 tow the vehicle using the vehi-
cle tie downs or recovery hooks.

Always pull the cable straight out from the front of the vehi-
cle. Never pull on the hook at an angle.

Pulling devices should be routed so they do not touch any
part of the suspension, steering, brake or cooling systems.

Pulling devices such as ropes or canvas straps are not rec-
ommended for use in vehicle towing or recovery.
