FRONT FINAL DRIVE ASSEMBLY
ASSEMBLY INSPECTION AND ADJUSTMENT
 Before inspection and adjustment, drain gear oil.
Total Preload Torque
1. Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
2. Rotate drive pinion at least 20 times to check for smooth operation of the bearing.
3. Measure total preload with preload gauge.NOTE:
Total preload torque = Pinion bearing preload torque + Side
bearing preload torque
 If measured value is out of the specification, disassemble it to check and adjust each part. Adjust the pinion bearing preload and
side bearing preload.
Adjust the pinion bearing preload first, then adjust the side bearing preload.

PRECAUTIONS
CautionINFOID:0000000001327533
• When installing rubber bushings, final tightening must be carried out under unladen conditions with tires on
ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
 Unladen conditions mean that fuel, engine coolant and l ubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
 After servicing suspension parts, be sure to check wheel alignment.
 Caulking nuts are not reusable. Always use new ones w hen installing. Since new caulking nuts are pre-oiled,
tighten as they are.
 Avoid burden to front cross bar.

Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
INSPECTION 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 bet ween 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.
STRUT INSPECTION
 Check strut for oil leakage, damage and replace if there are. Refer to FSU-10.
Wheel Alignment InspectionINFOID:0000000001327538
DESCRIPTION
 Measure wheel alignment under unladen conditions.
NOTE:
Unladen conditions mean that fuel, engine coolant, and l ubricant are full. Spare tire, jack, hand tools and
mats are designated positions.
PRELIMINARY CHECK
 Check tires for improper air pressure and wear.
 Check road wheels for runout.
 Check wheel bearing axial end play.
 Check ball joint axial end play of compression rod, upper link, and steering knuckle
 Check shock absorber operation.
 Check each mounting part of axle and suspension for looseness and deformation.
 Check each link, rod and member for cracks, deformation and other damage.
 Check vehicle posture.
GENERAL INFORMATION AND RECOMMENDATIONS
 A four-wheel thrust alignment should be performed.
- This type of alignment is recomm ended for any NISSAN/INFINITI vehicle.
- The four-wheel “thrust” process helps ensure that t he vehicle is properly aligned and the steering wheel is
centered.
- The alignment rack itself should be capable of accepting any NISSAN/INFINITI vehicle.
- The rack should be checked to ensure that it is level.
 Make sure the machine is properly calibrated.
- Your alignment equipment should be regularly ca librated in order to give correct information.
- Check with the manufacturer of your specific equi pment for their recommended Service/Calibration Sched-
ule.
THE ALIGNMENT PROCESS
IMPORTANT:
Use only the alignment specificati ons listed in this Service Manual.
 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 machine that operate these indicators may not be cor-
rect.
- This may result in an ERROR.
 Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com-
pensate” the sensors (alignment targets or head units). DO NOT use this “Rolling Compensation”
method. Axial end play : 0 mm (0 in)
