Removal
1. Remove tires from vehicle with power tool.
2. Remove undercover with power tool.
3. Remove cotter pin. Then remove lock nut from drive shaft with power tool.
4. Remove wheel sensor harness fr om strut assembly. Refer to BRC-52
.
CAUTION:
Do not pull on wheel sensor harness.
5. Remove brake hose lock prate. Then remove brake hose from strut assembly. Refer to BR-10
.
6. Remove fixing bolts and nuts between strut assembly and steering knuckle with power tool.
7. Using a puller (suitable tool), remove drive shaft from steering knuckle.
CAUTION:
When removing drive shaf t, do not apply an excessive
angle to drive shaft joint. Al so be careful not to excessively
extend slide joint.
8. Pry off drive shaft from front final drive assembly side as shown in the figure.
INSPECTION AFTER REMOVAL
 Move joint up/down, left/right, and in the axial directi on. Check for any rough movement or significant loose-
ness.
 Check boot for cracks or other damage, and also for grease leak- age.
 If a trouble is found, disassemble drive shaft, and then replace with
new one.
INSTALLATION
 Refer to "Removal and installation (Right Side)" for ti ghtening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.
 Check the following item after service.

FRONT SUSPENSION ASSEMBLY
On-Vehicle Inspection and ServiceINFOID:0000000001327537
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)
