Checking Power Steering Fluid and LinesNLS00070
Check fluid level in reservoir tank with engine off.
Use “HOT” range at fluid temperatures of 50 to 80 °C (122 to 176 °F)
or “COLD” range at fluid temperatures of 0 to 30 °C (32 to 86 °F).
CAUTION:

Do not overfill.

Recommended fluid is Genuine NISSAN PSF or equivalent.
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS"


Check lines for improper attachment, leaks, cracks, dam-
age, loose connections, chafing and deterioration.

Check rack boots for accumulation of power steering fluid.
Axle and Suspension PartsNLS00071
Check front and rear axle and suspension parts for excessive play,
cracks, wear or other damage.

Shake each wheel to check for excessive play.

Check wheel bearings for smooth operation.

Check axle and suspension nuts and bolts for looseness.

Check strut (shock absorber) for oil leakage or other damage.

Check suspension ball joint for grease leakage and ball joint
dust cover for cracks or other damage.

Removal and InstallationNDS000AV
REMOVAL
1. Remove the front and rear engine undercover with a power tool.
2. Remove the front cross bar with a power tool. Refer to FSU-6, "
FRONT SUSPENSION ASSEMBLY" .
3. Remove the exhaust front tube bracket with a power tool. Refer to EX-3, "
EXHAUST SYSTEM" .
4. Disconnect the heated oxygen sensor harness connector.
5. Remove the exhaust front tube mounting nuts with a power tool. Refer to EX-3, "
EXHAUST SYSTEM" .
6. Remove the right bank three way catalyst with a power tool. Refer to EM-26, "
Removal and Installation"
(VQ35DE), EM-183, "Removal and Installation" (VK45DE).
7. Remove the power steering piping mounting bolts. Refer to PS-
41, "HYDRAULIC LINE" .
8. Remove the power steering gear box fixing bolts to secure work- ing area for removal of propeller shaft. Refer to PS-18, "
POWER
STEERING GEAR AND LINKAGE" .
CAUTION:
Be careful not to damage the steering gear box piping dur-
ing removal.
9. Put matching marks onto propeller shaft flange yoke and final drive companion flange.
CAUTION:
For matching mark, use paint. Do not damage propeller
shaft flange and companion flange.
10. Remove the propeller shaft fixing bolts.
11. Set the transmission jack at the transfer, remove rear engine mounting bolts, and then lower transmission jack about 40 - 50
mm (0.16 - 0.21 in).
12. Remove propeller shaft from the front final drive and transfer.
INSPECTION

Inspect propeller shaft runout at measuring point. If runout
exceeds specifications, replace propeller shaft assembly. For
measuring point, refer to PR-4, "
Propeller Shaft Runout Measur-
ing Point" .
