Oil Pump Clearance

Measure the clearance with feeler gauge.
–Clearance between oil pump outer rotor and oil pump body
(Position 1)
–Tip clearance between oil pump inner rotor and oil pump outer
rotor (Position 2)

Measure the clearance with feeler gauge and straightedge.
–Side clearance between oil pump inner rotor and oil pump body
(Position 3)
–Side clearance between oil pump outer rotor and oil pump body
(Position 4)

Calculate the clearance between oil pump inner rotor and oil pump body as follows:
OIL PUMP INNER ROTOR OUTER DIAMETER
–Measure the outer diameter of protruded portion of oil pump
inner rotor with micrometer. (Position 5) Standard : 0.114 - 0.200 mm (0.0045 - 0.0079 in)

Checking Power Steering Fluid and LinesALS000FV
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 PartsALS000FW
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.

14. Remove suspension arm and cotter pin at axle, then loosen mounting nut.
15. Use a ball joint remover (suitable tool) to remove suspension arm from axle. Be careful not to damage ball joint boot.
CAUTION:
Tighten temporarily mounting nut to prevent damage to threads and to prevent ball joint remover
(suitable tool) from coming off.
16. Remove axle from vehicle.
INSPECTION AFTER REMOVAL
Ball Joint Inspection
Check for boot breakage, axial looseness, and torque of suspension arm ball joint. Refer to RSU-11,
"INSPECTION AFTER REMOVAL" .
INSTALLATION

Refer to RAX-5, "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.

Perform final tightening of installation position of suspension links (rubber bushing) under unladen condi-
tions with tires on level ground, Check wheel alignment. Refer to RSU-5, "
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" .
