POWER STEERING FLUID AND LINES : Inspection
INFOID:0000000009464588
FLUID LEVEL
Check power steering fluid level at the scale on reservoir tank cap
indicator.
• Check power steering fluid level with engine stopped and the fluid temp between 0 – 30 ° C (32 – 86 ° F).
• Power steering fluid level should be between the hatching area of the indicator on the power steering reservoir tank cap.
CAUTION:
• Do not overfill.
• Do not reuse used power steering fluid.
• Recommended power steering fluid is Genuine NISSAN E-
PSF or equivalent. Refer to MA-11, "FOR USA AND CANADA :
Fluids and Lubricants".
FLUID LEAKAGE
Check the power steering hydraulic system for leaks, cracks, dam-
age, loose connections, chafing or det erioration. Repair or replace
as necessary.
1. Start engine and allow engine to idle.
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each “lock” position for five seconds to check fluid leakage.
CAUTION:
Do not hold steering wheel in a locked position for more
than 10 seconds. Damage to power steering oil pump may
occur.
4. If power steering fluid leakage at connections is noticed, loosen flare nut and retighten.
CAUTION:
Do not over tighten flare nut as damage to O-ring and connection can occur.
5. If power steering fluid leakage from the power steer ing oil pump is noticed, repair connection or replace
power steering oil pump. Refer to ST-15, "Inspection"
.
6. Check steering gear boots for accumulation of power steering fluid. Power steering fluid indicates a leak from the power steering gear, replace as necessary. Refer to ST-36, "Removal and Installation"
.
AXLE AND SUSPENSION PARTS
AXLE AND SUSPENSION PARTS : InspectionINFOID:0000000009464589
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.
