Changing Engine OilELS001GZ
WA RN ING:

Be careful not to burn yourself, as the engine and engine oil are hot.

Prolonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct
skin contact with used oil. If skin contact is made, wash thoroughly with soap or hand cleaner as
soon as possible.
1. Warm up the engine, and check for any oil leaks.
2. Stop the engine and wait for at least 10 minutes.
3. Remove the oil drain plug and oil filler cap to drain the old oil.
4. Install a new washer on the oil drain plug, then install the oil drain plug in the oil pan.
CAUTION:
Clean the drain plug and install with a new washer.
5. Refill the engine with new specified engine oil.
CAUTION:
The refill capacity depends on the oil temperature and drain time. Use the “Refill oil capacity” val-
ues as a reference and check the oil level using the dipstick when filling the engine with oil.
6. Warm up the engine and check the area around the drain plug and oil filter for any oil leaks.
7. Stop the engine and wait for more than 10 minutes.
8. Check the oil level using the dipstick as shown. Add oil as nec-
essary and install the oil filler cap.
CAUTION:
Do not overfill the engine with oil.

oil are hot.

When removing, prepare a shop cloth to absorb any
engine oil leakage or spillage.

Do not allow engine oil to adhere to the drive belts.

Completely wipe off any engine oil that adheres to the engine and the vehicle.
INSTALLATION
1. Remove foreign materials adhering to the oil filter installation surface.Oil drain plug : Refer to EM-73, "
CYLINDER BLOCK" .
Oil grade and viscosity : Refer to MA-11, "

POWER STEERING FLUID
Revision: October 20052005 QX56
POWER STEERING FLUIDPFP:KLF20
Checking Fluid LevelEGS000U9
Check fluid level, referring to the scale on reservoir tank.
Use HOT range for fluid temperatures of 50° – 80°C (122° – 176°F).
Use COLD range for fluid temperatures of 0° – 30°C (32° – 86°F).
CAUTION:

Do not overfill.

Do not reuse any used power steering fluid.

Recommended fluid is Genuine NISSAN PSF or equivalent.
Refer to MA-11, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS" .
Checking Fluid LeakageEGS000UA
Check the hydraulic piping lines for improper attachment and for
leaks, cracks, damage, loose connections, chafing or deterioration.
1. Run engine until fluid temperature reaches 50° – 80°C (122° –
176°F) in reservoir tank. Keep engine speed 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. (There is the possibility that oil pump may
be damaged.)
4. If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not over tighten con-
nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer to PS-26, "
POWER STEERING OIL
PUMP" .
6. Check steering gear boots for accumulation of fluid indicating a leak from the steering gear.
Air Bleeding Hydraulic SystemEGS000UB
Incomplete air bleeding causes the following. When this happens, bleed air again.

Air bubbles in reservoir tank.

Clicking noise in oil pump.

Excessive buzzing in oil pump.
NOTE:
When vehicle is stationary or while steering wheel is being turned slowly, some noise may be heard from
oil pump or gear. This noise is normal and does not affect any system.
1. Stop engine, and then turn steering wheel fully to right and left several times.
CAUTION:
Do not allow steering fluid reservoir tank to go below the MIN level line. Check tank frequently and
add fluid as needed.
2. Run engine at idle speed. Turn steering wheel fully right and then fully left, hold for about three seconds.
Then check for fluid leakage.
3. Repeat step 2 several times at about three second intervals.
CAUTION:
Do not hold steering wheel in the locked position for more than 10 seconds. (There is the possibil-
ity that oil pump may be damaged.)
4. Check for air bubbles or cloudy fluid.
5. If air bubbles or cloudiness still exists, stop engine, perform steps 2 and 3 again until air bubbles or cloud-
iness does not exist.
6. Stop engine, check fluid level.

2. Install the pinion mate shaft into the differential case so that it
meets the lock pin holes.
3. Adjust the clearance between rear face of side gear and thrust
washer by selecting the correct thickness side gear thrust
washer. Refer to RFD-27, "

WASHERS" .
Use two feeler gauges as shown to prevent the side gear from
leaning.
SIDE BEARING PRELOAD
NOTE:
A selection of carrier side bearing adjusting washers is required for completion of this procedure.
1. All parts must be clean. The bearings must be well lubricated
with light oil or DEXRON
TM type automatic transmission fluid.
2. Place the differential case assembly, with the side bearing outer
races installed, into the gear carrier.
3. Insert the left and right side bearing adjusting washers in posi-
tion between the side bearings and the gear carrier as shown.
