Changing A/T FluidALS000GC
1. Warm up ATF.
2. Stop engine.
3. Remove the tightening bolt for ATF level gauge.
4. Drain ATF from drain plug and refill with new ATF. Always refill same volume with drained fluid.
To replace the ATF, pour in new fluid at the charging pipe with the engine idling and at the same time
drain the old fluid from the radiator cooler hose return side.
When the color of the fluid coming out is about the same as the color of the new fluid, the replacement
is complete. The amount of new transmission fluid to use should be 30 to 50% increase of the stipu-
lated amount.
CAUTION:
Use only Genuine NISSAN Matic J ATF. Do not mix with other fluid.
Using automatic transmission fluid other than Genuine NISSAN Matic J ATF will cause deterio-
ration in driveability and automatic transmission durability, and may damage the automatic
transmission, which is not covered by the warranty.
When filling ATF, take care not to splash heat generating parts such as exhaust with ATF.
Do not reuse drain plug gasket.
5. Run engine at idle speed for 5 minutes.
6. Check fluid level and condition. Refer to MA-28, "
Checking A/T Fluid" . If fluid is still dirty, repeat step 2.
through 5.
7. Install the removed ATF level gauge in the fluid charging pipe.

REMOVAL
1. Remove inner and outer balance weights from the road wheel.
CAUTION:
Be careful not to scratch the road wheel during removal.
2. Using releasing agent, remove double-faced adhesive tape from the road wheel.
CAUTION:
Be careful not to scratch the road wheel during removal.
After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road
wheel.
WHEEL BALANCE ADJUSTMENT
If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting,
select and adjust a drive-in weight mode suitable for road wheels.
1. Set road wheel on wheel balancer using the center hole as a guide. Start the tire balance machine.
2. When inner and outer unbalance values are shown on the wheel balancer indicator, multiply outer unbal-
ance value by 5/3 to determine balance weight that should be used. Select the outer balance weight with
a value closest to the calculated value above and install it to the designated outer position of, or at the
designated angle in relation to the road wheel.
CAUTION:
Do not install the inner balance weight before installing the outer balance weight.Oil grade and Viscosity:

POWER STEERING FLUID
Revision: 2004 November 2004 FX35/FX45
POWER STEERING FLUIDPFP:KLF20
Checking Fluid LevelAGS000GT
Stop engine before performing a fluid level check.
Ensure that fluid level is between the MAX range and MIN level.
Because fluid level differs within the HOT range and the COLD
range, check it carefully.
CAUTION:
Do not overfill the Max level.
Do not reuse any used power steering fluid.
Recommended fluid is Genuine NISSAN PSF or equivalent.
Checking Fluid LeakageAGS000GU
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 to 80° C (122 to
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-31, "
POWER STEERING OIL
PUMP" .
6. Check steering gear boots for accumulation of fluid indicating a from steering gear.
Air Bleeding Hydraulic SystemAGS000GV
Incomplete air bleeding causes the following. When this happens, bleed air again.
Generation of air bubbles in reservoir tank.
Generation of 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 low-level line. Check tank frequently and
add fluid as needed.
2. Run engine at idle speed. Turn steering wheel fully to the right and then fully to the left, and keep for about
three seconds. Then check whether a fluid leakage has occurred.
3. Repeat the 2nd procedure several times at about three seconds intervals.
CAUTION:
Do not hold steering wheel in the locked position more than 10 seconds. (There is the possibility
that oil pump may be damaged.)
4. Check generation of air bubbles and cloud in fluid.HOT : Fluid temperatures from 50 to 80 °C (122 to
176°F)
COLD : Fluid temperatures from 0 to 30°C (32 to 86°F)

STEERING WHEELPFP:48430
On-Vehicle Inspection and ServiceAGS000GW
CHECKING CONDITION OF INSTALLATION
Check installation condition of steering gear assembly, front suspension, axle and steering column.
Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.
Check if the mounting bolts for steering gear assembly are loose
or not. Refer to PS-19, "
POWER STEERING GEAR AND LINK-
AGE" .
CHECKING STEERING WHEEL PLAY
1. Set tires to the straight ahead, start engine, then turn steering wheel to the left and right lightly, and mea-
sure steering wheel movement on the outer circumference when steering wheel is turned up to the point
where tires start moving.
CHECKING NEUTRAL POSITION ON STEERING WHEEL
Check neutral position on steering wheel after confirming that front wheel alignment is correct. Refer to FSU-
6, "Wheel Alignment Inspection" .
1. Set vehicle to the straight direction, check if steering wheel is in the neutral position.
2. If it is not in the neutral position, remove steering wheel and reinstall it correctly.
3. If the neutral position cannot adjust in the two teeth of steering gear assembly, loosen outer socket lock
nuts of steering outer sockets, then adjust outer socket by the same amount in the opposite direction.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Remove driver air bag module from steering wheel. Refer to SRS-36, "
DRIVER AIR BAG MODULE" .
3. Start engine at idle, make steering fluid reach to normal operat-
ing temperature [50 to 80°C (122 to 176°F)], then check steering
wheel turning torque with pre-load gauge (SST).
4. If steering wheel turning force is out of the specification, check
relief hydraulic pressure of oil pump. Refer to PS-31, "
POWER
STEERING OIL PUMP" . End play of the axle direction for steering wheel : 0 mm (0 in)
