grease leakage.
+Check connection with steering column for looseness.
STEERING LINKAGENJST0037S02+Check ball joint, dust cover and other component parts for
looseness, wear, damage or grease leakage.
YST003
Checking Fluid LevelNJST0012Check fluid level, referring to the scale on reservoir tank.
Use ªHOTº range for fluid temperatures of 50 to 80ÉC (122 to
176ÉF).
Use ªCOLDº range for fluid temperatures of 0 to 30ÉC (32 to 86ÉF).
CAUTION:
+Do not overfill.
+Recommended fluid is DEXRON
TMIII or equivalent. Refer
to MA-16, ªFluids and Lubricantsº.
YST006
YST007
Checking Fluid LeakageNJST0013Check the lines for improper attachment and for leaks, cracks,
damage, loose connections, chafing and deterioration.
1. Run engine between idle speed and 1,000 rpm.
Make sure temperature of fluid in oil tank rises to 60 to 80ÉC
(140 to 176ÉF).
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each ªlockº position for five seconds
and carefully check for fluid leakage.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 15 seconds.
4. If fluid leakage at connectors is noticed, loosen flare nut and
then retighten.
Do not overtighten connector as this can damage O-ring,
washer and connector.
5. If fluid leakage from power steering pump is noticed, check
power steering pump. Refer to ST-25.
6. Check rack boots for accumulation of power steering fluid.

Bleeding Hydraulic SystemNJST00141. Raise front end of vehicle until wheels are clear of the ground.
2. Add fluid into oil tank to specified level. Then quickly turn steer-
ing wheel fully to right and left and lightly touch steering stop-
pers.
Repeat steering wheel operation until fluid level no longer
decreases.
3. Start engine.
Repeat step 2. above.
+Incomplete air bleeding will cause the following to occur. When
this happens, bleed air again.
a) Air bubbles in reservoir tank
b) Clicking noise in oil pump
c) Excessive buzzing in oil pump
Fluid noise may occur in the valve or oil pump. This is common
when the vehicle is stationary or while turning the steering wheel
slowly. This does not affect the performance or durability of the
system.
SST491B
SST090B
Checking Steering Wheel Turning ForceNJST00151. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating tempera-
ture. [Make sure temperature of fluid is approximately 60 to
80ÉC (140 to 176ÉF).]
Tires need to be inflated to normal pressure.
4. Check steering wheel turning force when steering wheel has
been turned 360É from the neutral position.
Steering wheel turning force:
39 N (4 kg, 9 lb) or less
5. If steering wheel turning force is out of specification, check
rack sliding force.
a. Disconnect steering column lower joint and knuckle arms from
the gear.
b. Start and run engine at idle to make sure steering fluid has
reached normal operating temperature.
c. Pull tie-rod slowly to move it from neutral position to±11.5 mm
(±0.453 in) at speed of 3.5 mm (0.138 in)/s. Check that rack
sliding force is within specification.
Average rack sliding force:
Sedan
152 - 240 N (15.5 - 24.5 kg, 34 - 54 lb)
Hatchback
132 - 308 N (13.5 - 31.4 kg, 30 - 69 lb)
Maximum force deviation:
Sedan
98 N (10 kg, 22 lb)
Hatchback
176 N (17.9 kg, 39 lb)
d. Check sliding force outside the above range at rack speed of
40 mm (1.75 in)/s.

Rack sliding force (Sedan only):
Not more than 294 N (30 kg, 66 lb)
Maximum force deviation:
147 N (15 kg, 33 lb)
6. If rack sliding force is not within specification, overhaul steer-
ing gear assembly.
7. If rack sliding force is OK, inspect steering column. Refer to
ST-14.
SST834-I
Checking Hydraulic SystemNJST0016Before starting, check belt tension, driving pulley and tire pressure.
1. Set Tool. Open shut-off valve. Then bleed air. Refer to ªBleed-
ing Hydraulic Systemº, ST-8.
2. Run engine at idle speed or 1,000 rpm.
Make sure temperature of fluid in tank rises to 60 to 80ÉC (140
to 176ÉF).
WARNING:
Warm up engine with shut-off valve fully opened. If engine is
started with shut-off valve closed, fluid pressure in oil pump
increases to maximum. This will raise oil temperature abnor-
mally.
3. Check pressure with steering wheel fully turned to left and right
positions with engine idling at 1,000 rpm.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 15 seconds.
Oil pump maximum standard pressure:

2, 1,261 - 1,362 psi)
+If pressure reaches maximum operating pressure, system is
OK.
+If pressure increases above maximum operating pressure,
check power steering pump flow control valve. Refer to ST-25.
4. If power steering pressure is below the maximum operating
pressure, slowly close shut-off valve and check pressure
again.
CAUTION:
Do not close shut-off valve for more than 15 seconds.
+If pressure increases to maximum operating pressure, gear is
damaged. Refer to ªRemoval and Installationº, ST-17.
+If pressure remains below maximum operating pressure, pump
is damaged. Refer to ªDisassemblyº, ST-26.
5. After checking hydraulic system, remove Tool and add fluid as

11. Check rack sliding force on vehicle as follows:
a. Install steering gear onto vehicle, but do not connect tie-rod to
knuckle arm.
b. Connect all piping and fill with steering fluid.
c. Start engine and bleed air completely.
d. Disconnect steering column lower joint from the gear.
e. Keep engine at idle and make sure steering fluid has reached
normal operating temperature.
f. Pull tie-rod slowly to move it from neutral position to±11.5 mm
(±0.453 in) at speed of 3.5 mm (0.138 in)/s. Check that rack
sliding force is within specification.

g. Check sliding force outside above range at rack speed of 40
mm (1.57 in)/s.
Maximum rack sliding force (Sedan only):
294 N (30 kg, 66 lb)
Maximum force deviation (Sedan only):
147 N (15 kg, 33 lb)
