Note these items during disassembly:' lf an intact airbag assembly has been removed from a scrapped vehicle or has been found defective or damaged dur-ing transit, storage or service. it should be deployed (see section 24),a Before removing the gearbox, remove the driver.s airbag assembly and steering wheel.. After installing the gearbox, check the wheel alignment and adjust if necessary.
SRS components are located in this area. Review the SRS component locations, precautions, and procedures an the SRssection (24) before performing repairs or servrce.

Troubleshooting
General Troubleshootin g
Check the following before you begin:
. Has the suspension been modified in a way that would affect steering?
. Are tire sizes, tire variety and air pressure correct?
. ls the steering wheel original equipment or equivalent?
. ls the power steering pump belt properly adjusted?
. ls steering fluid reservoir filled to proper level?
. ls the engine idle speed correct and steady?
Hard Steering (Check the power assist, see page 17-12. lf the force is over 29 N (3.0 kgl 6.6 lbfl, proceed with this troubleshooting.i
Abnormalthiidpressure (Iluidpressure is toohigh)

Check the pump fluid pressure(see page 17-16 or 17-17).Measure steady state lluid pres-
sure at idle with the pressure con-trol valve and the shut-off valve (it
so equipped) fully open.The fluid pressure should be 1,500kPa (15 kgf/cm,,213 psi)or less.

Check the flow control valve (see page 17 26).. Check the valv€ lor smooth movement in the hous-ing.. Check the relief valve for leaks.
Check the pump fluid pressure(see page 17-16 or l7-17).Measure pump relief pressure atidle with the pressure controlvalve and the shut'off valve lil soequipped) fully closed.The fluid pressure should be 6,9007,800 kPa (70 - 80 kgflcm,, 1,000- 1,140 psi).

Troubleshooting
Noise and Vibration
NOTE: Pump noise in first 2 - 3 minutes after starting in cold weather is normal.
Humming
Rattle or chattering
Humming due to pulsation of fluid is normal, particularly when the wheel isturned with the vehicle stooDed.
lf equipped with automatic trans-mission, the hum could be thetorque converter or pump noase.
Confirm by temporarily removingthe pump belt.
Feed hose (high-pressure) touch-ing the frame.Beposition the feed hose.
Loose steering shaft connector,tie-rod, or balljoint.Check and tighten, or replaceparts as necessary,
Column shaft wobbling.Roplace the column assembly.
Check the rack guide for properadjustment (see page 17-15).Adjust, if necessary.
Rattling sound and feeling when turning the steering wheel right and left with th€engine OFF is normal.
Pump noise, though not loud, from the valve body unit can be heard when turn-ing the steering wheel to full lock in either direction. This is normal. Do not holdthe steering wheel at full lock lor more than five seconds when inspecting.

Check the fluid lev€1.lt low, fill the reservoir to theproper level. and check for leaks.Tighten or roplace as necessary,
Cavitation caused by air bubblesin the fluid.
Check for a crushed inlet hose ora loose hose clamp allowing airinto the suction side of the system. Check the reservoir forcracks. Tighten or replace as nec-
Check the drive shaft oil seal.
Pump noise up to 2 - 3 minutesafter starting in cold weather isnormal, Compare pump noise atoperatrng temperature to anothervehicle.
ll pump noise is abnormally loud,remove and inspect the pump forwear and damage (see page 17-251.
Tighten or replace the pulley.lI shaft is loose, replace thepump.

Troubleshooting
Fluid Leaks
Check the gearbox assembly for oil leaks carefully. Oil can leak out ot various points, depending on location of the faulty
oil seals/seal rings. Check the following before removing the gearbox from the frame.
Steering GearboxLeaking from the oil seal on thetop of the valve housing.Replace the valve oil seal fromthe valve housing.
Leaking from cylinder end intoleft tie rod boot.Replace the valve oil seal fromthe pinion shaft.
Replace the cylinder end seal onthe valve body unit side.
Leaking from cylinder end intoright tie-rod boot.Replace the cylinder end seal onthe cylinder end side.
Leaking lrom the shaft upper endsection or pin engagement sec-tion of the pinion shaft.Replace the valve body unit.
Tighten the connector. It it's stillleaking, replace the line, cylinderor valve housing.
Leaking from cylinder line A or Bconnections (at tlare nut).
Leaking caused by a damagedcylinder line A or B.Replace cylinder line A or B.
Leaking from pump outlet hoseand return line joint fitting on thevalve body unit {at tlare nut}.
Tighten the connector. ll it's stillleaking, replace the line, joint fit-ting or valve housing,

Inspection and Adjustment
Steering Operation
Place the front wheels in the straight ahead position.
and measure the distance the steering wheel can be
turned without moving the front wheels.
ROTATIONAL PLAY: 0 - 10 mm (0 - 0.39 inl
lf the play exceeds the limit, perform rack guide adjust-
ment (see page 17-15).
lf the play is still excessive after rack guide adjustment,
inspect the steering linkage and gearbox as described
on the next page.

Power Assist Check with
Vehicle Parked
1. Check the power steering fluid level (see page 17-
15) and pump belt tension (see page 17-14).
2. Start the engine, allow it to idle, and turn the steer-
ing wheel from lock-toiock several times to warm
up the fluid.
3. Aftach a spring scale to the steering wheel, With the
engine idling and the vehicle on a clean. dry floor,
pull the scale as shown and read it as soon as the
tires begin to turn.
SPRINGSCALE(Commercially
available)
The scale should read no more than 29 N (3.0 kgf,
6.6 lbfl. lf it reads more, check the gearbox and
oumo.

Inspection and Adjustment
Pump Belt
When using a new belt. first adjust the deflection or ten-
sion to the values for the new belt, then readjust the
deflection or tension to the values for the used belt after
running engine for five minutes.
Inspection
Note these items during inspection:
a lf there are cracks or any damage evident on the belt,
replace it with a new one.
. Follow the manufacturer's instructions lor the tension
gauge.
'1. Remove the P/S reservoir from the bracket, and set
it aside.
2. Attach the belt tension gauge to the belt with the
gauge face toward the engine, and measure the ten-
sion of the belt.
Remove the belt tension gauge carefully to avoid
hitting the gauge reset lever.
Tension:
Used Belt: 390 - 540 N {40 - 55 kgf, 88 - 121 lbf)
New Belt: 7,[0 - 840 N (75 - 90 kgf, 165 - 198 lbf)
CRANKSHAFT PULLEY
17-14
Measurement without Belt Tension Gauge:
Apply a force ot 98 N (10 kgf,22 lbt) and measure the
deflection between the power steering pump and the
crankshaft oullevs.
Deflection:
Used Belt: 11.0 - 1i1.5 mm {0.'(l - 0.57 in)
New Belt: 7.5 - 10.0 mm {0.30 - 0.39 in)
CRANKSHAFT PULLEY
Adiustment
'1. Loosen the power steering pump mounting bolt
and pump lock bolt.
PUMP MOUNNNG BOLT24 N'm (2.4 kgf'm, 17 lbf ftl
PUMP LOCK BOLT24 N.m 12.4 kgf.m, 17 lbf.ftl
Adjust the belt tension by moving the power steer-
ing pump with a 1/2" drive breaker bar to obtain theproper belt tension, then retighten the mounting
bolt and lock bolt.
Start the engine and turn the steering wheel from
lock-to-lock several times, then stop the engine and
recheck the deflection of the belt.
Measure here.
