lnspection and Adjustment
Pump Pressure Gheck With T/N 07406 - 0010001
Check the fluid pressure as follows to determine whetherthe trouble is in the pump orgearbox.
1. Check the powsr steering fluid level (see page 17-15), and pump belt tension (see page 17-14).
2. Disconnect the pump outlet hose from the pump
outlet with care so as not to spill the pow€r steeringiluid on the frame and other pans. thon install theP/S joint adapter (pumpl on the pump outlet.

8. Turn the steering wheel from lock-to-lock severaltimes to warm the fluid to operating temperature.
9, Measure steady-state fluid pressure while the engineis idling. lf the pump is in good condition, the gauge
should read less than 1,500 kPa (15 kgf/cmr, 213 psi).
lf it reads high, check the outlet hose or valve bodvunit (see General Troubleshooting).
10. Close the pressure control valve, then close theshut-off valve gradually until the pressure gauge
nsedle is stable. Read the pressure.

Pump Pressure Check With T/N 07406 -
Check the fluid pressure as follows to determine whether
the trouble is in the pump or gearbox.
1. Check the power steering tluid level (see page 17-
151, and pump belt tension (see page 17-14).
2. Disconnect the pump outlet hose from the pump
outlet with care so as not to spill the power steering
fluid on the frame and other parts, then install the

Steering Wheel
Removal
SRS components are located in this area. Review the
SRS component locations, precautions, and procedures
in the SRS section (24) before performing repairs or ser-
vice.
1. Align the front wheels straight ahead. then remove
the driver's airbag assembly (see section 24) from
the steering wheel.
2. Disconnect the horn connector and cruise control
switch connectors.
CONTROLSWITCHES CONNECTOR
3. Loosen the steering wheel bolt, then install a steering
wheel puller on the steering wheel and remove it.
Note these items when removing the steering wheel:
. Do not tap on the steering wheel or the steering
column shaft when removing the steering wheel.
. lf you thread the puller bolts into the wheel hub
more than five threads, the bolts will hit the cable
reel and damage it. To prevent this, install a pair
of jam nuts five threads up on each puller bolt.

1. Before installing the steering wheel, make sure the
front wheels are aligned straight ahead, then center
the cable reel. Do this by first rotating the cable reel
clockwise until it stops. Then rotate it counterclock-
wise approximately two turns. The arrow mark on
the cable reel label should point straight up.

. The power steering components are made of aluminum, Avoid damaging the components during assembly.
. Clean the disassembled parts with a solvent, and dry them with compressed air. Do not dip the rubber parts in a sol-
vent.
. Always replace the O-rings and rubber seals with new ones before assembly.
. Apply recommended power steering fluid to the parts indicated in the assembly procedures.
. Do not allow dust, dirt, or other foreign materials to enter the power steering system.
. Replace the pump as an assemblyif the parts indicated with asterisk(*) areworn ordamaged.

5. Submerge the valve in a container of power steer-
ing fluid or solvent, and blow in the hose. lf air bub-
bles leak through the valve at less than 98 kPa
(1.0 kgflcm', 14.2 psi), repair it as follows ('97 model).
For'98 - 00 models, the flow control valve cannot
be disassembled; replace the pump as an assembly

The relief pressure is adjusted at the factory by
adding shims under the check ball seat lf you found
shims in your valve, be sure you reinstall as many
as you took out.
lf the flow control valve tests OK, reinstall it in the
pump. It the flow control valve still leaks air, replace
the pump as an assembly. The flow control valve is
not available separately.

Note these items during removal:
. Using solvent and a brush, wash any oil and dirt off
the valve body unit its lines, and the end if the gear-
box. Blow dry with compressed air.
. Be sure to remove the steering wheel before discon-
necting the steering joint. Damage to the cable reel
can occur.
. With 4WD. tilt the engine with a jack to expand the
clearance between the transfer assembly and rear
beam when removing the steering gearbox from the
rear oeam.
Do not remove the steering gearbox by removing the
transfer assembly from the transmission.

that the 10 mm hex nut is flush with the ball joint
pin end, or the threaded section of the ball joint pin
might be damaged by the special tool. Refer to sec-
tion 18 for ball joint remover usage instruction, Be
careful not to damaging the ball joint boot.
