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

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.

Fluid Replacement
Check the reseryoir at regular intervals, and add the rec-
ommended fluid as necessary.
CAUTION: Always use Gsnuine Honda Power Steering
Fluid-V or S. Using any other type of power steering
tluid or automatic transmission fluid can cause increassd
wear and poor steering in cold w3athel.

1.Raise the reservoir. then disconnect the return hose
to drain the reservoir. Take care not to spill the fluid
on the body and parts. Wipe off any spilled fluid at
once.
2, Connect a hose of suitable diameter to the discon-
nected return hose, and put the hose end in a suit-
able container.
3. Stan the engine. let it run at idle, and turn the steer-
ing wheel from lock-to-lock several times. When
fluid stops running out of the hose, shut off the
engine. Discard the fluid.
4. Beinstallthe return hose on the reservoar.
5. Fill the reservoir to the upper level line,
6. Start the engine and run it at fast idle. then turn the
steering from lock-to-lock several times to bleed air
from the system.
7. Recheck the fluid level and add some if necessary.
Do not fill the reservoir beyond the upper level line.

8. Installation is the reverse ofthe removal procedure.
Note these items during installation:
. Be sure the wires are not caught or pinched by
any parts when installing the column.
a Make sure the wire harness is routed and fas-
tened properly.
. Make sure the connectors are properly connected.
. Make sure the steering joint is connected as fol-
lows:
a. lnsert the uDper end of the steering joint onto
the steering shaft (line up the bolt hole with
the flat ot the shaft).
b. Slip the lower end of the steering ioint onto
the Dinion shaft (lins up the bolt hole with the
groove around the shaft). and installthe lower
ioint bolt. Be sure that the lower joint bolt is
securely in the groove in the pinion shaft'
c. Pull on the steering joint to make sure that the
steering joint is JullY seated.
Then install the upper joint bolt and tighten it.

. 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.
1. Drain the power steering fluid as described on page'17-15.
Raise the vehicle, and suppon it on safety stands in
the proper locations (see section 1).

Install the 10 mm hex nut on the ball joint. Be sure
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.
Separate the tie-rod ball joint and knuckle using the
special tool.
Remove the right and left tie-rod ends, then extend
the rack all the way to the right.
Remove the TWC (see section 9).
