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.

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,

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.

5. Fully open the shut-off valve.
PRESSURECONTROL VALVE
6. Fully open the pressure controlvatve.
7. Start the engine and let it idle.
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.

lf the pump is in good condition, the gauge shouldread at least 6,900 - 7,800 kpa (70 - 80 kgflcmr,'1,000 - 1.140 psi). A low reading means pump out-put is too low for full assist. Repair or replace theDUMD.

Power Steering Gearbox
Removal
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.
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).
Remove the front wheels,
Remove the drive/s airbag assembly {see section 24).
Remove the steering wheel {see page 17-18).
Remove the steering joint bolts, then disconnect the
steering joint by moving the joint toward the column.

COTTER PINReplace.
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).
Disconnect the shift linkage from the transmission
(M/T: see section 13, A/T: see section 14).
With 4WD. separate the propeller shaft and transfer
assembly (see section 161.
