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,

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

VALVE HOUSING
Separate the valve housing from the pinion shafv
valve using a press.
Check the inner wall of the valve housing where the
seal ring slides with your finger. lf there is a step in
the wall, the valve housing is worn. Replace the
valve housing.
Note these items during inspection:
o There may be the sliding marks from the seal
ring on the wall of the valve housing. Replace
the valve housing only if the wall is stepped.
. When the valve housing is replaced, install new
shim{s) on the bearing surface of the housing to
adiust the thickness.
Check the inside ofvalve housingfor a step in the wall.
