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).

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).

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.

26. Check for wear, burrs and other damage to the
edges of the grooves in the sleeve.
NOTE: The pinion shaft and sleeve are a precision
matched set. lf either the oinion shaft or sleeve
must be replaced, replace both parts as a set.

damage the edges ot the sleeve grooves and outer
surface when removing the seal rings.
Using a cutter or an equivalent tool. cut the valve
seal ring and O-ring at the groove in the pinion
shaft. Remove the valve seal ring and O-ring. Be

Note these items during disassembly:
. Inspect the ball bearing by rotating the outer race
slowly. lf there is any excessive play, replace the
pinion shaft and sleeve as an assembly.
. The pinion shaft and sleeve are a precise fit; do
not intermix old and new Dinion shafts and
sreeves,

Apply power steering fluid to the surface of the spe-
cial tool. Set the new seal rings over the special tool
from the smaller diameter end of the tool. and
expand the seal rings. Install two rings at a time
Jrom each end ofthe sleeve.
Note these items when installing the seal ring:
. Do not over-expand the seal ring. Install the resin
seal rings with care so as not to damage them.
After installation, be sure to contract the seal
rings using the specialtool {sizing tool).
. There are two types of sleeve seal rings: black
and brown. Do not mix the different types of
sleeve seal rings as they are not compatible.
Align the special tool with each groove in the sleeve,
and slide a sleeve seal ring into each groove. After
installation, compress the seal rings with your fin-
gers temporarily.

by aligning the locating pin on the inside of the
sleeve with the cutout in the shaft. Then install the
new circlip securely in the pinion shaft groove.
Note these items during reassembly:
. Be caretul not to damage the valve seal ring
when inserting the sleeve.
. Install the circlip with its radiused side facing out.
Apply power steering fluid to the seal ring lip of the
valve oil seal. then install the seal in the valve hous-
ing using a hydraulic press and special tools. Install
