1) Disconnect pressure hose from power steering pump. Attach
Pressure Gauge (MB990662-01) and Adapters (MB990993-01 and MB990994-
01). See Fig. 2. Tighten fittings to 22-29 ft. lbs. (30-39 N.m).
2) Bleed system. See HYDRAULIC SYSTEM BLEEDING under
LUBRICATION . Turn wheel several times to bleed air from gauge. Start
engine and let idle. Place thermometer in reservoir. Check fluid
level. Add fluid as necessary.
3) When fluid temperature reaches 122-140
F (50-60C),
disconnect connector from P/S pressure switch. Connect ohmmeter across
switch terminals. Slowly close shut-off valve. Check pressure when
ohmmeter indicates switch has closed (continuity). Pressure should be
218-290 (15-20 N.m). Slowly open shut-off valve. Check pressure when
ohmmeter indicates switch has opened (no continuity). Pressure should
be 102-174 (7-12 N.m). Reinstall pressure hose. Do not twist hose or
let hose interfere with adjacent parts. Replace P/S pressure switch if
pressure is not within specification. Bleed system.
CAUTION: DO NOT keep shutoff valve closed more than 3 seconds at a
time. DO NOT keep steering wheel turned to full lock
position for more than 10 seconds at a time.
STEERING WHEEL TURNING FORCE
Stationary Test
1) Position vehicle on level surface. Place steering wheel in
straight-ahead position. Start engine and let idle. Using a spring
scale, measure steering wheel turning force clockwise and
counterclockwise.
2) On Montero, turning force should be 8.2 lbs. (3.7 kg) or
less. On Montero Sport, turning force should be 8.8 lbs. (3.9 kg) or
less. If turning force exceeds specification, check for loose or
damaged belt, insufficient fluid, air in power steering fluid, and
collapsed or twisted hoses. Repair or replace as necessary.
REMOVAL & INSTALLATION
IDLER ARM
Removal
Loosen relay rod-to-idler arm lock nut. Using Steering
Linkage Puller (MB991113 or MB990635), separate idler arm from relay
rod and remove relay rod-to-idler arm lock nut. Remove idler arm bolts
and nuts. Remove idler arm. On Montero, loosen, but DO NOT remove
idler arm-to-bracket nut. Press arm from bracket and remove nut and
arm.
Inspection
Check idler arm bushings for damage or wear. Check idler arm
ball stud for looseness.
Installation
1) Apply multipurpose grease to inside surface of bushing and
idler arm support shaft. Insert bushing in idler arm. Insert idler arm
support in idler arm.
2) Install washer (knurled side toward bushing) and NEW lock\
nut. Tighten lock nut to specification. See TORQUE SPECIFICATIONS.
Place idler arm assembly in vise. Using a spring gauge, measure
turning resistance.
3) On all models, turning resistance should be 3-18 INCH lbs.
(.3-2.0 N.m). On Montero, if turning resistance is not within
specification, loosen or tighten lock nut to obtain proper resistance.
4) Install idler arm bolts and nuts. Install relay rod-to-
end dust cover. Coat lower edge of cup with packing sealer. Install
tie rod ends into adjusting sleeves.
2) Measure center-to-center distance between tie rod studs
for both tie rod assemblies. Adjust center-to-center distance to
specification. See TIE ROD INSTALLATION LENGTH table.
3) An equal number of threads should be visible on each side
of adjusting sleeve. Install tie rod ends in steering knuckle and
relay rod. Install tie rod end castle nuts and NEW cotter pins.
Tighten castle nuts to specification. See TORQUE SPECIFICATIONS.
Adjust toe-in. See WHEEL ALIGNMENT SPECIFICATIONS & PROCEDURES article
in WHEEL ALIGNMENT section.

OVERHAUL
POWER STEERING GEAR
Disassembly
1) Scribe mating marks on pitman arm and cross shaft. Remove
pitman arm nut. Using a puller, remove pitman arm. Drain power
steering fluid. Remove side cover bolts. See Fig. 3. Loosen adjusting
bolt lock nut, and screw in adjusting bolt so side cover raises
slightly.
2) With mainshaft and cross shaft placed in straight-ahead
position, tap bottom of cross shaft with plastic hammer. Remove cross
shaft and side cover as an assembly. Remove side cover from cross
shaft by turning adjusting bolt.
3) Remove valve housing and rack piston as an assembly by
turning rack piston counterclockwise. See Fig. 3. Carefully remove
rack piston from mainshaft without losing balls inside rack piston.
4) Remove cross shaft oil seal from gearbox housing. Put rack
piston in soft jawed vise. Using Spanner Wrench (MB991367) and Pin Set\
(MB991394), remove lock nut. Remove mainshaft while applying pressure
to bearing race to prevent balls from falling out. Drive out bearing
and oil seal.
NOTE: DO NOT remove cross shaft "U" packing at rear of needle
bearing unless fluid leakage is found coming from adjusting
bolt threads. If leakage exists, replace "U" packing.
cross shaft and rack piston for wear and damage. Check contact part of
adjusting bolt for uneven wear. Check dust seal, oil seal and "O"
rings for wear and damage.
Reassembly
1) Install NEW cross shaft lower "U" packing (if removed).
Press lower cross shaft oil seal into gearbox housing. See Fig. 3.
Press bearing and oil seal into top cover. Install bearing race and
"O" ring.
2) Apply transmission fluid to seal ring contact areas on
mainshaft, and install seal rings firmly into valve grooves. Wrap
serrated part of mainshaft with vinyl tape. Mount valve body to valve
housing. Install cage and align hole in cage with channel in
mainshaft. Install bearing race and insert balls.
3) Install mainshaft into valve housing while pressing on
bearing race to prevent balls from falling out. Using spanner wrench,
install lock nut and tighten until it contacts bearing race.
4) Tighten lock nut while measuring mainshaft endplay using
dial indicator. When mainshaft endplay is .001" (.003 mm), use a punch\
to crimp circumference of lock nut. Ensure mainshaft rotates freely.
5) Apply transmission fluid to "O" ring and piston seal ring,
and install into gearbox housing. Install rack piston until it
contacts edge of mainshaft. Rotate mainshaft to align ball raceway
with insertion hole. Install 19 balls.
NOTE: Insert balls so no clearance exists between balls.
6) Place remaining 7 balls in circulator and install
circulator to rack piston. Install circulator holder. Install NEW
cross shaft upper "U" packing (if removed). Install upper cross shaft
"O" ring. Apply transmission fluid to rack piston seal ring and insert
valve housing. Rotate mainshaft until rack piston is centered (neutral
position).
7) Install adjusting plate so beveled part is facing upward.
Using a feeler gauge, measure clearance between adjusting bolt and
cross shaft. If clearance is greater than .002" (.05 mm), replace with\
appropriate adjusting plate.
8) Apply multipurpose grease to seal surface of "U" packing.
Apply transmission fluid to cross shaft teeth and side cover "O" ring.
Install cross shaft to side cover, and temporarily tighten adjusting
bolt lock nut.
CAUTION: DO NOT rotate side cover during installation, or damage to
cross shaft oil seal may result.
9) Apply transmission fluid to rack piston teeth and shaft
areas. Apply multipurpose grease to oil seal lip. Install side cover
assembly (with cross shaft) to gearbox.
10) Position mainshaft in straight-ahead position. While
turning adjusting bolt, measure mainshaft combined starting torque
using Preload Socket (MB990228-01) and an INCH-lb. torque wrench.
Combined starting torque should be 4-11 INCH lbs. (.5-1.3 N.m). Center\
reading should be 2 INCH lbs. (.2 N.m) higher than reading at either
end.
11) Tighten adjusting bolt lock nut to specification. See
TORQUE SPECIFICATIONS . Install pitman arm with mating marks aligned.
POWER STEERING PUMP
Disassembly
1) Remove suction connector bolts. Mount pump in a soft-jawed
vise. Remove pump cover bolts and cover. Using a plastic mallet, tap

SUN ROOF - POWER
1998 Mitsubishi Montero
1998 ACCESSORIES & EQUIPMENT
Mitsubishi - Power Sun Roofs
Eclipse, Galant, Montero, Montero Sport, 3000GT
DESCRIPTION & OPERATION
Sun roof is actuated by an overhead console-mounted switch.
Sun roof motor, located near switch, moves sun roof panel by means of
drive cables. If necessary, sun roof can be closed manually using
manual closure wrench stored in vehicle's tool pouch.
On vehicles equipped with Electronic Timer Alarm Control
System (ETACS) ECU, sun roof can be operated up to 30 seconds after
ignition switch is turned to OFF position.
Sun roof motor incorporates a safety feature that initially
limits opening or closing of roof glass panel. Sun roof will not fully
close from fully open position without first releasing and then
depressing slide switch during operation. Sun roof initially stops
about 8" short of fully closed position.
