STEERING COLUMN
1998 Mitsubishi Montero
1997-98 STEERING
Mitsubishi - Steering Columns - RWD & 4WD
Mitsubishi: Montero, Montero Sport
DESCRIPTION & OPERATION
WARNING: Vehicle is equipped with a Supplemental Restraint System
(SRS) that includes an air bag located in steering wheel.
Use caution when working around steering column. Ensure
battery is disconnected before attempting any repair. DO NOT
apply electrical power to any component on steering column
without disconnecting air bag module (air bag could deploy).
Steering column consists of a collapsible steering shaft with
lower joint assembly. Vehicle is equipped with a Supplemental
Restraint System (SRS) that includes an air bag and clockspring
located in steering column wheel.
NOTE: For information not covered in this article, air bag
DIAGNOSIS & TESTING or DISPOSAL PROCEDURES, see AIR BAG
RESTRAINT SYSTEM article.
DISABLING & ACTIVATING AIR BAG SYSTEM
WARNING: Wait at least 60 seconds after disconnecting negative
battery cable before servicing SRS. System reserve capacitor
maintains SRS voltage for about 60 seconds after battery is
disconnected. Servicing SRS before 60-second period may
cause accidental air bag deployment and possible personal
injury.
To disable system, turn ignition switch to OFF position.
Disconnect and isolate negative battery cable end. Wait at least 60
seconds. To activate system, reconnect negative battery cable.
AIR BAG SERVICE PRECAUTIONS
The following precautions should be observed when working
with SRS:
* Disable SRS before servicing any SRS or steering column
component. Failure to do this may result in accidental air
bag deployment and possible personal injury. See DISABLING &
ACTIVATING AIR BAG SYSTEM.
* Wait at least 60 SECONDS after disabling air bag system. SRS
system retains enough voltage, for a short time after system
is disabled, to deploy air bag.
* After repairs, always turn ignition on to ensure SRS warning
light is working properly and no system faults are indicated.
* Always wear safety glasses when servicing or handling an air
bag.
* DO NOT expose air bag module and clockspring to temperatures
more than 200
F (93C).
* When placing a live air bag on a bench or other surface,
always face air bag and trim cover up, away from surface.
This will reduce motion of module if air bag accidentally

STEERING SYSTEM - POWER RECIRCULATING BALL
1998 Mitsubishi Montero
1997-98 STEERING
Mitsubishi - Power Recirculating Ball
Montero, Montero Sport
DESCRIPTION & OPERATION
STEERING GEAR
The power steering gear displaces fluid to provide hydraulic
pressure assist while turning. A one-piece rack piston nut is geared
to cross shaft. Backlash is adjusted with an adjusting screw.
STEERING LINKAGE
Linkage consists of an idler arm, relay rod, steering
knuckles and adjustable tie rods. Components are connected by ball
joints. Linkage assembly is connected to steering gear by pitman arm.
LUBRICATION
FLUID TYPE
Recommended fluid type is Dexron-II ATF.
FLUID LEVEL CHECK
Place vehicle in level position. Start engine and let idle.
Turn steering wheel left and right. Replace fluid if it has bubbles or
has become White. Fluid level should be between MIN and MAX marks on
dipstick. Fill to proper level.
FLUID REPLACEMENT
CAUTION: DO NOT crank engine for more than 15-20 seconds at a time.
1) Remove reservoir cap. Disconnect return hose at reservoir.
Drain fluid. Disconnect coil high tension wire. Raise and support
vehicle.
2) Turn steering wheel lock-to-lock several times while
cranking engine to drain fluid from steering gear. Reconnect hose.
Fill power steering system with fluid. Bleed system. See
HYDRAULIC SYSTEM BLEEDING .
HYDRAULIC SYSTEM BLEEDING
CAUTION: DO NOT crank engine for more than 15-20 seconds at a time.
Add fluid as needed during procedure to prevent reservoir
level from dropping.
1) Ensure reservoir is filled before bleeding. Add fluid (if
necessary) during bleeding. Raise and support front of vehicle.
Disconnect coil high tension wire.
2) While cranking engine, turn steering wheel lock-to-lock 5
or 6 times. Lower vehicle. Connect coil wire. Start engine and let
idle. Turn steering wheel lock-to-lock until no more bubbles appear in
oil reservoir.

HYDRAULIC SYSTEM PRESSURE TEST
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), check
pressure. See POWER STEERING PUMP PRESSURE SPECIFICATIONS table.
Reinstall pressure hose. Do not twist hose or let hose interfere with
adjacent parts. Replace power steering pump 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.

P/S PRESSURE SWITCH

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-
