1991 DRIVE AXLES
Locking Hubs
Mitsubishi: Montero, Pickup
DESCRIPTION
Automatic hubs are engaged by rotational force of axle shaft
when 4WD is selected at transfer case. Automatic hubs disengage when
2WD is selected or vehicle is driven in Reverse. Cams, brakes and
springs are used to lock or unlock automatic hubs.
Engagement is accomplished through gears and spring actions
within hub. When hub is locked, hub brake engages inner hub, which is
connected to axle shaft by inner splines of hub. Hub brake is
connected to hub body by outer splines.
REMOVAL
1) Hub must be unlocked. To unlock hub, place transfer case
lever in 2H position and move vehicle in Reverse approximately 4-6
feet.
2) Remove cover from locking hub. If hub cover cannot be
loosened by hand, wrap shop towel around cover and use an oil filter
wrench to loosen cover.
3) Raise and support vehicle. Remove wheel assembly. Using
snap ring pliers, remove snap ring and shim from end of axle. Remove
locking hub retaining bolts. Remove locking hub.
INSTALLATION
1) To install, reverse removal procedure. Apply sealant to
contact areas between locking hub assembly and hub/rotor assembly.
Ensure sealant is NOT applied on outer areas of hub/rotor assembly
toward brake contact areas.
2) Align locking hub assembly key area with steering knuckle
key way area. Loosely install locking hub assembly on hub/rotor
assembly. Ensure locking hub assembly fully contacts hub/rotor
assembly.
3) Install locking hub retaining bolts. Tighten bolts to 36-
43 ft. lbs. (49-58 N.m). Using spring scale attached to wheel stud,
measure turning resistance required to rotate hub/rotor assembly.
4) Turning resistance should NOT exceed 3.1 lbs. (1.4 kg). I\
f
turning resistance exceeds specification, check for incorrect
installation of locking hub assembly or components.
5) Install shim and snap ring on drive axle. Rotate drive
axle until maximum end play is obtained. Using a dial indicator, check
drive axle end play.
6) Drive axle end play should be .008-.020" (.20-.51 mm). If\
axle end play is NOT within specification, adjust end play by changing
axle shaft shim. Install hub cover. Tighten hub cover 13-25 ft. lbs.
(18-34 N.m).

WHEEL & TIRE SPECIFICATIONS
Tire specifications are imprinted on the tire side wall. The
recommended cold tire inflation pressures are listed on a label
attached to the rear face of the driver's door. These pressures
provide the best combination of ride comfort, tire wear and stability
under normal conditions.
CAUTION: DO NOT mix tires of different design such as radial ply
with bias or bias-belted tires. Mixing tire types will
adversely affect road handling and may lead to loss of
vehicle control. When using snow tires, they must be used
in set of four for maneuverability and safety. DO NOT use
tire chains on front wheels.

CAUTIONS & WARNINGS
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) AIR BAG SYSTEM
NOTE: See the AIR BAG RESTRAINT SYSTEM article in the
ACCESSORIES/SAFETY EQUIPMENT Section.
The SRS has no user-servicable parts. Always have servicing
done by an authorized dealer.
When performing maintenance on air bag equipped vehicles
always observe proper safety precautions.
WARNING: To avoid injury from accidental air bag deployment, read and
carefully follow all warnings and service precautions. See
appropriate AIR BAG RESTRAINT SYSTEM article in the
ACCESSORIES/SAFETY EQUIPMENT section.
CAUTION: Disconnect negative battery cable before servicing any air
bag system, steering column or passenger side dash
component. After any repair, turn ignition key to the ON
position from passenger's side of vehicle in case of
accidental air bag inflation
ANTI-LOCK BRAKE SYSTEM (ABS)
CAUTION: Never mix different diameter tires. On loose or uneven
surfaces, the ABS system may require longer stopping
distances than conventional brake systems. Exercise caution
when removing mud or snow from the wheels so as not to
damage the ABS wiring or speed sensors.
BATTERY WARNING
WARNING: When battery is disconnected, vehicles equipped with
computers may lose memory data. When battery power is
restored, driveability problems may exist on some vehicles.
These vehicles may require a relearn procedure. See
appropriate COMPUTER RELEARN PROCEDURES article in the
GENERAL INFORMATION section below.
REPLACING BLOWN FUSES
Before replacing a blown fuse, remove ignition key, turn off
all lights and accessories to avoid damaging the electrical system. Be
sure to use fuse with the correct indicated amperage rating. The use
of an incorrect amperage rating fuse may result in a dangerous
electrical system overload.
BRAKE PAD WEAR INDICATOR
Indicator will cause a squealing or scraping noise, warning
that brake pads need replacement.

Wheel Alignment
PRE-ALIGNMENT INSPECTION PROCEDURES
PRE-ALIGNMENT CHECKS
Before making wheel alignment adjustment, perform the
following checks:
1) Tires should be equal in size and runout must not be
excessive. Tires and wheels should be in balance, and inflated to
manufacturer's specifications.
2) Wheel bearings must be properly adjusted. Steering linkage
and suspension must not have excessive looseness. Check for wear in
tie rod ends and ball joints.
3) Steering gear box must not have excessive play. Check and
adjust to manufacturer's specifications.
4) Vehicle must be at curb height with full fuel load and
spare tire in vehicle. No extra load should be on vehicle.
5) Vehicle must be level with floor and with suspension
settled. Jounce front and rear of vehicle several times and allow it
to settle to normal curb height.
6) If steering wheel is not centered with front wheels in
straight-ahead position, correct by shortening one tie rod adjusting
sleeve and lengthening opposite sleeve equal amounts.
7) Ensure wheel lug nuts are tightened to torque
specifications.

* PLEASE READ THIS FIRST *
NOTE: All SERVICE SCHEDULES are listed for normal service
vehicles. If vehicle is operated under severe service
conditions, see
SEVERE SERVICE REQUIREMENTS (PERFORM W/SERVICE SCHEDULES)
for items requiring additional maintenance.
NOTE: This article contains scheduled maintenance service
information. Fluid types and capacities listed with each
service in this article are only those necessary to perform
that scheduled service. For specifications pertaining to
fluid capacities for the entire vehicle, fuse and circuit

MAINTENANCE INFORMATION article in this section.
CAUTIONS & WARNINGS
SUPPLEMENTAL RESTRAINT SYSTEM (AIR BAG)
NOTE: See the AIR BAG RESTRAINT SYSTEM article in the
ACCESSORIES/SAFETY EQUIPMENT Section.
Modifications or improper maintenance, including incorrect
removal and installation of the Supplemental Restraint System (SRS),
can adversely affect system performance. DO NOT cover, obstruct or
change the steering wheel horn pad in any way, as such action could
cause improper function of the system. Use only plain water when
cleaning the horn pad. Solvents or cleaners could adversely affect the
air bag cover and cause improper deployment of the system.
WARNING: To avoid injury from accidental air bag deployment, read and
carefully follow all warnings and service precautions. See
appropriate AIR BAG RESTRAINT SYSTEM article in the
ACCESSORIES/SAFETY EQUIPMENT section.
CAUTION: Disconnect negative battery cable before servicing any air
bag system, steering column or passenger side dash
component. After any repair, turn ignition key to the ON
position from passenger's side of vehicle in case of
accidental air bag inflation
AIR CONDITIONING SERVICING
WARNING: R-134a service equipment or vehicle A/C systems SHOULD NOT
be pressure tested or leak tested with compressed air. Some
mixtures of air/R134a have shown to be combustible at
elevated pressures. These mixtures are dangerous and may
cause fire and/or explosions. See the appropriate
A/C SYSTEM GENERAL SERVICING article in the AIR CONDITIONING
& HEAT section.

touching a metal ground point on the vehicle prior to
servicing any ESD sensitive component.
ENGINE OIL
CAUTION: Never use non-detergent or straight mineral oil.
FUEL SYSTEM SERVICE
WARNING: Relieve fuel system pressure prior to servicing any fuel
system component (fuel injection models).
HALOGEN BULBS
Halogen bulbs contain pressurized gas which may explode if
overheated. DO NOT touch glass portion of bulb with bare hands. Eye
protection should be worn when handling or working around halogen
bulbs.
POWER STEERING FLUID
When adding power steering fluid, avoid spilling. Damage to
alternator, located beneath power steering reservoir, could result.
RADIATOR CAP
CAUTION: Always disconnect the fan motor when working near the
radiator fan. The fan is temperature controlled and could
start at any time even when the ignition key is in the OFF
position. DO NOT loosen or remove radiator cap when cooling
system is hot.
RADIATOR FAN
WARNING: Keep hands away from radiator fan. Fan is controlled by a
thermostatic switch which may come on or run for up to 15
minutes even after engine is turned off.
