REAR AXLE ± General Information27-2
GENERAL INFORMATION27100010118

The rear axle is a banjo-type semi-floating type.
The axle shaft bearings are: *Single taper
bearings for vehicles without ABS or rear
differential lock. *Double-taper bearings for
vehicles with ABS or rear differential lock. ABS
rotor is press-fitted to the axle shaft retainer
ring.
Differential gear has 4 different types. A
torque-responsive mechanical-type limited slip
differential has a high performance against
driving on unstable surfaces such as muddy
roads.

Driveability on sand or muddy road has been
improved, and rear differential lock, which is
useful for emergency , has been used.

WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING!
(1) Improper service or maintenance of any component of the SRS, or any SRS-related component, can lead to personal
injury or death to service personnel (from inadvertent firing of the air bag) or to the driver (from rendering the SRS
inoperative).
(2) Service or maintenance of any SRS component or SRS-related component must be performed only at an authorized
MITSUBISHI dealer.
(3) MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B ± Supplemental
Restraint System (SRS) before beginning any service or maintenance of any component of the SRS or any SRS-related
component.
NOTE
The SRS includes the following components: impact sensors, SRS diagnosis unit, SRS warning lamp, air bag module, clock spring
and interconnecting wiring. Other SRS-related components (that may have to be removed/installed in connection with SRS service
or maintenance) are indicated in the table of contents by an asterisk (*).

1. Change to a different station with
a strong signal to boost resistance

Find out the following information from
the user:
1. Place
2. Locality conditions (valley, moun-
tain, etc.)
3. Name and frequency of stations
affected by noiseNo
If due to vehicle noise:
It may not be possible to prevent noise
if the signal is weak.
If there is more noise than other radios, find out the noise
conditions and the name and frequency of the receiving
stations from the user, and consult with the service centre.
If due to external noise:
In almost all cases, prevention on the
receiver side is impossible. Weak sig-
nals especially are susceptible to inter-
ference.

± General Information HEATER, AIR CONDITIONER
AND VENTILATION55-3
GENERAL INFORMATION55200010121
The heater system uses a two-way-flow full-air-mix
system that features high performance and low
operating noise, and includes an independent face
air blowing function and a cool air bypass function.The A/C system is basically the same as the
conventional system, but a new refrigerant system
has been adopted as a response to restrictions
on the use of chlorofluorocarbons.

Refrigerant and quantity gR-134a (HFC-134a), Approx. 550 ± 600
SAFETY PRECAUTIONS
Because R-134a refrigerant is a hydrofluorocarbon
(HFC) which contains hydrogen atoms in place of
chlorine atoms, it will not cause damage to the
ozone layer.
Refrigerant R-134a is transparent and colourless
in both the liquid and vapour state. Since it has
a boiling point of ± 29.8
C, at atmospheric pressure,
it will be a vapour at all normal temperatures and
pressures. The vapour is heavier than air,
non-flammable, and nonexplosive. The following
precautions must be observed when handling
R-134a.Caution
Wear safety goggles when servicing the
refrigeration system.
R-134a evaporates so rapidly at normal
atmospheric pressures and temperatures that it
tends to freeze anything it contacts. For this reason,
extreme care must be taken to prevent any liquid
refrigerant from contacting the skin and especially
the eyes. Always wear safety goggles when
servicing the refrigeration part of the A/C system.
Keep a bottle of sterile mineral oil handy when
working on the refrigeration system. Should any
liquid refrigerant get into the eyes, use a few drops
of mineral oil to wash them out. R-134a is rapidly
absorbed by the oil. Next splash the eyes with
plenty of cold water. Call your doctor immediately
even though irritation has ceased after treatment.

REFRIGERANT LEAK REPAIR55200150083
LOST CHARGE
If the system has lost all charge due to a leak:
1. Evacuate the system. (See procedure.)
2. Charge the system with approximately one
pound of refrigerant.
3. Check for leaks.
4. Discharge the system.
5. Repair leaks.
6. Replace receiver drier.
Caution
Replacement filter-drier units must be
sealed while in storage. The drier used in
these units will saturate water quickly upon
exposure to the atmosphere. When
installing a drier, have all tools and supplies
ready for quick reassembly to avoid keeping
the system open any longer than necessary.
7. Evacuate and charge system.
LOW CHARGE
If the system has not lost all of its refrigerant charge;
locate and repair all leaks. If it is necessary to
increase the system pressure to find the leak
(because of an especially low charge) add
refrigerant. If it is possible to repair the leak without
discharging the refrigerant system, use the
procedure for correcting low refrigerant level.HANDLING TUBING AND FITTINGS
Kinks in the refrigerant tubing or sharp bends in
the refrigerant hose lines will greatly reduce the
capacity of the entire system. High pressures are
produced in the system when it is operating.
Extreme care must be exercised to make sure that
all connections are pressure tight. Dirt and moisture
can enter the system when it is opened for repair
or replacement of lines or components. The
following precautions must be observed. The
system must be completely discharged before
opening any fitting of connection in the refrigeration
system. Open fittings with caution even after the
system has been discharged. If any pressure is
noticed as a fitting is loosened, allow trapped
pressure to bleed off very slowly.
Never attempt to rebend formed lines to fit. Use
the correct line for the installation you are servicing.
A good rule for the flexible hose lines is keep the
radius of all bends at least 10 times the diameter
of the hose.
Sharper bends will reduce the flow of refrigerant.
The flexible hose lines should be routed so that
they are at least 80 mm from the exhaust manifold.
It is good practice to inspect all flexible hose lines
at least once a year to make sure they are in good
condition and properly routed.
Unified plumbing connections with O-rings, these
O-rings are not reusable.
