REAR AXLE -General Information27B-2
GENERAL INFORMATION
The rear axle consists of rear hubs, wheel bearings,
drive shafts, and rear differential and, it has the
following features.
DThe wheel bearing is a unit bearing (double-row
angular contact ball bearing).
DThe drive shaft incorporates B.J.-T.J. type
constant velocity joints with high transmission
efficiency and low vibration and noise.DABS rotors for detecting the wheel speeds are
press-fitted to the B.J. outer wheels in vehicles
with ABS or ACD.
NOTE
1. B.J.: Birfield Joint
2. T.J.: Tripod Joint

ON-VEHICLE SERVICE
REAR AXLE TOTAL BACKLASH CHECK
1. Park the vehicle on a flat, level surface.
2. Move the transmission control lever to the neutral position.
Apply the parking brake. Raise the vehicle on a jack.
3. Turn the companion flange clockwise as far as it will go.
Make the mating mark on the dust cover of the companion
flange and on the differential carrier.
4. Turn the companion flange anti-clockwise as far as it
will go, and measure the amount of distance the mating
marks moved.
Limit: 6 mm
5. If the backlash exceeds the limit value, replace the
differential carrier assembly.
GEAR OIL LEVEL CHECK

1. Remove the filler plug.
2. Check that the gear oil level is within the specified range
from the bottom end of the filler plug hole.
3. If the gear oil level exceeds the standard value, add the
specified gear oil up to the bottom end of the filler plug
hole.
Specified gear oil:
Hypoid gear oil
MITSUBISHI Genuine Gear Oil Part No. 8149630
EX, CASTROL HYPOY LS (GL-5, SAE 90),
SHELL-LSD (GL-5, SAE 80W - 90) or equivalent

REMOVAL SERVICE POINTS
AA"REAR BRAKE CALIPER REMOVAL
Suspend the rear brake caliper from the body with wire, etc.
to prevent it from falling.
Caution
If the vehicle is equipped with the Brembo disc brake, during
maintenance, take care not to contact the parts or tools to
the caliper because the paint of caliper will be scratched.
And if there is brake fluid on the caliper, wipe out quickly.
AB"DRIVE SHAFT NUT REMOVAL
Caution
Do not apply pressure to wheel bearing by the vehicle
weight to avoid possible damage to wheel bearing before
tightening drive shaft nut fully.
AC"REAR DRIVE SHAFT ASSEMBLY REMOVAL
1. Use the special tools to push out the drive shaft from
the hub.
2. Remove the drive shaft from the transmission by the
following procedure.
Insert a pry bar between the differential carrier and the
drive shaft, and then pry the drive shaft from the differential
carrier.
Caution
(1) Do not pull on the drive shaft; doing so will damage
the T.J.; be sure to use the pry bar.
(2) When pulling the drive shaft out from the
differential carrier, be careful that the spline part
of the drive shaft does not damage the oil seal.
(3) Do not apply the vehicle weight to the wheel
bearing while loosening the drive shaft nut.
Otherwise wheel bearing will be damaged. If,
however, the vehicle weight must be applied to
the bearing (because of moving the vehicle),
temporarily secure the wheel bearing by using
the special tool.

WARNING 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 driver and passenger (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

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 (*).

POWER PLANT MOUNT - General Information32-2
GENERAL INFORMATION
Inertia principal axes system is incorporated into
the engine mount system.Upper installation of roll mount reduces engine
rolling, and increase of insulator bore also reduces
idle vibration.

assembly.
INSPECTION
LOWER ARM BALL JOINT ROTATION STARTING
TORQUE CHECK
1. After shaking the ball joint stud several times, use the
special tool to measure the rotation starting torque of
the lower arm ball joint.
Standard value: 0.5 - 3.4 N·m
2. When the measured value exceeds the standard value,
replace the lower arm assembly.
3. When the measured value is lower than the standard
value, check that the lower arm ball joint turns smoothly
without excessive play. If there is no excessive play, the
ball joint can be reused.
PILLOW BALL BUSHING ROTATION STARTING
TORQUE CHECK
1. Insert the bolt to the lower arm pillow ball bushing, in
the opposite direction, insert the washer then install the
nut. After rotating the inner sleeve (contained washer)
several times, measure the rotation starting torque of
the lower arm pillow ball bushing using special tool.
Standard value: 0.5 - 3.0 N·m
2. When the measured value exceeds the standard value,
replace the pillow ball bushing.
3. When the measured value is lower than the standard
value, check that the lower arm pillow ball bushing turns
smoothly without excessive play. If there is no excessive
play, the pillow ball bushing can be reused.
LOWER ARM BALL JOINT DUST COVER CHECK
1. Check the dust cover for cracks or damage by pushing
it with finger.
2. If the dust cover is cracked or damaged, replace the
lower arm assembly.
NOTE
If the dust cover is cracked or damaged, it is possible
that there may also be damage to the ball joint.
When it is damaged during service work, replace the
dust cover.

then remove the crossmember mounting nuts and bolts.
2. Lower the crossmember until the fixture, the bushing and
the stabilizer bar can be removed.
Caution
Be careful not to lower the crossmember excessively,
otherwise the power steering return hose bracket may
deform.
