0A-20 GENERAL INFORMATION
In raising front or rear vehicle end off the floor by jacking, be sure
to put the jack against the center portion of the front suspension
frame or rear axle housing.
WARNING:

Never apply jack against suspension parts (i.e., stabilizer,
etc.) or vehicle floor, or it may get deformed.

If the vehicle to be jacked up only at the front or rear end,
be sure to block the wheels on ground in order to ensure
safety.
After the vehicle is jacked up, be sure to support it on
stands. It is extremely dangerous to do any work on the
vehicle raised on jack alone.
To perform service with either front or rear vehicle end jacked up,
be sure to place safety stands under chassis frame so that body is
securely supported. And then check to ensure that chassis frame
does not slide on safety stands and the vehicle is held stable for
safety's sake.

11) Check coil spring, upper rod, lower rod and lateral rod for de-
formation and damage.
12) Check upper rod, lower rod and lateral rod bushings and bump
stopper for wear, damage and deterioration.
13) Check other suspension parts for damage, loose or missing
parts; also for parts showing signs of wear or lack of lubrication.
Replace any parts found defective in steps 1) to 13).

1) Check universal joint and spline of propeller shaft for rattle. If
rattle is found, replace defective part with a new one.
2) Check propeller shaft (front & rear) flange yoke bolts for tight-
ness, and retighten them as necessary.
Refer to Section 4B for tightening torque.
3) Check drive axle boots (wheel side and differential side) for
leaks, detachment, tear or other damage.

Change
1) Inspect transmission case for evidence of fluid leakage.
Repair leaky point, if any.
2) Make sure that vehicle is placed level for fluid level check.
3) Change fluid. For its procedure, refer to On-vehicle service in
Section 7B1.
Fluid cooler hose change
Replace inlet and outlet hoses of cooler hose and their clamps.
For replacement procedure, refer to On-vehicle service in Section
7B1.

Transfer and Differential Oil Inspection and Change
Inspection
1) Check transfer case and differential for evidence of oil leakage.
Repair leaky point if any.
2) Make sure that vehicle is placed level for oil level check.
3) Remove level plug of transfer or differentials (front and rear) and
check oil level.
Oil level can be checked roughly by means of level plug hole.
That is, if oil flows out of level plug hole or if oil level is found up
to hole when level plug is removed, oil is properly filled.
If oil is found insufficient, pour specified amount of specified oil
referring to Section 7D, 7B or 7F.
4) Tighten level plug to specified torque.
Refer to Section 7D, 7E or 7F for tightening torque.
Change
Change transfer oil or differentials oil with new specified oil referring
to Section 7D, 7E and 7F respectively.

GENERAL DESCRIPTION
Rear suspension is 5 link type of rigid axle which consists of coil springs, rear axle, shock absorbers, upper rods,
lower rods and lateral rod.
The lower rod and upper rod are connected with the axle and body by using bushes so that axle moves up and
down with bushes as their supporting points.
The shock absorber is installed between the body and axle to absorb up-and-down movement of the vehicle body.
