Ball Joint Inspection
1. Firmly grasp the outer end of the suspension
lower arm and try to move it up and down,
watching and feeling for any movement. Free
movement will usually be accompanied by an
audible "click''. There should be no free
movement. 2. If there is any free movement install a new lower
arm.

alignment.

/ Rear Toe Adjustment (204-00 Suspension
System - General Information, General
Procedures).
Strut or Shock Absorber Inspection
NOTE: Inspect the struts or shock absorber for
signs of oil weepage or leaks. Make sure that the
oil is not from another source.
Weepage:
• deposits a thin film of oil on the strut and spring assembly or shock absorber.
• is normally noticed due to a collection of dust on the strut and spring assembly or shock
absorber.
• occurs during the normal running-in period of 4800 - 8050 km. After this period no new signs
of oil should be visible.
• does not require new struts or shock absorbers to be installed.
Leakage:
• covers the entire strut and spring assembly or shock absorber with oil.
• will drip oil onto the surrounding suspension components.
• requires new struts or shock absorbers to be installed.
Strut or Shock Absorber Testing
NOTE: Struts or shock absorbers must be tested
in the vertical position.
1. Remove both strut and spring assemblies or shock absorbers. The piston rods should extend.
• Disassemble the strut and spring assemblies.
REFER to: Front Strut and Spring Assembly
(204-01 Front Suspension, Removal and
Installation).
2. Compress the piston rods. Both piston rods should offer the same resistance when
compressing.
3. Compress and release the piston rods. The piston rods should extent equally. 4. Compress and pull the piston rod in the vertical
position. Feel if the resistance force at the point
of direction change-over is perceptible without
a lag. If a lag is perceptible it is an indication of
damper valve damage and new struts or shock
absorbers must be installed. REFER to:
Front Strut and Spring Assembly (204-01 Front
Suspension, Removal and Installation),
Spring (204-02 Rear Suspension, Removal and
Installation).
Load-Levelling Shock Absorber
1. With the vehicle unladen, measure and note the dimensions between the base of the wheel rim
and the top of the rear fender on both sides.
• The measurements on both sides should be approximately equal.
2. With a load of 4 average size adults and a 100 kg weight, measure and note the dimensions
between the base of the wheel rim and the top
of the rear fender on both sides.
3. NOTE: Due to the internal ratchet mechanism of the suspension components, the height
of the rear of the vehicle should rise during
the road test.
With a load of 4 average size adults and a 100
kg weight, drive the vehicle for 3 km on a road
of normal condition.
4. With a load of 4 average size adults and a 100 kg weight, measure and note the dimensions
between the base of the wheel rim and the top
of the rear fender on both sides.
5. If the dimensions on both sides are no longer approximately equal, install new load levelling
shock absorbers.
REFER to: Spring(204-02 Rear Suspension,
Removal and Installation).
6. NOTE: Due to the internal ratchet mechanism of the suspension components, the height
of the rear of the vehicle should rise during
the road test.
If the dimensions are approximately equal,
unload the vehicle and drive the vehicle for 3
km on a road of normal condition.
7. With the vehicle unladen, measure and note the dimensions between the base of the wheel rim
and the top of the rear fender on both sides.
Check the final dimensions with the original
dimensions taken in the unladen condition.
