Component Tests

Raise and support the vehicle. REFER to:

Lifting

(100-02 Jacking and Lifting, Description

and Operation).

Ball Joint Inspection

1. 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. 2. If there is any free movement install a new lower arm.

REFER to:

Lower Arm

(204-01 Front Suspension, Removal and Installation).

3. 3. If a new lower arm is installed it will be necessary to check and adjust the front

wheel alignment.
REFER to:

Specifications

(204-00 Suspension System - General Information,

Specifications).

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. 1. Remove both strut and spring assemblies or shock absorbers. The piston rods

should extend.

Disassemble the strut and spring assemblies. REFER to:

Shock Absorber and

Spring Assembly

(204-01 Front Suspension, Disassembly and Assembly).

2. 2. Compress the piston rods. Both piston rods should offer the same resistance when

compressing.

3. 3. Compress and release the piston rods. The piston rods should extend equally.

4. 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 shock absorber valve damage and new struts or

operation.
