FRONT SUSPENSION ASSEMBLY
InspectionINFOID:0000000003811114
MOUNTING INSPECTION
Make sure the mounting conditions (looseness, backlash) of each component and component conditions
(wear, damage) are normal.
BALL JOINT AXIAL END PLAY
1. Set front wheels in a straight-ahead position.
CAUTION:
Never depress brake pedal when measuring.
2. Place an iron bar or equivalent between transverse link and steering knuckle.
3. Measure axial end play by prying it up and down.
CAUTION:
Be careful not to damage ball joint boot. Never damage the installation position by applying exces-
sive force.
STRUT ASSEMBLY
Check for oil leakage and damage. Replace if necessary.Standard
Axial end play : Refer to FSU-18, "
Ball Joint".

WHEEL ALIGNMENT
 Kingpin inclination angle is reference value, no inspection is required.
Toe-In
Measure toe-in by the following procedure.
WARNING:
 Always perform the following procedure on a flat surface.
 Make sure that no person is in front of vehicle before pushing it.
1. Bounce front of vehicle up and down to stabilize the vehicle height (posture).
2. Push vehicle straight ahead about 5 m (16 ft).
3. Put matching mark (A) on base line of the tread (rear side) of
both tires at the same height of hub center. These are measur-
ing points.
4. Measure distance (A) (rear side).
5. Push vehicle slowly ahead to rotate wheels 180 degrees (1/2
turn).
NOTE:
If the wheels rotates more than 180 degrees (1/2 turn), start this
procedure again from the beginning. Do not push the vehicle
backward.
6. Measure distance (B) (front side).
 If toe-in exceeds the standard value, adjust toe-in by varying the length of between steering outer socket
and inner socket.
