*: Fuel, radiator coolantandengine oilfull. Spare tire,jack,
hand tools andmats indesignated positions.

SFA575B PRELIMINARY INSPECTION

1. Check tiresforwear andimproper inflation.
2. Check wheelrunout.

Wheel runout:
Refer toSOS (FA-30).

3. Check frontwheel bearings forlooseness.
4. Check frontsuspension forlooseness.
5. Check steering linkageforlooseness.
6. Check thatstruts workproperly.
7. Check vehicle posture (Unladen).

TOE-IN Measure toe-inusingfollowing procedure.
WARNING:
• Perform following procedure alwaysonaflat surface.
• Make surethatnoperson isin front ofthe vehicle before

the same height ashub center. Thesearemeasuring points.
4. Measure distance"A"(rear side).
5. Push thevehicle slowlyaheadtorotate thewheels 180
degrees (1/2turn).

If the wheels haverotated morethan180degrees
(112
turn), try
the above procedure againfromthebeginning. Neverpush
vehicle backward.

6. Measure distance"B"(front side).

Total toe-in
Refer toSOS (FA-29).
CAMBER,
CASTERANDKINGPIN INCLINATION
Camber, casterandkingpin inclination arepreset atfactory and
cannot beadjusted.

1. Measure camber,casterandkingpin inclination ofboth right
and leftwheels withasuitable alignment gauge.

Camber, CasterandKingpin inclination:
Refer toSOS (FA-29).

2. Ifcamber, casterorkingpin inclination isnot within
specification, inspectfrontsuspension parts.Replace dam-
