Check strut(shock absorber) foroilleakage orother dam-
age.
• Check suspension balljoint forgrease leakage andball
joint dustcover forcracks orother damage.
If ball joint dustcover iscracked ordamaged, replacetrans-
verse link.
• Check suspension balljoint endplay.
a. Jack upfront ofvehicle andsetthe stands.
b. Clamp dialindicator ontotransverse linkand place indica- •
tor tiponlower edgeofbrake caliper. •
c. Make surefront wheels arestraight andbrake pedalis
depressed.
d. Place apry bar between transverse linkand inner rimof
road wheel.
e. While raising andreleasing prybar, observe maximum dial
indicator value.
Vertical endplay: 0mm (0in)

f. Ifball joint vertical endplay exists, remove transverse link
and recheck theball joint. Refer toFA-27.

Wheel Bearing

• Check thatwheel bearings operatesmoothly.
• Check axialendplay.

Axial endplay: 0.05mm(0.0020 in)orless
• If

Front Wheel Alignment

Before checking frontwheel alignment, besure tomake apre-
liminary inspection (Unladen*).
*: 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:

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-
aged orworn outparts.
