Check frontaxleandfront suspension partsforexcessive play,
cracks, wearorother damage.
• Shake eachfrontwheel tocheck forexcessive play.
• Make surethatcotter pinsareinserted.
• Retighten allaxle andsuspension nutsandbolts tothe
specified torque.

Tightening torque:
Refer toFRONT SUSPENSION (FA-24).

•
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.

SFA484A Front
Wheel Bearing

• Check thatwheel bearings operatesmoothly.
• Check axialendplay.

Axial endplay: 0.05mm(0.0020 in)orless
• If
out ofspecification orwheel bearing doesnotturn
smoothly, replacewheelbearing assembly.
Refer toFRONT AXLE-Wheel HubandKnuckle (FA-B).

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:
• Perform following procedure alwaysonaflat surface.
• Make surethatnoperson isin front ofthe vehicle before
pushing it.

1. Bounce frontofvehicle upand down tostabilize theposture.
2. Push thevehicle straight aheadabout5m (16 ft).
3. Put amark onbase lineoftread (rearside) ofboth tires at
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-
aged orworn outparts.

1. Set wheels instraight-ahead position.Thenmove vehicle
forward untilfront wheels restonturning radiusgauge
properly.
2. Rotate steering wheelallthe way right andleft;measure
turning angle.

Do not hold thesteering wheelonfull lock formore than15
seconds.
