lPlug hose and pipe openings to prevent entry of dust or dirt.
lAlways replace O-ring and clamps with new ones.
lDo not kink or twist hose and tube when they are installed.
lDo not tighten hose clamps excessively to avoid damaging hoses.
lWhen installing fuel check valve, be careful of its designated direction. (Refer to ``EVAPORATIVE

CAUTION:
lAlways replace exhaust gaskets with new ones when
reassembling. If gasket is left on flange surface, scrape
off completely as shown at left.
lWith engine running, check all tube connections for
exhaust gas leaks, and entire system for unusual noises.
lEnsure that mounting brackets and mounting insulators
are installed properly and free from undue stress.
Improper installation could result in excessive noise or
vibration.
lDiscard any heated oxygen sensor which has been
dropped from a height of more than 0.5 m (19.7 in) onto
a hard surface such as concrete floor; use a new one.

lWhen installing rubber parts, final tightening must be
carried out under unladen condition* with tires on
ground.
* Fuel, radiator coolant and engine oil full. Spare tire,
jack, hand tools and mats in designated positions.
lUse flare nut wrench when removing or installing brake
tubes.
lAfter installing removed suspension parts, check wheel
alignment and adjust if necessary.
lAlways torque brake lines when installing.

PRECAUTIONS AND PREPARATION
FA-1

7. Turn wheel hub several times in both directions.
8. Retighten wheel bearing lock nut with Tool.
: 0.5 - 1.5 N´m (0.05 - 0.15 kg-m, 4.3 - 13.0 in-lb)
9. Measure wheel bearing axial end play.
Axial end play: 0 mm (0 in)
10. Measure starting force ``A'' at wheel hub bolt.
11. Install lock washer by tightening the lock nut within 15 to 30
degrees.
12. Turn wheel hub several times in both directions to seat wheel
bearing correctly.
13. Measure starting force ``B'' at wheel hub bolt. Refer to step
10.
14. Wheel bearing preload ``C'' can be calculated as shown
below.
C=BþA
Wheel bearing preload ``C'':
7.06 - 20.99 N (0.72 - 2.14 kg, 1.59 - 4.72 lb)
15. Repeat steps 3 through 14 until correct axial end play and
wheel bearing preload are obtained.
16. Install free-running hub.
Front Wheel Alignment
Before checking front wheel alignment, make a preliminary
inspection (Unladen*).
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
PRELIMINARY INSPECTION
1. Check tires for wear and proper inflation.
2. Check outside and inside wheel runout.
Wheel runout average
[(Outside runout value + Inside runout value) x 0.5]:
Refer to SDS, FA-35.
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
5. Check steering linkage for looseness.
6. Check that front shock absorbers work properly by using the
standard bounce test.

FRONT WHEEL TURNING ANGLE
1. Set wheels in straight-ahead position. Then move vehicle
forward until front wheels rest properly on turning radius
gauge.
2. Rotate steering wheel all the way right and left; measure
turning angle.
lOn power steering models, turn steering wheel to full lock
and apply force (at circumference of steering wheel) of 98 to
147 N (10 to 15 kg, 22 to 33 lb) with engine at idle.
lDo not hold the steering wheel at full lock for more than
15 seconds.
Wheel turning angle (Full turn):
Refer to SDS, FA-36.
3. Adjust stopper bolt if necessary.
