lCheck suspension ball joint end play.
a. Jack up front of vehicle and set the stands.
b. Clamp dial indicator onto transverse link and place indicator
tip on lower edge of brake caliper.
c. Make sure front wheels are straight and brake pedal is
depressed.
d. Place a pry bar between transverse link and inner rim of road
wheel.
e. While raising and releasing pry bar, observe maximum dial
indicator value.
Vertical end play:
0mm(0in)
f. If ball joint vertical end play exists, remove transverse link
and recheck the ball joint. Refer to ªFRONT SUSPENSIONº,
FA-32.
Front Wheel Bearing
lCheck that wheel bearings operate smoothly.
lCheck axial end play.
Axial end play:
0.05 mm (0.0020 in) or less
lIf axial end play is not within specification or wheel bearing
does not turn smoothly, replace wheel bearing assembly.
Refer to ªWheel Hub and Knuckleº, ªFRONT AXLEº, FA-FA-
11 .
Front Wheel Alignment
Before checking front wheel alignment, be sure to make a pre-
liminary 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 improper inflation.
2. Check wheels for deformation, cracks and other damage. If
deformed, remove tire and check wheel runout.
Wheel runout:
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 correctly by using the
standard bounce test.
7. Check vehicle posture (Unladen).

Rear Wheel Alignment
PRELIMINARY INSPECTION
Make following checks. Adjust, repair or replace if necessary.
lCheck tires for wear and for improper inflation.
lCheck rear wheel bearings for excessive play.
lCheck wheels for deformation, cracks and other damage. If
deformed, remove tire and check wheel runout.
Wheel runout: Refer to SDS in FA section.
lCheck that rear shock absorber functions correctly.
lCheck rear axle and rear suspension parts for excessive
play.
lCheck vehicle posture (Unladen*).
*: Fuel, radiator and engine oil full. Spare tire, jack, hand
tools and mats in designated positions.
CAMBER
Camber is preset at factory and cannot be adjusted.
Camber:
Refer to SDS (RA-14).
lIf the camber is not within specification, inspect and replace
any damaged or worn rear suspension parts.
TOE-IN
Toe-in is preset at factory and cannot be adjusted.
Measure toe-in using following procedure. If out of
specification, inspect and replace any damaged or worn rear
suspension parts.
WARNING:
lAlways perform following procedure on a flat surface.
lMake sure that no person is in front of the vehicle before
pushing it.
1. Bounce rear of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of both tires
at the same height of hub center. This mark is a measuring
point.
4. Measure distance ªAº (rear side).
5. Push the vehicle slowly ahead to rotate the wheels 180
degrees (1/2 turn).
If the wheels have rotated more than 180 degrees (1/2 turn),
try the above procedure again from the beginning. Never
push vehicle backward.
6. Measure distance ªBº (front side).
Total toe-in:
Refer to SDS, RA-14.

lIncomplete air bleeding will cause the following to occur.
When this happens, bleed air again.
a. Generation of air bubbles in reservoir tank
b. Generation of clicking noise in oil pump
c. Excessive buzzing in oil pump
While the vehicle is stationary or while moving the steering wheel
slowly, fluid noise may occur in the valve or oil pump. This noise
is inherent in this steering system, and it will not affect perfor-
mance or durability of the system.
Checking Steering Wheel Turning Force
1. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating tempera-
ture. [Make sure temperature of fluid is approximately 60 to
80ÉC (140 to 176ÉF).]
Tires need to be inflated to normal pressure.
4. Check steering wheel turning force when steering wheel has
been turned 360É from neutral position.
Steering wheel turning force:
44.1 N (4.5 kg, 9.9 lb) or less
5. If steering wheel turning force is out of specification, check
rack sliding force to detect condition of steering gear assem-
bly.
a. Disconnect steering column lower joint and knuckle arms
from the gear.
b. Start and run engine at idle to make sure steering fluid has
reached normal operating temperature.
c. While pulling tie-rod slowly from the neutral position, make
sure rack sliding force is within specification.
Rack sliding force:
284 N (29 kg, 64 lb) or less
6. If rack sliding force is not within specification, replace steer-
ing gear assembly.
