NOTE:

Front and rear toe-ins and front camber can be adjusted.
If toe-in or front camber tolerance exceeds specifications,
adjust toe-in and camber to the specification.

The other items indicated in the specification table can-
not be adjusted. If the other items exceeds specifications,
check suspension parts and joint portions of body suspen-
sion parts for deformities; and replace with new ones as
required.

6. THRUST ANGLE

Inspection
1) Position vehicle on a level surface.
2) Move vehicle 3 to 4 meters directly forward.
3) Determine locus of both front and rear axles.
4) Measure distance“L”between center line of loci of the
axles.

Thrust angle is less than 20’when“L”is equal to or less
than 15 mm (0.59 in).

Adjustment
Make thrust angle adjustments by turning toe-in adjusting
bolts of rear suspension equally in the same direction.
NOTE:
On FWD models, turn adjusting wheels one by one, by the
some amount in the opposite direction of the adjusting
bolts.

When one rear wheel is adjusted in a toe-in direction,
adjust the other rear wheel equally in toe-out direction, in
order to make thrust angle adjustment.
When left and right adjusting bolts are turned incremen-
tally by one graduation in the same direction, the thrust
angle of the AWD model will change approximately 10’[“L”
is almost equal to 7.5 mm (0.295 in)] and the thrust angle
of the FWD model will change approximately 12’[“L”is
almost equal to 9 mm (0.35 in)].
Thrust angle:
0°±20′
B4M0193A
NOTE:
Thrust angle refers to a mean value of left and right rear
wheel toe angles in relation to vehicle body center line.
Vehicle is driven straight in the thrust angle direction while
swinging in the oblique direction depending on the degree
of the mean thrust angle.
B4M0194A
Thrust angle: r
r=αβ2
α: Right rear wheel toe angle
β: Left rear wheel toe angle
NOTE:
Here, use only positive toe-in values from each wheel to
substitute forαandβin the equation.

4-1SERVICE PROCEDURE
1. On-car Services

1. Suspension
1. IMPROPER VEHICLE POSTURE OR IMPROPER
WHEEL ARCH HEIGHT
Possible causes Countermeasures
(1) Permanent distortion or breakage of coil spring Replace.
(2) Unsmooth operation of damper strut Replace.
(3) Installation of wrong strut Replace with proper parts.
(4) Installation of wrong coil spring Replace with proper parts.
2. POOR RIDE COMFORT
1) Large rebound shock
2) Rocking of vehicle continues too long after running over
bump and/or hump.
3) Large shock in bumping
Possible causes Countermeasures
(1) Breakage of coil spring Replace.
(2) Over-inflation pressure of tire Adjust.
(3) Improper wheel arch height Adjust or replace coil springs with new ones.
(4) Fault in operation of damper strut Replace.
(5) Damage or deformation of strut mount Replace.
(6) Unsuitability of maximum and/or minimum length of
damper strutReplace with proper parts.
(7) Deformation or loss of bushing Replace.
(8) Deformation or damage of helper in strut assembly Replace.
(9) Oil leakage of damper strut Replace.
3. NOISE
Possible causes Countermeasures
(1) Wear or damage of damper strut component parts Replace.
(2) Loosening of suspension link installing bolt and/or nut Retighten to the specified torque.
(3) Deformation or loss of bushing Replace.
(4) Unsuitability of maximum and/or minimum length of
damper strutReplace with proper parts.
(5) Breakage of coil spring Replace.
(6) Wear or damage of ball joint Replace.
(7) Deformation of stabilizer clamp Replace.

4-1DIAGNOSTICS
1. Suspension

Check tie-rod ends, tie-rods and ball
joints of suspension for unsteady
revolution or rattling.
GOOD
NOT GOOD
Inspect, replace if necessary.
Measure rotating and sliding resistance
of gearbox.
Result: Rotating resistance is 11.18 N
(1.14 kg, 2.51 lb) or less around
center position and 15.79 N
(1.61 kg, 3.55 lb) or less in all
positions within 20% difference
between clockwise and
counterclockwise.
Sliding resistance is 304 N (31
kg, 68 lb) or less with 20%
difference between left and right
directions.NOT GOOD
Readjust backlash, if ineffective replace
bad parts.

6. NOISE AND VIBRATION
*6
Hiss noise (continu-
ous)
While engine is run-
ning with maximum
turning angle.
Relief valve soundGenerates at max.
turning angle.Normal (Don’t keep
this condition over 5
seconds.)
Generates without
steering operation.Defective
Replace oil pump.
Rattling noise
(intermittent)
While engine is run-
ning.Interference with adjacent partsCheck clearance.
[Refer to next article
6.]
Correct if necessary.
Loosened installation of oil pump, oil tank, pump bracket,
gearbox or crossmember.Retighten.
Loosened installation of oil pump pulley or other pulley(s).Retighten.
Loosened linkage or play of steering or suspension.
Loosened tightening of joint or steering column.Retighten or replace.
Sound generates from the inside of gearbox or oil pump.Replace the gearbox
or oil pump.
Knocking
When turning steer-
ing wheel in both
direction with small
angle repeatedly at
engine ON or OFF.Excessive backlash
Loosened lock nut for adjusting backlash.Adjust and retighten.
Loosened tightening or play of tie-rod, tie-rod end.Retighten or replace.
*6 Don’t keep the relief valve operated over 5 sec. at any time or inner parts of the oil pump may be damaged due to rapid increase
of fluid temperature.
