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.
<For reference>
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.
<For reference>
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.
