Rear Suspension
4. THRUST ANGLE
¼ 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:
Less than 30 ' when "L" is equal to or
less than 23 mm (0.91 in).
(1) Center line of loci (front axle)
(2) Center line of loci (rear axle)
¼ Adjustment
1) Make thrust angle adjustments by turning toe-in
adjusting bolts of rear suspension equally in the
same direction.
2) 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.

3) When left and right adjusting bolts are turned
incrementally by one graduation in the same
direction, the thrust angle will change approxi-
mately 10' ["L" is almost equal to 7.5 mm (0.295
in)].
Thrust angle:
0°±30 '
(1) Center line of loci (front axle)
(2) Center line of loci (rear axle)
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 direc-
tion depending on the degree of the mean thrust
angle.
