• INSPECTION
1) Park the vehicle on a level surface.
2) Move the vehicle 3 to 4 meters (10 to 13 feet) di-
rectly forward.
3) Draw the center of loci of both the front and rear
axles.
4) Measure the distance "L" between center lines of
the loci of axles.
Thrust angle:

(2) Center line of loci (rear axle)
• ADJUSTMENT
When adjusting, adjust it to the following value.
Thrust angle:

Less than 20
when "L" is 15 mm (0.6 in) or
less.
1) Make the thrust angle adjustments by turning the
toe-in adjusting bolts of rear suspension equally in
the same direction.

2) When one rear wheel is adjusted in a toe-in di-
rection, adjust the other rear wheel equally in toe-
out direction, in order to make the thrust angle ad-
justment.
3) When the left and right adjusting bolts are turned
by one graduation, the thrust angle will change ap-
prox. 17' ("L" is approx. 13 mm (0.51 in)).
NOTE:
Thrust angle refers to a mean value of left and right
rear wheel toe angles in relation to the vehicle body
center line. Vehicle is driven straight in the thrust
angle direction while slanting in the oblique direc-
tion depending on the degree of the mean thrust
angle.
