Thrust Angle

When adjusting, adjust it to the following value.

Thrust angle: Adjustment value

0°±20'

Less than 20' when "L" is 15 mm (0.6 in) or less

Make thrust angle adjustments by turning the toe-in adjusting bolts of the rear suspension equally in the same direction.
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 the thrust angle adjustment.
When the left and right adjusting bolts are turned by one graduation, the thrust angle will change approx. 15'. ("L" is approx. 11 mm (0.43 in)).

NOTE: Thrust angle is a mean value of left and right 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 direction depending on the degree of the mean thrust angle.

Thrust angle

γ = (α - β)/2

α: Rear RH wheel toe-in angle

β: Rear LH wheel toe-in angle

Substitute only the positive toe-in values from each wheel into α and β in the calculation.
