Thrust Angle

1. Position the vehicle on a level surface.
2. Move the vehicle 3 to 4 m (10 to 13 ft) directly forward.
3. Determine the center lines of front axle loci and rear axle loci.
4. Measure the distance "L" between center line of loci of the axles.

   Thrust angle: 

   Permissible value: 

   0°++/-30'(Less than 30' when "L" is less than 23 mm (0.9 in).)

Adjust to specified value at adjustment, if it exceeds the permissible value.

Thrust angle: 

Specified value at adjustment: 

0°++/-20' (Less than 20' when "L" is less than 15 mm (0.6 in).) 

1. Make the 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 the right and left adjusting bolts are turned incrementally by one graduation in the same direction, the thrust angle will change approx. 16' ["L" is almost equal to 12 mm (0.472 in)].

   NOTE: Thrust angle means the average of left and right wheel toe angle to body center line. Vehicle goes straight to the direction of thrust angle while rolling obliquely.

   Thrust angle: "GAMMA"=("ALPHA" - "BETA")/2 

   "ALPHA": Right rear wheel toe-in angle

   "BETA": Left rear wheel toe-in angle Here, use only positive toe-in values from each wheel to substitute for "ALPHA" and "BETA" in the equation.
