3) Tighten a new self-locking nut.
Tightening torque:
100 Nm (10.2 kgf-m, 74 ft. lbs.)
THRUST ANGLE
^
Inspection
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 loci of both front and rear axles.
4) Measure the distance "L" between center lines of loci of the axles.
Thrust angle:
0°±30'(tolerance)
Less than 30' when "L" is less than 22 mm (0. 9 inch).

Adjustment
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
approximately 16' ["L" is almost equal to 12 mm (0.472 inch)].
