REAR WHEEL ALIGNMENT CHECK AND ADJUSTMENT

1. Before the wheel alignment measurement, adjust the rear suspension, wheel, and tires in good condition.

2. Park the vehicle on a level surface to measure the wheel alignment.

TOE-IN

Standard value: 3 +- 2 mm (0.12 +- 0.08 inch)

If it is out of the standard range, adjust as follows: Turn the toe adjusting bolt (the mounting bolt inside the body on the control link) to adjust.

Left wheels: Clockwise → (+) Toe in
Right wheels: Clockwise → (-) Toe in

Toe-in varies approximately 2.6 mm (0.10inch) (equivalent to 0º16' of the toe angle for one side) for each scale mark.

CAMBER

Standard value: −0º25' +-0º30' (difference between right and left within 0º30')
