ing the alignment:
Check that the suspension is not modified.
Check the tire size and tire pressure.
Check the runout of the wheels and tires.
Check the suspension ball joints. (Hold a wheel with
your hands, and move it up and down and right and

(caster, camber, toe, and/or turning angle). Follow the
equipment manufacturer's instructions.

2. Check the caster angle.
Caster angle: 2°50'±1°
3. If out of specification, check for damaged suspen-
