Mexico models

Caster angle:
	Without 18 inch wheel:	5 ° 10 ’±30 ’
	With 18 inch wheel:	5 ° 6 ’±30 ’

If the measurement is within specifications, measure the front camber angle.

If the measurement is not within specifications, check for bent or damaged suspension components.

10.	Camber - Inspection
