Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Front Measurement
Check that the instruments are adjusted in relation to each other on the front and rear axles. Front wheel toe-in is adjusted in relation to the car's thrust line. Thrust line is the line created when the rear wheels toe-in angles are equally divided. See Fig 1 . The difference between the wheel symmetry line and the thrust line is called the thrust angle. This angle may deviate by a maximum of 15° from the symmetry line.
Center and lock steering wheel. Check the front wheel toe-in. Check measurement against specification. See WHEEL ALIGNMENT SPECIFICATIONS . Adjust as needed. See TOE-IN ADJUSTMENT .
