Information is not available from manufacturer.

Front Measurement

1. Lift up front end of vehicle under the control arms as close to the ball joints as possible. (Scheme 4) Check for play or looseness in the steering gear or tie rods, the wheel bearings, the upper spring strut mountings and control arm ball joints and bushings. If there is play in any of the above components, it must be corrected before an alignment can be performed.
2. Set up and calibrate test equipment according to manufacturer's instructions. Position the turntables under the front wheels. Use turntables which take up lateral movement. The car must stand level when the front wheels are on the turntables. Bounce the front suspension heavily a few times when the car has sunk onto the turntables.
3. Check the camber angle on both sides. Check measurement against specification. See «WHEEL ALIGNMENT SPECIFICATIONS»(ref-5259-S05996012822000081000000). The camber angle may vary by a maximum of 0.2°+/-.7° between the left and the right wheels. Adjust camber angle as needed. See «CAMBER ADJUSTMENT»(ref-5259-S34820535102000081000000).

Scheme 4

Rear Measurement

1. Check for play in the wheel bearings, the lateral link bushings and the control arm bushings. Set up and calibrate the test equipment being used. The car must be on a flat surface with the wheels on moveable plates.
2. Check camber angle. See «WHEEL ALIGNMENT SPECIFICATIONS»(ref-5259-S05996012822000081000000) . Check the control arms for damage if the camber angle is outside specification.

Check the caster angle on both sides. Check measurement against specification. See WHEEL ALIGNMENT SPECIFICATIONS . The caster angle must not vary by more than 1.0° between the left and right sides. Caster angle is not adjustable.

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. (Scheme 5) 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 .

Scheme 5

Check the toe-in. Check that the instruments are adjusted in relation to each other on the front and rear axles. See WHEEL ALIGNMENT SPECIFICATIONS . Adjust as needed. See TOE-IN ADJUSTMENT .
