2. Wheel installation involves four factors:
collapse- the angle at which the front wheels are deviated from the vertical, when viewed from the front of the car. «Positive camber» magnitude (in degrees) on which the wheels are tilted from the vertical outward from above.
Longitudinal inclination of the kingpin is the angle between the kingpin axis and the vertical line, as viewed from each side of the vehicle. «Positive caster» the angle when the kingpin axis is tilted back.
Pivot tilt - corner (when viewed from the front of the car) between the vertical and an imaginary line drawn through the upper mounting of the suspension strut and the lower ball joint of the suspension arm.
Toe setting - the amount by which the distance between the front inner faces of the wheels differs (measured at hub height) from the diametrically opposite distance measured between the rear of the inner edges of the front wheels.
3. Kingpin pitch and kingpin axis tilt are determined during manufacture and cannot be changed.
4. Camber is adjusted by loosening the three top suspension strut nuts and moving the strut within the elongated holes in the mounting plate.
5. There are two methods available to the home mechanic to control the toe setting. One method is to use a gauge to measure the distance between the front and rear inner edges of the wheels. Another method is to use a moving plate, in which each front wheel is rolled across a plate that captures any deflection. Relatively inexpensive equipment of both types will allow you to check and then adjust the convergence.
6. If necessary, adjust as follows.
7. Loosen two nuts on each tie rod, turn adjusters as needed to complete installation (photo). Turn both knobs evenly, a quarter of a turn each time, check the setting. Lock the clips after installation.
