There are two dimensions to the rear wheel alignment:
- convergence angle;
- collapse angle.
Of these two values, only the toe angle is subject to adjustment.
Adjustment of convergence is carried out by rotating the eccentric bolt (1) fixing the internal silent block for attaching the rear suspension arm. In this case, the rotation of the bolt moves the inner attachment point of the lever back and forth along the course of the car. This movement changes the toe angle of the rear wheel.
Checking the convergence of the rear wheels is carried out on an optical stand.
The table below shows the dependence of the toe of the rear wheels on the angle of the longitudinal inclination of the vehicle platform. This dependence does not apply to vehicles with air suspension of the rear wheels, since during the operation of such a vehicle it is possible to adjust the level of the body in order to maintain it at a constant level.
