The front wheels of the car are located at certain angles with respect to each other, which are called collapse and convergence.
This provides him with good roadability, so it's very important to adjust them.
It is quite feasible to perform a break-up in a garage. This requires a nylon thread and the simplest adjustment tool.
In order to make the collapse and convergenceFront axle, we install the machine with the front wheels on specially prepared support platforms. It is very important to pay attention to the fact that the load on both wheels should be distributed evenly. The first thing we do is collapse. It is carried out by turning the columns. To measure the deviation of camber from the nominal value, it is necessary to take a nylon thread, tie a weight to it and place the resulting plumb so that it passes along the axis of the wheel. We measure the distance from the filament to the rim at its upper and lower points, after which we calculate the difference. If it exceeds the allowable value for your car brand, adjust it by adjusting the position of the stand with a special key. To monitor the result of the adjustment, we re-conduct the measurements.
Convergence can be done in a similar way. We make the thread tension from the rear wheel at the center of the wheel disks parallel to the floor. In the same way measure the distance from the front and rear edge of the disc to the thread. We analyze it and if necessary adjust the convergence by changing the length of the steering rods. The steering wheel during adjustment and measurement should be in the central position, and it is desirable to fix it. During the measurement, the error that may occur due to the curvature of the wheel disks must be taken into account. For a more accurate measurement, it is recommended to rotate the wheel by making several measurements in different positions.
To make a breakdown and convergence is not so difficult, this procedure should be done regularly for prevention, and also after replacing the front pillars, silent blocks, seals, rods or levers.
