Checking and adjusting the wheel alignment is necessary to ensure good vehicle stability and handling, as well as uniform tire wear during operation

They check and adjust the wheel alignment angles on special stands according to the instructions for their operation.

The discrepancy between the actual values ​​measured on the vehicle and the control values ​​indicated in the tables is due to wear or deformation of the suspension parts or deformation of the body.

The values ​​given in the table are valid for vehicles with a full fuel tank and a load of 70 kg in the front seats.

After installing the car on the stand (immediately before checking the corners), "squeeze" the suspension of the car, applying two or three times a force of 392-490 N (40-50 kgf), directed from top to bottom, first to the rear bumper, and then to the front .

The wheels of the car must be parallel to the longitudinal axis of the car.

When checking and adjusting the front wheel alignment, first check the caster angle, then the camber angle, and lastly the toe-in.

After wheel alignment is complete, program the torque sensor and steering angle using the scan tool.

Panning Angle

The angle of longitudinal inclination of the axis of rotation of the front wheel is formed by a vertical line and a line passing through the middle of the upper support of the telescopic strut and the center of the sphere of the ball joint fixed to the lower arm of the front suspension.

Adjusting the angle of the longitudinal inclination of the axis of rotation is not provided for by the design of the car.

If the angle deviates from the nominal value, replace damaged and deformed parts.

Camber

The camber angle of the front wheels is characterized by the deviation of the mean plane of rotation of the wheel from the vertical.

Adjusting the camber angle of the front wheels is not provided for by the design of the car.
