To ensure good vehicle stability and handling, as well as uniform tire wear during operation, it is necessary to check and adjust the wheel alignment
The wheel alignment angles are checked and adjusted on special stands, according to their operating instructions
If the angles of the actual values measured on the vehicle do not correspond to the values indicated below, then this is due to wear and deformation of the suspension parts or deformation of the body
When repairing and replacing suspension parts, it is necessary to check the wheel alignment
Wheel alignment
Front camber:
- - limit value - 0º17ʹ +1º;
- - maximum difference between left and right wheel values 1º30ʹ
Toe-in front:
- limit value - 0º11ʹ ±0º22ʹ;
The angle of the longitudinal inclination of the axes of rotation of the front wheels:
- - limit value - 3º47ʹ +1º;
- - maximum difference between left and right wheel values 1º30ʹ
Rear camber:
- - limit value - 1º13ʹ ± 1º;
- - maximum difference between left and right wheel values 1º30ʹ
Rear wheel alignment:
- - limit value - 0º11ʹ ± 1º;
- - maximum difference between left and right wheel values 15ʹ
Values 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 (just before checking the corners), you need to squeeze the car's suspension, 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
The caster angle of the front wheel axis is formed by a vertical 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 attached to the lower arm of the front suspension
Adjustment of the angle of the longitudinal inclination of the axis of rotation is not provided for by the design of the vehicle
When the angle deviates from the nominal value, it is necessary to replace the deformed parts
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
Toe-in is the angle between the plane of rotation of the wheel and the longitudinal axis of the vehicle
Toe-in of the front wheels is regulated by changing the length of the steering rods
Rear camber is characterized by the deviation of the mean plane of rotation of the rear wheel from the vertical
Adjustment of the camber of the rear wheels is not provided for by the design of the car
Rear wheel toe-in is the angle between the plane of rotation of the rear wheel and the longitudinal axis of the vehicle
Rear wheel toe-in is adjusted by turning the adjusting bolts securing the rear lower arm to the rear suspension subframe
