To ensure good stability and controllability of the car, as well as uniform tire wear during operation, it is necessary to check and adjust the wheel mounting angles

Wheel mounting angles are checked and adjusted on special stands, according to their operating instructions

If the angles of the actual values measured on the car do not correspond to the values indicated below, then this is due to wear and deformation of suspension parts or deformation of the body

When repairing and replacing suspension parts, it is necessary to check the mounting angles of the wheels

Wheel mounting angles

Camber angle of the front wheels:

- the maximum permissible value is 0º17ʹ +1º;

- the maximum difference of values for the left and right wheels is 1º30ʹ

Convergence of the front wheels:

- the maximum permissible value is 0º11 ± 0º22ʹ;

The angle of longitudinal inclination of the axes of rotation of the front wheels:

- the maximum permissible value is 3º47ʹ +1º;

- the maximum difference of values for the left and right wheels is 1º30ʹ

Camber angle of the rear wheels:

- the maximum permissible value is 1º13 ± 1º;

- the maximum difference of values for the left and right wheels is 1º30ʹ

Convergence of the rear wheels:

- the maximum permissible value is 0º11 ± 1º;

- the maximum difference of values for the left and right wheels is 15ʹ

The values are valid for vehicles with a fully filled fuel tank and a load of 70 kg in the front seats

After installing the car on the stand (immediately before checking the corners), it is necessary to squeeze the suspension of the car, applying two or three times the force 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 positioned parallel to the longitudinal axis of the car

When checking and adjusting the installation angles of the front wheels, you must first check the angle of the longitudinal tilt of the pivot axis, then the camber angle and last of all the convergence of the wheels

The angle of the longitudinal inclination of the axis of rotation of the front wheel 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 bearing mounted on the lower arm of the front suspension

Adjustment of the angle of the longitudinal inclination of the axis of rotation is not provided by the design of the car

If the angle deviates from the nominal value, deformed parts must be replaced

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

Adjustment of the camber angle of the front wheels is not provided by the design of the car

The convergence of the front wheels is the angle between the plane of rotation of the wheel and the longitudinal axis of the car

The convergence of the front wheels is regulated by changing the length of the steering rods

The camber angle of the rear wheels is characterized by a deviation of the average plane of rotation of the rear wheel from the vertical

Adjustment of the camber of the rear wheels is not provided by the design of the car

The convergence of the rear wheels is the angle between the plane of rotation of the rear wheel and the longitudinal axis of the car

Checking and adjusting the camber of the wheels of the Mazda 6

The convergence of the rear wheels is adjusted by rotating the adjusting bolts of the rear lower lever attachment to the rear suspension subframe
