Any discrepancy between the actual values measured on the vehicle and the reference values specified below is due to wear and deformation of suspension parts or deformation of the body.
WARNING: Replacing or repairing suspension components may cause changes in wheel alignment, so checking wheel alignment is essential.
Front wheel alignment angles at the vehicle"s own weight are given in Table 4.3, the rear wheel alignment angles at the vehicle"s own weight are given in Table 4.4.
After installing the car on the stand (immediately before checking the angles), "squeeze" the car's suspension, applying a force of 392-490 N (40-50 kgf) two or three times, directed from top to bottom, first to the rear bumper, and then to the front. The car's wheels should be parallel to the longitudinal axis of the car.
When checking and adjusting the front wheel alignment angles, first check the caster angle, then the camber angle, and lastly the toe-in.
Table 4.3 Front wheel alignment angles
Table 4.4 Rear wheel alignment angles
Angle of longitudinal inclination of the front wheel pivot axis 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. The design of the vehicle does not provide for adjustment of the longitudinal tilt angle of the steering axis. If the angle deviates from the nominal value, replace damaged and deformed parts.
Front wheel camber angle is characterized by the 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 for by the design of the car.
Front wheel alignment is the angle between the plane of rotation of the wheel and the longitudinal axis of the car. The toe-in of the front wheels is adjusted by changing the length of the steering rods.
Check the following rear wheel alignment angles.
Rear wheel camber angle is characterized by the deviation of the average plane of rotation of the rear wheel from the vertical. Adjustment of the camber angle of the rear wheels is not provided for by the design of the car.
Rear wheel alignment is the angle between the plane of rotation of the rear wheel and the longitudinal axis of the car. The toe-in angle is adjusted by rotating the adjusting bolts that secure the lower rear arm to the rear suspension crossmember.
