For a new, run-in vehicle in running order and with a payload of 2205 N, which is distributed 735 N on the two front seats and 735 N on the center of the rear seat, the wheel alignment angles should have the following values:
* For equipped vehicle.
Before adjusting the wheel alignment angles, check the air pressure in the tires, radial and axial runout of the wheel disks (no more than: axial - 1 mm, radial - 0.7 mm), free play (play) of the steering wheel (no more than 5°), free play (play) in the front wheel hub bearings (unacceptable), as well as the technical condition of the suspension parts and units (absence of deformation, destruction and wear of rubber-metal hinges, wear of the upper support of the suspension strut). The detected faults are eliminated.
After installing the car on the stand, immediately before checking the corners, "squeeze" the car's suspension, applying 2-3 times a force of 392-490 N, directed from top to bottom, first to the rear bumper, and then to the front. In this case, the car's wheels should be parallel to the longitudinal axis of the car.
The order of checking and adjusting the wheel alignment angles is as follows: longitudinal tilt angle of the steering axis; collapse; convergence.
Angle of longitudinal inclination of the axis of rotation
If this angle does not correspond to the data given above, adjust it with nuts 4 (see figure 99) with a loosened nut securing the tie rod to the lower suspension arm. To decrease the longitudinal tilt angle of the pivot axis, screw nuts 4 onto the tie rod, and vice versa, to increase the angle, unscrew the nuts from the tie rod until the required angle is established.
Front wheel camber angle
If the camber angle differs from the norm, then it is adjusted. To do this, loosen the nuts of the upper and lower bolts and, turning the upper adjustment bolt 8 (see figure 97), set the required camber angle. After completing the adjustment, tighten the nuts to a torque of 121 N·m.
Convergence
If the toe-in is not within the norm, loosen the lock nuts 2 (see figure 113) and, rotating the inner tips 3 by the same angle, set the required toe-in. In this case, the front wheels should be in the position of straight-line movement of the car, and the steering rack - in the middle position, that is, mark A on the steering gear housing and mark B on the boot should be aligned. After adjusting the toe-in and tightening the lock nuts of the inner tips, it is necessary to exclude possible twisting of the steering gear boots.
