* Data in brackets for a vehicle without load.
The difference in the longitudinal angles of inclination of the steering axes of the right and left wheels must not exceed 30'.
Before adjusting the wheel alignment angles, check the tire pressure, the clearance in the front wheel hub bearings, and the serviceability of the shock absorbers (for absence of rod jamming), radial and axial runout of tires, clearance in the upper ball joints of the suspension, free play of the steering wheel. Eliminate any detected faults by adjusting or repairing the specified units. Checking and adjusting the wheel alignment angles can be carried out on a vehicle both with a full load and without a load, however, checking on an unloaded vehicle gives less accurate results. Therefore, in critical cases, it is recommended to check and set the angles on a vehicle under a static load of 320 kgf, which approximately corresponds to the weight of four people and a load of 40 kg in the trunk.
The car is loaded with special weights that are suspended from the bottom of the body, or ballast (280 kg) distributed over the seat cushions in the trunk (40 kg). The front seats should be in the middle position of their longitudinal travel. The load in the trunk is distributed evenly, and the lack of gasoline is compensated for by a load placed on the right side of the trunk.
After installing the car on the stand, immediately before checking the angles, "squeeze" the car's suspension, for which purpose apply 2-3 times a force of 40-50 kgf, directed from top to bottom, first to the rear, then to the front bumper. In this case, the car's wheels should be directed straight. Observe the following sequence of checking and adjusting the wheel alignment angles: longitudinal tilt angle of the steering axis, camber angle, wheel toe-in.
Angle of longitudinal inclination of the axis of rotation
If, when checking, the angle does not correspond to the data given earlier, change the number of adjusting washers 27 and 28 installed between the lower arm axis and the cross member (see fig. 156), following Table 8. When adjusting the wheel alignment angles, it is permissible to use U-shaped adjusting shims, which should be directed with the slot downwards. After adjustment, tighten the nuts with a torque wrench and check the angle again.
Front wheel camber angle
If it differs from the norm, adjust it also by changing the number of adjusting washers 27 and 28 (see fig. 156), using Table 8. To increase the camber, remove the same number of washers from both bolts, and to decrease it, add them.
Front wheel alignment
If the wheel alignment is incorrect, loosen the side tie rod clamps 1 (see fig. 183) and key 67.7813.9504 turn both couplings 5 by the same amount in opposite directions. In this case, the couplings are screwed or unscrewed with the rod end and change the length of the rods. After completing the adjustment, install the clamping clamps with the slot horizontally and backwards with an upward or downward deviation of no more than 60° and tighten them in this position. When the nuts are tightened, the edges of the clamp slots should not touch. Key 67.7813.9404 is made similar to pipe wrenches and can be replaced with them.
