1. Check the condition of the tires and their pressure.
2. Check the wheel runout (permissible values are given in the section "Data for adjustments and control").
3. Check that there is no play in the wheel bearings, suspension and steering.
4. Check the operation of the telescopic struts.
5. Check the position of the body relative to the ground (in an unloaded state).
Collapse, longitudinal and transverse tilt of the pivot axis. These angles are specified by the suspension design and cannot be adjusted during operation. The angle values are given in the section "Adjustment and control data". If any of the angles are not within the permissible limits, it is necessary to check the suspension flyers, replacing damaged or worn ones.
Convergence. Toe-in is measured as follows.
1. Place the vehicle on a level surface and press down on the front end to stabilize the body position.
2. Roll the car in a straight line for a distance of about 5 m.
3. Make marks on the back of the treads of both tires. The marks should be located in the middle of the tread at the height of the center of the hub.
4. Measure the distance A between the marks.
5. Slowly move the vehicle forward until the wheels turn 180° and the marks are at the front.
If the wheels have turned more than 180°, start the measurement again. Do not move the car backwards.
6. Measure the distance B and determine the toe-in. The necessary data is contained in the section "Data for adjustments and control".
7. If necessary, adjust the toe-in by changing the length of the steering rods. To do this, loosen the locknuts and turn the adjusting rods to set the desired toe-in. The nominal value L, as well as the tightening torque of the locknuts, are given in the chapter "Steering". Change the length of both rods simultaneously by the same amount.
