- Wheel alignment angles are an important parameter when operating a vehicle and significantly affect vehicle stability, tire wear and fuel consumption.
- Due to the design of the front suspension, a change in one of the angles (longitudinal inclination of the wheel turning axis, camber. transverse inclination of the wheel steering axis, toe and their vibrations) has a greater or lesser influence on the values of other angles, with the longitudinal inclination of the wheel turning axis having the greatest influence.
- Install the equipment for measuring wheel alignment angles in accordance with its operating instructions.
- On a turntable, set the steering to the midpoint position and lock the steering wheel.
- Raise the vehicle by sliding the lift arms under the body.
- Eliminate wheel wobble.
- Place the front wheels of the car on turntables.
- Use a special device to block the brake pedal while pressed.
- Rock the car body until all suspension elements are in their normal position.
- Check if the sizes are the same (X, fig. 10.31) from tie rod hexagons to tie rod ends. The X dimensions must be the same on both sides of the vehicle with a tolerance of 1.5mm.
- Turn the steering wheel to set the front wheels to move straight ahead. In this position, set the turntables to zero. Check the alignment angles of the front wheels in the following sequence - the caster angle of the wheel rotation axis:
- angle of transverse inclination of the wheel turning axis;
- wheel camber angle;
- wheel toe angle.
