- Wheel alignment is an important parameter when operating a vehicle and has a significant impact on vehicle stability, tire wear and fuel consumption.
- Due to the design of the front suspension, one of the angles changes (longitudinal tilt of the wheel turning axis, camber. transverse tilt of the wheel turning axis, toe-in and their oscillation) has a greater or lesser influence on the values of other angles, with the longitudinal inclination angle of the wheel's turning axis having the greatest influence.
- Install the wheel alignment equipment in accordance with its operating instructions.
- On a turntable, set the steering to the center point and lock the steering wheel.
- Raise the vehicle by placing the lift arms under the body.
- Eliminate wheel runout.
- Place the front wheels of the vehicle on turning pads.
- Use a special device to lock the brake pedal in the depressed position.
- Rock the car body to ensure that all suspension components are in their normal position.
- Check if the sizes are the same (X, Fig. 10.31) from the tie rod ends to the tie rod ends. The X dimensions must be the same on both sides of the vehicle with a tolerance of 1.5 mm.
- Turn the steering wheel to set the front wheels for straight-ahead driving. In this position, set the turning pads to zero. Check the front wheel alignment angles in the following sequence - longitudinal inclination of the wheel pivot axis:
- angle of transverse inclination of the wheel rotation axis;
- camber angle;
- wheel toe angle.
