After a certain period of operation, the car will be affected by some factors, such as wear and tear, repair, replacement, etc., which leads to the change of vehicle location information.
If the parameters change more than the set value, then the operation of the car becomes abnormal. For example, the tires are abnormally worn, the car cannot drive in a straight line normally, and it is difficult for the steering wheel to return to the center, so it is necessary to carry out four-wheel alignment, which is very necessary.
Generally, the steps of wheel alignment are done.
1. When the vehicle is driven to the automatic lifting platform, the front wheel must be parked in the middle of the turntable and its position must be tested, including tire pressure, suspension, chassis, etc.;
2. The next thing is the test data, install sensors on the four wheels, fix the steering wheel and brake pedal, and then lift the car and set some parameters for testing
3. According to the instructions on the screen of the locator, the green light is normal, and the red light is abnormal
4. Finally, the positioning adjustment is carried out, and based on these data, the position data of the four wheels of each tire are adjusted accordingly, and adjusted according to the size of the error
5. After commissioning, check the vehicle.
How long does it take to complete the four-wheel alignment?
Wheel alignment usually takes 30 minutes, and for multi-adjustment, quad alignment takes one to three hours. Under normal circumstances, as long as the toe of the front wheel is adjusted, it can be completed in 20 minutes. If you adjust the "camber" and "vertical shaft tilt" of the front wheels, it can be done in one hour;If you want to adjust the "toe" or "camber" of the rear wheels, it takes more time, usually 2-3 hours.
