Certain scientific research shows that 70% to 80% of small and heavy vehicles in the world have problems with inaccurate positioning of their wheels and axles, which will lead to waste of money and ecological resources in the form of higher gasoline and diesel consumption and increased tire damage. Of course, large trucks also need to do four-wheel alignment. The following four-wheel alignment manufacturer analyzes why large trucks need to do four-wheel alignment.

①Low tire pressure standard

On the highway, the sideways wind will cause the large truck to deviate. If it is always on the side of the road, it will cause the driving deviation. The side with low tire pressure will also cause the driving deviation. At this time, it is necessary to do a four-wheel alignment.

② Abnormal direction changing system

The quality of the turning system will also affect the driving safety of the truck. If the gap of each assembly line is too large or the bearing is too loose, the kingpin sleeve is damaged, which will cause the truck to shake on the road and cannot maintain the normal driving track. If the turning arm or the turning joint is deformed, it will often cause the truck to hesitate or turn ineffectively. The truck will immediately lose control completely, and it is necessary to do a four-wheel alignment at this time.

③Suspension system abnormality

Due to the failure of the suspension system, the running deviation is caused, such as the interruption of the swing arm and the steering rod movement, which will affect the running deviation of the car. With the completion and opening of domestic highways, buses, large buses, heavy vehicles, and large trucks are now put into operation. At present, wheel alignment has become indispensable. The four-wheel alignment of the car can solve the abnormal damage of the tire suspension parts and improve the driving reliability of the car.
