What is a four wheel alignment?

As the number of cars continues to rise, vehicle safety issues are receiving more and more attention. Among them, four wheel alignment, as an important part of ensuring the safe driving of cars, is valued by more and more car owners. So, what exactly is four wheel alignment?

Four wheel alignment is defined as the process of accurately adjusting the position and angle of the four wheels of a car so that these parameters meet the standard values ​​set by the vehicle manufacturer. During the driving process of the car, the position and angle of the wheels will change due to various factors, such as road bumps and collisions. When such changes occur, four wheel alignment becomes particularly critical. ​

The driving stability of the vehicle will be affected by inaccurate four wheel alignment. If the wheel alignment parameters deviate from the standard, the car is likely to be caused to deviate, which not only increases the difficulty of driving, but also greatly increases the risk of traffic accidents. At the same time, tire wear will also be aggravated by incorrect four wheel alignment. Uneven tire wear will not only shorten the service life of the tire and increase the economic burden of the owner, but may also cause serious safety hazards such as tire blowouts during driving. ​
In real life, accidents caused by four wheel alignment problems occur from time to time. For example, not long ago, on a main road, a car suddenly deviated from the road and collided with the roadside guardrail because the wheel alignment had not been adjusted for a long time. Fortunately, the driver was only slightly injured. After this incident, relevant departments have increased supervision of the automobile repair and maintenance industry, requiring all repair shops to pay attention to four wheel alignment services and calibrate equipment regularly. ​
Auto repair experts also remind car owners that in order to ensure driving safety, they should regularly check the four wheel alignment of the vehicle. Generally speaking, every 10,000 to 20,000 kilometers of driving, or when the vehicle deviates or the tires are abnormally worn, it should be sent for four wheel alignment detection and adjustment. Only by ensuring that the four wheel alignment parameters are accurate can the vehicle always be in the best driving state and ensure driving safety.
