Do you know what situations require the use of a dynamic 4-wheel alignment instrument?

The conditions where 4 wheel alignment is required are as follows:

① The steering wheel is not straight when the car is driving straight on a flat road.

② The brake disc is abnormally worn and there is a serious condition of tire wear.

③The car's steering wheel will shake up and down.

④The car has been involved in a collision.

⑤When the car is driving straight on a flat road, it will slide to the left or right.

⑥The car will vibrate and become unstable.

⑦ There are mayflies while driving.

⑧When disassembling and replacing suspension training, automobile steering system, triangle frame or crankshaft connecting rod and other automobile chassis parts.

What are the adverse effects of 4 wheel alignment errors?

Don't underestimate these parameters. If a parameter is abnormal, or a slight deviation in one angle, it may have a great impact on the normal driving of the car.

The most common problem is the car's deviation. That is, if you keep the steering wheel straight and drive forward, the car will deviate to the left or right. The driver can only keep adjusting the steering wheel. If you are not careful, the car will deviate several meters to the left or right, which has a great impact on driving safety.

There is also uneven wear of tires, which is also known as "tire wear". This situation is difficult to detect if the tires are not inspected. Long-term use of the car will cause the uneven wear of the tires to be very serious, seriously affecting the service life of the tires. I have seen good tires being rolled into "bald tires", which is very dangerous. Not only is the road adhesion seriously reduced, but there is also the possibility of tire blowout at any time.

In addition to these common effects, improper 4-wheel alignment can also cause the car to drift, slide, turn unstable, wear and tear of suspension components, and other common faults, which seriously affect driving safety. Therefore, it is absolutely correct to pay attention to 4-wheel alignment.
