Four-wheel alignment is necessary for those who drive at high speeds or on dangerous roads for a long time. But as a car owner, you should know what the four-wheel alignment is mainly for the car and what kind of situation the car should be in before the four-wheel alignment is done. Generally, a newly purchased car, at least within the first 100,000 kilometers, does not consider the four-wheel alignment. The 4S shop uses the inspection instrument to check the parameters of the four wheels as a basis. If there are some serious errors, it needs to be adjusted to ensure the good driving performance and reliability of the car.

The four-wheel alignment of a car usually starts from these aspects, such as the castor angle, the kingpin inclination angle, the front tire camber, and the front wheel toe. These four indicators are all necessary to check for the four-wheel alignment. Generally, the rear tire alignment value is similar to the front tire alignment value, but the rear tire alignment of most cars cannot be adjusted.

If the 4-wheel alignment is not done properly, the damages include accelerated wear of the brake disc, deviation of the car direction, shaking of the steering wheel, and higher fuel consumption. If your car has such problems due to the 4-wheel alignment, it is recommended to return to the 4S shop for another inspection.

Let's talk about the difference between rotor balancing and wheel alignment. Many people think that rotor balancing is wheel alignment, but it is not. In simple terms, rotor balancing is to adjust the wheel balance so that the tires are always in the same boat. If your car has changed tires or rims, or basic maintenance, you should do rotor balancing when you remove the tires for inspection.
