The four wheel alignment of the car is only checked and cannot be corrected, and the correction is a

Under normal circumstances, if there is no damage to the chassis parts, you can adjust the calibration, but if there is damage to the parts, you need to replace the parts before adjusting, if you do a single four-wheel alignment, there is no additional charge.

Generally, there are adjustments, but some stores that do positioning charge so much in order to make money.

The function of the four-wheel alignment is to keep the car stable and straight, and to steer lightly, and to reduce the wear and tear of the tires and steering parts of the car while driving. The computer of the maintenance industry "four-wheel aligner" stores a large number of data on the four-wheel alignment of the car model, the four-wheel alignment instrument first measures the current four-wheel alignment parameters of the car, and then the computer automatically compares with the storage value of the corresponding model, calculates the deviation value of the four-wheel alignment of the car, and the maintenance personnel can be restored to the original state according to the prompts of the locator. When driving the vehicle when you feel that the direction of the steering is heavy, shivering, misaligned, not homecoming, or find that the tires are unilaterally worn, wavy worn, block worn, eccentric wear and other abnormal wear and tear, as well as when driving, the car feels floating, bumpy, swaying and other phenomena, you should do four-wheel alignment.

Dynamic balancing and four-wheel alignment are not the same thing, when the vehicle is found to be shaking the steering wheel or the wheel has some rhythmic abnormal sound when driving at high speed, it may be that the wheel should be dynamically balanced, especially when the tire is replaced, the hub or the tire is repaired, the wheel is hit too much, and the balance weight is lost due to bumps. The Internet can only explain the theoretical things to you, and if the actual vehicle is used abnormally, it must be repaired in time to solve the problem.

Four-wheel alignment practice:

1. When the car is aligned with four wheels, you need to park the car in the appropriate card slot, so you must control the speed, listen to the guidance of the maintenance master, and tighten the handbrake and hang up the gear after parking the car;

2. When the car is aligned with four wheels, it is necessary to take care of the operation of the maintenance workers and do not let them damage the tires, because some hand-born repairmen are easy to prick the wrong position, and it will be troublesome to hurt the tires, so you should point it out in time;

3. When the car is aligned with four wheels, it is necessary to shake the tires by hand to check the chassis parts, check whether the steering rod, ball joint, swing arm, bearing, etc. are loose, and pay attention to the selection of model information, which is used as the basis for measuring whether the chassis data of the car is correct or not, so the choice of the model can not be wrong. After finding the corresponding model year, the effect is good;

Four-wheel alignment is simple to say, but it's actually a hassle to do. You don't need to spend time understanding how wheel alignment works. Just like when we drive, it is not necessary to have a thorough understanding of how a vehicle works.

We just need to be able to drive. Other things need to be left to professionals and equipment. The friction is different depending on the tire pattern, so when changing the tire, it is usually replaced in pairs.

If a one-sided wheel has recently been replaced, the vehicle will want a larger friction side offset and a tire with the same pattern.

Shock absorption damage will not only cause body vibration, but also cause shock absorber oil leakage, spring deformation, shock absorber tower damage, etc., shock absorption tower damage, etc., which can be solved after replacement. Any of the above situations are mutually influential, so don't blindly do a four-wheel alignment, rule out all possible influencing factors, and then choose to do a four-wheel alignment. Of course, most staff members will ask the owner about the situation before doing the four-wheel alignment, and do a full inspection before starting the hands-on theoretical positioning.

If you don't ask anything, just do a four-wheel alignment 4s shop or auto repair shop, please leave quickly, this is also too unprofessional.

Four-wheel alignment is a standard, mainly for the vehicle suspension and steering system, as long as the vehicle's four-wheel and suspension system is within this standard, it is qualified, and others do not need to be managed. In order to solve the cause of the four-wheel alignment problem, we first need to understand the structure of the vehicle's suspension. We all know that the suspension, one of the three parts of our vehicle, is very important to the vehicle.

The quality of the suspension determines the contact of the tires with the ground. If there is a problem with the suspension, you need to do a four-wheel alignment and restore the position of the four tires to the manufacturer's factory level.

Losing the round is also one of the important reasons for eating tires. Some people don't do balancing after changing their tires, or even replace them themselves. This is wrong.

Therefore, if you find that you can do the dynamic balancing first by eating tires, you should also develop the habit of doing dynamic balancing when changing tires. The car is sometimes heavy in direction, sometimes light, and the steering wheel shivers at high speeds, mainly because the car's suspension angle is abnormal and requires four-wheel alignment. The owner can experience whether there is a problem with the four-wheel alignment, on the flat and straight road with the same tire pressure of the four cars, return to the steering wheel, and then release the steering wheel and step on the accelerator, if the vehicle can drive in a straight line, there is no problem with the four-wheel alignment; If the vehicle is offset to the left or right, there is a problem with the four-wheel alignment.

Whether the problem is serious or not depends on whether the angle of the offset is large.

If the data of the 4 wheels is not the same, you must do the 4 wheel alignment, if you don't do it, it will be very bumpy, very dangerous, and there may be traffic accidents.

It is necessary to do 4 wheel alignment, because the data is different, so the tightness of the tire and the ground and the parts of the tire are already not equal, and it is easy to slip at this time.

Yes, so that the safety of driving can be guaranteed, and the stability of the tires can be improved.

Inaccurate four-wheel alignment needs to be adjusted to the 4S shop, and inaccurate four-wheel alignment will lead to vehicle deviation and other situations. Wheel alignment concept:

1. The four-wheel alignment is based on the four-wheel parameters of the vehicle, and is adjusted to ensure that the vehicle has good driving performance and certain reliability;

2. The installation between the steering wheel, the steering knuckle and the front axle of the car has a certain relative position, and the installation with a certain relative position is called steering wheel alignment, also known as front wheel alignment;

3. The front wheel positioning ant includes four contents: kingpin camber (angle), kingpin camber (angle), front wheel camber (angle) and front wheel toe. This is for the two steering front wheels, for the two rear wheels also exist with the relative position installed between the rear axle, called the rear wheel alignment, the rear wheel alignment includes wheel camber (angle) and the rear wheel toe-in one by one, so that the front wheel alignment and the rear wheel alignment are called four-wheel alignment.

How to deal with inaccurate wheel alignment:

1. The car is driven to the positioning lift, and the front wheel needs to be stopped in the middle of the loading plate for positioning detection, including tire pressure, suspension and chassis detection;

2. Then carry out data detection, install sensors on the four wheels, fix the steering wheel and brake quietly noisy car pedals, lift the car, and set the parameters for testing;

3. Finally, the positioning adjustment, according to the data, according to the degree of deviation, the four-wheel alignment data of each tire is adjusted accordingly, and the debugging is over, and the car can be inspected on the road.

The car deviates from the potato ear is the process of the car driving in a straight line on a flat road, and the quality of the steering system will also affect the straight line of the car. The car deviates to one side on its own, causing the car to drive inconsistently with the center line of the front and rear axles and the center line of the driving trajectory. If the deviation is light, it will cause tire gnawing and tire scrapping, and at worst, it will cause tire burst, vehicle loss of control and other dangerous conditions.

The phenomenon of inaccurate four-wheel alignment: 1. When the car has deviation, steering accuracy deteriorates, the steering wheel is not correct, and the tire eats, it is necessary to do four-wheel alignment. Tire eating refers to the same tire, the wear of both sides is different, or the wear of the left and right tires is different; 2. After replacing or repairing the suspension, steering and other systems, it is also necessary to do four-wheel alignment; 3. Four-wheel alignment directly affects the safety and stability of the car, doing four-wheel alignment can keep the best angle between the tire and the car body, reduce the wear and tear between the tire and the steering parts during the driving process, and ensure the close combination of the tire and the ground, and the car can maintain a stable straight line.

The deviation of the car is the process of the car driving in a straight line on a flat road, and the quality of the steering system will also affect the straight driving of the car. The self-deflection to one side leads to a running phenomenon in which the center line of the front and rear axles is inconsistent with the center line of the running trajectory. At worst, it will gnaw on the tire and scrap it, and at worst, it will lead to dangerous situations such as tire bursts and vehicle loss of control.

The phenomenon of inaccurate four-wheel alignment:

1.The car deviates, the steering accuracy deteriorates, the steering wheel is not right, the tires are eaten, etc. Four-wheel alignment is required. Eating refers to the same tire, the wear of both sides is different, or the wear of the left and right tires is different;

2.After replacing or repairing the suspension, steering and other systems, it is also necessary to carry out four-wheel alignment;

3.The four-excitation wheel positioning directly affects the safety and stability of the car. Doing a good job of four-wheel alignment can maintain the best angle between the tire and the body, reduce the wear and tear between the tire and the steering parts during the driving of the car, ensure the close combination of the tire and the ground, and keep the car running in a stable straight line.
