What will happen to the car if there is something wrong with the four-wheel alignment?
1
Deviation/eccentric wear
If there is something wrong with the toe angle of one wheel (hereinafter referred to as the steering wheel), you will find that the steering wheel is positive, but the car is off-center. However, if there is something wrong with both wheels, such as the character of toe angle, it will not be off-center. So is the inclination angle. A wheel is lying on the ground. As soon as you give the oil, it will run away. If both wheels lie prone on the ground, they will definitely wear out, such as those cars with bad bottoms. I believe everyone has seen them on many modified cars.
2
The steering wheel is not straight
I believe many friends will encounter such a situation. It is obvious that the car is going straight, but the steering wheel is crooked. Many times, this situation is also related to four-wheel alignment, especially if there is a problem with the toe angle of one wheel, which will directly lead to the steering wheel being incorrect.
So, how often do you do a four-wheel alignment check?
1. When a general vehicle travels 20,000 kilometers or 1 year, it is recommended to do a four-wheel alignment (inspection).
2. When you go straight on the straight road, you also need to hold the steering wheel tightly to ensure that the vehicle does not deviate, which means that your car needs four-wheel alignment.
3. When the car is driving normally, it feels like the body is fluttering or shaking, just like turning on a rough road, which means that your car may have problems with four-wheel alignment, so it is recommended to check it in time.
If you find that one side of the tread of the front and rear wheels of your car is particularly worn, you need to check it.
5. When the car goes straight, release the steering wheel, and the car will automatically pull left or right, indicating that your car needs four-wheel alignment.
6. When the vehicle has had a collision accident (suspension system injury), steering or suspension system maintenance, it is best to do a four-wheel alignment.
Choose a more professional positioning store.
Many people think that the technical requirements for skilled workers to do four-wheel alignment are relatively low, and the entry threshold is low, just because four-wheel alignment instruments are expensive (domestic four-wheel alignment instruments are generally hundreds of thousands, and imported instruments are more expensive, generally more than 200,000), so many people like to judge the strength of the garage according to the quality of equipment.
Actually, it's not. For four-wheel positioning, the equipment itself can only account for half of the proportion, and more is the experience of technicians. For many special models, old and accident models, normal adjustment methods may not solve the problem, and technicians often need rich experience and even take some extraordinary measures for debugging. So, if your car needs four-wheel alignment, the editor suggests that you can go to those stores that specialize in positioning.
Don't guess These situations have nothing to do with four-wheel alignment!
1
Change tires and rims ≠ Positioning.
Simply put, when you change the rims and tires, you just change the attributes of the wheels and do dynamic balance, while four-wheel alignment refers to the attributes of suspension, which are two different things. Whether changing tires or changing rims, as long as the dimensions are the same, there is no need to do four-wheel alignment.
2
Directional jitter in a certain speed range
Many car owners have encountered this situation when driving: when the car drives to a certain speed range, the steering wheel will shake, and after this speed range, it will be fine. This situation is generally a problem of wheel dynamic balance, not a four-wheel alignment fault.
three
When you step on the brakes, your direction will shake.
This situation is also relatively common, but in fact, old cars are more likely to appear. General steering knuckle looseness, caliper bracket looseness and brake disc deformation will all lead to this situation. I suggest you go to the auto repair shop for inspection.
four
Accelerated jitter
This situation is generally caused by the aging of suspension components, especially the damage of transmission shaft and ball cage. If it is a predecessor, it is mostly the steering wheel jitter. If it is a rear drive, it may become a body shake. The car swung out as soon as the accelerator was given.
five
tyre pressure
Although this situation is the lowest, it is also the most common. If the tire pressure of the left and right cars is very different, it will easily lead to deviation. At this time, you may think it is a problem of four-wheel alignment. It is very important to form good habits. Try to check the tire pressure regularly.
How to reduce the number of four-wheel alignment?
1. No matter what kind of car you are, drive slowly on the bumpy road, and remember not to accelerate quickly. Severe vibration will inevitably affect the four-wheel alignment of vehicles.
2. Try to avoid the impact of external forces on the front wheel of the car, such as quickly crossing the pit and rushing to the sidewalk steps.
3. Pay attention to side parking. This situation has been edited many times, especially for drivers with poor parking level. They like to find kerbs with their wheels. Although this method can help them park in the parking space smoothly, I also find that they often hit the direction very hard during parking. At this time, if the wheels can no longer rotate, it will easily lead to problems in four-wheel alignment.
abstract
In most cases, there are problems with the four-wheel alignment of our car, and 90% of them are caused by our own bad driving habits or random modification. It is very important to develop good driving habits and regularly check the four-wheel alignment of vehicles. Finally, I hope everyone will stop clamoring for positioning when changing tires or rims. You should be very clear about whether to do positioning and when to do it.
