What happens when a car turns unusually?

Generally, the vehicle steering machine has abnormal noise when turning, and there are the following possibilities:

1. The internal damage of the vehicle steering machine and the internal gear mechanism are faulty.

2. The suspension of the vehicle is faulty, such as the shock absorber top rubber bearing, the upper and lower swing arm ball joints are loose, etc., which will also cause abnormal sound in the direction or uneven road. Generally, checking the chassis can detect problems.

3. The loosening of the balance bar or the ball head of the balance bar may also cause abnormal noise.

4. If it is mechanical hydraulic assistance, it may be that the booster pump or belt produces abnormal noise. Generally, when turning, the pressure of the system will be very high, and the mechanical hydraulic booster pump will have a large working load, which is easy to produce abnormal noise.

5. In the case of electric power assist, the internal power assist motor or other rubber parts may be damaged.

6. The fixed rubber sleeve of the steering machine is loose or loosened in other places, such as the ball head in the direction machine or the ball head outside the direction machine is loose.

7. When the tire is turning, it rubs to other places or the wheel lining is loose or not, causing abnormal noise.

8. The wheel half-shaft cage is abnormal, the internal lubrication of the cage is not in place or damaged, and it may also cause abnormal noise by turning in the direction.

If the vehicle turns and often makes abnormal noises, it is recommended to go to the repair shop for maintenance in time to avoid the vehicle from being sick on the road and affecting safe driving, after all, the direction is a very important part of the vehicle.

Mine is when turning, changing gears but there is also a sound, the master of the 4S shop said that it is normal to change gears like this. Think about tens of thousands of cars, that's it. It's good to find a way to get the turning noise right.

1. Friction between plastic parts.

Because the steering wheel is usually made of plastic parts, if the temperature becomes colder, the plastic will harden, and there is a natural possibility of friction sound.

2. Abnormal noise coming from the steering wheel.

If the abnormal sound comes from the steering wheel, then the problem is likely to be caused by the airbag hairspring in the steering wheel, remove the steering wheel airbag hairspring and apply some butter to see if it still sounds, if it still rings, replace the airbag hairspring, because the airbag hairspring is damaged. Be careful to remove the steering wheel gently, or unplug the airbag fuse to avoid the airbag from deploying.

3. The ball joint of the steering tie rod is aging.

If the steering tie rod ball joint is aging, then it will cause the steering wheel to shake and make a sound, which is usually replaced by the steering tie rod ball joint and the four wheel alignment after replacement.

4. The abnormal sound emitted by the balance bar.

If it is not the sound of the shock absorber, then check whether the balance bar glue is loose or damaged, the balance bar glue is loose and damaged, not only will it sound when playing in the direction, but also make a sound when crossing uneven roads, and the loose balance bar glue can be solved by adding gaskets, and if it is damaged, it can only be replaced.

5. The plane bearing of the shock absorber makes an abnormal sound.

Just open the front cover to listen to whether the sound comes from the position of the top seat of the shock absorber, so that you can know whether it is the sound of the plane bearing of the shock absorber, the plane bearing of the shock absorber sounds, you can apply some butter on the plane bearing, if it still rings after coating, it can only be replaced.

6. Steering machine failure.

If the abnormal noise during steering is very large, then it may be caused by too large gear clearance between the steering machine and the steering machine, and the steering machine needs to be replaced.

7. Improper tightness or aging of the power belt.

For mechanical hydraulic assistance, if the power belt is not properly tightened or aged, there will be an abnormal sound, adjust the belt tightness or replace the belt.

If your car has abnormal noise when turning, you can judge from the above reasons, the owner pays attention to the maintenance of the car every day, and it is not very convenient for the owner to overhaul it.

The reasons for the abnormal sound of the car turning: 1. The internal damage of the vehicle steering machine and the failure of the internal gear mechanism; 2. There is a failure in the suspension of the vehicle, such as the shock absorber top rubber bearing, the loose ball joint of the upper and lower swing arms, etc.; 3. The loosening of the balance bar or the ball head of the balance bar may also cause abnormal noise. 4. If it is mechanical hydraulic assistance, it may be that the booster pump or belt produces abnormal noise. 5. The electric assist car may be damaged by the internal booster motor or other rubber parts; 6. The fixed rubber sleeve of the steering machine is loose or loosened in other places, such as the ball head in the direction machine or the ball head outside the direction machine is loose. 7. When the tire is turning, it rubs to other places or the wheel lining is loose or not, causing abnormal noise.

1. It is very likely that the gear teeth of the driving wheel are broken, or the surface is damaged, at this time, you should pull over to check, if the gear is damaged, you should replace the new gear in time;

2. It may be the abnormal sound caused by the loosening of the link parts of the wheel, the transmission of the wheel has many gears, if it is too loose, it will make a sound when cornering;

4. The car is in the running-in period, and the planetary gears of the differential are not matched with the half-shaft gears, and the abnormal noise occurs after a period of running-in period;

5. It may be that the man-made operation is poor, resulting in improper coordination of automobile parts, resulting in abnormal noise.

When the vehicle turns and turns abnormal steering noise, the owner should not take it lightly, check the chassis and steering parts as soon as possible, and eliminate the fault in time to avoid the danger of steering failure during driving. The steering mechanism is an important part of the chassis of the car, also known as the security parts, through the steering mechanism you can control the vehicle according to your own intentions, so in the process of our daily use of the car, we should also pay attention to the maintenance of the steering system.

Maintenance method: Medium and high-end cars and heavy-duty vehicles generally use power steering system, which not only greatly improves the lightness of car handling, but also improves the safety of car driving. The power steering system is formed by adding a set of steering afterburner devices that rely on the power output of the engine on the basis of the mechanical steering system. Cars generally use a pinion strip power steering mechanism.

This kind of steering gear has a simple structure, high control sensitivity, light steering control, and because the steering gear is completely closed, it does not need to be checked and adjusted at ordinary times. The maintenance of the power steering system is mainly as follows: when the level of the power steering fluid in the reservoir is regularly checked in a hot state (about 66, it feels hot to the touch), the liquid level height must be between the hot (hot) and cold (cold) marks.

If it is in the cold state (about 21), the liquid level height must be between the Add (plus) and CLOD (cold) marks. If the level does not meet the requirements, the DEXRON2 power steering fluid (hydraulic transmission oil) must be filled.

Analysis of the causes of abnormal noise when the car is steering: 1. The friction steering wheel between plastic parts is composed of various plastic parts, if the gap is too small when turning, there will always be abnormal noise, especially for new cars, it is good to run in for a period of time. If there is still an abnormal sound after the run-in, you can try to reinstall the steering wheel.

2. Friction between the steering column and the foot pad.

What happens when the car turns with abnormal noise, it may be that the steering ball head rubber pad is aging.

There are many reasons for abnormal noise during steering, such as the steering column hairpin, loose steering bolt fixing bolts, wear of the inner rack of the steering gear or loose ball joints inside and outside the steering gear, loose chassis suspension screws, loose belt of the hydraulic power steering pump, insufficient power steering oil, etc., which may lead to abnormal sound during steering.

The steering gear of the general vehicle makes an abnormal noise when turning, and there are the following possibilities:1. The internal of the vehicle's steering gear is damaged, and the internal gear mechanism is faulty.

2.Suspension failures of the vehicle, such as rubber bearings on the top of the shock absorbers, loose ball joints of the upper and lower swing arms, etc. , when driving in the direction of the burning ridge or crossing the uneven road, it will also cause abnormal noise.

Generally, a check of the chassis will reveal the problem. 3.A loose ball head of a balancer bar or a balancer bar may also produce unusual noises.

4.If it is mechanical and hydraulic power, it may be that the power pump or belt is making abnormal noises. Generally, the system pressure will be very high when turning, and the mechanical hydraulic booster pump will have a large working load and be prone to abnormal noise.

5.In the case of electric assistance, the internal assistance motor or other rubber parts may be damaged. 6.

The steering gear is loosely activated or loosened in other places, such as the ball joint inside or outside the steering gear. 7.When the tires are turning, they rub against other places or the wheel lining is not loose enough, causing abnormal noises.

8.Abnormal noise from the axle cage, insufficient or damaged lubrication inside the cage, and abnormal noise caused by steering can also occur.

With the increase in the use of modern cars, many cars have problems big and small after a long period of use. In fact, as long as we know the principle, we can actually solve some problems by ourselves without wasting money.

For example, many cars that have been used for a long time will make abnormal noises when turning. Sometimes the noise is very sharp, squeaky, and distressing, so that many car owners are confused: what happened to my car?

In fact, abnormal steering noise is usually caused by mechanical damage. First of all, we need to distinguish whether the noise is coming from outside the car or from inside the car.

1.If it is an abnormal noise coming from inside the car, it may be a noise caused by the friction between the steering column and the floor mat. This situation is caused by the improper installation of car floor mats, which will rub the steering column under the steering wheel, and sometimes serious friction problems can cause abnormal noise.

At this point, we can solve the problem by trimming the mats.

In addition, damage to the booster coupling can also produce abnormal noise. We should pay attention to this situation. If the steering wheel is turned in place and the pedals are rattling, it is likely a sign that the booster pump coupling is damaged.

At this time, we have to go to the 4S store to check in time, which will cause serious wear and tear of parts in other parts. If it takes a little longer, the whole steering system can have problems, so we must not be careless when this happens.

2.If it's an unusual noise coming from outside the car, we need to distinguish the situation carefully, because the car may be in trouble at this time.

First of all, the lack of oil in the plane bearings of the shock absorber will produce a creaking noise. This is a very common question, but it should not be sloppy. This is because the suspension system is always in a high-speed reciprocating motion during the movement of the car, and the plane bearings of the shock absorber lack lubricating oil.

At this time, it is not far from the injury of the limb belt of the steel ball. If there is a problem with the steel ball, the shock absorber should be replaced, so the lubrication pin oil must be replenished regularly.

Secondly, if the balance bar is loose, it will make a sound. Glue for the balance bar is used to hold the balance bar. The equalizer bar is just below the front suspension chassis and is an important part that connects the left and right frames.

At this time, we can check whether the glue of the balance bar is loose or damaged. Generally, this is the case with older vehicles. Once it appears, it must be replaced in time, which will affect the stability of the car when driving.

In addition, if the tires of the car are too wide, it will produce abnormal noise. During driving, the temperature of the tires gradually rises, and it becomes easy to circle during intense driving. This situation is not a big problem.

The problem of abnormal noise in the car is big and small, so once the abnormal noise is found, we must find out the abnormal noise as soon as possible, and then decide whether it can be solved, don't be careless.

The reasons for the abnormal sound of the car turning: 1. The problem of abnormal steering noise may be the large gap between the rack and pinion of the steering machine, or the large gap of the universal transmission device, and it is necessary to listen to the sound to judge; 2. This abnormal noise may also be related to the pressure bearing of the shock absorber. The damage to the pressure bearing is mainly related to driving habits, and you should pay attention to the following points in future driving.

Avoid turning the steering wheel on the spot, and try to redirect after the vehicle has moved; 3. When the vehicle is stopped, the steering wheel should be returned to the center position to avoid the suspension system and tires from bearing load. When you need to make a U-turn, try to avoid hitting the steering wheel to the dead center. It is recommended that you go to the 4S store for an inspection, confirm the cause of the fault, and troubleshoot the fault in time.

Regarding the landlord's concern about "what is the reason for the abnormal sound of the car turning?" "Here's my personal opinion:
