The car pulls to the left: causes. Adjustment of wheel alignment

Each driver question the quality and proper operation of the vehicle in the first place. When it comes to steering and its efficiency, there is a need to be especially careful and exercise caution. Steering – one of the most important parts of any car. If the car pulls to the left, the cause of the problem must be urgently identified and removed. This can save you from unforeseen situations. Let's look at why the car leaves the straight course.

It Should be noted that the causes of vehicle drift to the side can be almost near and long to find them is not necessary. But it happens the other way.

Why the car drives of the course?

There are a few typical faults that can cause the vehicle pulls to the right or to the left. Don't always blame the road, but rather their condition. The most popular reason –

• Alignment;
• Tire pressure;
• Backlash in the steering;
• Rubber.

Below we describe everything in more detail.

Looseness in steering

If the car pulls to the left, the reasons can be loose steering. Of course, small fluctuations are allowed. However, they have to be in the normal range, which is specified by the manufacturer. If the backlash has increased, then this explains the withdrawal of the car aside. Remove it and the problem will be solved. It is often worn tie rods and steering knuckles.

The Offset of the rear wheels

If the rear wheels offset relative to the vehicle body, it will also entail a situation where the steering wheel pulls to the left when driving. This often happens after a poor or incorrect configuration the alignment of the wheels. What to do in this situation? Experts recommend re-adjust the camber and toe-in. It should be noted that the rear wheels are governed not on all cars.

You should Also diagnose and, if necessary, to adjust the position of the front wheels to the rear. If there is a violation of geometry, after eliminating the problem, the car will go right.

The position of the angle of the rear wheels

Here is another situation where the car pulls to the left. The key reason is the collapse of the rear wheels. Sometimes disturbed the calibration. If there is a big difference between the camber angles in a pair of rear discs, then the wheel will necessarily lead. This happens when one of the wheels has a negative angle and the other – positive.

Tire Pressure

If the tires are unevenly inflated, this is another possible cause of vehicle drift to the side. You should check the pressure in all four wheels. If the car goes with the straight course, the first thing to check tire pressure on the side where the car goes. If the difference between the tires of at least 0.5 atmospheres, the car will go off course. To troubleshoot the cause enough to pump up the wheels so that they were of the same level.

Tyres

It is Often the case – different tire defects. So, on motor cars (including new) tyre wears unevenly. Therefore, the steering becomes unstable.

Also in the process of operation of the vehicle possible deformation of the metal framework of the tyres when driving on bad roads at low pressure. Thus the characteristic wobbling in the steering wheel will not. But the withdrawal machine of course appear immediately.

There Are situations when breaks the narrow part of the cord layer in the tire. Most of these tears happen when the car is driven on rough roads at low pressure in the wheels. As a result – the formation of a thin strip of the opposite side of the disc inside or the outside of the tire. You Need to check the condition of each tire. If there is a serious defect in the wheels or tire wear, you can solve the problem of replacing the tires. But it doesn't always work, as the price of rubber is large, and this is a serious purchase. In this case, experts recommend to try to deploy an old tire in the other direction. Then the smooth side will be on the outside. Go inside the one that is worse. So it is possible to solve the problem of leaving cars aside, and to save a substantial amount. But it is worth noting that some tire tread is asymmetrical. In this case, you can try to re-collapse and ride until the tread wear out evenly. Usually it takes from 1 to 2 thousand kilometers.

But of course, if the tire wear large, simple rearrangement will not last long, and after a time the situation could be repeated, or the rubber will wear out completely.

The runout of the wheels

When driving on bad roads tyres with low pressure or Vice versa appear radial or diagonal beating. It is also one of the possible causes of car care.

Also one of the common causes – violation of the balancing of the wheel. In case of diagonal or radial wobbling of wheels of cars, too, will leave to one side. This is what happens when the wheels incorrectly assembled or incorrectly applied.

Unknown cause

Unfortunately, even experienced diagnosticians are sometimes unable to determine what happened and why the machine behaves. The fact that evenmajor companies in the production phase of the vehicles allow for different defects. Some of them can be detected in the process of conducting IT, but the rest can not be identified. The defects associated with the withdrawal of the automobile aside, helps to solve the adjustment of wheel alignment. This procedure costs about 500 rubles. But if the car pulls to the left, and the collapse of normal, why? Also note that this problem can occur when the bent control arm. The car has been in an accident or were in a major hole at speed.

Car gets during acceleration

A front wheel drive car can go in side if the front springs installed with so-called spacers. At the same time pull the wheel be to the side where the longer drive. The axle shaft runs at a certain angle, and the longer the drive the centrifugal force will be higher. That's why the car pulls left under acceleration.

On domestic cars VAZ, the situation when the car goes off course, inherent in the manufacturing process by default. Influence is possible only by replacing the longitudinal inclination of the struts.

Rubber and alignment

The car Owner to change tires, then you can adjust the alignment. In the end the car still goes, but before installing the new tires and setting angles everything was fine. What's the matter?

The Reason is that earlier withdrawal, which caused the tires, compensated for by the incorrect angles of alignment. After setting this equilibrium is no more. Hence the problem. That's why the car pulls to the left after changing wheels.

Experts recommend to check how the tires affect the slip of the machine. To do this, swap the front wheels. If with tires the car will begin to go the other way, then the causes of the faults are directly related to them. You can solve the problem installing one of the front tires the opposite – so that the inner part has now become external. If set to sent tires, then the wheels temporarily change places in order to make sure the case in rubber. If the car pulls to the left after replacing the wheels, then the front set back, and then do a search of such a pair where the car will go flat rate. This problem now began to meet often, especially for domestic rubber. It's all in the quality of production – can see the violation of the frame of the rubber, which leads to deformation.

If the chassis was inspected, and the car pulls to the left, the reasons can hide in that has been adjusted only the front axle of the machine. Ensure that the rear axle is also doing well. But often it is otherwise – at the rear axle has deformed parts. Sometimes even the experts to adjust the camber may not notice these defects.

Why in the process of operation violated the corners of the installation

Probably every car owner noticed that over time the car changes its behavior. So, even if the car hasn't been in an accident, if the owner drove it very carefully, sooner or later the car will start to go in the direction of rectilinear motion.

This Happens because of the subsidence of the elastic parts in the suspension mechanisms. This spring, elastic bands, body parts. Also over time, and accumulate the gaps in the hinge connections in the suspension. When these gaps emerge, then there is a quite noticeable change in angles.

The angle varies due to aging of the car body. He's experiencing bending and torque. This leads to the fact that the geometry changes gradually, and the angles of wheel alignment are increased. As a result, on-the-go pulls the car left or right.

Features of the installation angle position of the wheels

If the car is properly adjusted, the camber angle, it ensure the machine reliable adhesion with the road and stability in the management process. If this parameter is adjusted incorrectly or not configured at all, it entails a lot of problems, one of which – violation of control. What is the collapse? Is the angle between the perpendicular to the road surface and the Central plane of the wheel. The parameter is measured in degrees, the wheel should be straightforward. If the camber angle is zero, the wheel is in a vertical position on the road. With positive camber the top of the wheel is deflected outward, if the camber is negative, then the wheel is tilted inwards.

The Most critical angle of the wheels is the angle of convergence. If it is too positive or negative, this leads to excessive tire wear. A convergence is called the difference of the distances measured by the front and rear points of the wheel on a horizontal plane. This value is calculated in millimeters. If the distances at the front points less than at the rear, the toe is positive. If, on the contrary, it is negative. Zero is considered to be convergence, if the wheels are parallel. This is the most correct option.

Conclusion

So, we figured out why the steering wheel pulls to the left. As can be seen, alignment – this is just one of the reasonswhich car can lead in the direction of motion, acceleration or braking. More often the car goes out of alignment because of the condition of tires, wheels, rubber. If you upset the handling, you should sequentially go through all possible causes and eliminate detected faults. And adjustment of wheel alignment will make driving easier and more pleasant.
