The car pulls to the left: the reasons. Adjustment of camber-convergence

Each driver's question about the quality and correct operation of the car is always on the first place. If it concerns steering and its performance, then here it is necessary to be especially careful and to be cautious. Steering is one of the most important parts of any car. If the machine pulls to the left, the causes of the problem must be immediately identified and eliminated. This can save from unforeseen situations. Let's look at why a car departs from a straight course.

It should be noted that the reasons for driving the car to the side can be practically there and they will not have to search for them for a long time. But it also happens in a different way.

Why does the car get off course?

There are several typical faults that can cause the car to move to the right or to the left. And not always to blame the road, or rather their condition. The most popular reasons are:

• Alignment-convergence;
• tire pressure;
• Backlash in the steering;
• Condition of rubber.

Below, we will consider it in more detail.

Backlash in the steering

If the car pulls to the left, the reasons can be in the backlash of the steering. Naturally, small fluctuations are allowed. However, they must always be within the limits specified by the manufacturer. If the backlash has increased, then this explains the car's departure to the side. It is enough to remove it, and the problem will be solved. Often these are worn-out steering rods and swivel fists.

Offset of the rear wheels

If the rear wheels are offset relative to the body of the car, this will also entail a situation when pulling the steering wheel to the left when driving. Often this happens after a poor-quality or incorrect adjustment of the camber-toe of the wheels. What to do in this situation? Experts recommend to regroup the collapse and convergence. It is worth noting that the rear wheels are not regulated on all cars.

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

Rear wheel angle position

Here's another situation when the car pulls to the left. The reasons are the collapse of the rear wheels. Sometimes the calibration is broken. If there is a big difference between the camber angles on the pair of rear discs, then the steering wheel will definitely take away. This happens when one of the wheels has a negative angle, and the other - a positive one.

Pressure in the wheels

If the tires are inflated unevenly, this is another possible reason for driving the car to the side. It is worth checking the pressure in all wheels. If the car leaves the straight course, then first check the pressure in the wheels on the side where the car goes. At a difference between tires at least in 0,5 atmospheres the car necessarily will leave a course. To eliminate the cause it is enough to pump the wheels so that they have the same level.

Condition of tires

A common case is various tire defects. So, on cars (including new ones), the tire wears off unevenly. Therefore, the steering mechanism is unstable.

Also, during the operation of the car, deformations of the metal frame of tires can occur when driving on bad roads with low pressure. At the same time, there will be no characteristic beating in the steering wheel. But the withdrawal of the machine from the course is immediately apparent.

There are also situations where a narrow part of the cord layer in the tire is torn. Most often, such disruptions happen when the car moves along uneven roads at low pressure in the wheels. As a result - the formation of a thin strip opposite the side of the disk inside or outside the tire. It is necessary to check the condition of each tire. If there is a serious wheel defect or rubber wear, you can solve the problem by replacing tires. But this does not always work, because the prices for rubber are large enough, and this is a serious purchase. In this case, experts recommend trying to deploy old tires in another row. Then the smooth side will be outside. Inside will leave the one that is worse. So you can solve the problem of leaving the machine aside, and save a serious amount. But it is worth noting that on some tires the protector is asymmetric. In this case, you can try to make a second break and ride until the protector is erased as evenly as possible. Usually it takes from 1 to 2 thousand kilometers.

But of course, if the wear of rubber is large, a simple rearrangement will not last for a long time, and after a while the situation may recur or the rubber can be completely worn out.

Running wheels

When driving on bad roads on tires with low pressure or vice versa, radial or diagonal beats appear. This is also one of the possible reasons for leaving the car off course.

Also one of the common reasons is a violation of wheel balancing. At diagonal or radial beats of wheel disks the car too will leave in one of the parties. The same will happen if the wheels are incorrectly assembled or incorrectly fixed.

Unknown causes

Unfortunately, even experienced diagnosticians sometimes can not determine what happened and why the machine behaves this way. The matter is that even serious companies at a stage of manufacture of cars suppose various various insignificant defects. Some of them can be detected during the maintenance process, but the rest can not be identified. Defects associated with the drive of the car to the side, helps to solve the adjustment of the camber-toe. This procedure costs about 500 rubles. But if the car pulls to the left, and the collapse is normal, then what's the reason? Also note that this problem can be observed with bent suspension levers. The car was in an accident or fell into a large pit at a speed.

The car leaves at dispersal

Front-wheel-drive cars can go to the side if so-called spacers are installed on the front springs. In this case, pull the steering wheel in the direction where the drive is longer. The semi-axis works at a certain angle, and on a longer drive the centrifugal force will be higher. That's why the car pulls to the left when overclocking.

On domestic cars of the VAZ brand, the situation when the car departs from the course is laid down during the manufacturing process by default. Influence on this can only be done by replacing the longitudinal inclination of the shock absorber.

Rubber and alignment

The car owner changes the rubber, then the alignment is adjusted. As a result, the car still leaves, but after all, before installing new tires and adjusting the angles, everything was fine. What's the matter?

The reason is that earlier withdrawal, which created tires, was compensated for by the wrong angles of the collapse-convergence. After adjustment of this equilibrium is no more. Hence the problem. That's why the car pulls to the left after changing the wheels.

Experts recommend to check how the tires affect the withdrawal of the machine. To do this, change the front wheels. If, together with the tires, the car starts to go to the other side, then the causes of the faults are directly related to them. You can solve the problem by installing one of the front tires on the contrary - so that the interior part now becomes external. If mounted rubber is installed, then the wheels are temporarily swapped to make sure that it's rubber. If the car pulls to the left after replacing the wheels, then the front set back, and then they are engaged in finding a pair on which the machine will go on a straight course. This problem now began to occur especially often on domestic tires. The whole thing is in the quality of production - you can observe various disruptions in the rubber carcass, which causes deformations.

If the chassis has been diagnosed and the car pulls to the left, the reasons may be hiding in that only the front axle of the machine has been adjusted. It is necessary to make sure that the rear axle is also good. But more often it happens differently - there are deformed parts on the rear axle. Sometimes even specialists in the regulation of camber can not notice these defects.

Why in the course of operation the installation angles are violated

Probably, every car owner noticed that over time the car changes its behavior. So, even if the car did not get into an accident, if the owner drove very carefully, sooner or later the car will start to move away from the straight-line movement.

This happens because of the subsidence of the elastic parts in the suspension mechanism. These are springs, rubber bands, body parts. Also, over time, gaps appear in the hinged joints in the suspension. When these gaps fold, a very noticeable change in angles is formed.

Also the angle changes due to the aging of the car body. He experiences a bending and twisting moment. This leads to the fact that gradually the geometry changes, and the angles of the collapse-convergence increase. As a result - on the move pulls the car to the left or to the right.

Features of setting the angle of the wheels

If the car is correctly adjusted the camber angle, this will ensure the machine reliable grip with the roadway, as well as stability in the control process. If this parameter is adjusted incorrectly or not configured at all, then this entails a lot of problems, one of which is violation of control. What is the collapse? This is the angle between the perpendicular to the roadway and the center plane on the wheel. The parameter is measured in degrees, and the wheel must be straight. If the camber angle is zero, the wheel will be in a vertical position on the road. With positive collapse, the top of the wheel is deflected outwards, if the collapse is negative, then the wheel is tilted inward.

The most critical angle of wheel installation is the angle of convergence. If it is too positive or negative, this leads to excessive wear of the rubber. The convergence refers to the difference in distances measured on the front, as well as the rear points of the wheel on the horizontal plane. This value is calculated in millimeters. If the distances along the front points are less than the distances, then the convergence is positive. If on the contrary, then the negative. Zero is considered to be a convergence if the wheels are installed in parallel. This is the most correct parameter.

Conclusion

So, we found out why pulls the steering wheel to the left. As you can see, the collapse-convergence is only one of the reasons that the car can drive to the side when driving, accelerating or braking. Much more often the car leaves from straightness because of a condition of tires, wheels, rubber. If the controllability is broken, then it is worthwhile to walk through for all possible reasons and eliminate the detected malfunctions. And the adjustment of the camber-toe will make driving easier and more pleasant.
