Why is there a knock when turning the rudder to the right, to the left?

At the first stage of owning a private vehicle, the owner is mainly focused on the traffic situation. Over time, the comprehension of certain features of his car comes. There is the possibility of self-diagnosis of car breakdowns (there was a knock when turning the rudder, for example).

Self-diagnosis: easy to master

This comes, of course, not immediately, but with the acquisition of experience, a person who has a minimal propensity for technology, can quite determine a number of regular breakdowns of his car. To some extent, the skill of self-diagnosis is due to the high cost of maintenance, and sometimes incompetence of specialized personnel in the service station.

What is typical, the ability to correctly determine the breakdown of the machine is useful to you in any case, regardless of the selected autobrand. First of all, the chassis of the car suffers - most often because of bad roads. We will try to understand the reasons for the rapid deterioration of the running gear of popular brands today. We will describe possible variants of their breakdowns, we will learn to diagnose by symptoms (knocking on the steering wheel when turning, for example), and also consider options for rapid maintenance and prevention of their "iron horses".

Domestic - does not mean bad

It's no secret that today the most popular cars are the so-called consumer class. A rather large segment of sales in this sector is the domestic auto industry. As a rule, a consumer who buys such a car is guided by the manufacturer's affordable pricing policy, with quality almost up to world standards. And that's why we see more and more in our streets new "Lada", in which we do not even recognize the familiar features from childhood.

In the new "Grandes", "Priora" and "Kalinas" are embodied almost all the modern innovations available for cars of such a modest class. But are they reliable? The last generation of VAZs, the famous "eight", "nine" and "tens" quite often lost in reliability and adaptability to our roads, even foreign-made cars of the old model. They were bought anyway because of the modest price, but still considered more as a temporary component of their lives, hoping in the near future to switch to more comfortable and reliable cars of Western or Asian production.

As already noted, most often in modern road realities the chassis of the car breaks down. Is it reliable in modern VAZs? The answer is unequivocal: yes. Engineers and designers have tried to make life easier for the modern driver.

Repair is expensive

However, the use of innovation and increased reliability have the reverse side of the coin. Modern mechanisms are much more difficult to repair (and it's not just about technology, but about money). And although the repair of the "running" VAZ, of course, can not be compared with the repair of a similar western product, but there was no trace of the former cheapness.

Proceeding from this sad fact, the financial risks of a modern driver who has chosen a product of a domestic manufacturer or an imported car vary considerably. Consequently, the value of self-diagnosis of auto failures has increased substantially, at least as widespread as a knock on the steering wheel when turning.

Knocks in the steering wheel - what to do?

Believe me, if you clearly define what is faulty in your car, you will spend a lot less money on STO. The reason is trivial: you do not have to pay for what you do not need (but what can try to impose on the SRT).

So, let's consider the situation. You went to the sea (to the mountains, beyond the city - it is not important) and heard a knock when turning the rudder ("Priora" is your relatively new!) Do not rush to immediately go to the service. Try to understand the problem yourself. The set of regular and not regular situations for such breakdowns is rather limited.

Let's consider the main options. The most frequent critical situations are associated with the steering mechanism. The first thing to determine is the nature of the knock. It can be "plastic" and "metal".

Plastic defense loosened

If, with a sharp turn of the steering wheel, a knock is similar to the friction of plastic, almost 100% of the car is fine. As a rule, such sounds are produced by poorly fitted wing protection. When you turn out the front wheels very often we touch and slightly deform the plastic locker. It is he who publishes such unpleasant but quite safe sounds.

But do not pay any attention to this at all. The fact that the plastic protection is attached directly to the "skirt" of the front bumper. And if it completely deforms, it is possible that one day at the next turn you just rip it (and at the same time damage the bumper). Therefore, it is better not to rely on "maybe", but to fit the defense.

When the parts are to be replaced

The situation is much more serious if the knock when turning the rudder is more like a metallic crackle or grinding. This means that in the near future you will have substantial financial expenses. And in order to reduce them, you need to figure out the reasons yourself.

When there is a "gurgling" knock when turning the rudder, the simplest explanation for this is the wear of the tips of the steering rods. A rather unpleasant, demanding phenomenon. After all, if the process of wear and tear continues, the entire steering mechanism may be destroyed, and as a result - expensive repairs, and maybe even an emergency on the road. Fixing is not very costly, although the tips usually change in pairs - on both sides of the car. The main difficulty lies in the subsequent work on the collapse-convergence.

Another fairly common problem is when there is a knock when turning the rudder ("Kalina" or "Priora" are susceptible to this "sore"), is associated with the wear of the bearing of the upper support of the shock absorber rack. The disease is unpleasant, but quite easily eliminated. The bearing itself is not very expensive, and the work to replace it will not take long.

From the burst spring to the replacement of shock absorbers

A rather unpleasant knock when turning the rudder produces bursting springs. Repair is associated with the analysis of the front pillars and, as a consequence, possible replacement of the same bearing of the upper support. It should be noted that in the case of an incorrect diagnosis or other reason why you can not carry out this repair, the consequences for you will be very serious. The broken spring can not take on that part of the load, which it experiences in the vertical swing of the car. In this regard, there is an additional impact on the shock absorber strut, which can lead to a breakdown. But this is a full-fledged repair of the front running your car. It is not difficult to calculate the financial losses in this case. You will have to buy not only new springs, but also new shock absorbers, which in most cases change in pairs.

If a knock when turning the rudder to the right or to the left is accompanied by a buzz, this is a direct consequence of the failure of the bearing of the front wheel hub. It's sad. The difficulty of repair is to press out the old bearing from the hub (a very long and expensive operation). Such a breakdown can be "lethal" for all front and all-wheel drive cars. In case of complete wear of the bearing of the hub, the front suspension may be destroyed and - God forbid, of course! - emergency on the road.

How to diagnose the wear of the joint

Let's move on to the main and most serious noise that you can hear: knocking when turning the rudder ("Kalina" it or "Priora" - it does not matter) in one direction or another. Metal crash when the steering wheel is completely turned off testifies to the failure of the SHRUS, or, as it is still called in the people, "grenades". When the crackling is heard from the right and left, this means that both your "grenades" are to be replaced. If, when turning the rudder to the left, a knock is heard from the same side, you know exactly which part is more worn out.

The situation with the failure of the CV joints, as a rule, is connected with the spoilage of the rubber anther, which protects the metal case of this mechanism. Even a small gap can lead to the replacement of one of the most expensive knots in the running of your machine. Therefore, once a month it is better to check the anthers of both "grenades" for damage.

Monthly noise prevention

Noises and cracks in VAZs can arise due to the weakening of numerous threaded connections. These are easily diagnosed moments and just as easily removable. The main thing is not to panic, but to call on a good lift or "pit" in the garage. Then, armed with a wrench of the right size, just pull up all the loose and pounding connections, including the wheels of your car.

Foreign brand does not guarantee the absence of breakdowns

The situations described above are typical not only for Russian cars. In principle, an expensive foreign car is not insured against this. The whole question is how often this will happen.

As already noted, the quality of cars produced in Russia has significantly improved. This applies to both truly Russian VAZs and cars produced under license. The percentage of factory marriage is significantly reduced: knocking when turning the rudder ("Logan", for example, is going to in Russia) will not appear immediately. And it is quite possible to avoid such situations. Experts advise to pass every six months necessary diagnostics on specialized service stations, not leading up to the notorious "knocking and banging" in running gear.

In addition, given not always high-quality road surface, it is necessary to comply with the speed limits and take security measures to cross difficult or simply bad areas. If these simple recommendations are followed, your machine will last you for years without any breakdowns, and funds that are not spent on repairing vehicles can be used for anything else.
