Which ball joint will last longer?

Ball joint was developed long before the appearance of the first car. In simple terms, it is a hinge that rotates in all planes. To its drawbacks can be attributed the limited course, as well as some fragility. It, as a rule, becomes the reason of a poor-quality material. Unfortunately, this also concerns the domestic auto industry. Often on the box, up to 30 000 - 40 000 resources are declared, but the ball joint starts to knock after a couple of thousand.

In addition, you can not blame one particular manufacturer, since the products of the same company differ significantly in the results shown. The classic independent front suspension uses two ball bearings on each side. They provide the course of the suspension and serve to ensure that the wheels can turn. It is worth remembering that this scheme is applicable only for independent suspension, because when using a transverse beam, the ball is replaced with pivots.

The ball joint is the most vulnerable "organ" of the front suspension, even the shock absorbers have a longer service life. By the way, wear of the first significantly reduces it. And not only him, but this, all rubber products, which are used in the suspension, suffer. So to monitor their condition is mandatory. Unfortunately, as long as the spherical support does not knock, it can not be diagnosed without disassembly, which, in fact, hinders.

But you should not postpone it just because "a good knock should show itself." This means that it can fly out at the most inopportune moment. Well, if it happens in summer in the village and at low speed. Even under such conditions bruises are unavoidable. The lower ball joint suffers the most, because it accounts for almost the entire mass of the car. When it falls into the pit, it is unloaded, and under the action of the spring, it is "pulled out" in the opposite direction.

Such a scenario sooner or later causes wear, because an anvil effect occurs, which not every steel grade can withstand. Unfortunately, modern manufacturers negligently concern this aspect of production, which leads to premature failure. Ball joint VAZ costs, as a rule, 300 rubles, replacement of all will cost in 1200, besides, that you will have to perform the work yourself. And it's nerves, time, maybe even trauma. If you take into account the resource of work, then they have to be changed twice per season, depending on the operating modes.

I want to dispel the myth that ball bearings wear only on domestic cars. The fact is that most of the parts are manufactured under license, which means that they can be manufactured in Russia or abroad. For example, in France there is a factory that supplies spare parts for "classics", in addition, they are produced for another 27 brands of the world. Quality does not depend on the brand of the car, not on the manufacturer, not on the country in which the plant stands, but on the metal from which this or that spare part is made. To use most of them, this is the most important factor. But everyone has his own opinion.
