I recently flew into the pit and bent the disc. At the service station everything was leveled for me. But he noticed that the car continues to drive to the left. What could it be? Do I need to go back to the service station and repair the chassis? Visit this link to gain more ideas: How Long Do Brake Pads Last?
Clearly, after an impact, in which the disc bends, the geometry of the undercarriage cannot remain the same. The wheel alignment angles, including the camber and toe angles, are set with an accuracy of minutes (60 minutes in one degree). Serious damage to the suspension elements sufficiently changes the required parameters of these angles. As a result, the wheels of such a car roll in “different directions”, affecting the direction of movement of the entire car. In other words, the car is being pulled aside. Naturally, such a drift is an obvious indicator of the need to visit the service station in order to search for possible damage and chassis malfunctions.
It is possible that the suspension arm is bent, and in the worst case, other elements. The saddest option is the deformation of the subframe, body elements, frame. A simple replacement of one small element within an hour or two is no longer enough. The best option is the absence of damage and the need to adjust the wheel alignment angles. In this case, a couple of hundred hryvnias and forty minutes of time solve the problem completely.
The shock absorber, like any part of the car, is subject to wear. But if, for example, problems in the engine give themselves away by a change in the "voice" of the engine, the color of the exhaust and the increased consumption of gasoline, then many drivers do not notice damages of the shock absorbers for a long time. But not only the car body suffers from worn out shock absorbers, but also the safety of the driver and passengers.
During normal operation of the car, without jumping from a springboard and falling into open wells, shock absorbers serve faithfully for 120-150 thousand km. But they can be “killed” much earlier. The lifespan of shock absorbers depends on the driver's driving style and road conditions.
The easiest way to identify wear of shock absorbers when visiting a service station. But you can carry out the inspection yourself. Examine the shock absorbers carefully (you can do this from any garage pit or even lie under the car). A serviceable shock absorber is dry - only the formation of the so-called oil "mist" is allowed. But in no case should there be obvious drips! It is possible to accurately determine the condition of the shock absorbers by driving the car along a bumpy road. Working shock absorbers after such a charge should warm up well.
If the service station really checked everything qualitatively and did not find anything, and the symptoms are obvious, the solution is simple - go to another service station. You should start troubleshooting with the diagnosis of the chassis, first checking all connections, both movable and fixed, for the presence of backlash.
Always check brake discs and pads for acceptable wear and seizure. It is imperative to measure the pressure in the tires, make balancing, pay attention to the uniform wear of the tire tread, the presence of visible damage. All this gives vibration to the steering wheel. Use the vehicle with extreme caution until the fault is found.
