A modern car is literally "stuffed" with various additional systems aimed at improving comfort. We can no longer imagine a car without air conditioning, heated seats, power windows and, of course, a hydraulic power steering. Abbreviated as GUR. However, during operation, this mechanism may fail.
An occasion to seriously think if the power steering booms when turning the steering wheel in place. What can these unpleasant sounds testify to? Why is the power steering buzzing when turning the steering wheel? How to deal with this, consider this article.
Characteristic
The hydraulic booster is a steering element . Unlike mechanical type systems, in this case, additional force is generated to turn the wheels, based on a hydraulic drive.
The device works from a crankshaft pulley. The performance of the amplifier is proportional to the speed of this pulley. That is, the greater the speed, the easier it is to turn the steering wheel (which contradicts the real requirements). In this regard, more expensive cars are equipped with electric assistants. They allow you to reduce the gain when the car is typing speed and vice versa.
Working fluid
Those who have a hydraulic booster know that the main component in it (in addition to the pump) is liquid. Oil in the GUR system also has its own resource. No need to think that it is flooded for the entire period of operation. The fluid must be periodically refilled or completely changed. The latter option is more reasonable in terms of system maintenance.
How often do you change a little in a hydraulic booster system? Many manufacturers this figure is not regulated. However, experts say that the oil needs to be changed at least once every 5 years. Every 60 thousand kilometers, a check of the liquid level in the tank should be carried out. If you do not adhere to these rules, a booster of the amplifier is possible when turning the steering wheel.How to determine the condition of the fluid?
Look in the tank. The power steering fluid should have its original color (usually painted red), without impurities and deposits.
There should also be no dirt on the walls of the tank. An important point - when adding oil, do not mix products from different manufacturers. If you do not know which liquid was previously filled, it is recommended to change it whole. Old oil will not be pumped well. Over time, the steering speed will become tight, and the pump itself will begin to make a characteristic sound. But this is not the only reason why the power steering buzzes when turning the steering wheel.
Rail
In modern cars, the worm and helical steering gear are no longer used . All cars are now equipped with rails. Mitsubishi Lancer 9 was no exception. Power steering booms when turning the steering wheel sometimes because of the rail. What is the reason for this?
The problem is the temperature differences and the reagents that the roads sprinkle in winter. This problem is especially relevant for residents of large cities such as Moscow and St. Petersburg. Salt enters rubber anthers and reiki oil seal. As a result, they “tan”, crack, and the steering gear begins to flow. After a short stay, you will find that an oil puddle has formed under the machine.
This is the fluid of the hydraulic booster. Also, the problem is accompanied by a hum. After all, the oil level in the tank is gradually falling. If you do not check this in time, you can ruin the pump. If the power steering booms violently when turning the steering wheel and the fluid often disappears, first of all, examine the condition of the anthers. The rail should be dry., . . , , .

Adjust the position of the tension roller. Typically, a key of 14 is used for this operation. Also check the condition of the belt itself. Of course, when it breaks, the valves will not bend, as on the timing. The pump simply stops generating pressure. However, you should not ride with a cracked belt. If the element has scuffs and small cracks, it needs to be replaced. At the same time, check the condition of the other belts (generator and gas distribution mechanism) that are nearby.Check how the belt bearing rotates: it should not whistle. If so, replace the item with a new one.Pump
And the last reason why power steering is buzzing when turning the steering wheel is a faulty pump. This is due to ignoring oil change regulations and improper steering operation.
The element changes entirely, without repair kits. The pump is the most expensive part (with the exception of the rack) in the car's control system. Therefore, you need to know how to properly operate a car with power steering.How to save power steering?
There are a number of rules that should be followed when operating a car with power steering:
- Do not park your car with the wheels turned upside down, especially in winter.
- Do not overheat the power steering fluid. To do this, do not twist the steering wheel until it stops. Leave a small gap of 5-10 degrees. The load on the pump will decrease significantly, and the liquid will not boil.
- Check the oil level in the tank. If fluid begins to drain, check the condition of the rail and rubber tubes. Leak should be fixed.
- Change the hydraulic oil regularly. This will save the pump and rail from premature failure.
