The modern car is literally "stuffed"various additional systems aimed at improving comfort. We can no longer imagine a car without an air conditioner, heated seats, electric windows and, of course, a hydraulic power steering. In short, it is called the GUR. However, this mechanism may malfunction during operation.
Reason to think seriously if the HUR buzzes whenturning the steering wheel in place. What can these unpleasant sounds indicate? Why is the steering wheel buzzing when turning the rudder? How to deal with this, we consider in this article.
The hydraulic amplifier is asteering element. Unlike mechanical systems, in this case, an additional force is created to turn the wheels, based on the hydraulic drive.
Those who have a hydraulic amplifier know,that the main component in it (besides the pump) is a liquid. Oil in the GUR system also has its own resource. It is not necessary to think that it is flooded for the entire lifetime. The liquid must be periodically topped up or changed completely. The latter option is more reasonable, in terms of system maintenance.
How to determine the state of the fluid?
Look in the tank. The fluid of the hydraulic booster must have its original color (usually painted in red shade), without impurities and deposits.
In modern cars is no longer usedworm and screw steering gear. All cars are now manned with racks. "Mitsubishi Lancer 9" was not an exception. Humming GUR when turning the steering wheel sometimes because of the reiki. What is the reason for this phenomenon?
The problem lies in the temperature differences andreagents, which in winter roads are sprinkled. Especially this problem is relevant for residents of large cities, such as Moscow and St. Petersburg. The salt falls on the rubber anthers and the stuffing box seal. As a result, they "dub", crack, and the steering gear begins to flow. After a brief parking you will find that an oil puddle has formed under the car.
If the problem was detected on time, everything is decidedby replacing a damaged anther or stuffing box. After this repair, the liquid stops flowing outward. In neglected cases, if the HUR buzzes when turning the rudder to the stop, the rack mechanism changes entirely.
The next reason is the drive mechanism.The hydraulic amplifier is driven by the crankshaft pulley. The nodes are connected by belt transmission. It should have a good fit. Otherwise, the pump pressure will be insufficient. In addition to the rumble, you will feel that the steering wheel is turning much tighter, in addition there will be an increased vibration. Check the condition of the belt.
And the last reason that the HUR buzzes when turning the rudder is a faulty pump. This is due to ignoring the oil change regulations and improper operation of the steering.
How to save GUR?
There are a number of rules that should be followed when operating a car with a GUR:
- Do not leave the car in a parking lot with turned-out wheels, especially in winter.
- Do not overheat the fluid in the power steering. To do this, do not wring the wheel until it stops. Leave a small gap of 5-10 degrees. The load on the pump will decrease many times, and the liquid will not boil.
- Observe the oil level in the reservoir. If the liquid begins to go away, check the condition of the rail and rubber tubes. The leak must be eliminated.
- Regularly change the hydraulic oil. This will save the pump and rack from premature failure.
- Do not drive with a weakened strap. With any extraneous sounds from under the hood (often a characteristic whistle), check the tension level.
So, we have found out, for what reasons is booming GURwhen turning the steering wheel and how to prevent this malfunction. The hydraulic amplifier makes it easier to drive, especially with parking maneuvers. However, do not forget that the GUR is a separate mechanism, which uses its own oil and its drive. With proper care, this unit will please the driver with a long and quiet operation.
