7 Causes of Unexpected Power Steering Noise: What to Look for and How to Fix?
Some parts and assemblies in the car have greater reliability because the life of the parts in the vehicle depends on their performance and reliability. These mechanisms include the power steering. However, nothing lasts forever, and sooner or later it breaks. This creates noise in the power steering. What becomes their cause and how to act, having heard them when turning the steering wheel, the AvtoVzglyad portal found out.

Power steering is a very patient unit in a car, but you shouldn’t abuse it. Otherwise, he will just buzz, or even howl, to notify the vehicle owner that he needs maintenance or even repair. So what causes strange noises during power steering operation?

One of the reasons for the appearance of an annoying hum in the power steering is to air the system. How is this possible? Easier than you can imagine. For example, air may appear in the working fluid due to microcracks in the supply hoses and nozzles. Cracks can be so microscopic that no liquid flows out, but air enters the system, as they say, with a bang!

Another reason could be the lack of a power steering reservoir cap. They forgot to put it in, unscrew it or get lost somewhere along the way, with the engine running, and now the air is already in the system.

Also, the cause of the appearance of air bubbles in the power steering fluid can be a damaged engine circuit, or the fluid itself has not been changed for a long time, is contaminated or has not been selected in accordance with the car manufacturer’s recommendations . As a result, it may foam when pumped. And this situation must be corrected immediately.

However, not only airing the power steering can cause hum. For example, an insufficient liquid level in the tank can cause parasitic noises. In this case, of course, one must look for a place in the system from which the liquid leaves it. After elimination, the liquid is added to the desired level.

Another cause of buzzing can be a broken steering rack. To restore normal operation of the hydraulic booster, it is necessary to eliminate the malfunction.

Insufficient tension of the drive belt or its complete wear will also cause a hum. In the first case, a simple belt tightening may be the solution. Second, its complete replacement.

If the pump is faulty in the system, it is very easy to spot the malfunction, not only from the hum, but also how difficult it becomes to turn the steering wheel. In this case, the pump must be replaced with a new one.

However, we remember that the power steering performance and mileage is very high. And if you follow simple rules while using it, the system will last a long time, not only for you, but also for whoever your car will pass to when the time comes. For example, do not hold the steering wheel in extreme positions for more than 10 seconds and turn it all the way. The pump cannot tolerate such abuse.

Also, do not leave the car in the parking lot with the wheels turned. The next time the engine is started, the power steering pump is also heavily loaded. You don’t need to leave the wheels turned unless of course you parked it on a slope and have problems with the parking brake.

Look at the car and listen to it. And if you notice something strange in the operation of its systems, it is better to find out immediately. “Later” may be too late.
