In recent years, everyone who came to us with the problem of vibration (hum) in the power steering system was faced with the purchase of counterfeit high-pressure hoses (not original ones). Many of them replaced more than one set of hoses, and even managed to change the power steering mechanism and power steering pump in search of a problem, and the cost of the components does not always tell us about counterfeit: someone paid 1,100 rubles. for a set of hoses, and for some 2000 rubles. Here are examples of some requests to us:
- Hello! I own a VAZ 21123 car with power steering of your production. The other day I discovered mechanical damage to the steering rack boot, I decided to replace the boot and the high pressure hoses (2110-3408100-20 and 2110-3408018-20). After this, strong vibration and noise appeared when the steering wheel was quickly turned to the left, and sometimes it also occurs when turning right. The high pressure hose vibrates strongly. Sergey K.
-Hello. I'm interested in one question: I have a VAZ 2111 2008. After replacing the high pressure hose, I purchased the hose from a nearby store, the hose was VAZ 2110.2170. When turning the steering wheel, there was a vibration in the body and a strong noise; the car service center recommended purchasing old-style hoses. Roman Sh.
-I bought high pressure hoses with the same markings on both hoses 20MPA 101208 211010010 RS. And when turning left there is a vibration. What did I even buy? Vladimir
-Hello. There is a problem, please tell me what the problem is. 1. A VAZ 21124 car, when driving around a corner in the city at low speeds of 30-40 km/h, vibration is transmitted to the steering wheel (left or right turn, it doesn’t matter) and in the cabin you can hear the sound brrrrr brrrrr brrr. Tell me, what could it be? They checked the steering and ball joints, everything is in order. 2. When you stand still, vibration is transmitted to the body, and if you turn the steering wheel a little, it disappears for 20 seconds, then appears again. Also, when you turn the steering wheel, there is some kind of sound like Uuuuuuu. Could these problems be related to the pump? Vladimir.
These are just a few examples of the hundreds of car enthusiasts who contacted us. The problem with vibration is the absence of a throttle (vibration damper) under the ferrule, which is located in the middle of the high-pressure hose. The power steering pump creates uneven pressure in the system, the throttle is used to equalize this pressure. Many people ask how to distinguish an original high-pressure power steering hose from a counterfeit one, after analyzing the photographs that customers sent us: we found clear differences:
1. In the original NEW SAMPLE hoses, the fitting at the ends of the hose has a triple crimp, and on counterfeit ones it has a double crimp.
2. Since 2015, the plant has been producing NEW SAMPLE high-pressure hoses with yellow braiding, but not counterfeit ones.
3. ROMANIA is stamped on the fitting of the original hose, there is also a paint mark when passing through production quality control, but not on counterfeit ones.
4. The difference is in the stamping of the crimp sleeve in the middle of the hose.
We hope this article will help you understand the causes of car malfunctions and navigate correctly when searching for and purchasing high-pressure power steering hoses, so as not to overpay money and waste your time. Please note that the article discusses NEW SAMPLE hoses, since they are the ones that are most often counterfeited. Many people are interested in the difference between new and old hoses. They are interchangeable; the old-style hoses have a high-pressure tube that is not rolled, so the process of replacing these hoses is less time-consuming and expensive than new-style hoses, the tube of which is rolled, as a result of which it is necessary to remove and install the steering mechanism. Have a good trip!
Driving a car used to be quite a difficult task. The power steering, also known as power steering, of the Lada Priora makes the steering wheel of the car light. The electric booster is even lighter, but not more informative. Priora has configurations with EUR and power steering. The amplifier operates using liquid, so in comparison with an electric amplifier, you need to monitor the level. On Priora, the assembled part will cost more than 7 thousand. The price is for the kit - it consists of 11 parts. Constantly being on the road tires you not only with emotional fatigue, but also with the incessant movement of the steering wheel, gear lever and pressing the pedals. To reduce the load on muscles, various systems are built into cars. Some of them make the pedals “lighter”, while others make it easier to turn the steering wheel.
Standard power steering (hydraulic booster) - article number and price
The standard power steering for the Priora received catalog number 21230340701200, the cost is from 7,500 rubles. Before ordering and purchasing, you should check the availability of fasteners. But the system itself is sold for spare parts:
- Long oil tank strap - 21100341010500 - about 500 rubles.
- Oil tank bracket - 21100341010000 - about 150 rubles.
- Power steering tank - 21230341001000 - about 900 rubles.
- Supply pipe - 21100340812500 - about 1,000 rubles.
- Power steering pump - 21100340700900 - about 6,000 rubles.
- Pillow – 21100340804000 – about 400 rubles.
- Low pressure pipe – 21100340804000 – about 400 rub.
- High pressure hose with tube – 2110034801810 – about 1,900 RUR.
- High pressure pipe – 21100340808001 – about 900 rub.
- Low pressure hose with tube – 21100340802600 – about 1,800 RUR.
- Front high pressure hose – 21100340810010 – about 1600 rub.
Afterword
But in the end, all this torment was not worth it. It’s better to contact the service center and replace the old, broken spare part with a new one.
But if time and money are running out, then you can do like me. You can save money and buy separately only those spare parts that you need, and leave those suitable for use.
Of course, in salons, masters will achieve better results than self-taught drivers. But if hands are not hooks, then why not try?
I hope I helped you, my dear readers. Happy travels!
What does the power steering system consist of and how does it work?
The Priora's power steering works in the steering system. Its main part is the pump. The system fluid circulates in a special tank, pipes, and hoses that can withstand high pressure.
The operation of the hydraulic booster depends on the quality and “purity” of the corresponding working fluid in the system. When the driver turns the steering wheel, the pump increases the pressure of the working fluid, and it pushes the piston, increasing the force on the steering rack. In this case, the force that develops thanks to the pump is proportional to the resistance force that acts on the wheels - be it off-road or on a free track.
It turns out that at high speed the Priora’s hydraulic booster practically does not work - changing lanes or turning requires the least effort. A special torsion bar device, which is part of the steering mechanism, helps to properly distribute the resulting forces. Having received a signal in time that the created pressure is sufficient, the pump stops its operation, and sufficient auxiliary force is created to turn the steering wheel. It turns out that while driving, the driver constantly needs to act on the steering wheel with the same force, because the power steering always minimizes the impact of the opposing force.
Differences between EUR and power steering
These are completely different units. To understand the main differences, it is enough to study the hydraulic booster. Its main component is a pump driven by the crankshaft, it is integrated with other parts. The operating principle of the hydraulic booster is based on hydraulics.
As for the electric power steering, it is driven by an electric motor. Its design also includes an electronic control unit, a steering shaft with a torsion element and sensors. The EUR works according to a different scheme:
- When the steering wheel rotates, the torsion shaft twists;
- Special sensors record changes in the position of the shaft and send data to the electronic control unit;
- After analyzing the information, the unit sends commands to the electric motor;
- As a result, the unit creates the necessary force or facilitates turning the steering wheel.
Car enthusiasts often argue which option is preferable for the “ten”. In fact, power steering is an obsolete unit that is being actively removed from modern passenger cars. The electric booster works even when the engine is turned off and weighs less than the power steering. The main advantage over “hydraulics” is reliability - the electric unit requires virtually no maintenance. There is less load on the engine, and as a result, less fuel is also needed. The EUR is also good for our conditions because it functions well at low temperatures.
But the electric booster also has its drawbacks. Its design is more complex than that of “hydraulics”, hence the high price. Sometimes the electronic control unit sends incorrect commands, this was especially felt by the owners of the first generation Kalina. If you drive for a long time on a poor-quality road surface (or lack thereof), the EUR may turn off for several minutes due to overheating.
Main faults of the hydraulic booster on a Lada Priora car
When operating a Priora with power steering, the following problems may occur:
- When turning the steering wheel, a feedback is felt, similar to a push in the opposite direction (replacing or tightening the drive belt will help);
- It is difficult to turn the steering wheel (replacing or tightening the belt will help; adding fluid to the tank to the normal level, replacing or cleaning the filter; replacing the pump; removing the air lock or adjusting the idle speed);
- The steering is too “smooth” (adding fluid, removing the air lock and checking the steering, changing the tires will help);
- Extraneous noise during operation of the power steering (adding fluid, removing air lock or mechanical damage, checking the pump and replacing it will help);
- The steering wheel vibrates with weak shocks (removing the air lock in the system, balancing the wheels or changing the tires will help).
Repair: removal and installation of power steering Lada Priora
Replacement of Gur Priora and its repair must begin with correct diagnosis. It is also worth inspecting the reservoir of pipes and hoses in order to notice any damage in time. To remove the power steering you will need:
- stopper for retaining rings;
- key 12, head 14, 24;
- new bearing;
- syringe and container for draining liquid;
- fine-grained sandpaper and clean rags.
Working with power steering requires care - the system must remain sealed. The low pressure hose (2110 3408026 – article number) is often damaged. Therefore, the reason for the intrusion into the power steering system is the replacement of the Priora power steering hose. Repair work is carried out as follows:
- Park the car on level ground, tighten the handbrake, remove the negative from the battery.
- Find the hole in the pulley and unscrew the mounting bolt that secures the pump;
- Use a syringe to pump out the oil from the system. At the same time, rotate the steering wheel in different directions so that the liquid comes out of the hoses;
- Loosen the clamp attached to the reservoir hose. Take out the hose;
- Remove the bolt that secures the high pressure hose;
- Remove the bolt and replace it with a metal rod of the same diameter.
- Take out the pump, clean it of dirt, you can clean all the systems connected to it of dirt.
- If repair or replacement of the system is required, after repair, reassemble everything in the reverse order.
Installation of EUR
Required Tools
Let's say you purchased an EUR kit - it could be from a VAZ 2110 or from another model, for example, from a Priora. Prepare the following tools:
- Drill together with a metal drill.
- Set of screwdrivers, grinder.
- Long ruler.
All is ready? Let's move on to installation.
Step-by-step instruction
- You need to remove the standard terminal from the block and place it in the block on the harness. We find the standard drive, which is attached to the block. A free terminal must be installed in its place. Now the wire can be placed between the fasteners.
Adjustment
After assembly, you will need to straighten the steering wheel if it is installed crooked. Separately install the sensor that came with the EUR. If the column casing is cracked, it is better to immediately replace it with a good one. There may be gaps between the front panel and the casing - they must be removed.
Replacing the power steering fluid of a Lada Priora car step by step instructions
To change the power steering fluid of the Priora, it is highly recommended to call a friend and partner. You will have to perform several operations simultaneously. For convenience, it is recommended to place the car in a pit or raise the front of the car on two supports using a jack. Prepare a container to drain the used fluid. Carry out work on replacing the Priora power steering fluid in the following order:
- Secure the car.
- Remove the power steering reservoir cap. Place the syringe into the tank and gradually pump out the liquid accumulated in it. For convenience, before putting the syringe into the tank, it is recommended to put a small hose on it. It is also recommended to cover with a cloth the entire engine compartment over which you will carry the syringe with oil to the container, so as not to pour in excess drops.
- Ask your partner to get into the car and turn the steering wheel. At this time, suck out the liquid that flows into the tank from the hoses.
- But that is not all. To collect the remaining oil, loosen the clamp of the high pressure hose, grab the hose, and lower it into the drain container.
- Ask your partner to turn the steering wheel again.
- Reinstall the hose and tighten the clamp tightly.
- You only need to fill in new fluid. First, fill it almost to the top, and then ask a friend to turn the steering wheel. The fluid level will drop, but this is normal. Add a little more, leaving a few centimeters up to the throat.
- Have someone start the engine for 10-20 seconds and then turn it off. After this, you need to turn the steering wheel again. During this time, the remaining air will leave the system.
- Add oil to the normal level. Screw on the tank cap and close the hood.
- Start the engine. Check if the power steering works as well as it did before.
The power steering pump is designed to pump oil into the steering mechanism and ensure fluid circulation in the system. During rotation, the pump shaft and blades create a centrifugal force, as a result of which the working fluid enters the discharge cavity under high pressure and then into the power steering system. The power steering pump is mounted on the engine and driven by a belt drive.
As a rule, replacing the power steering pump is carried out in conjunction with changing the oil, clamps and hoses. In this article we will look at how to perform this procedure with your own hands using the example of a VAZ-2110 car.

Replacing power steering fluid in a Chevrolet Niva (VAZ 2123)
Actually, having stopped by to specially adjust the headlights before the maintenance, the local master, who was starting his own business, decided to lure me to his place by opening the power steering reservoir cap and pleased me with a quick replacement, so the oil there was dark in color and smelled of burning. He asked for 1000 rubles for the work. Ha! Yes, I'm over a thousand... In short, we climbed onto the glorious Lacetti club www.lacetti-club.ru/vb_forum/index.php where I found a detailed description of the operation www.lacetti-club.ru/vb_fo...php?p=755031&postcount=72 But there was no photographs. But it will be easier to navigate using the pictures. Even in driving schools they study traffic rules from pictures. I decided to correct this misunderstanding. In general, I found some time and got to work. To replace, we will need the following tools: a medical syringe
Draining oil from power steering
Using a jack, we raise the front part of the car, having previously installed stops for the rear wheels. Then open the hood and pump out the oil from the power steering reservoir. The easiest way to do this is with a bulb or syringe. For convenience, use an extension hose for the syringe. After the oil has been completely pumped out of the tank, you need to turn the steering wheel several times until it stops, alternately left and right, so that a new portion of liquid appears in the tank. We pump it out again. Again we repeat a similar procedure with rotating the steering wheel and pumping out the oil.
Causes of failure
I know two reasons for the breakdown. This fitting is removable and is pressed in manually. Oil enters the power steering through this fitting. The most common reason is that the cars are already old, on average thirteen to fifteen years old. Accordingly, this fitting has an oil seal; with age it can leak. That is, this oil seal requires replacement.
But as it turns out, I have a different reason. This fitting has burst. I'm not the first owner, so I don't know what happened to the fitting before me. As it turns out, the fittings are not sold as consumables and are not supplied separately.
The oil seal most likely comes with the power steering kit. A power steering kit with oil seals is available. Therefore, before I find the spare part I need, I decided to repair the power steering “according to Kolkhokh”.
Replacing power steering hoses
Simultaneously with replacing the pump or power steering fluid, it is recommended to thoroughly check the condition of the hoses and pipes. If necessary, replace them with new ones. Hoses must be changed only after the oil has been completely pumped out.
To replace hoses or pipes, first unscrew the clamps. Installing new hoses causes some inconvenience, since the location of the hydraulic booster is not entirely convenient for performing such operations. New hoses and pipes should be securely secured with clamps. However, you should not be too zealous so as not to damage them.
Let's remove the power steering pump
As a rule, ZF version power steering pumps are installed in VAZ-2110 series cars. These devices are also equipped with hydraulic boosters of some models of Volkswagen, Audi A6 and so on. Pumps usually cannot be repaired and, if necessary, are replaced with new ones. However, in some cases, you can try to restore their functionality with your own hands, for example, replacing a worn bearing or cuff. It all depends on the nature of the malfunction.
Removal sequence for power steering pump:
Loosen the clamp and remove the return hose. When doing this, care must be taken not to spill the oil.
We very carefully remove the sensor from the fitting bolt, which is designed to measure fluid pressure in the power steering system.
Remove the fitting bolt and disconnect the discharge pipeline.
Remove the power steering drive belt.
After this, we proceed to dismantling the direct pump.
First, loosen one mounting bolt.
Then unscrew the second bolt and remove the complete power steering pump assembly.
We install the new pump in the reverse order.
Installing power steering - step by step instructions
This instruction is intended for VAZ 2110 cars, which do not have power steering at all. Such models were produced a long time ago, but they can still be found on the road today. In this case, the car can be upgraded with your own hands.
You can install the power steering yourself; for this you will need a power steering kit - today it can be purchased for about 20 thousand. From the tools, prepare a set of keys and screwdrivers; you should also take care of the amplifier fluid in advance.
- We dismantle the timing case and install the bracket on three bolts. There are already holes in the interior, so there is no need to drill new ones. Now we install the pin on which the roller will later be installed. There are no holes for it, so we make new ones. Let's put on a video.
Here you can see the fasteners that need to be removed. The photo below shows in detail what needs to be sawed off. After this, securely fix the pump on the bracket and cover it with a pillow. The assembled unit should be placed on the engine, or rather, in the place where the generator was mounted.
Pour fluid into the power steering
After replacing the power steering pump, you need to fill the system with new fluid:
First, pour oil into the tank until about.
Then we sit in the cabin and turn the steering wheel several times all the way in both directions so that the fluid fills the system.
After this, add oil to the barrel and turn the steering wheel again.
Add fluid, start the engine and turn it off after a few seconds.
Rotate the steering wheel several times until it stops in both directions.
Add oil to the tank again.
We turn the steering wheel at least 10 times all the way in each direction with the engine off to thoroughly bleed the system.
We start the engine and again turn the steering wheel in both directions 10 times.
We control the oil level in the tank and add fluid if necessary.
Niva Chevrolet Niva Chevrolet replacing the heater hose using the dentist's method
Intensive use of the Chevrolet Niva makes the color of the power steering oil darker over time, often with a burning smell. This is a reason to think about replacing it.
Overheating of the oil often occurs when the steering wheel is held in the extreme position for a long time, until it boils; the pressure in this case is maximum.
You should also not leave your car parked for a long time with the steering wheel turned all the way. There are two ways to replace the fluid in the Chevrolet Niva power steering: To partially replace the power steering oil, you will need a syringe with a tube and the oil itself, enough so that at the end of the work it will no longer be dark.
Transmission Chevrolet Niva (Chevrolet Niva). Structure and operation of mechanisms. (copy of video)
Using a syringe with a tube, completely pump out the fluid from the power steering reservoir. Fill the reservoir with new fluid to the MAX level.
Chevrolet Niva 2005, 80 l. With. — scheduled maintenance
We start the engine and turn the steering wheel left and right to the extreme position. Drive onto an overpass, or jack up the car so as to hang the front wheels of the Chevrolet Niva, in order to be able to easily rotate them with the engine not running.
Use a syringe with a tube to remove as much old oil as possible from the tank. Now you need to determine through which hose the oil enters the Chevrolet Niva power steering expansion tank - this is the return, and through which it leaves and goes to the power steering pump. Disconnect the hose through which the oil enters the return tank.
