Grant's steering wheel and VAZ 2114 are an important element of car control. most common in this system? What are the ways to upgrade the node? Before answering these questions, you need to clearly understand what steering is.
To date, the two latest developments of a domestic enterprise and the VAZ 2114 are the undisputed leaders in the Russian market. Original, stylish, powerful, these machines deserve special attention and positive evaluation. Assembled using new technology, Grant and VAZ 2114 aroused wide interest among motorists. But, of course, any, even the best, development has its drawbacks, which the owner should know in order to avoid any problems during operation. In particular, the steering can bring a lot of surprises.
Steering functions
Steering is the system that keeps the vehicle moving. It consists of a steering wheel, rack, mechanism and drive. The principle of operation of the steering wheel is based on the fact that the wheel receives the impulse of the effort made by the driver and transmits it to the mechanism, which reacts in accordance with the direction given by the driver. That is, when the driver turns the steering wheel, he transfers the turning force to the mechanisms that are connected to the front wheels, this is how the movement occurs.
The device of the steering mechanism Lada Granta
The steering wheel of a passenger car differs from the steering wheel of a truck primarily in diameter. In the first case, it is 390-420 mm, in the second - 445-545 mm. Sports cars have a smaller steering wheel than the standard steering wheel found on a regular passenger car. In addition to the diameter, there is a difference in the control mechanism.
Today, there are several types of steering column, ranging from conventional and inexpensive to built in a style that allows it to fold in a high frontal impact. In addition, the steering columns have both mechanical and electrical adjustment, which is very convenient when you need to adjust the height of the steering wheel or its direction.
In the samples of recent years, owned, there is a steering column, which is easy to rearrange from the driver's seat to the right passenger's seat. The steering mechanism is a device that transmits vibrations from the force of impact on the steering column to the drive.
There are several types of steering mechanism, the most common of which is rack and pinion.
It is also found in Russian models Lada Kalina, Grant, VAZ 2114 and other AvtoVAZ projects. But the legendary BMW, Toyota, Mazda and others are equipped with a more complex steering mechanism, with the principle of operation on all four wheels. This solution guarantees greater stability and excellent handling.
The drive transmits the force from the steering mechanism to the wheels. To date, several drive designs are known, depending on which one. The most popular and well-known is the mechanical drive, which consists of hinges and rods. This type of design is found both in Russian models, such as Grants, and in European projects.
Power steering types
Power steering hydraulic type design
In order to make the steering more efficient and comfortable, reinforcement is applied. Mechanisms are divided into three types:
- electric booster;
- hydraulic booster;
- pneumatic amplifier.
The electric power steering is powered by electricity and has a rather complex structure. The EUR noticeably improves the dynamics, maneuverability, controllability of the car, in some cases even allows. Electric power steering today is available not only in foreign cars, as it was ten years ago, but even in domestic models, such as. You can buy it at any auto shop in the country.
The principle of operation of the power steering is to pump hydraulic fluid. The hydraulic booster has a good ability to soften the blows that fall on the steering wheel during high-speed traffic on a bumpy road. The mechanism also improves maneuverability. The only way it can be inferior to an electric amplifier is that it is not economical, but more efficient and reliable. The pneumatic booster is a modern option, still rarely found in cars, and even more so not found in domestic projects, although you can buy it now in large car dealerships.
Steering Features Grants
The steering wheel from Grants is a standard, rack-and-pinion type, the drive consists of two steering rods, combined into a single structure due to ball joints. Theoretically, it is not bad, but practice shows otherwise. The tie rod holes are just incredibly huge, which is good for air exchange but bad for pollution. Surprisingly, such practical masters of AvtoVAZ somehow did not think about this urgent issue before. To correct this defect, many car owners put simple Lada steering rod plugs.
Most often, the steering wheel from Grants suffers from loose fasteners. What can be done in this case? All you have to do is tighten the nuts. You can also note the occurrence of knocks in the steering wheel. To fix the problem, it is worth tightening the nuts if they are loose, or replacing parts if, upon inspection, you find that they are worn out. With a tight rotation of the steering wheel of the Lada Grant, you will have to change the bearing. In some cases, it is necessary to repair the suspension strut and lubricate the parts.

How to reduce the fuel consumption of a car Lada Granta
Installing the EUR on the Grant Standard is a common reason for the owners of these cars to contact a car service. However, with due skill, you can quite do everything yourself. How to install such a system, if you have a Lada Grant and whether it is worth doing it at all, read the article.
Driving a car without electric power steering is, of course, possible. But if you have previously driven a car equipped with such a system, you may experience serious discomfort. You will be deprived of the usual support of the electric motor.
Installing such a mechanism has certain difficulties, and it is also associated with costs. But they all pay off with a comfortable ride and increased safety for you and your passengers.
Thus, the answer to the question "Is it worth it to install?" is an unequivocal "Yes". Even if you do not want to do it yourself, contact a car service.
In the video below you will find a comparison of the advantages of power steering and EUR (the author of the video is AUTOTEMA TV).
Possible malfunctions of the EUR
It happens that after installing the EUR does not work at all or intermittently.
This can be due to various reasons, among which two most often stand out:
- Speed sensor failure. The electric power steering works in connection with the speed sensor. At high speed, the additional force from the mechanism is reduced to give you more control. If the data from the sensor stops coming, the EUR will automatically turn off. The problem is solved by replacing the sensor.
- Incorrectly installed crankcase. In case of violations in the installation of the crankcase (casing) of the engine, vibrations from the motor will be transmitted to the amplifier. He will begin to buzz, in some cases even turn off.
Installation instructions
This manual is intended for those who have minimal skills in working with tools and vehicle systems. It has been made as accessible as possible for everyone. But if you doubt your skills and knowledge, it is better to contact a car service.
Necessary tools and materials
First of all, you will need the EUR itself. Pay attention to its serial number. The last two digits indicate the type and place of production.
So, 00 is a geared amplifier, produced in Makhachkala and have complaints from drivers. With the numbers 04 - Korean, put on Grants and Kalina, a good amplifier can be found in stores, but it is not enough at the collapse. Well, 02 - Kaluga, gearless type, also good reviews.
To connect, you will need such common tools as screwdrivers, wrenches, grinder.
Installation process
In the beginning, you will need to completely remove such elements as the pillow, steering wheel, switches, ignition lock, and also at the end the steering column along with the bracket and cardan.
- Taking the old plate bracket, knock out the bolts from it. Then cut off about 30 mm from the top (where 2 bolts are welded and there are 3 holes).
- Try on the plate to the EUR, if the holes do not match (most likely it will), drill them.
- Now you need to attach the gimbal to the amplifier.
- Washers should be placed under the bracket at the point of attachment to the amplifier. They can be of different thicknesses and have a direct impact on the steering wheel adjustment in the future.
- Now you can fix the EUR. Insert the cardan onto the rail.
After all this, you need to connect the wiring. Below is the connection diagram.
Steering wheel adjustment
As mentioned above, washers matter how much the steering column will deviate up and down. They are installed between the bracket and the amplifier. The amount of deflection of the steering column depends on their thickness.

Removal and installation of the electromechanical power steering Lada Granta
Electric power steering reduces effort on the steering wheel, making it easier to drive. The basis of the electric booster is a brushless electric motor with a gearbox located under the steering cover. A worm is installed on the engine shaft, which engages with a plastic gear mounted on the steering shaft. The electronic control unit coordinates the operation of the electric booster by changing the voltage supplied to the electric motor according to information received from the sensors of the vehicle speed, crankshaft speed and the amount of torque on the steering shaft. The electric motor through the gearbox turns the steering column shaft with a certain moment.
The control unit provides sufficient information content of the steering wheel in all modes of vehicle movement. When the car is at a standstill, the moment created by the electric booster on the shaft is maximum, with an increase in the speed of the car, the “help” of the booster decreases and the steering wheel becomes “heavier”. In the event of a failure of the electric booster, the car retains full controllability, while the steering wheel becomes somewhat “heavier” than on a car without an electric booster. since there is an additional load in the form of a freely rotating rotor of the electric motor
In the instrument cluster there is a signaling device for a malfunction of the electric power steering. It lights up when the ignition is turned on and goes out after the engine is started. If the electric booster fails, the signaling device lights up constantly. The electric booster does not work when the engine is not running.
The electric booster can be turned off:
- with a decrease in the voltage of the on-board network;
- in the absence of a signal from the speed sensor and the engine speed is above 1500 min 1
Such shutdowns are incorporated in the operation algorithm of the electric amplifier and are not signs of a malfunction.
Withdrawal
You will need: a screwdriver with a Phillips blade, keys "8", "13" (two), socket wrench "13".
1. Disconnect a wire from the minus plug of the storage battery.
2. Remove the steering wheel.
3. Pull towards you and remove the fuse block cover.
5. Remove the steering column switches.
Most of today's cars are equipped with a cabin air filter. In the basic configuration, such a filter is available for cars of the Lada Granta model. Its task is to filter the air entering the cabin from the outside. If one filter runs too long, the stove does not work well, the air in the cabin is not cleaned, bacteria and dust particles appear in it.
According to manufacturers' recommendations replacement cabin filter Lada Granta should be carried out every 5-7 thousand kilometers. However, one of the signals that a new filter needs to be installed prematurely is dust or an unpleasant odor coming from the air ducts.

Dear customers, in order to avoid shipping errors,electric power steering EUR VAZ 1117, in the "Comment" line, indicate the model of your car, the year of manufacture.
An electromechanical power steering is a device that is currently installed on most cars, both foreign and domestic. Its presence in the car is explained by a very important factor, this is an increase in the safety of the driver and passengers, because. driving a car that is equipped with a device such as power steering is much easier and easier.
EUR - Electromechanical power steering is a fundamentally new design of the through type, without the use of a mechanical gearbox and is designed to reduce the control force applied by the driver to the steering wheel.
Electric power steering for cars Lada Granta, Kalina of all modifications. Part number according to the catalog of spare parts of JSC "AVTOVAZ": 1117-3450008-04. Interchangeable with EUR 11186-3450008-02. Manufactured by Mando South Korea. Supplied to the AVTOVAZ assembly plant.
Regular installation without additional adapter plates.
The principle of operation of the EUR (electric power steering) is based on the fact that when the steering wheel is rotated, the torsion shaft of the amplifier is twisted. The amount of this twisting is fixed by the moment sensor that is installed in it. Based on these values, as well as data from the speed and crankshaft speed sensor, the electronic control unit calculates the necessary force to compensate for the resistance applied to the steering wheel by the driver, and then sends a command to the power steering motor.
The main requirements that a gearless electric amplifier provides:
Reduces the energy costs of the driver;
Provides optimal load and speed characteristics of the steering in terms of ergonomic conditions;
Provides rectilinear movement of the car in case of damage to tires or suspension;
Retains the ability to drive the car when the amplifier fails;
Maintains the stabilization of the wheels, that is, keeps them in a neutral position when exposed to various disturbing factors.
Power steering is especially relevant in extreme conditions, as it provides comfortable and reliable driving.
The main advantages of the EUR over the hydraulic booster:
1. Manufacturability of the installation. Mounted on the car with one node without intrusion into the engine compartment;
2. Installation time - no more than 1.5 hours;
3. Reliability. There are no components inherent in hydraulic boosters (hoses, pulleys, fluids);
4. Provides passive safety upon impact, has a built-in self-diagnosis system;
5. Environmentally friendly and energy saving. Consumes power only when maneuvering, which significantly reduces energy costs and leads to fuel economy;
6. Informative. Provides an increase in effort on the steering wheel with an increase in vehicle speed.
Main technical characteristics of EUR VAZ 1117-345008-04:
Rated supply voltage 13.5 V;
Current consumption no more than 55 A;
Compensating torque 28±1 Nm at 360°/sec steering wheel speed;
The main advantages over the gear version of the electric amplifier:
1. Reliability. Direct transmission of the moment applied to the steering wheel to the steering rack, in contrast to the gear version, where there is a gear;
2. Performance. Ensuring a high degree of response from the steered wheels to a change in the position of the steering wheel;
3. Very low noise level.
The amplifier belongs to nodes with increased safety requirements. In the event of a malfunction of the amplifier, it automatically turns off, while driving becomes the same as on a car not equipped with an amplifier.
If you are in doubt whether to buy an electric booster or not, then just take a ride in a car equipped with an EUR. After such a test drive, your doubts will most likely disappear and it will be easier to make a decision to purchase such a device.
