Cars of the Lada Grant family are equipped with power steering as standard. Electromechanical power steering (hereinafter referred to as EPS) is installed individually by the owners.
Electromechanical power steering
ESD is a relatively new development of modular control, which, like power steering, has advantages and disadvantages.
Operating principle of the EUR
Every time you turn the steering wheel, the torsion shaft twists. Information about this process is transmitted from the torque sensor to the control unit online.
Based on the information received, the electronic control unit (hereinafter referred to as the ECU) accumulates information and reads readings from other sensors. The ECU transmits a signal to the electric motor, which increases the torque of the steering rack shaft by activating the electric motor.
Information is processed so quickly that tenths of seconds pass from the moment of transmission to the moment of reading.
Is it worth installing electric power steering?
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 electric motor support.
Installing such a mechanism has certain difficulties and is also associated with costs. But they will all pay off in a comfortable ride and increased safety for you and your passengers.
Thus, the answer to the question “Is it worth installing?” - this is a definite “Yes”. Even if you don't 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 power steering (the author of the video is AVTOTEMA TV).
Possible malfunctions of the EUR
It happens that after installation the EUR does not work at all or intermittently.
This can be caused by various reasons, among which two most often stand out:
- Speed sensor failure. The electric power steering operates in connection with the speed sensor. At high speeds, the extra force from the mechanism is reduced to give you more control. If data from the sensor stops flowing, the EUR will automatically turn off. The problem is solved by replacing the sensor.
- Incorrectly installed engine crankcase. If there is a violation in the installation of the engine crankcase (casing), vibrations from the engine will be transmitted to the amplifier. It will begin to buzz, and in some cases even turn off.
Possible malfunctions of the EUR on the Lada Grante Liftback (Sedan)
| Malfunction | Diagnosis | Elimination method |
| The diode on the side pillar glows due to a faulty speed sensor. | Checking the serviceability of the speed sensor by dismantling it and ringing it with a multimeter. | Replacement of the sensor with a new one, since the design is not subject to repair (partial, complete). |
| Low voltage in electrical wiring. | Checking the integrity of the insulating layer and contact terminals. | Replacement of damaged cable sections, insulation of connection points. |
| The electric amplifier rotates slowly. | Checking the voltage supply to the input contacts from the relay regulator. | Replacing the relay regulator. |
| During rotation, a characteristic creaking, metallic grinding sound is heard. | Dismantling the EUR, disassembling it into its component elements, checking the condition of the rolling bearings. | Replacement of two rolling bearings with new ones. |
Steering mechanism malfunctions and their elimination
The steering mechanism of the Lada Granta is quite reliable and rarely causes problems for the owner. However, this does not mean that problems do not occur at all. There are problems. And you need to know how to eliminate them.
| Cause of problems |
Elimination
Like the braking system, engine operation and other important components and assemblies, the steering system must be periodically inspected for malfunctions. If there are no signs, protective boots and other smaller structural parts must be inspected. The steering rack of the Lada Granta is a key control mechanism. It is thanks to this that the car is controlled by turning the wheel.
Not only the comfort of control, but also the safety of the driver and his passengers depends on the serviceability of the steering mechanism. Unit problems must be diagnosed and corrected in a timely manner.
Basic steering rack faults
The main sign of a breakdown is a knocking sound when turning. At first it is almost invisible and appears when hitting potholes. If you ignore the first symptoms, the noise will not go away and will constantly get worse. Then the knock will be transmitted to the steering wheel. If you ignore this symptom, the rack will simply jam, and this risks getting into an accident due to loss of control. The rack knocks due to wear of the hinges, teeth or rubber-metal bushings (damper).
The following symptoms can also be attributed to steering rack malfunctions.
- The steering wheel turns hard (accompanied by a slight whistle).
- The tight rotation stops as the speed increases.
- With straight steering, there is no gain.
- When turning, the steering wheel does not turn the front wheels properly (the car begins to roll left/right while driving).
- Vibration, beating, grinding; the steering wheel begins to rattle.
- The steering wheel does not return to its original position.
- The steering wheel rotates spontaneously.
There are many reasons for steering rack malfunctions. But these are the most common. If at least one of them occurs, the Lada Granta should go for repairs as soon as possible.
DIY steering rack replacement
For novice motorists, this may seem like an overly complicated procedure. But in reality everything is simpler. The algorithm of actions is as follows.
- Disconnect the battery, loosen the bolts of the front wheels, hang the front on jacks and remove the wheels.
- Inside the car, you need to unscrew the bolt that connects the steering gear terminal to the intermediate shaft. In this case, the steering wheel must be in a straight position (the wheels are strictly straight).
- Disconnect the rods from the swing arms.
- Unscrew the steering mechanism mounting nuts through the gaps in the wheel arches.
- Dismantle the clamp and remove the steering mechanism assembly.
- Next, all anthers and their fastenings are removed.

Purpose, advantages and disadvantages of an electric amplifier
The EUR appeared quite recently, much later than the well-known and proven steering wheel. Its task is the same - to facilitate the rotation of the steering wheel, but the operating principle is different.
If in the first case the main function was performed by a special fluid for the power steering, then here the electric drive takes on the role of an “assistant”.
Since its inception, the system has been constantly improved. At the same time, from year to year, the electric power steering takes over the “reins of power” and gradually replaces the power steering.
What are the benefits of electric power steering? There are a few:
- Setting steering parameters is much easier;
- the steering wheel responds better to driver movements;
- the level of reliability has increased. This is due to the fact that the performance of the system no longer depends on the volume and quality of the special fluid;
- reduction in fuel consumption.
It would seem that there may be a pattern. It's simple. With the advent of the electric drive, less energy was consumed, and accordingly, the “gluttony” of the car decreased by an average of 0.5 liters (per “hundred”).
But, despite its qualities, the EUR also has a number of disadvantages:
- the generator has limited power, which affects the operation of the entire system. Consequently, installation of an electric motor is only possible on passenger cars. An amplifier of this type is not suitable for trucks or SUVs - it will be ineffective;
- low information content of the steering wheel (this can be explained by insufficient reverse force). To be honest, the “big brother” - power steering - has a similar drawback.
With the advent of electric power steering, developers have many opportunities to develop more modern systems, for example, automatic parking, stability control systems, and so on.

Video “Installing electric power steering”
This video talks about the pros and cons of such a system, and also demonstrates the installation process in detail (the author of the video is sokur64).
Welcome to ChipTuner Forum.
Theme Options
I drove a new (from the showroom) Grant, the EUR is completely unclear
At a standstill and crawling around the city (up to about 30 km/x), the EUR works clearly, there is feedback on the steering wheel. The steering wheel rolls back, the car returns to straight-line motion.
After 40 km/h. The steering wheel becomes stiff, there is no self-return, you have to force it back all the time. The steering is tight, there is zero feedback from the road, you steer only by eye. After 350 miles, my arms fell off. It looks like the rack is being tightened to death.
Anyone who has extensive experience with TAZ EURs, please tell me what it is. Another VAZ masterpiece. A programming glitch on the EUR (no errors are displayed) Or everything will “get used to” and forget about it for now.
I have a question. Who has a grant in the “standard” configuration, which one to drive without an electric steering system? I understand that you can survive the lack of many options, but without an EUR it seems really difficult to me, especially when you have to maneuver in busy courtyards, streets and parking lots.

Preparatory stage before installing the EUR on the Lada Granta
Note to the driver! There are no differences in installing the EUR on the Lada Granta Sedan and the Lada Granta Liftback. Factory mounts are identical.
Required tools:
- EUR (11186-3450008-02): synchronous power unit, control controller, brackets, shaft, gearbox;
- intermediate bracket (11186-3403172-00);
- non-separable intermediate steering shaft (72780);
- blocks with wires for connecting to the central power circuit (2110-3724155);
- LED indicating the good condition of the amplifier;
- plastic clamps;
- fasteners;
- set of automotive tools;
- insulation;
- clamps.
Installation instructions
This manual is intended for those who have minimal skills in working with tools and vehicle systems. It is made as accessible as possible to everyone. But if you doubt your skills and knowledge, it is better to contact a car service.
Required tools and materials
First of all, you will need the EUR itself. Please note its serial number. The last two digits indicate the type and place of production.
So, 00 is a geared amplifier, produced in Makhachkala and has received complaints from drivers. With the numbers 04 - Korean, installed on Grants and Kalinas, a good amplifier, can be found in stores, but there are few of them on sale. Well, 02 - Kaluga, gearless type, also has good reviews.
To connect, you will need common tools such as screwdrivers, wrenches, and an angle grinder.
Installation process
First, you will need to completely remove elements such as the airbag, steering wheel, switches, ignition switch, and finally the steering column along with the bracket and cardan.
Then do everything as follows:
- Taking the old bracket-plate, 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 the plate on the EUR, if the holes do not match (most likely this will happen), drill them.
- Now you need to attach the gimbal to the amplifier.
- You need to put washers under the bracket at the point of attachment to the amplifier. They can be of different thicknesses and have a direct impact on future steering adjustments.
- Now you can attach the EUR. Insert the cardan onto the rack.
After all this you need to connect the wiring. Below is the connection diagram.
