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.

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).

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.

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.

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.

The shaft bearings are worn out.The shaft bearings need to be replaced.
The electric power steering is faulty.Replacement of the EUR together with the shaft.

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.

  1. The steering wheel turns hard (accompanied by a slight whistle).
  2. The tight rotation stops as the speed increases.
  3. With straight steering, there is no gain.
  4. When turning, the steering wheel does not turn the front wheels properly (the car begins to roll left/right while driving).
  5. Vibration, beating, grinding; the steering wheel begins to rattle.
  6. The steering wheel does not return to its original position.
  7. 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.

  1. Disconnect the battery, loosen the bolts of the front wheels, hang the front on jacks and remove the wheels.
  2. 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).
  3. Disconnect the rods from the swing arms.
  4. Unscrew the steering mechanism mounting nuts through the gaps in the wheel arches.
  5. Dismantle the clamp and remove the steering mechanism assembly.
  6. Next, all anthers and their fastenings are removed.

Now you can install a new steering rack (if you did not use a repair kit). The assembly is assembled in the reverse order. The position of the rack should be adjusted so that the marks on the crankcase coincide with the marks on the protective boot. The last operation when replacing a unit is to adjust the front wheel alignment.

If the rack has been repaired, all parts are generously lubricated with special lubricant (lack of lubrication shortens the service life of the steering rack).

In most cases, the cause of rack failure is motorists ignoring to inspect the car for faults. A thorough diagnosis of all components and assemblies is carried out at least once a year.

What you can do yourself and when is it better to turn to specialists

If individual parts are changed, you can carry out the work yourself. But a complete renovation will require compliance with additional conditions. For example, a straightening stand is always required. Not every home master will be able to provide it.

  • The first stage is to disconnect the pipelines leading to the expansion tank and steering system.
  • At the same stage, draining the liquid is allowed.
  • After this, you need to remove the drive belt from the pump. If this part fails, it is completely replaced with a new one.
  • The pulley is fixed with three blocks; they must also be unscrewed. He himself approaches the pumping unit. But sometimes a larger number of fasteners are used, it all depends on the specific system.

But sometimes performing these actions is not enough. The filter system deserves special attention.

Violations at the cleaning stage are not excluded, even if, in general, the main function is performed correctly. In a garage environment, such violations cannot be detected.

In this case, it makes sense to turn to professionals.

Getting rid of excess air

We can say that the owner is lucky if the cause of the problem lies precisely in the presence of excess air. But here too there is a lot of ambiguous things. Sometimes, to solve the problem, it is enough to turn the steering wheel in both directions until it stops.

Practice has shown that this is enough to push excess air out. If after this the movements are still tight, the tank is probably filled with air; this happens often. This means that the work uses a liquid that contains air bubbles. To fix the problem in this case, it will be enough to completely refresh the fluid.

  • Innokenty: comrades recommended installing an EUR. I bought it at the Motel Varshavsky parts store. Good quality, reasonable prices, bonuses when purchasing.
  • Vladlen: I drove the power steering for two years and decided to switch to the electric power steering. They advised to buy from Expert-Auto. Six months have passed since installation, no complaints, my recommendations.
  • Vyacheslav: I’m leaving my positive review about the auto parts store “Spare Parts on Wheels”. Professional advice, reasonable prices, friendly staff.

Common reasons

There are reasons that do not depend on the type and condition of the steering elements, these include low tire pressure and incorrect wheel alignment, violation of body geometry, etc.

In the first case, due to the large contact patch between the tire and the road, not only tire wear increases, but also the load on the steering wheel increases, which begins to turn tightly. In the second case, incorrect wheel angles also lead to this malfunction. We'll talk about the influence of body geometry later.

You should also pay attention to the steering knuckle bearing, shown below in the Nissan Primera example. Due to the wear of the boot, it rusts, as a result you have to make more effort when turning.

And yet, it is important to understand that if other tires were installed on the car and they are larger and wider than the previous ones, then the steering wheel will be difficult to turn and this is natural, there is no need to panic.

It is also worth paying attention to the crosspieces (universal joints) of the steering column. There may be one or two of them (lower and upper), it all depends on the design. The crosspieces may bite or after installing new ones, the steering wheel will be difficult to rotate for some time.

Be sure to pay attention to the cardan boot, for example, on the Toyota Caldina 2.0 MT 4WD FULL it looks like this.

If it is torn, then replace it, since over time, water and dirt that gets there will lead to bad consequences. The first sign that the problem is in the crosspieces is a tight rotation of the steering wheel with cyclic jerks.

Also, different behavior of the steering wheel is possible as a result of linear expansion of the parts. As a rule, if the tolerances and fits in the parts are selected correctly, and this also applies to the crosspieces, then after they are heated or cooled, no jamming occurs, and the steering wheel turns easily and smoothly.

If these parameters are not maintained correctly, and this no longer applies to original spare parts, then the steering wheel will be difficult to turn, with jamming both when the engine is cold and when it is warm.

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.

  • 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.

After this, access to the fixing elements of the pump itself opens. Power steering repairs begin after this stage has been completed. To do this, change the internal fluid and update the hoses along with the drive belt.

But sometimes performing these actions is not enough. The filter system deserves special attention.

Violations at the cleaning stage are not excluded, even if, in general, the main function is performed correctly. In a garage environment, such violations cannot be detected.
