Checking the steering condition of Lada Granta

Cars of the Kalina-2 family are equipped with a steering rack similar in design to the Granta rack. This part transmits force from the steering wheel to the front suspension links. If you feel a knocking sound from the rack while driving, it needs to be adjusted (tightened) correctly. The effect described here can be observed after 10-15 thousand kilometers, and more often it makes itself felt on uneven roads. Next we consider how this problem is solved in practice. And the solution comes down to turning one nut.

A little theory: front suspension design

Before attempting to fix any problem, there is a tendency to look at the blueprints or repair manual. It is known that the VAZ-2192 parts catalog contains the following object:


This is what the steering rack looks like in the drawing

Whether the knock will remain in the steering rack of Kalina-2 depends on the following: how accurately element “14” is adjusted. The adjusting nut, marked “14”, looks almost invisible here. But first impressions are deceiving. In the catalog, by the way, the element is called “Stop Nut”.

It is important to know that the thrust nut has external threads. And it spins clockwise. And the words “tighten the rack” mean screwing in the specified nut, and nothing more.

Now let's move on to practice and see what the node in question looks like in reality:


If you remove the rail, it looks like this

The nut has a non-standard notch, and it can only be rotated with a special tool. By the way, the recess will be closed with a cap. In the catalog it is designated by the number “15”, and now, let’s look at the appearance of the special key:


Rack adjustment key

The thrust nut is turned at small angles. We are talking about values ​​of 10-15 degrees. What happens if you overdo it with tightening the rack? The knocking noise will disappear, but the steering wheel will turn with difficulty. Therefore, if necessary, the nut can be pulled back.

Diagnostics, repair and reassembly

Before determining why there is a knock in the steering, you should completely disassemble the rack and carry out diagnostics for wear, destruction of components and connections. Disassembly is carried out in this order. Secure the steering rack in a vice, having previously installed spacers made of soft metal or other material. Unscrew the nut securing the mechanism crankcase pipe. The crankcase tube is removed. Remove the clamps securing the pipe bushings and remove them.

Unscrew the adjusting nut. Here you need to use a special 24mm wrench, which has external edges for unscrewing. Sequentially remove the rack stop spring, the sealing ring and the rack stop. Remove the crankcase cover. After removing the bearing cage and sealing ring, remove the rack. The second element of the steering mechanism pair - the gear shaft - is dismantled.

Now you can diagnose the condition of the bearings and sealing rings. After thorough cleaning, the wear of the gear sectors and the condition of the surface of the rack and shaft are assessed. After all, this is where the reason lies that causes the knocking that appears. If necessary, select the necessary parts and replace them.

Before reassembly, all critical connections are lubricated with a special compound. Very often, it is the insufficient amount of lubricant that leads to rapid wear of loaded parts, which violates the previously established clearance. Therefore, even a recently installed rack knocks again.

Assembling the steering mechanism is carried out in the reverse order. For correct and easy installation of dismantled bearings, you should select the required diameter of pipe cutting, which will help to correctly install the bearings in place. The assembled steering mechanism must be adjusted, since the size of the gap can also determine whether a knock will appear after reinstallation.

Lyrical digression

In Lada Kalina, the steering rack never makes a knock when we are talking about a new car. This is also true for the break-in period. Let's say in your case this is not done. Then, do not try to repair anything, but go straight to the dealer. According to reviews, the defect in question is covered under warranty, and most car dealers do this: the steering rack assembly is replaced with a new one.


This is what the replacement unit looks like, the rack assembly

There is a logic here. At the factory, adjustments are made correctly (this is true in 99.9% of cases). If a defect appears, the dealer replaces the assembly without expecting that adjustment will solve the problem. The owner does not need to hope for this either. The choice is yours.

How to avoid

To avoid the appearance of new knocks after repair, you must follow a few simple rules:

  • Do not reach high speeds on uneven and gravel-covered roads, as well as when driving over potholes and potholes. And if you still can’t avoid this, be sure to ensure that the steering wheel is not in the extreme position at the moment the front wheels come into contact with the obstacle.
  • Do not make sudden acceleration or braking when the steering wheel is in the extreme position.
  • Do not drive onto curbs or high curbs.

Thanks to following these simple rules, knocks will not bother you for a long time, and the steering rack will last even longer.

Making adjustments yourself

You can access the adjusting nut from the engine compartment, but to do this you will need to remove the battery, as well as the battery mounting pad. It is better to drive the car into a pit and then remove the crankcase protection (engine mudguard). If you look from under the bottom, the required element is immediately visible:


You need to turn this nut

And when you open the hood, you can feel the nut, but not see it. Its location is marked in the figure:


To make adjustments, place the key here

Before adjustment, remove the rubber cap from the recess. Its appearance is shown in the photo:


Remove the cap and install the key

If it is not entirely clear what exactly needs to be done, it is better to contact the service. The key is installed in the recess and then rotated 10-15 degrees.

When looking at the rack from above, turning the key clockwise corresponds to unscrewing it. The handle of the key comes from the center of the car - which means tightening is being done. By the way, the latter is true provided that the handle faces forward.

Preparatory actions, dismantling unnecessary parts

To remove the crankcase protection, you need to unscrew 4 screws located in one row near the bumper. Also, unscrew two screws having a standard size of M6x16. In some configurations, the protection consists of two parts, but in this case they are attached only with self-tapping screws. These words are illustrated by the following photo:

First, unscrew the “10” screws, and then the two “18” screws. In the second case, there will be more screws (eight).

Now let's look at how to remove the battery. First of all, disconnect its terminals. Then, you need to move the additional fuse box to the side. In general, actions are performed according to the photo:

It turns out that the steering rack can be repaired (video example)

The knocking of the steering rack on the Grant was inherited by this car from the younger model - Kalina. In fact, the design of the rack is no different and the catalog number remains the same. As for adjusting the steering rack, you can do it yourself, having the necessary tool at hand:

  • special wrench for tightening the rack
  • 10mm socket and ratchet (for unscrewing battery terminals)
  • 13 mm socket - for removing the battery pad
  • Phillips screwdriver

How to tighten the steering rack on a Lada Granta

So, there are two ways you can go:

  1. The easiest and fastest way is to tighten the rack using a special key, inserting it into the hole where the steering rod passes on the left side of the Granta body.
  2. The second method is longer - it is suitable if the hand does not fit into the hole in the body from the wheel side. In this case, you will have to remove the battery and its platform to get to the adjusting nut.

So, with the first method everything is clear; as for the second, let’s consider it in more detail. First of all, unscrew and remove the terminals from the car battery.

Then we remove the battery and proceed to dismantling its platform.

Now that the platform has been removed, you need to get to the adjusting nut from the inside of the steering rack housing.

The rack is tightened clockwise, take into account the fact that it is in an inverted state, so the movement will be counterclockwise.

Please note that to adjust the rack on a Grant, you need to buy a special key, which is designed for the VAZ 2110 rack. Its price is no more than 150 rubles, and sometimes they are sold combined: on one side for the rack, on the other for the timing rollers.

Lada Granta was originally created as an inexpensive car. Actually, that’s why it became one of the most popular cars on the roads. The manufacturer tried to introduce both proven and new elements into the design. But they have their drawbacks. The Lada Granta steering rack can present various surprises during operation. It is useful for the owner of a domestic car to understand the structure of many components.

Removing the steering gear

If a knock does occur, the car owner will have to dismantle the mechanism. It is more convenient and faster to carry out this work when the vehicle is on a lift. To carry out the work you will need the necessary tools, which in this case include:

  • socket wrench or socket wrench 13;
  • flat screwdriver;
  • durable knife;
  • special 24mm wrench for the steering rack;
  • hexagon 6 with wrench.

Before starting work, the battery is disconnected, thereby taking the necessary safety measures. At the initial stage, you need to first loosen the bolts securing the front wheels. The wheels themselves should be left in the “straight” position before lifting the car onto the lift. Next, the steering wheel driveshaft is disconnected from the rack and pinion drive shaft.

This work is carried out from the salon. Therefore, the car is not raised high. The swing rods can now be released by unscrewing them from the swing arms. And as soon as this work is completed, you can begin to dismantle the steering mechanism. Using a 13mm wrench, unscrew the nuts securing it and remove the mounting clamps.

The steering mechanism is removed along with the disconnected steering rods. The next stage of repair work is disassembling the removed device. Here you should free the steering rack from all protective covers that are put on the mechanism. For this purpose, cut off all the fixing clamps, which will subsequently need to be replaced with new ones.

Steering of Lada Granta

It is designed to control the car while driving. Structurally, it consists of the following main elements:

The work of the mechanical part is that the driver acts on the steering wheel, the impulse through the steering mechanism and rack transmits force to the front wheels through the levers, and the car turns in the desired direction. A characteristic feature of a passenger car steering wheel is its smaller diameter (compared to a truck). The design of the mechanism also differs. The steering of the Lada Granta is complemented by an electric booster. The steering wheel can be adjusted in height. Unfortunately, there are no settings for departure.

The steering mechanism of the Lada Granta is rack-and-pinion type, the simplest and most inexpensive option.

The drive is mechanical, structurally consisting of levers, rods and hinges. For more efficient and convenient control, the Lada Granta is equipped with an electric amplifier. This is a complex mechanism that provides force through the use of electricity. An electric power steering, or simply EPS, is used to improve dynamic characteristics and controllability. And, according to some data, it allows you to save fuel by increasing the vehicle’s maneuverability.

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.

  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.

Steering rack adjustment

The unit knocks for various reasons. In fact, this is a real disease of the control mechanism, inherited from the Lada Kalina, since the components are identical on these cars. You can adjust the rack yourself.

To do this you will need a minimum of tools:

  • steering rack calibration key;
  • socket heads for 10 and 13;
  • shaped screwdriver.

To tighten the slats, you can use two methods. The first involves using a special key that can be inserted into the gap of the arch on the left side. The second method is more labor-intensive and is suitable if it is not possible to stick your hand into the gap. To do this, you will need to dismantle the battery and its platform; this is the only way to get to the nut for tightening the gearbox. The first method is simple, so it’s better to consider the second option.

Steering wheel tuning on Lada Granta

There are few options for upgrading the steering wheel on the Lada Granta. The most popular of them is installing a sports version. Such a steering wheel will not only make the interior more attractive, but will also increase the comfort of control, especially if it is selected correctly. You can install a multi-steering wheel, but only if the configuration is maximum, in other cases there will be nothing to control with its help.

The sports version must be injury-proof, that is, in the event of an accident it must be deformed without causing damage to the driver. Among the shortcomings, it can be noted that although there is an airbag in the standard steering wheel, the sports one does not have it. You can also modify the steering wheel by installing braid. More advanced ones install a heating thread under it.

To install the sports steering wheel, you will need to carry out the following operations.

  1. Align the front wheels straight (you can drive a little forward and back so that the trajectory is straight).
  2. Disconnect the battery terminals by de-energizing the vehicle's on-board network.
  3. The airbag control module must be disabled (if the Granta equipment is equipped with it). If you do not turn it off when removing the factory steering wheel, it may shoot out.
  4. Remove the steering wheel and install a horn on the adapter. The wiring must be stored in the adapter; to do this, carefully inspect all contacts.
  5. Connect the adapter to the shaft, but do not secure it with a nut.
  6. A sports steering wheel is installed on the adapter and secured with special screws.

You cannot throw away or sell the factory product; the sports version will raise questions when passing inspection.

Granta 2

The previous material is about checking the chassis and transmission.

We check the condition of the steering in accordance with the maintenance regulations after 15 thousand kilometers.

We carry out the work on an inspection ditch or overpass.

There should be no mechanical damage to the steering control elements.

To check the free play of the steering wheel (steering play), set the front wheels in a position corresponding to the straight-line movement of the car.

We attach a ruler or a screwdriver with a long shaft to the instrument panel with tape so that its blade is directed towards the steering wheel. We turn the steering wheel until the wheels begin to turn (the wheels must remain stationary), first in one direction and then in the other direction.
