Many domestic car enthusiasts, including owners of the VAZ "Seven", are familiar with such a steering defect as steering wheel play. It is especially clearly felt when the car is moving at high speed in a straight line. The generally accepted way to identify the symptoms of this malfunction is to sharply turn the steering wheel. If it (the turn) is accompanied by a knock, there is play in the VAZ 2107 steering wheel.
The article brought to your attention will discuss the sequence of actions performed in the process of checking the technical condition of the steering mechanism, as well as when carrying out adjustment measures.
Replacing the steering column or gearbox
Hello again. Thanks everyone for the advice on the steering column.
After reading the information about the repair, I realized that it was not worth the money.
The best option was to purchase a used column in good condition, because... Knowing about the current quality, many will understand me. During the survey, it turned out that Private838
has a normal steering column, which is what I wanted to take.
My grandfather also found out about the problem, and it turned out that a friend of his from the garage had a five-piece gearbox in superb condition. Actually, I got it for myself for seven. For installation I used a steering wheel end puller. The most stressful thing was to unscrew the 3 bolts that secure the gearbox to the body, which was very inconvenient for me personally. In the process, we had to additionally remove the adsorber, the control center, unscrew the locker, remove the wheel and unscrew the cardan from the column shaft
.
the puller is in use, the steering rods are in excellent condition
this is where the oil was flowing, but it was still normal in the gearbox
Oil was also leaking through the side cover.
After comparing the old and new ones, it turned out that my gearbox was a little tight to spin behind the bipod, but with the new one everything was fine. The adjusting screw in my column was recessed flush. The new one stuck out about 4 mm.

you can see how much the regs are screwed in. screws
place where the cardan is disconnected from the shaft
Then I put everything back in place. In order not to calculate the position of the steering wheel, which was not deployed correctly, I simply removed it and put it in place. I left the old oil in the column because it was yellow. I just topped up a few cubes of Lukoil mineral water.
everything is collected
syringe and oil
Result. After adjusting the steering wheel and driving around, I realized that the controls had changed beyond recognition. If earlier on bumps the steering wheel sat gently in your hands, now it began to be knocked out. On a flat road he stands straight and does not move. Previously, he was wobbling in all directions. In general, I'm pleased.
Among the tips for improving the service life of the speaker, I can say:
1. It does not need to be tightened when adjusting; there should not be much play. 2. Do not turn the steering wheel in a place where it is difficult to turn (asphalt and other surfaces where there is more friction).
Good luck to everyone, may the quality of spare parts be with you!
Installation and repair of the steering column on a VAZ 2107
One of the elements of the VAZ 2107 car, which received a number of improvements in this model compared to the previous ones, is the steering column.
How is its device different? In the VAZ 2107, the steering column shaft consists of two parts connected by a cross. Thanks to this design, driver safety is significantly increased, since in the event of a collision the shaft simply bends at the hinge joint and does not cause serious harm to the person. Also, the shaft in the VAZ 2107 has bearings, so turning the steering wheel requires much less effort. The steering column of the VAZ 2107 consists of a shaft with an articulated joint and a gearbox with a worm gear. Column repair is a very rare occurrence. If you ensure timely maintenance of this unit, it may never be needed. Steering column maintenance work includes lubricating the steering shaft joint, tightening the steering wheel nut, changing the oil and adjusting the gearbox. Let's look at possible problems associated with the steering column and methods for eliminating them.
Brake calipers
In a number of car models equipped with disc brakes, the rear brake calipers come loose or play. This is the most common problem with any budget car. Budget fasteners often lead to parts breaking. Diagnostics of calipers is carried out using the following actions:
- twitching of the caliper with your hands when the wheel is installed - everything needs to be screwed securely;
- removing the wheel and conducting manual diagnostics of all its fastenings, twitching the mechanism with your hands to determine the absence of play;
- if you have experience, disassemble the caliper in order to determine the released parts;
- paying special attention to the quality of tightening of each module and bolt;
- Checking the pad for wear or bending.
If the brake system is a drum type, everything is much simpler; in this case, no mechanism will ever make a knock. The only exception is the scattering of the entire brake drum, flying out of the pads and other parts. This can only be verified by disassembling the entire mechanism.
STEERING WHEEL PLAY
The appearance of steering play can be caused by two reasons. First, the nut securing the steering wheel to the shaft is loosened. If the nut is not tightened promptly, the splines on the handlebar and shaft will become damaged over time and one of these parts may need to be replaced. The second reason may be wear of the worm gear. To eliminate this malfunction, a special device is provided - an adjusting bolt with a lock nut.
In order to adjust the worm gear, the nut is released, the screw is turned using a screwdriver until the backlash is eliminated, after which the nut is tightened to prevent spontaneous unscrewing. If it is impossible to eliminate the backlash by adjustment, it means that the gearbox needs to be repaired and the worm pair replaced.
To prevent premature wear of gearbox parts, periodic monitoring of the oil level and its replacement is recommended. Level control is carried out as follows:
- Using a 8 key, unscrew the filler plug;
- Use a screwdriver or other object to check the oil level. It should be level with the bottom edge of the filler hole.
- If necessary, add oil using a special supercharger until it begins to flow out of the hole.
To change the oil, unscrew the screws securing the gearbox cover, having previously placed a container under it to collect used oil. Since complete removal of the cap is not required, it is moved to the side and the oil is drained. This operation is best performed on a hot engine. Warm oil has greater fluidity and drains faster. After all the oil has drained out, the cap is screwed into place and new oil is poured into the gearbox using the method described above.
Quick Guide
The main reason for tapping is the formation of a gap in the joints. In the steering system, there may be knocking on the tips, ball joints of the rods, the rack, the “cardan” in the column, the steering wheel on the shaft, or the auto-folding system in case of an accident. The metallic sound is distinct and can be heard in place when rocking the steering wheel.
It is quite possible to mistake problems in the suspension for problems in the steering, since the initial stages of wear of bearings and supports only make themselves felt when cornering at speed. In the suspension part, the cause of the knock should be sought in the wheel bearings, ball joints and “supports”.
REMOVAL OF THE GEARBOX
The design of the gearbox does not allow it to be repaired without removing it from the vehicle. In order to remove it, you must:
- Disconnect the tie rod ends from the gearbox. First, they are uncoiled, then the nuts are unscrewed with a 22 wrench and the tips are pressed out using a special puller.
- Unscrew the clamp securing the steering shaft to the gearbox.
- Remove the three bolts that secure the gearbox to the car body.
The gearbox design should not cause any particular difficulties when repairing it. You just have to take into account that the worn elements, called the worm pair, are both replaced at the same time. After this, adjustments must be made.
Elimination
The fight against backlash should begin by checking and tightening all threaded connections. Often this is the reason. Particular attention should be paid to the nut securing the column to the gearbox. With frequent trips on dirt roads and worn-out asphalt, this fastener regularly becomes loose. If you do not respond to the problem in a timely manner, you risk getting more serious steering problems. The nut may unscrew entirely, leading to complete failure of the steering. This also leads to increased wear of all parts of the mechanism.
Adjusting the gearbox also helps combat backlash. To do this you will have to look under the hood. There you will see a gearbox. There is an adjustment screw on it. To get to it, you will have to remove the plug. The screw is protected from turning with a 19mm locknut. It is slightly loosened with an open-end wrench. After this, adjustment is made with a screwdriver. The task is to reduce the backlash. If you can’t do this, then it’s time to change the gearbox. It's easier to do the job with two people.
Steering mechanism VAZ 2107
VAZ cars, which are classic models, are distinguished by pleasant reliability. This also applies to the steering mechanism.
It is quite complex, but its design allows you to maneuver and ensure reliable vehicle control even in the most difficult road conditions.
The modernization process led to the installation of a composite shaft and a safety column. Due to the size of the steering wheel, the driver makes the necessary maneuvers without any problems. From lock to lock, it takes 3.5 turns to turn the steering wheel completely. The force from the steering column is transmitted to the drive via a composite shaft.
The current steering mechanism on the VAZ 2107, a product of the Volga Automobile Company, is quite informative and does not allow the driver to get tired during long trips. There are certain difficulties when turning in a parking lot, but as soon as the car begins to move, the resistance weakens and turning the steering wheel becomes easier.
There is one more nuance - when the steering mechanism is working properly, there is a slight play. But its limit value complies with the traffic rules. This is due to the fact that there are steering rods on the VAZ 2107 and an impressive number of elements in the gearbox.
In general, the steering of the 7 can be considered reliable.
Diagnostics
How to remove steering play on a VAZ 2107? The question is quite complicated. After all, there are 2 types of this problem:
- Axial
- manifests itself when the splines are poorly connected or there are problems with the gearbox; - Longitudinal
, appears when the bracket wears out.
No special testing is required to determine the presence of play. You will understand this immediately after its appearance. The amount of play is checked at the service station with a special device - a play meter. But such devices are quite rare in garages. Therefore, another method is usually used. For this you will need an assistant. He will turn the steering wheel, and you must track the moment the wheels begin to react (turn). Normal play should not exceed 10°. Anything higher is a sign of a problem.
Mechanism design
To repair the steering column on a VAZ 2107, you first need to understand its structure, as well as the principle of operation.
The seven is in many ways similar to the “penny”. Therefore, the device and design received minor changes. The structure includes:
- A mechanism that transmits the driver’s force to the executive components;
- A steering drive that turns at an angle specified by the driver.
In turn, the steering mechanism consists of:
- Composite shaft with cardan transmission;
- Steering wheel (steering column together with a steering wheel with a diameter of 520 mm);
- Worm gearbox of the VAZ 2107 steering mechanism.
The control system has the following components:
- Bipod;
- Pendulum arm;
- Swivel arms;
- Steering rods for VAZ 2107 (one middle, two side).
The outer rods include two parts, which allows you to change their size by adjusting the toe angle.
Tie rod/end set for VAZ 2107
The operating principle of the steering mechanism looks like this:
- The driver begins to rotate the steering wheel, the wheel size of which ensures that this task can be performed quite simply;
- By means of a composite shaft, a worm gear is activated, which reduces the speed;
- The steering mechanism is lubricated with special oil (TAD 17) poured into the gearbox;
- The worm gears rotate, which causes the double ridge roller to move;
- This, in turn, causes the secondary shaft to rotate;
- The tray mounted on the secondary shaft makes a turn and pulls the rod system behind it;
- These components influence the levers that synchronously rotate the wheels to the required angle specified by the driver.
Parts of the steering gear housing: 1 - housing; 2 - bipod; 3 — lower crankcase cover; 4 — adjusting shims; 5 — outer ring of the worm shaft bearing; 6 — separator with balls; 7 — bipod shaft; 8 - adjusting screw; 9 — adjusting plate; 10 — lock washer; 11 - worm shaft; 12 — upper crankcase cover; 13 - sealing gasket; 14 — bipod shaft sleeve; 15 — worm shaft seal; 16 — bipod shaft seal.
Steering column parts: 1 — steering gear housing; 2 - shaft seal; 3 - intermediate shaft; 4 - upper shaft; 5 — fixing plate of the front part of the bracket; 6 — bracket for fastening the steering shaft; 7 - upper part of the facing casing; 8 — bearing sleeve; 9 — bearing; 10 — steering wheel; 11 — lower part of the facing casing; 12 — bracket fastening parts
Repair and maintenance
Over the years of operation it has been proven that the steering on VAZ 2107 vehicles has impressive reliability. However, this does not take away the fact that the machine requires periodic inspection and repair.
- When performing maintenance, it is important to check for increased play as well as increased wear on the ball joints. To do this, you need to turn the steering wheel from one side to the other. If the wheels do not respond when the steering wheel is turned 5 degrees from its original position, this indicates severe wear. Here you will need to repair the steering column on a VAZ 2107.
- To avoid the need for urgent and rather expensive repairs of the steering gear on a VAZ 2107, it is necessary to change the oil in the worm gear housing. This is done at intervals of 60 thousand kilometers. Leaks may occur through the seals, so they are carefully checked 2-3 times a year. This is one of the weak points of the system.
- The swing arm should be inspected by slowly rotating the steering wheel from side to side. If the parts move in a vertical plane, then surgical intervention is required.
If any malfunctions are detected, the breakdowns should be repaired immediately.
To do this, the drive and steering mechanism are dismantled completely or partially. Everything depends directly on the nature of the breakdown.
Check which parts have defects and what has failed. Inspection is required for each component of the mechanism. If parts are worn out, there is no point in trying to repair them. There is only one way out - a complete replacement of worn-out components of the steering system on a car from a Volga company.
If problems arise with the steering, it is advisable to contact a professional service station.

You can replace the gearbox yourself, but the process is complicated and requires at least minimal experience and skills.
The VAZ "Seven" is a true classic of the domestic automotive industry. Unlike modern LADAs, they are more reliable and durable, which is proven by the huge presence of these cars on our roads.
Of course, the VAZ 2107 has long been outdated, it does not have a hydraulic booster, and you have to apply sufficient force to turn and maneuver. But for connoisseurs this is not a problem.
Sound criteria
There are plenty of reasons why the engine knocks. Some knocking noises only indicate minor problems that can be easily diagnosed and corrected during the next inspection. But there are a number of sounds that very clearly indicate that there are serious problems with the internal combustion engine that require immediate intervention in order to avoid the occurrence of many unpleasant situations, such as, for example, a major engine overhaul.
The occurrence of any sound occurs due to the fact that one element of the internal combustion engine hits another, and each of the impacts can have its own individual sound coloring, intensity, duration and frequency.
A sound of medium volume and intensity indicates a more serious problem. In this case, the first thing you need to do is go to the nearest car service center to avoid serious engine damage.
If the sound marker has a clear, loud sound color, then the car owner urgently needs to turn off the engine and call a tow truck. When moving independently, the motor may knock.
How much does a steering column cost for a VAZ 2107
The cost of a VAZ 2107 steering column in Russia varies from 1,450 to 4,449 rubles .
The steering column of the VAZ 2101-2107 family is a mechanism for transmitting natural force from the steering wheel to the wheels through rotational actions. Inside the column, the steering shaft contacts another gear, forming a worm pair, which, in turn, transmits force to the steering linkage. Inside the case, which is made of silumin (does not oxidize when in contact with liquids), there is an oil bath. The efficiency of the mechanism is also achieved thanks to the following components (included in the repair kit):
- Adjustment screw.
- Worm bearing.
- Stuffing box.
- Bipod shaft bushing.
- Bipod shaft seal.
- Adjusting shim.
- Bipod shaft roller thrust washer.
It is best to buy an original steering column, which differs from analogues not only in the cost of 1,100-1,430 rubles. , but also design features. We are talking about fastenings to the body. These are tear-off fasteners or shear bolts, which, in the event of an accident, will protect the driver from injury from the steering column. In addition, the original speakers 21050-3400010-00 for Lada 2101-07 and a dry weight of 5 kg have reinforced threads on the shaft, which do not deform during shocks from the suspension and other operational features.
What affects the cost?
The cost of a steering column is influenced by the following factors:
- Manufacturer.
- Country of origin (Eurasian compliance standards).
- Type of component.
- Type of equipment.
- State.
- Brand.
- Type of spare part.
- Type of modification (without hydraulic booster).
- Model.
- Serial compatibility.
In addition to such key parameters, the cost is also affected by the type of packaging and internal placement of the product. Original steering columns, which have a clear centering position with a noticeable effort to overcome it, regardless of the direction of rotation, are always equipped with an output shaft mounting bipod. The latter prevents its rotation and axial displacements in the bearing and oil seal. Also, the original AvtoVAZ packaging is different:
- Complete with technical data sheet and warranty card (separate sealed bag).
- Security seal with laser engraving on the top and bottom.
- Since February 2016, compliance with Eurasian standards is indicated on the side of the box, instead of specifications.
Also included in the price is the oil used to fill the steering column. During transportation, the adjusting bolt and gasket are in a free state, which requires compliance with the orientation of the product in space.
Types and prices
The original steering column for passenger cars of the VAZ 2101-07 family has catalog number 21050-3400010-00 . Its cost varies from 2,172 to 4,449 rubles . In order for the classification of goods to be as complete as possible on the part of the buyer, the price can be divided by series and compatibility. The latter looks like this:
- VAZ 2102, 1973-1985 – 2,797-4,449 rubles.
- VAZ 2103, 1972-1984 – 2,797-4,449 rubles.
- VAZ 2106, 1975-2006 – 2,430-4,300 rubles.
- VAZ 2101, 1970-1988 – 2,172-4,301 rubles.
- VAZ 2106, 1975-2005 – 2,430-4,250 rubles.
- VAZ 2104, 1984 – 3,934 rubles.
- VAZ 2105, 1981 – 4,012 rubles.
- VAZ 2107, 1982-2012 – 2,640-4,449 rubles.
- VAZ Niva (2121), 1976 – 2,970-4,440 rubles.
- VAZ 2121, 1994-2006 – 2,970-4,440 rubles.
- VAZ 21213, 2001-2006 – 2,700-4,449 rubles.
If we take into account the gradation by series, the pricing policy is as follows:
- 2101, 1970-1988 – 1,450-4,449 rubles.
- 2106, 1975-2005 – 2,797-4,449 rubles.
- 2107, 1982-2012 – 2,400-4,449 rubles.
Prices are given for original AvtoVAZ products and their copies in similar packaging, configuration, as well as manufacturer’s warranty. Each of the items contains oil in the crankcase of the lubrication system.

(07.11.2009, 20:53) ———————————————— I pulled the steering rods. It seems that the left thrust is still knocking. But damn, when you drive, the knock is louder than when you just pull it. Is this how it should be?

(08.11.2009, 00:25) ——————————————— By the way, I used to have alloy wheels on summer tires, now I have winter tires on simple wheels. On the casting, the bolts were longer than the simple ones, and I also put them on the dies. What do you think they might be talking about there?
