Despite its simple and reliable design, the VAZ 2107 steering column is subject to wear, like any car parts and mechanisms. Over time, malfunctions may appear, of which creaking when turning the steering wheel is the most harmless. If problems are not identified and corrected in time, they may get worse. It may all end with the car stopping responding to turning the steering wheel. The probability of an accident in this case is almost 100%. Therefore, you should monitor the condition of the steering column and, if necessary, repair or replace it to ensure the absolute performance of this unit, which is critical for traffic safety.
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.
old and new
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.
Afterword
You will not have any difficulties when removing and installing the steering gearbox or cardan transmission. But it is worth noting that after all work on the steering, it is necessary to adjust the camber and toe of the wheels. This will save the tires and body. And don’t forget to fill the gearbox with transmission oil. This will allow the mechanism to operate as easily as possible. This is how the VAZ-2107 steering column changes. The price of a used part is 500-1000 rubles, depending on the condition.

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.
Procedure
The procedure is performed in two stages. The first is the removal of the VAZ 2107 steering gear:
- The machine is installed on a pit or a lift.
- The rod fingers are cleaned. Then the rods are separated from the bipod: first, the cotter pins and nuts are disconnected. Then the finger is simply squeezed out of its normal place.
- Now the intermediate shaft fasteners, which connect the mechanism to the steering wheel, are dismantled.
- Then you need to unscrew the three fastening nuts that secure the unit to the body, and you can remove the mechanism from the car. To make the operation easier, the bipod needs to be turned all the way into the body.
- Further, if individual elements fail, they are replaced on the desktop after complete disassembly:
- The gearbox is clamped in a vice, the bipod nut is unscrewed, and the rod is pressed off the shaft with a puller.
- Unscrew the filler plug, pour out the crater grease, unscrew the adjustment nut, and remove the stop washer.
- Remove the four bolts and remove the cover.
- Remove the screw from engagement. The cover can now be removed.
- The thrust shaft along with the roller is removed.
- The fasteners of the worm cover are unscrewed and it is dismantled along with the adjustment gaskets.
- With light blows of a hammer, knock out the shaft; it should come out along with the bearing.
- Use a screwdriver to remove the oil seal and use it to remove the seal.
- Using a tool and a hammer, remove the outer race of the 2nd bearing.
All elements are washed from contaminants and troubleshooting is performed.
Installation of a repaired or new VAZ 2107 steering gear is performed in the reverse order of dismantling the unit into the car. After completing the operation, you need to make adjustments.
For events you will need an assistant, as well as a screwdriver and a wrench 9:
- The car is installed on a flat floor, the wheels are straight;
- hood - open, remove the plastic casing over the screw used for adjustment;
- here you need to loosen the nut, which protects the screw from spontaneous movements;
- The assistant rotates the steering wheel in both directions, and the master achieves the optimal position in the hooks. It is clear that the steering wheel should have a small amount of travel, but it should be easy to rotate.
Also see the video for replacing the VAZ 2107 steering gear.
Note! To extend the service life of unit parts, it is necessary to reduce their friction against each other. Many car owners use the TAD-17 composition. But it is better to use gear oils with a viscosity of SAE85W90, SAE80W90 or SAE75W90. GL-4 or GL-5 has such indicators. The volume for refilling is 0.215 liters.
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.

Steering column device
The purpose of the steering wheel shaft ( steering
column) consists of transmitting torque from the steering wheel to the worm gear of the steering mechanism.
column
(injector), like similar units on all AvtoVAZ classic models, is rigidly attached to the car body using a bracket.
Structurally, the column
consists of a pair of hinges that can fold in the event of an accident. This ensures driver safety. To facilitate control, the upper shaft of the column rotates on a pair of needle bearings, the condition of which determines the force of rotation of the steering wheel.
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.
How does an electric booster work?
About replacing the rear axle gearbox of a VAZ 2107
The electric power steering on the VAZ-2107 starts to work and creates additional torque, which reduces the force required to turn the wheels. Moreover, it begins to work simultaneously with the driver turning the steering wheel. The device is able to reduce the load required to turn the steering wheel by 5.7 times.
In other words, if you applied a force of 20 kg before installing the device, then after that only 3.5 kg will be enough for a similar action. Stages of device operation:
- Using a torque sensor, it is determined in which direction the driver rotates the steering wheel.
- The control unit allows you to read all data related to engine speed and vehicle speed.
- Using an electric motor, the propeller shaft of the steering mechanism rotates. As a result, the force required to turn the steering wheel is reduced.
Using a speed sensor, a normal relationship is ensured between the gain of the device and the intensity of vehicle traffic. If the speed is low, it becomes harder to turn the steering wheel. Therefore, the control unit understands that the gain needs to be increased. Conversely, if you are moving at high speed, then you need to apply less force. Therefore, the electric power steering is not involved in steering.
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

Replacing the steering shaft
Remove the negative terminal from the battery. Remove the steering wheel, steering shaft mounting bracket covers, steering column switches, disconnect the ignition switch connector
Using a 13mm wrench, unscrew the nuts from the coupling bolts of the intermediate shaft universal joint forks and remove the bolts.
Using a 10mm wrench, unscrew the two shear screws securing the steering shaft bracket.
If the bolts have their heads cut off, then use a chisel to loosen the tightening of the remaining round heads and finally unscrew them with pliers. Locking washers are installed under the screws. Using a “13” wrench, unscrew the two nuts securing the steering wheel bracket......and remove the bracket. Remove the upper shaft from the splined joint with an intermediate shaft. Remove the intermediate shaft from the splines of the gearbox worm shaft. Flare the curved edges of the bracket pipe on the steering wheel side, insert the key into the ignition switch and turn off the lock. With light blows we knock the shaft together with the bearing out of the pipe.
The second bearing can be knocked out using a suitable piece of pipe. The needle bearings are installed in shock-absorbing plastic cages. If the shaft or its bearings are worn or damaged, replace them.
Install the steering shaft in the reverse order of removal. Before finally tightening the steering shaft bracket, turn the steering wheel in both directions several times to self-install the bracket.
If it is necessary to remove only the steering gear reducer, unscrew the bolt securing the lower end of the intermediate steering shaft to the worm shaft and the bolts securing the gearbox to the body side member.
Install the steering shaft in the reverse order of removal.
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.
Photo of the VAZ 2107 steering gearbox
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.
Required Tools
To repair the VAZ 2107 steering gear or replace it you will need:
- set of wrenches;
- beard;
- screwdriver;
- hammer;
- vice;
- mandrel or similar-sized pipe section;
- rags.
Independent work is completely justified economically, since as of March 27, 2022, replacing a unit in car services costs an average of 2,400 rubles. Plus 450 rubles for adjustment. So the work costs as much as a new gearbox.
But you should start working only if the car owner clearly understands how to repair the unit. Below is the sequence of operations in the text.
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.
When should you shoot?
- Signal button malfunction
. This also doesn't happen often, but it can happen. In this case, it is simply impossible to use a sound signal. The problem occurs due to a fallen contact, but it is almost impossible to restore it due to its inconvenient location; - Appearance
. Over time, the steering wheel gradually wears out, so drivers often use braids. But not all drivers like to use them in practice. They increase the thickness of the rim, which is not convenient for all people. If you do not use braid, the steering wheel loses its appearance, as it is constantly in contact with your hands; - Tuning
is another case when it is still necessary to remove the installed steering wheel; - Also, the steering wheel can be dismantled if repairs are necessary, during which this part will interfere. For example, when replacing a column, you simply cannot do without removing the steering wheel. It can also interfere with some types of work with a panel or dashboard.
Steering linkage VAZ 2107, its purpose and replacement
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:

- 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.
SELECTION OF NEW TRAPEZE PARTS
Since the VAZ 2107 car has been discontinued, finding original spare parts is becoming increasingly difficult. On the roads of the CIS countries, steering rods fall into disrepair quite often, so the supply of “original” parts has long been exhausted. In recent years, trapezoid kits have been supplied to the market by several well-known manufacturers:
- "Belmag";
- "Cedar";
- "Track";
- Fenox;
- Delphi;
- "VIS".
Complete kit includes rods, clamps and castle nuts with cotter pins
The quality of steering rods from these manufacturers is approximately the same, as evidenced by reviews from car enthusiasts on the forums. Therefore, choosing a new spare part comes down to following 3 rules:
- Beware of fakes and do not buy parts from dubious outlets.
- Avoid tie rods from unknown brands sold at bargain prices.
- Do not confuse the left long tip with the right one if you are changing part of the trapezoid.
