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.
↑ Removing the steering mechanism from the car
- Disconnect the wires from the battery and remove the horn switch trim using a screwdriver.
- Remove the steering wheel.
- Remove both halves of the steering shaft cover.
NOTE! If it is necessary to remove only the steering gear housing, unscrew the bolt securing the lower end of the intermediate steering shaft to the worm shaft and the bolts securing the housing to the body side member.
- Remove the instrument panel and disconnect the plug blocks of the three-lever switch from the plug blocks of the wire harness.
- Disconnect the wires from the ignition switch terminals by unscrewing the fastening screws and pushing in the lock latch, remove the ignition switch.
- Loosen the clamp securing the housing of the turn signal switch, headlights and windshield wipers and remove it.
- Unscrew the bolt securing the lower end of the intermediate shaft to the steering gear worm shaft.
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.

- Remove the steering gear housing by first unscrewing the bolts securing it to the body side member.
- Unscrew the screws securing the steering shaft seal and remove it.
Adjusting the VAZ 2101 gearbox
Adjusting the VAZ 2101 gearbox consists of one thing - reducing the steering play. This is done quite simply; you do not need to know the structure of the steering gearbox from the inside. Just look at it from the outside and see that on top there is one large screw (adjusting) and one small one (for filling oil and controlling its level).
Adjustment procedure
When adjusting the VAZ 2101, the help of a second person will be required. However, you can do everything alone, because even replacing a column on a penny turned out to be within your power. Completely unscrew the nut that is located on the screw and is necessary to secure it.
You try to tighten the screw with a screwdriver, when it refuses to go any further, your partner should pull the steering wheel in different directions. And the bolt will go easier. The steering gearbox on the VAZ 2101 is adjusted until the play is acceptable. At the end, the nut is tightened and the car is ready for further use.
↑ Installing a steering gear on a car
Having secured seal 2 to the front panel, install the steering gear housing onto the side member without fully tightening the nuts of the housing mounting bolts.

Use a special device to orient the crankcase so that the angle “a” does not exceed 32°, and the gap between the shaft and the brake pedal is at least 5 mm. Then fully tighten the crankcase mounting bolt nuts.
Steering knuckles
The most reliable element in the VAZ-2107 steering device is the steering knuckle. It is durable and very strong, but when repairing the suspension it sometimes has to be removed. The steering knuckles hold the wheel hubs. This element is fixed on the lower and upper arms using movable ball joints.
When turning the steering wheel, the gearbox uses levers to turn the fist in the desired direction. This ensures that the car turns in the desired direction. The elements are made of cast iron, so they can easily withstand high loads. One of the most common breakdowns is deformation from strong impacts on the suspension, from driving on uneven roads and after an accident. The following symptoms may also appear:
- Increased play due to a broken hub bearing and severe wear on the knuckle axle.
- Uneven or rapid tire wear.
- When driving on a flat road, the car gradually moves to the side.
Uneven tire wear can be caused by incorrect wheel alignment. Therefore, before blaming the steering knuckle for all the troubles, you need to carefully diagnose the entire front suspension. It is quite possible that there is excessive wear on the silent blocks or tie rod ends.
↑ Section of the steering gear housing
1 — plate of the adjusting screw of the bipod shaft; 2 — bipod shaft adjusting screw; 3 — adjusting screw nut; 4 — oil filler plug; 5 — steering gear housing cover; 6 - worm; 7 — steering gear housing; 8 — bipod; 9 — nut securing the bipod to the shaft; 10 — spring washer; 11 — bipod shaft seal; 12 — bipod shaft sleeve; 13 — bipod shaft; 14 — bipod shaft roller; 15 - worm shaft; 16 — upper ball bearing; 17 — lower ball bearing; 18 — adjusting shims; 19 — lower worm bearing cover; 20 — roller axis; 21 — roller ball bearing; 22 — worm shaft seal; B, C - marks.
- Set the bipod of the steering mechanism to the middle position, for which align the marks on the crankcase and on the worm shaft (see figure).
- Temporarily install the wheel on the shaft so that the spokes are horizontal and in this position connect the universal joint fork of the intermediate steering shaft with the worm shaft, then attach the steering shaft bracket to the body.
- Remove the steering wheel and install the turn signal, headlight and windshield wiper switch onto the steering shaft.
- Place the steering wheel on the shaft in its original position and, pressing the steering wheel, as shown by the arrows in Fig. check that there is no radial movement of the shaft. If there is radial movement, replace the upper steering shaft or bearings.
- Check that the steering wheel rotates smoothly and easily in both directions, then tighten the steering wheel nut and tighten it at three points.
- Slide the housing of the turn signal, headlight and windshield wiper switch towards the steering wheel until it stops and tighten the switch mounting clamp.
- Connect the wires to the ignition switch terminals and secure the switch with screws to the steering shaft bracket.
- Connect the turn signal, headlight and windshield wiper switch connectors to the car wiring harness connectors.
- Place the two halves of the facing casing on the shaft and fasten them with screws. Install the horn switch on the steering wheel.
- Install the middle and side left link ball pins on the bipod and secure them with nuts.
- Adjust the toe-in of the front wheels and check the force on the steering wheel, which when turning the wheels on a smooth plate should not exceed 196 N (20 kgf) (when measured at the wheel rim).
NOTE! You can separately assemble the steering shaft with the turn signal switch, headlight switch and steering wheel, and install this unit on the car.
To secure the assembly, position the steering wheel spokes horizontally and connect the worm shaft to the lower end of the steering intermediate shaft.
Having not fully tightened the bracket mounting bolts, turn the steering wheel in both directions several times, then tighten the bracket mounting bolts.
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.

Budgetary, but unique improvement of the steering control of the VAZ-2107
Introduction
The VAZ-2107, to which thousands of compatriots are accustomed, is inferior in several respects to its foreign counterparts, which is why motorists who want to improve the characteristics of their own car do their own tuning of the VAZ-2107 steering. A thoughtful and correct tuning solution can be considered the installation of a hydraulic booster or electric power steering. Thanks to competent modernization, a unit will appear in the car, through which additional force is created on the wheels when entering a turn. The improvements made will bring domestic cars closer to the class of more expensive foreign cars.
The structure of the steering rack and mechanism of the VAZ 2107
Steering tuning
Tuning the VAZ-2107 steering can begin with a well-founded decision to replace the factory steering wheel with a sportier device with a diameter of 320 mm. Such a unit will give the car owner many advantages: firstly, he will be able to park with greater maneuverability. When upgrading the steering wheel, do not forget about installing a safety glass.
Those motorists who prefer sports tuning (low-number rack) should be prepared to pay twice as much money for the unit than for a simple standard device. However, after installation, the car will be able to turn the wheels in just two steering turns.
The third step to improve the car could be adjusting the camber and toe. Experts who have been working with different VAZ models for many years increase toe-in and negative camber on the front axle
At the same time, it is imperative to pay attention to the toe-in of the rear wheelbase, which should, on the contrary, decrease
Installing power steering
If a motorist wants to install power steering on a VAZ-2107 with his own hands, which the manufacturer did not consider necessary to install in one of the most budget cars in the whole world, he can take one of two possible paths. Firstly, you can select the optimal steering rack that has power steering and then decide on its further location in the car. True, such an action will require enormous labor and money. Secondly, which is more expedient, you can buy a ready-made kit at an auto parts store that allows you to perform all possible most useful manipulations on the stationary steering rack.
The purchased power steering for a VAZ-2107 will consist of many parts: a pump, a pulley, a steering gear, a hydraulic cylinder, an expansion tank and a hose system.
To install power steering on a VAZ-2107, you need to start with a pump, through which pumping is carried out and a certain pressure is created in the unit. This pump must be placed on the cylinder block, since it will operate due to a belt drive. The next step is to determine where to install the crankshaft pulley. Then the steering gear is replaced. The car owner should check the size of the purchased device in advance, since it will most likely differ from the factory analogue, which may require modification of the installation location of the device.
When installing power steering in your car, you should pay close attention to the hydraulic cylinder, which should be located in the car according to the instructions. Further modernization consists of the location of the expansion tank and the sequential connection of a set of parts with high-pressure hoses. The installed reservoir must be equipped with a special fluid intended directly for the power steering. As a result of the manipulation, it is worth pumping the system.
