If at some point the car cannot turn in the right direction, then it cannot be called safe. This applies to all cars, and the VAZ 2106 is no exception. The steering system of the “six” is characterized by increased complexity. The heart of the system is the steering gear, which, like any other device, becomes unusable over time. Fortunately, a car enthusiast can easily change it himself. Let's figure out how this is done.

The design and principle of operation of the VAZ 2106 steering mechanism
The design of the VAZ 2106 steering mechanism is very complex. However, it is precisely this that allows the driver to confidently control the car in a variety of situations. All elements of the control system are shown in the figure below.
The control system of the “six” is very complex and consists of many elements
Here it should be said about the ease of control of the “six”. To turn the steering wheel, the driver makes a minimum of effort. And therefore, less tired on long trips. The steering of the “six” also has one more feature: play. It is very minor and is not a sign of a problem with the steering system. Play in the “six” steering wheel is a common occurrence; it occurs due to the abundance of various rods and small elements in the control system. Finally, in the latest models of the “sixes” they began to install injury-proof steering columns, which could fold in the event of a strong impact, increasing the driver’s chances of surviving a serious accident. The VAZ 2106 steering mechanism works as follows:
- The driver turns the steering wheel in the desired direction.
- A worm shaft begins to move in the steering gear, driven by a system of hinges.
- The gear mated to the worm shaft also begins to rotate and moves the double-ridge roller.
- Under the action of the roller, the secondary shaft of the steering gear begins to rotate.
- The bipod is attached to this shaft. When moving, they set the main steering rods in motion. Through these parts, the driver’s force is transmitted to the front wheels, which rotate to the required angle.
How to change the oil in the rear axle gearbox on a VAZ 2101-VAZ 2107?
Draining: 1) Firstly, the oil needs to be warmed up, the heated oil flows out faster, and also all the dirty particles from the inside of the gearbox housing peel off and mix with the oil, thereby you will pour out all the oil and all the dirt that is on the walls of the gearbox housing (Crankcase the gearbox is the place where the oil is located), in order to warm up the oil, start the engine of the car and let it run for a while, as soon as the engine temperature arrow shows the operating temperature, stop warming up and turn off the engine of the car, at this moment the oil in the gearbox will heat up to quite high temperature (About 75-90 degrees), so be careful when you drain it so you don’t get burned.
2) Now stock up on some kind of metal brush and use it to wipe the filler plug and drain from dirt, you don’t have to do this, but if you have a brush at hand, then follow the advice, after this operation, unscrew the drain plug and when you feel that the plug is already there When it comes out, put the hex key aside and unscrew this same plug by hand as shown in the photo below, keep in mind that after you unscrew the plug, oil will flow out of the hole it covers, so immediately prepare an empty container for draining.
Note! If you want to more thoroughly pour out all the oil and all the dirt from the gearbox, then slightly lift the right rear part of the car with a jack, thereby the car will fall onto the left side (In the direction of travel of the car) and all the oil will drain out of the gearbox better, since there are drainage holes not located directly below, but slightly to the side (you can see this in the small photo below)!
3) Next, wait until the oil has all drained and, having wiped the drain plug dry from all dirt (the most important thing is to wipe it inside, you don’t have to really wipe it outside), screw it back into place, then pay attention to the drained oil from the gearbox, it shouldn’t be there may be obvious metal shavings (If there are, this is very bad, in this case, change your driving style since the gears in the gearbox cannot withstand such loads and crumble a little, or just change the oil in a timely manner) silvery dust may be visible, but this is also not very good but it’s better than clearly visible metal shavings, and if you have coffee-colored oil leaking out, this may indicate that the gearbox on your car is not sealed and water gets into it, mixing with oil, and it gives the color of coffee (Cars that are all winter or just stood in an unheated garage for a long time, in this case condensation forms inside the gearbox housing which turns into water mixing with oil), and the most common color is simply black, the oil can change to this color if you poured it into a dirty gearbox (It’s just that the gearbox sometimes still needs to be washed to remove all the dirt, read about how to do this in the article: “Washing the rear axle gearbox on VAZ cars”), also over time the oil can change color to black when it is all additives will disappear and it will no longer be able to protect and lubricate the gearbox.
Filling: After the plug is screwed in, proceed to pouring the oil. To fill, you will need a special syringe that can be bought at a car store, but if you have a bottle with a very small neck, then you can use it. To fill, unscrew the filler plug in the gearbox (Remember , we indicated the location of the drain and filler plugs earlier in the drawings) and pour oil through the holes, you need to pour it until it begins to pour out through the filler hole, so as soon as it starts to come out back, stop pouring the oil and screw the plug back onto your place and all the way.
Note! Let's add a little to the article, there is still a breather on top of the gearbox (it is indicated by an arrow) it should move easily and without any extraneous jamming, so rotate and also press on it, by the way, if it does not work, then oil through the seals can easily begin to squeeze out when the gearbox will warm up (The higher the temperature of the gearbox, the more pressure is created inside it), read more about this breather in the article: “Replacing the rear axle gearbox oil seal on cars”!

Purpose of the VAZ 2106 steering gear
The steering gearbox is an integral part of the “six” control system. And its purpose is to ensure timely rotation of the steering wheels in the direction desired by the driver.
The steering gearboxes of all “sixes” are made in cast steel housings
Thanks to the steering gearbox, the effort that the driver spends turning the front wheels is significantly reduced. And finally, the gearbox allows you to reduce the number of steering wheel revolutions several times, which significantly improves the vehicle's handling.
Steering gear design
All elements of the steering gear are housed in a sealed steel case, which is produced by casting. The main parts of the gearbox are the gear and the so-called worm. These parts are in constant engagement. The housing also contains a bipod shaft with bushings, several ball bearings and springs. There are also several seals and gaskets that prevent oil from leaking out of the housing. You can learn more about the details of the “six” gearbox by looking at the figure.
The main link of the “six” gearbox is the worm gear

If you solve the problem, please write back. And so the advice is to lift the front of the car with jacks and try to turn the steering wheel
I also heard that the steering rack from the VAZ 2110 is put on high quality.
I poured an engine additive into the column and the steering became a little lighter.
Check the pendulum on the right side, they sometimes jam. When I changed mine, I couldn’t turn it by hand, which couldn’t be said about the new one.
Oil is not the reason, the main thing is the level, and what kind is not important, even engine oil, as long as there is some kind of oil.
Level at the top filler plug
Strengthen your arm muscles. Seriously. Nothing else can be fundamentally changed. I drove different cars, including various Zhigulis and PP Vases. Well, you can’t do anything with a system like a globoidal worm. This steering mechanism is reliable, but generally tight. The most effective tuning method is installing an EUR. But it's difficult and expensive. Good pressure in the tires of the front wheels will make driving a little easier, oddly enough. Well, replacing the pendulum, of course.
Nevermind, the steering wheel should turn easily in place.
What is easy to eat? In what numbers should it be measured? This is a subjective, relative feeling. For a couple of months I simultaneously drove a VAZ 2101 with a working steering wheel and an almost new VAZ 2113. On a penny, the steering wheel turned easily. But at 2113 the steering wheel was turned almost by the power of thought! As it seemed to me.
Well, for example, with women's hands without strain and excessive effort. If it’s hard for men, then it’s a malfunction.
I agree here. Usually the driver senses that something is wrong. A good option for checking is another, exactly the same car. My friend also has a six. I drove it for a drive and immediately realized that my clutch was faulty.

Tire pressure 2.0 in all. And you need to think about the pendulum
EUR is cool and wonderful. You can get a used one for 5 thousand. But it’s better not to buy a used one. I thought about putting it. But personally, I'm bored. Suddenly you mess up a little and it will refuse at a speed of about 100...

EUR from the same Priora costs about 20 rubles
Sometimes I pump it up to 2.1. It's fine if you drive on more or less decent roads. I didn’t think about the pendulum: I just replaced it with a new one and immediately installed the steering rods as a set. When changing the oil, was the OLD oil still in place or did it leak out?
I pumped out 100 grams with a syringe, maybe it worked. And the norm according to the manual is 210 grams.
EUR from the same Priora costs about 20 rubles
I bought it for 3500 once.
And from what car? If there is an option to find an inexpensive EUR complete set, then I’m ready to buy
I'll look at the steering column assembly from Priora.
The oil never changes there at all. Possible alignment of the curve.
Signs of breakdown of the gearbox and other elements of the steering system
The steering gearbox on a VAZ 2106 very rarely fails alone. As a rule, a gearbox failure is preceded by the failure of several elements of the steering system, after which the gearbox itself breaks down. That is why it is better to consider the problems of this system as a whole. We list the most well-known signs of a breakdown of the control system on the “six”:
- when turning the steering wheel, a characteristic grinding or loud creaking sound is heard from under the steering column;
- the driver observes a constant leak of lubricant from the gearbox;
- turning the steering wheel began to require more effort than before.
Now let’s look at what exactly can cause the above symptoms and how to eliminate them.
Steering system noise
Here are the main causes of noise behind the steering column:
- The clearance on the bearings installed in the steering wheel hubs has increased. Solution: adjust the gap, and in case of significant wear of the bearings, replace them completely;
- The fastening nuts on the steering rod pins have become loose. It is these nuts that usually cause loud squeaking and grinding noises. Solution: tighten the nuts;
- The gap between the bushings and the pendulum arm of the steering system has increased. Solution: replacing the bushings (and sometimes you have to change the bushing brackets if they are very worn);
- The worm bearings in the gearbox are worn out. A grinding noise when turning wheels can also occur due to them. Solution: replace the bearings. And if the bearings are not worn out, it is necessary to adjust their clearances;
- loosening the fastening nuts on the swing arms. Solution: tighten the nuts after placing the car wheels straight.
Leakage of lubricant from the gearbox
A lubricant leak indicates a violation of the seal of the device.
Oil leaks are clearly visible on the steering gear housing
Here's how it happens:
- The seals on the bipod shaft or on the worm shaft are completely worn out. Solution: replace the seals (sets of these seals can be purchased at any spare parts store);
- The bolts holding the steering system housing cover have become loose. Solution: tighten the bolts, and they must be tightened crosswise. That is, first the right bolt is tightened, then the left, then the top bolt, then the bottom, etc. Only such a tightening pattern can guarantee the tightness of the crankcase cover;
- damage to the sealing gasket under the crankcase cover. If the above tightening pattern does not lead to anything, it means that the seal under the crankcase cover has worn out. Therefore, the cover will have to be removed and the sealing gasket replaced.
The steering wheel turns hard
If the driver feels that it has become very difficult to turn the steering wheel, this can happen for the following reasons:
- Incorrect alignment of the steering wheels. The solution is obvious: install the car on a stand and set the correct toe and camber angles;
- one or more parts of the steering system are deformed. Steering rods are usually deformed. And this happens due to external mechanical influences (flying stones, regular driving on uneven roads). Deformed rods will have to be removed and replaced with new ones;
- the gap between the worm and the roller in the steering gear has increased (or vice versa, decreased). Over time, any mechanical connection can become loose. And worm joints are no exception. To eliminate the problem, the roller gap is adjusted using a special bolt, then the gap size is checked using a feeler gauge. The resulting figure is checked against the figure specified in the operating instructions for the machine;
- The nut on the swing arm is too tight. The peculiarity of this nut is that over time it does not weaken, like other fasteners, but rather tightens. This occurs due to the specific operating conditions of the pendulum arm. The solution is obvious: the nut should be slightly loosened.
Change of oil
To carry out everything correctly and competently, you need to arm yourself with the following:
- wire brush;
- screwdriver;
- ring wrenches “8”, “12” and “13”;
- hex key to “12”;
- transmission oil;
- oil syringe or blowers with dispensers.
Note. Replacement work is carried out on a lift or inspection ditch. The replacement procedure is quite simple. After installing the car on a lift or inspection hole, first of all, you need to check the oil level in the gearbox.
Checking the oil level in the gearbox
To do this you need:
- open the hood of the VAZ and wipe the surface of the gearbox from dust and dirt, clean the filler and drain holes from adhering dirt using a metal brush;
