Purpose, malfunctions and repair of the VAZ 2107 steering gear

Greetings to all readers and guests of my blog!

Nothing interesting is happening with the car at the moment... so I decided to go back in time and remember what interesting things I did last winter... fortunately I have photographic material.

Well, I’ll start with a very useful modernization - the Steering Control of the VAZ 2107 (2105).

I think many owners of classics know that “fives and sevens” have a slightly different steering wheel, namely:

— A steering gear with a long shaft is used — A steering shaft with a cardan mechanism — Another form of steering column, and a plastic cover with it. Convenient location of the emergency gang.

Based on this, I have long noticed this convenient modification for myself, and I have been thinking about the benefits of it in my head:

1) No problems with the alignment of the shaft and gearbox.
More convenient installation and repair and disassembly.
Compared to the old one - easier rotation of the steering wheel (subjective) 2)
Cardan shaft - + for safety. The shaft folds in half during an accident, and does not cause as much damage to the driver as the “spear-shaped” one from 03/01/06.
3)
Modified column casing with a convenient location of the emergency lights. The “seven-five” column cover is convenient - the emergency light is always “under the right hand”, it is aesthetically pleasing - it covers almost the entire shaft up to the pedals, + covers the wiring and technical components of the steering wheel.
So, having “finished off” the old original steering wheel, and unable to bear the huge backlashes and knocks anymore, I decided to replace it with modernization. At the same time I’ll change the trapezoid and pendulum.

Here is a list of what I needed to buy (for me):

— Steering gear 2105-07 (with a long shaft) — Steering shaft 05-07 of two parts (upper and lower half) — Steering column (“binoculars” in popular parlance) — Two needle bearings on a rubber cage — Plastic casing 05-07 — Steering shaft seal (under the pedals)

— Steering linkage assembly — Steering pendulum (on bearings)

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.

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:

1. The driver begins to rotate the steering wheel, the wheel size of which ensures that this task can be performed quite simply;
2. By means of a composite shaft, a worm gear is activated, which reduces the speed;
3. The steering mechanism is lubricated with special oil (TAD 17) poured into the gearbox;
4. The worm gears rotate, which causes the double ridge roller to move;
5. This, in turn, causes the secondary shaft to rotate;
6. The tray mounted on the secondary shaft makes a turn and pulls the rod system behind it;
7. These components influence the levers that synchronously rotate the wheels to the required angle specified by the driver.

Steering gear housing parts

1 - crankcase; 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.

Details

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

Gearbox oil

To reduce friction of the internal elements of the steering column, GL-4, GL-5 transmission oil with a viscosity grade of SAE75W90, SAE80W90 or SAE85W90 is poured into the mechanism. In the old fashioned way, many car owners use TAD-17 oil for the unit in question. The filling volume of the gearbox on the VAZ 2107 is 0.215 liters.

Checking the oil level

To avoid premature failure of mechanism parts, it is necessary to periodically check the oil level and replace it. It is worth taking into account that the fluid from the gearbox, although slowly, leaks, and the leak occurs regardless of whether the column is new or old. The level check is performed as follows:

Use a 8 wrench to unscrew the filler plug.

How to change the oil in a gearbox

As for changing the oil in the steering device, this procedure should be carried out every year and a half. If the decision has been made to change the lubricant, you need to know how to perform the procedure. In addition to the new lubricant, you will need two syringes of the largest possible volume (purchased at the pharmacy) and a small piece of washer hose. The procedure is carried out in the following order:

Use a key to unscrew the filler plug, place a piece of tubing on the syringe, draw in the old oil and pour it into the prepared container.

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.

1. 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.
2. 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.
3. 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.

We will completely improve the steering!

Everyone prepares for the new year differently. I want to take part in a couple of competitions during the New Year holidays. If you are not afraid of cold garages and colds on your face, then my story is for you.

Whatever one may say, precise control on the track is a very important thing. And in my case, the play on the steering wheel is colossal. I got the car in pretty bad condition. Lately, all I've been doing is eliminating oil leaks from certain components. This time was no exception, and I took up the steering partly because the steering gear was flooding the snow-white asphalt with puddles of dirty oil every time I stopped.

If you do it, do it well. So I removed the steering gear completely from the car. Like all spare parts before this, after removal they look like a piece of oily shit. But in this pile of dirty pieces of iron, some will recognize the steering pendulum from left to right, connected through the middle link to the steering gearbox.

During the inspection, it turned out that I already had a pendulum arm installed on bearings, but it was smashed to pieces and it turns with great effort. And in the gearbox, oil presses from both seals in completely indecent volumes. Unfortunately, simply changing both seals was not at all easy for me. I finished off the gearbox myself and ended up having to buy the entire assembly new. On the left are old, but already washed pieces of iron, and on the right are new spare parts.

This seemed to me not enough and I wanted to install a steering gear bracket. Not many people know, but on domestic classics, the steering gear eventually begins to wrap the spar around itself))) It sounds crazy, but in the most advanced cases it even rips itself out of the spar. At the initial stages, there is a gap in control. This can easily be fixed with a steering gear bracket. In our country there are two large manufacturers of similar pieces of hardware, but neither of them works when purchased without modifications. Therefore, I put this revision aside for now.

neither this one fits

nor competitors' products

Now it's the turn of the wheels. Here we will switch to the newest type of bearings))) I mean that the obsolete cone bearing mechanism in the hub of a VAZ 2107 can be replaced through spacers with the hub (rear) of a VAZ 2108. This will no longer allow you to be smeared head over heels in grease and play on the wheels structurally will disappear. More details in the video, because... Otherwise I'll just overwhelm the whole story with a huge number of photos.

And for dessert my original Chinese RUDDER! This is a very necessary thing indeed. Many people think that such things are staged solely in order to stroke their pride and impress... I don’t know who. Well, for some people in general)) But a good steering wheel with reach and not a large radius is simply necessary on the race track. It is extremely inconvenient to intercept the huge steering wheel. If you take into account that this needs to be done quickly, then the civilian steering wheel simply disappears. I ordered mine from China and bought the spacer here and it is REALLY BAD. Because it is not injury-proof. Those. It doesn't fold when hit - it's a very dangerous thing. So I'll replace it as soon as possible. The steering wheel has a persistent smell of glue, but it performs its functions and I have not yet found any disadvantages, except for smelly hands.

In order not to be unfounded, I decided to test my improvements on the most winding track that can be found in Yekaterinburg. And I liked the result, although I again spent a lot of evenings in a cold garage. The race itself and a detailed story on video. And Andrey and I, who often remain behind the scenes, wish you a good holiday weekend! Maybe someone will even get out on the track during the holidays and give it a blast in their car (sober as glass). See you on the track!!!

Adjusting the Steering Gear VAZ 2101 - VAZ 2107

So, take a look at the photo of Rulevogo Reductor - a; - Do you see the nut (by the way, it is 19-size), and the pin with a slot - coming out through exactly that nut? The nut is a lock nut that locks the one we need and directly performs the adjustment - the stud.

Let's assume that the steering gearbox of your VAZ 2101-2107 is too tight. Then, you should take a wrench or a 19-point socket, loosen the nut (which we mentioned above), remove the locking gasket, and Unscrew the Pin with the Slot. This reduces the load on the steering mechanism of the column. Did you unscrew it? — try the steering wheel now.

Did you unscrew it too much and there was some play? Then you should screw the pin back in.

I think this is all clear. I would like to add that when adjusting the steering gear of a VAZ 2101 and other classics. The play, which did not seem to interfere with turning the wheels in place, and at low speeds, is actually felt at high speeds; - over 80 km per hour.

Therefore, you need to tighten the steering column just enough to just remove the play, or leave it minimal. This way, you won’t ruin your car’s steering mechanism, and you won’t fly off the road when turning.

• What else can cause your steering wheel to not turn?

So; — wheel width, wear of ball joints and steering rods; - this is probably too banal. But, for example, I was surprised when the steering wheel of my Kopeechka, after installing a new column (adjusted) and a new shaft, simply became very tight. The very next day, after a run of 80 - 100 km, it was no longer as light as before, but not as tight as on the previous day of installation. As they told me at the service station, it takes a little time for the new shaft to get used to the bushing, and then it will spin normally. Well, we’ll see, I hope it will be so. But if the situation does not change soon, then I will unsubscribe).

Personally, this is not clear to me; - how, despite the fact that the old bushing was already clearly free for the new shaft; turned out to be too tight for the new one? It’s strange, but time will tell.

One of the main devices of a car responsible for control is the gearbox.

In the VAZ 2107 car it is made in the form of a cardan. The driveshaft is the most reliable for the driver, since as a result of a frontal collision, it folds without causing harm.

Replacing the Steering Gearbox of a VAZ 2107 with Your Own Hands

replacement gearbox for VAZ 2104, VAZ 2105, VAZ 2107

The control transmission is still popularly called the control column, thanks to which the wheels of the car rotate; it consists of an integral part of the body and the shaft coming out of it, by the way, depending on the length and thickness of this shaft and depending on the size of the parts themselves ( for example, from the worm itself inside the gearbox housing), which are inside the gearbox housing, the steering wheel can rotate quite easily if all the parts have huge shapes (the longer they are in length, the easier it will be to turn the steering wheel), everything is fine, since the gearbox makes it easier for the wheel to turn and transmits all the torque to the wheels of the car, but it doesn't matter that the other part wears out over time and starts leaking mostly after wear, especially if you don't add oil to the gearbox, then over time it becomes very difficult to turn steering wheel, especially when driving at very high speeds, this is especially noticeable. This is possible because the gearbox is in need of repair (if it can still be repaired) or because it can be quickly replaced.

gearbox manager You will need tools on your machine, namely a basic set of wrenches, as well as various other types of wrenches, in addition, it is recommended to use a ring socket and a screwdriver, since it is not always convenient to turn the nuts with a wrench without taking into account (this does not apply to tools), you will also need to take a helper with you, as you will have to do this operation together, as it is more convenient!

Where is the steering gear?

It is located in the engine compartment and at the bottom of the car, so it is not very convenient to remove from above, so for this job you will need a second person to pick up the transmission itself once you have removed all the mounting nuts.

If you want to see the gearbox itself, in other words, where it is located, then open the hood of the car and look where the body (not the engine) is located on the driver's side, you have a gearbox that was shown with a red arrow in the photo just below for clarity :

When should I change my steering?

Many people advise going to a car dealership, getting a new gearbox and replacing it with a new one, although it can be fixed like any other part (Vita doesn't have all the money to buy a new unit), but it works. It's up to you to decide here, but we will list the main ones malfunctions that occur when the steering gear , firstly, oil can seep into it (be it the rust and corrosion that left it, or the oil seal that it sent requiring its own replacement), not counting it, the steering wheel through a worn The transmission control system may also rotate a lot (There are many other components in the steering that are responsible for steering, because if your steering wheel starts to rotate a lot, do not throw all the obstacles at once to the steering gear , as this may be due to the pendulum arm , as well as other details).

In addition to all the above problems, due to wear and tear on the transmission, the steering wheel may simply get stuck (won't turn) and may turn, but the wheels will not turn, as this transmission plays a very important role. role in cars, and if you have seen any of these problems in it, we advise you to replace it with a new one as soon as possible, or if you do not have the opportunity, just repair it, and after proper repair, it will work like before! (See the article “Repairing the steering gearbox on a VAZ” on how to block the gearbox)

How to replace the steering gearbox on a VAZ 2104, VAZ 2105, VAZ 2107?

1) First you will need to put the car on the inspection hole to work, or if you are not afraid, you can connect the front of it and put not very thick plates under the front wheels, and then lower the car on them, in this regard it will become higher, but it won't work very well because, as they say here, it's up to you to decide what to choose.

Malfunction of the steering gearbox.

The VAZ 2107 gearbox does not require excessive intervention. The main condition for normal operation is the presence of lubrication.

Creaks or extraneous sounds in the structure are common damage. Since in this model the steering wheel is attached to the shaft using splines tightened with a nut, if the fastening is loosened, the splines will be most subject to wear, and the steering wheel will dangle. Squeaks may be heard from the driveshaft crosspieces, which appear as a result of wear of the mechanism parts or lack of lubrication.

Also, damage to the steering wheel play is common.

The driveshaft may come off and, as a result, a gap appears. To adjust the steering column, a bolt with a lock nut is provided. The nut is pulled back and the bolt is screwed in until the play returns to normal. This nut is then tightened and secured in position. After this process, the steering wheel will turn much tighter, but the play will be reduced.

Before you start checking the steering mechanism malfunction, subject to the identified symptoms, you need to adjust the gearing. If the adjustment is unsuccessful (for example, the steering wheel rotates tightly, but the play has not disappeared), then you should disassemble the gearbox to find faulty or non-functional parts of the mechanism.

Step-by-step replacement of the steering wheel

You can remove the steering wheel in a VAZ-2107 yourself, but in order for the process to be completed correctly, you need to do it step by step:

1. The battery lock must be done first to prevent short circuit. To do this, it will be enough to disconnect the negative terminal from the battery.
2. Using a small screwdriver, you need to pry off the Lada logo, which adorns the middle of the steering wheel. This logo is not only a decoration of the steering wheel, but also an original plug that covers the fastening element.
3. After the plug is removed, you can see a 24-size nut inside, which must be unscrewed. Before unscrewing, you need to set the steering wheel to a position in which the wheels of the car will “look” directly from the body.
4. A size 24 socket must be inserted into the extension so that it is convenient to put the tool on the fixing nut. Next, you need to insert such a device into the so-called knob and try to turn the latch with a sharp counterclockwise movement. In this case, you should hold the steering wheel with your knees so that the structure does not turn when unscrewing the lock. If the nut does not come off the first time, you need to repeat the whole process again, but experts do not recommend completely unscrewing the lock. This is explained by the fact that the steering wheel is quite firmly attached to the shaft, and if it is removed with a sharp jerk, the structure can hit a person hard in the chest.
5. Once you feel that the fastener has become loose, you need to start swinging the steering wheel in different directions. You can completely remove the steering wheel from the shaft after you hear a peculiar click. This will indicate that the steering wheel is starting to hit the nut, so the clamp can be completely unscrewed without fear.

Such simple manipulations and a minimum of tools will help VAZ-2107 owners remove the steering wheel without much effort for further replacement of the structure or troubleshooting any problems.

Step-by-step adjustment of the worm gear.

In order to independently adjust the steering gear of a VAZ 2107 car, you need a flat screwdriver, a 19mm wrench, the help of another person and follow the step-by-step work:

• In order for the steering mechanism to be adjusted efficiently, the car must be placed on a flat surface, and the wheels must be in a straight position.
• Next, open the hood and clean the gearbox from dirt. Then you need to find the adjusting screw located in the center of the crankcase cover. This screw is covered mostly by a plastic plug. Before removing it, the plug must be pryed off with a flat screwdriver.
• Then you need to use a 19mm wrench to loosen the nut located on the adjusting screw.
• After loosening the nut, the assistant intensively turns the steering wheel in both directions. At this moment, together with it, it is necessary to start rotating the adjusting screw so that the necessary clearance appears in the meshing of the gears. Free play should be minimized and steering wheel rotation should become much easier.
• After the gap is adjusted, it is necessary to tighten the lock nut tightly, while holding the screw with a screwdriver.

Procedure

The procedure is performed in two stages. The first is the removal of the VAZ 2107 steering gear:

1. The machine is installed on a pit or a lift.
2. 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.

3. Now the intermediate shaft fasteners, which connect the mechanism to the steering wheel, are dismantled.

4. 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.

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 key No. 19:

• 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.

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.

Checking the steering gear.

After adjusting the steering gear of a VAZ 2107 car, axial displacement of the steering wheel is possible. It can be detected if the front wheels are placed in a straight position and at this moment you pull the steering wheel up, in which case the shaft will move.

Increased play in the VAZ 2107 steering wheel is a fairly common problem, characteristic of the entire “classic” family. In most cases, you can fix the problem yourself without resorting to complex, expensive repairs. It is only important to correctly diagnose and localize the causes of play in the steering mechanism.

Checking the steering play of the VAZ 2107

Large play in the VAZ 2107 steering wheel is a vague concept. Meanwhile, the permissible steering play has established standards. For “classics” it is 5 degrees. To check the backlash, a special device is used at the service station - a backlash meter. At home you can do without it. To do this you will need a ruler, chalk (or wire) and the help of a partner. Checking the amount of play is carried out as follows:

• place the machine on a level surface;
• check the tire pressure and inflate them if necessary;
• align the steering wheel so that the wheels are directed parallel to the axis of the car;

Important: if the wheels are level, but the wheel spoke is skewed, then there may be a violation of the wheel alignment angles, and the presence of defects in the suspension and steering. The steering and suspension should be adjusted or repaired.

• place the ruler so that it rests on the dashboard, touches the top of the headlight switch and, with the other end, touches the wheel rim;
• smoothly rotate the steering wheel while your partner monitors the position of the front wheels;
• as soon as the wheels begin to shift, stop turning the steering wheel;
• make a chalk mark on the steering wheel opposite the ruler (or wrap the steering wheel with wire);
• smoothly rotate the steering wheel in the other direction until your partner notices that the wheels have begun to turn;
• make another mark on the steering wheel with chalk or wrap a second piece of wire around it;
• measure the distance between the marks on the wheel rim.

A play of 5 degrees corresponds to a displacement of 17 mm with a steering wheel diameter of 40 centimeters.

Causes of steering play in VAZ 2107

If you notice unacceptable play in the VAZ 2107 steering wheel, the reasons may be as follows:

• The central nut securing the steering wheel to the axle is not tightened;
• the nut securing the steering column to the gearbox is loosened;
• The worm gear of the steering mechanism is not adjusted;
• the steering pendulum bushings are worn out;
• The tie rods are damaged or their ends are worn.

All of these problems require immediate intervention. Otherwise, the steering mechanism may fail and the car will lose control.

Replacing the steering column, instructions.

Replacing the steering column of a VAZ 2107 is a fairly simple process, which cannot be said about the preparatory stage, which is carried out as follows:

• First the battery is disconnected;
• then the steering wheel and steering shaft casing are removed;
• then the ignition switch and steering column control system are dismantled, the steering bracket bolts are removed;
• then the coupling bolt connecting the spline joint to the steering mechanism is unscrewed;
• at the last stage, the lower shaft seal is unscrewed and removed;
• Install a new one in place of the old steering column, observing the reverse order of the above steps.

How to remove steering play on a VAZ 2107

You should begin work by checking the tightness of the threaded connections of the steering mechanism and the condition of the steering rods (tips). Bent rods or worn tie rod joints must be replaced. To do this, you will have to use a puller and a 22mm wrench. You should not try to align the rods or repair the ends. For safety reasons, these parts should always be replaced with new ones. Next, you should check the condition of the pendulum and the adjustment of the worm gear. Worn pendulum bushings must be replaced with new ones. To do this, you need to unscrew the steering rods from it (use a 22mm wrench and a puller) and remove the pendulum from the car by unscrewing the mounting bolts. Clamp the pendulum in a vice, remove the cotter pin and unscrew the adjusting nut. Once the nut is unscrewed, you can disassemble the pendulum and replace the worn bushings with new ones. When assembling the pendulum, it is necessary to tighten the adjusting nut so that its bipod rotates with a force of 1-2 kilograms. If all parts are replaced or in good condition, and the threaded connections are tightened, the VAZ 2107 steering play is adjusted by adjusting the steering gearbox. To do this, you will need a 19 mm wrench and a powerful slotted screwdriver. The adjustment is carried out as follows:

Further repairs will not be a problem.

You only need to follow a few rules:

• the worm pair is changed simultaneously, as a set;
• after assembly/disassembly, adjustments need to be made;
• Do not use old oil, but replace it with new lubricant.

After the repair is completed, the gearbox is assembled and mounted in the reverse order.

The steering gearbox is a rather old mechanical device that is now used mainly on cars of the classic LADA family. Today you will learn what a steering gearbox is - repair, replacement, adjustment with your own hands.

The steering gearbox is a small mechanism designed to transfer rotational motion to translational motion. This means that the gearbox converts the rotation of the steering wheel into a force that shifts it in the right directions, causing the wheels to turn and change the direction of movement of the car.

The gear used in the gearbox is a reduction gear and consists of two elements - a worm and a gear. In addition, the mechanism has a special lever that moves the steering rods in the right directions.

The steering gearbox of the VAZ 2107 is sealed and, which significantly increases its service life and simplifies turning the steering wheel, reducing the effort exerted by the driver.

↑ What spare parts will be needed?

In case of replacing the entire assembly, the only thing that needs to be purchased is the original part (part number 21050-3400010-00). If this is not possible, you can buy units with other designations, but it is still better to use original components.

↑ Tools and accessories for repairing the steering gear

• set of wrenches;
• beard;
• screwdriver;
• hammer;
• vice;
• mandrel (you can take a piece of pipe of the appropriate size);
• rags.

The repair sequence for the VAZ 2107 steering gear can be divided into two main stages.

Video - Steering gear repair

In most cases, this unit is not repairable, since it is relatively inexpensive and consists of only two main parts. However, the manufacturer left the option for car technicians to purchase a repair kit.

Before repairing the steering gear, let's determine the malfunctions.

• Firstly, it can be repaired if the steering wheel rotates but the wheels do not. This means that there are defects on the threaded part of its shafts that prevent the two interacting parts from touching.
• The second type of fault is oil seals. If they have reached critical wear, then the oil from the gearbox will certainly leak, which already leads to its accelerated wear. If there are other mechanical damages, the gearbox must be replaced.

First, remove the faulty unit from the car. After this, press the bipod off its shaft using two hammers. Drain the oil from the gearbox through any technological hole. Now unscrew the four bolts that secure the cover and remove it. To access the worm shaft, you need to unscrew a similar cover on the other side of the mechanism. Pull out the remaining parts and replace the faulty ones. These may include oil seals and damaged shafts. After this, reassemble the gearbox in the reverse order. Don't forget to add oil!

How to change the steering gear on a VAZ 2107

If there is more serious damage, the steering gear must only be replaced. To do this, you need to purchase a new VAZ 2107 gearbox and immediately fill it with transmission oil. Now you need to remove the faulty gearbox from the car.

• Disconnect the tie rod ends from the tie rods. To do this, first unscrew them, and then unscrew the fastening nuts using a 22mm wrench. To pull them out, you need to use a special puller, which is available in any auto parts store.
• Go inside the car and loosen the clamp that secures the steering shaft to the steering gear. Pull the shaft out of engagement with the gearbox.
• All that remains is to unscrew the three bolts that secure the mechanism to the engine compartment of the car.
• Install the new gearbox in reverse order. Before you start operating the car, do not forget to adjust it.

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;

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.

Adjusting the VAZ gearbox

Adjustment of the steering gear is carried out to get rid of play in the steering wheel, as well as all kinds of discrepancies when it rotates with the position of the wheels. The car wheels must first be aligned.

To adjust the steering gear, you need to unscrew the lock nut on its cover from above and loosen the special adjusting screw. Ask your partner to sit behind the wheel and rotate the steering wheel in different directions with energetic, but not wide movements, while you gradually tighten the adjusting screw. As soon as the steering wheel begins to rotate tightly and the wheels move with the slightest movement, the locknut is tightened.

This completes the adjustment of the steering gear. As you can see, this procedure is not long at all and can be performed with just a 19-mm wrench and a regular flat-head screwdriver.
