Every car owner knows what a spar is - it is a longitudinal beam on a frame on which the body rests, springs and a number of parts are attached. It often breaks at the point where it comes into contact with the stabilizer, which makes the steering wheel stable, even despite the presence of amplifiers. Cracks appear there, which can be noticed when checking the chassis. And the deformation of the body geometry is associated with the active operation of the car in Russian conditions. If the owner of the car has not yet changed the VAZ 2110 spar, but is faced with its breakdown, the part is replaced with his own hands.

Please note that in a neglected state, the spar (VAZ 2110) is not repaired, but replaced.

The main thing is to pay attention to the breakdown in time and eliminate it by welding in the internal part of the product.


Despite the amplifiers available in these places, the spars fail and require either repair or replacement

The key causes of failure are:

  • poor quality of road surface;
  • driving over potholes at high speeds;
  • weak fastenings. If the rigidity in the steering mechanism decreases, cracks appear near the bolts. Then there is play on the body, and then the wheels get toe defects.

Another problem: how to pull out the spar with your own hands? The procedure is required when it is bent to the side during an accident and involves a bench hood.

If the car owner has never encountered such a factor as replacing the front side member of a VAZ 2110, you should either contact specialists or carefully study the method of removing it and installing a new one. Most often, a breakdown occurs at the attachment point of the stabilizer, which is responsible for lateral stability, and the place where the steering wheel is attached. Despite the amplifiers available in these places, the spars fail and require either repair or replacement. Replacing the front side member on a VAZ 2110 can be easily done with your own hands.

Which gear oil composition to choose?

On the Russian market, transmission oils are divided into three types according to their chemical composition:

  • synthetic;
  • semi-synthetic;
  • mineral.

From the factory, as we have already said, Magnum 300 from TNK is poured. In terms of its composition, it belongs to. But less than 5% of Lada Kalina owners use this type.

The most preferred type of lubricant is semi-synthetic. This type is chosen by 50% of drivers, and we recommend it. And 45% of car owners buy fully synthetic fluids. What kind of oil you put into your manual transmission depends entirely on you.

Spars are an important component of the body

Note. In a neglected state, the part cannot be repaired and requires replacement. If damage is noticed in time, it can be repaired by welding into the inside of the spar.

Replacing the front side members of a VAZ 2110

When actively using the car or traveling on roads with harsh driving conditions, cracks appear in the side members, which are detected only during diagnostics of the chassis (see Repairing the chassis on your own). If you do not notice them for a long time or do not take the necessary actions, the part is destroyed and, subsequently, cannot be repaired. The causes of failure are usually:

Front spar VAZ 2110

Due to the weakening of the rigidity of the steering mechanism fastening, a crack appears near the bottom bolt, followed by play in the body and, as a result, the wheels of the car become misaligned.

Replacing the front spar

To fully replace the side members, the following tools and spare parts are required. Without them, you can get yourself into trouble in the form of the inability to dismantle the old part and install a new one:

Note. Problems may arise when unscrewing the bolts. To overcome them, do not neglect any of the recommended tools.

You can purchase the spar and mudguard as a set or individually for each part. When trying to save money, they often decide to purchase separately and cook it themselves. This results in wasted time during installation and welding.

Note. The package of these elements separately does not include all the necessary parts and they will have to be purchased additionally.

To clearly understand further actions, you need to examine the engine shield. This is that part of the car, or rather its body, that separates the engine compartment from the interior. It is to the engine shield that the engine splash guard must be attached. If it is in a condition that does not evoke positive emotions, it will not be possible to weld the mudguard, which will significantly affect the rigidity of the body.

Small corrosions that do not have a significant effect on the condition of the engine shield are not scary. To bring it into proper condition, you can use patches. They are made of metal, which you will also have on hand. In order to unscrew the upper ball joint, which simply needs to be dismantled, it is advisable to purchase fasteners for this ball joint. If the bolts are in poor condition, a lot of time will be lost. Tools that should be:

Note. It is important to maintain consistency throughout the entire work process.

The process of replacing the spar begins with removing the door (see Repairing VAZ doors: how to do it correctly) using an impact screwdriver and removing it until the process is completed. Next you need:

Note. To protect the drive boot, a small stand is installed under the front wheel beam. This way you can prevent it from falling at the moment when the upper ball is released from the lever. This prevents the brake disc from touching and damaging the brake flap.

Note. You will have to try hard to get the spar into place without moving the body and bridge.

The front spar of the VAZ 2110 burst

Unfortunately, it is not possible to bring in a new spar in its pure form. The reason is the welded front panel into which it must be inserted. To eliminate this discrepancy, you need to saw off the tip of the spar. Having installed the spar in place, the tip is inserted into the front panel, and then welded with a continuous seam, which restores the integrity of the part. So:

Note. If defects in the engine shield are detected, they are eliminated during the process.

For those who have a desire to repair and transform a car with their own hands, the step-by-step instructions given above will be an excellent assistant in their work. The cost of parts is not high, and you can save a lot on repairs without resorting to expensive services. Photos will help you better understand the location of each detail, and the detailed video, which is located here, will be a clear example for anyone who has decided to act.

The procedure for carrying out repair work

All work is conventionally divided into 3 stages: preparation of the bottom, replacement of the entire element or re-welding of individual parts, reassembly of the dismantled parts.

Tools and materials for work

Work is carried out after changing into dry clothes suitable for welding work. Before starting, prepare tools (grinder, welding machine, drill) and consumables. You will need new soundproofing sheets, as well as:

  • mastic;
  • primer;
  • sandpaper;
  • protective enamel.

After disassembly, it will become clear whether the repair will include additional metal parts, or whether the entire bottom of the VAZ 2112 will need to be welded.

Safety precautions

Since the work involves welding, fire safety of the work must be ensured. To carry out proper repairs, you should turn off the power to the car and drain all the fuel from the tank. For convenience, the doors in the cabin are dismantled, having previously de-energized the windows. In order to preserve the geometry of the body, after removing the doors, the openings are strengthened by installing spacer elements.

Diagnostics and repair

The damaged element is subjected to a drawing process on an appropriate measuring stand. The quality of work is checked at control points, according to the recommendations of the manufacturer. It is interesting that the necessary data, diagrams, devices, as well as qualified and specialists are not available in every branded service. Of course, restoring a car with your own hands in a garage is generally a futile endeavor. At best, it will only be possible to return the superficial, original appearance, but not to return the previous factory geometry.

Before undertaking repairs to the spar, it is recommended to first perform a wheel alignment. This simple procedure, which should definitely be carried out when purchasing a car, will show whether restoration work is necessary and how labor-intensive it will be. In most cases, deviations from symmetry, the visible absence of smooth lines along the body, unstable gaps in the doors, hood, and trunk indirectly indicate, at a minimum, that the car was disassembled and, probably, repaired.

The spar is drawn out on a robotic slipway. A bracket is welded to the defective unit, using which the hood is pulled using a hook, chains, and a winch. In a garage workshop, instead of a lifting mechanism, you can get by with a cable and a fixed support, for example, wood. The tinsmith sits behind the wheel and, by smoothly slipping, tries to pull out the part. If the damage is critical, only replacing the spar will help. It is worth considering that with a new part, probably, due to existing damage, you will have to change the subframe, suspension elements, engine mounts, etc.

Tools and materials

Replacing the spar (VAZ 2110) requires the following consumables:

If damage is noticed in time, it can be repaired by welding with penetration into the inner part of the spar

Replacing the front side member of a VAZ 2110 requires an examination of the engine shield - the part of the car body that separates the engine compartment from the car interior. The mudguard is attached there.

If there is corrosion on the surface, treat it with anti-corrosion agent, sand it and apply a patch.

To unscrew the ball joint, special fasteners are required. Of the tools you should have:

There is no need to draw, we need to repair


To approach and crawl up to the “dead” spar, you need to remove all obstacles from the car, namely, body parts located on the way to it. Remove all vehicle wiring and any electrical devices from the area being repaired. Did you find the spar? Now try to stretch it out, at the same time and if possible giving it its original shape. Naturally, you won’t achieve anything perfect yet. But. Secure the car with chains on the stand and use a grinder to cut off the parts of the spar that cannot be restored. After pulling and cutting, check how the car doors close. Then, using a gas torch, remove the old layer of sealant and primer by simply heating it. The geometric control points of the spar must be checked according to the repair table, and the notches of these points can be made with ordinary colored tape. Then pull the spar to the marks that coincide with those indicated in the table. To smooth out any rough spots, use a sander, and be sure to check the exact parallelism between the side members and the wheel arches. Use a straightening hammer to fix any damaged parts of the wheel arches. Then apply a new coat of sealant and primer and get ready to paint. After painting, you can reassemble the previously removed body parts in the reverse order, naturally, after the paint has dried.

Bodies and what they are like

ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"

As you know, the body on the “ten” is load-bearing and repeats the basic design of any modern passenger car. Today it is customary to talk about several types of bodywork. The frame and supporting body are considered the main ones.

The difference between frame and load-bearing

All the main components of the car are located on the frame; it serves as a support and is itself fixed to the wheels of the car by means of suspensions. If you pay attention to trucks, then the frame can be seen with the naked eye, and thus you can draw appropriate conclusions about its structure. In “passenger cars” there is no frame, or it would be more accurate to say that on some passenger cars the frame-body assortment forms a single whole, called the body.

Frameless bodies, which include the metal frame of the VAZ 2110, are made in such a way as to withstand the mass of numerous heavy components. For this purpose, the body floor is well reinforced, and most of the overall parts are made of materials with a lightweight base.

On frameless bodies, the role of the frame is performed by the spars. They can be said to be responsible for the massiveness of the entire body structure. From time to time, these components are subjected to unplanned and shock loads that change very quickly in different directions. This operating scenario cannot have a positive effect, and over time, the welding points break, the bolts become loose, and the solidity of the entire body structure weakens.

The car body also feels the load from a running engine. It vibrates strongly, although the engine itself and the cylinders are designed to absorb some of the vibrations. To minimize the effects of vibrations on the body, manufacturers use special cushions or dampers, as well as washers made of dense rubber.

Note. The effect of these pads can be clearly determined by monitoring the operating unit with the hood open. The engine “growls” and shakes, but the body doesn’t care.

The most important task of a frameless car body is to transport luggage and passengers. At the same time, the machine must also provide major protection. The number of people transported and the weight of the permissible load are determined by the designers responsible for the layout and other parameters of the body.

If you imagine the frame of a “car” in the form of its components, then its main parts are three main zones, implying the trunk, the passenger compartment and the front. The finished look of the solidity of the frame is given by its hinged parts or “plumage”, which includes various panels.

Body types of the “tenth” family

The difference in body types, again, is associated with what one or another model is intended for. The car may be intended for off-road travel, and then it will be designed as a crossover or a full-fledged all-terrain vehicle, or it may be intended only for city driving.

Note. The body of the VAZ 2110 is a typical sedan. Models associated with the “ten” already have other body types: 2111 – station wagon, 2112 – 5-door hatchback, 21123 – coupe or 3-door hatchback.

It will be useful to know that over the entire production period of the 2110 model, VAZ creates many variations of this sedan. In particular, the Consul limousine, with an even longer wheelbase, deserves attention.

The design of the sedan began immediately after the VAZ 2108 became obsolete, when the plant decided to replace the project. But the release of the “ten” was not yet imminent. The fact is that the designers made many revolutionary improvements that significantly increased the cost of the project. Due to the economic crisis that reigned in the country at that time, the project was moved forward several years, and only in 1995 mass production of the “ten” began.

The sedan is the classic and most popular body style of modern cars. The interior includes 2 rows of seats and usually accommodates 4-5 people including the driver. The luggage compartment in sedans is properly separated from the interior.

For many, to this day, the question of the merits of the VAZ 2110 car is somewhat controversial. It is clear that it cannot compare with foreign cars, but the presence of “ten” running on the roads of our country speaks volumes.

Dimensions and how much it weighs

The body length of the “ten” sedan is 4265 mm, which is only slightly less than the “universal” dimensions. This length looks the most organic not only among the models of the “tenth” family, but also in VAZ as a whole.

We also note that the length of the “ten” is 6 cm longer than the length of the only “Samarov” sedan - VAZ 21099. The same goes for other parameters:

But both gauges are the same for “99” and “tens”. In addition, both models have similar gearboxes and engines. But still, in general, the technical characteristics of the “tens” and “99” are different. The “Ten” is able to achieve better speed and demonstrate enviable maneuverability on the road compared to the “99”, precisely due to the body design, made with modernizations and significant improvements. In particular, these are smooth body lines and completely modernized control systems.

To replace the spar you will need:

Spar repair options

The spar is made of an extremely strong steel alloy, which is almost impossible to deform; its strength is incredibly high. However, as everyone knows from junior school physics classes: force is speed multiplied by mass. For example, a light car collided with a KAMAZ, as a result the passenger car was completely deformed, and the body of the KAMAZ was only partially, but still deformed. It should be objectively understood that even a very strong material can be deformed, it all depends on the force that acts on it. The point of direction of the force, as well as the degree of its application, determine the nature of the damage. Any significant traffic accident almost always damages the spar, sometimes completely. In this case, you have to completely replace it.

Note. If there is no confidence in the objectivity of the assessment of the exact nature and extent of damage to the car, then the most rational option would be to seek help from a car maintenance service.

The spar in the VAZ 2110 burst

If the spar is only partially damaged, for example, in the form of a crack, then you can try to eliminate this defect by welding. However, it is also necessary to objectively understand that not every defect can be eliminated by using welding. For example, if the attachment of the spar to the body of the vase is damaged, then most likely welding will be ineffective. The only way to eliminate the defect is to make a complete replacement.

What is better to eliminate the existing spar defect or completely replace it?

Of course, the best option would be to weld a new spar instead of the old one, and also pre-strengthen the body. However, it all depends on the repair budget; the more financial resources are invested, the more effective the repair will be. Each motorist has different financial capabilities, so this nuance must be taken into account objectively. Therefore, the option of repairing the spar cannot be immediately discarded.

Note. If a motorist is not sure that he is able to do everything on his own, then it is better not to take risks and resort to the services of a car service. Observe the work of the car service employees and the next time replace the spar yourself.

The right side member of a VAZ 2110 burst

If there is a need to use welding, then it is best to use a semi-automatic machine with carbon dioxide. Also, when replacing the spar, it may become deformed, so be sure to first install spacers under the side members. Additionally, it is imperative to take into account the condition of the case, since sometimes its integrity is under very significant doubt.

Note. To reliably repair the spar, you need to make sure that the body itself does not have any defects, otherwise you will have to spend even more money on repeated repairs.

Also, do not forget about the well-known axiom that with each welding, the strength of the metal decreases, and this must always be taken into account without fail. If you do not pay attention to this technical nuance in time, an unpleasant cascade of negative consequences may occur:

The cost of performing body welding work in technical maintenance services is on average 4,500 rubles. Additionally, you will need to purchase a certain set of parts. However, there is a very real opportunity to do everything yourself, the main thing is to have a little knowledge about the structure of the body and a little experience in using welding. A crack after an accident can be welded, but the main thing is that the metal is strong enough.

Main types

Depending on the design features of the car, the following types of their location can be classified:

Trucks are characterized by a parallel type of arrangement of side members, which are in a horizontal position. Other types of arrangement are typical for cars and SUVs. The inclined type provides maximum turning radius of the wheels. Thanks to the vertically curved side members, a relatively lower floor height in the vehicle interior is ensured. Horizontally curved elements also affect the floor level, but in addition to this, passive safety is further increased in the event of an emergency with a side collision.

The cross members are responsible for the level of rigidity of the main parts of the car. They are located between the side members. There are three main types of crossbars:

Mostly metal materials are used for manufacturing. In large trucks, the side members and cross members are connected by riveting, and in passenger cars, these two components are simply welded. At the same time, special brackets are used to firmly connect the frame, body, main parts of the transmission and engine. They, in turn, come in many sizes and also have a high level of strength.

How to extend the life of the bottom

The body on all VAZ models is not a high-strength unit. To maximize the life of the main part of the car, it is recommended to systematically carry out preventive maintenance. It is impossible to completely eliminate the aging process of metal, but every driver can increase the service life of a new underbody.

  1. Prevent water from entering the cabin through depressurized moldings on the windshield and side doors.
  2. Systematically remove the rubber mats under the driver's seat and check the floor for dryness. Systematically clean drains in thresholds and doors. Particular attention is paid to the area under the battery: under the influence of the electrolyte, the drainage holes on the platform become coked.
  3. If the first rust is found on the bottom of the interior, clean it, fill it with epoxy resin, and treat it with an anti-corrosive agent with the effect of preserving corrosion areas.
  4. Clean chips and renew the paintwork on the sills immediately after detection: the sills and fenders begin to rot first.
  5. It is necessary to lift the car with a jack only with the doors closed.

Changing parameters

The spar, like other parts of the car, is subject to heavy loads and as a result, breakdowns or wear are possible. Since this is an important part of the vehicle, it becomes clear that in the event of a breakdown, literally everything stops working as intended.

For example, if the wing of a car is torn off, it continues to move, but if a spar breaks, it will no longer be able to drive. Then increased wear of the rubber occurs, the body begins to break, and the car itself is difficult to drive.

Functions performed by the structure

We have already found out where the spar is and even know what it is. But what it is needed for is not yet entirely clear. The spar is the most durable part of any car. Such a margin of safety is necessary to withstand the load exerted by the body, engine, luggage and driver with passengers.

This part also serves as a shock absorber for the front part of the body, absorbing impacts and preventing deformation. The body cannot be made very rigid and durable, since it will not be able to absorb the impact energy and most of it will be transferred to the passengers. This situation is unacceptable, because the body on the passenger side is minimally deformable and has the ability to absorb impact energy.

It is the side members that bear the greatest impact force. In this situation, they are often subject to deformation. But passenger safety increases significantly. Therefore, the sacrifice of the spar turns out to be justified.

Also, this part is subject to loads carried by surrounding working units, parts and mechanisms. Even the force from the wheelbase is absorbed by these robust structures.

Spars are an important component of the body

Note. In a neglected state, the part cannot be repaired and requires replacement. If damage is noticed in time, it can be repaired by welding into the inside of the spar.

Replacing the front side members of a VAZ 2110

When actively using the car or traveling on roads with harsh driving conditions, cracks appear in the side members, which are detected only during diagnostics of the chassis (see Repairing the chassis on your own). If you do not notice them for a long time or do not take the necessary actions, the part is destroyed and, subsequently, cannot be repaired. The causes of failure are usually:

Front spar VAZ 2110

Due to the weakening of the rigidity of the steering mechanism fastening, a crack appears near the bottom bolt, followed by play in the body and, as a result, the wheels of the car become misaligned.

Equipment and tools

Replacing rear side members on a VAZ 2110
Repair work to replace the side members must be carried out in an equipped and spacious garage. It is necessary to prepare equipment and tools:

Before starting repairs, you must remove the battery and drain all remaining gasoline from the gas tank. If possible, cover the gas tank with fireproof material. To prevent spontaneous combustion from remaining gasoline vapors in the gas tank. Since the repair will be carried out using a power tool that produces a spark.

How to choose a part: average prices

To weld the bottom of a car at a car service center, the minimum price is 25,000 rubles. This applies to minor floor defects in all customer materials. A complete overhaul and update can cost up to half the cost of a car. Considering that the price of a VAZ is minimal, such repairs are not profitable for most drivers.

Many people prefer to carry out repairs and replacements on their own, buying a solid bottom. The repair kit is produced by AvtoVAZ, the element is suitable for models 2110, 2111, 2112, 2170, 2171, 2172. The cost does not exceed 4,000 rubles. Cold-rolled steel 0.8 mm thick is used in production.

There are options on the market to buy bottom elements: panels, amplifiers, connectors and cross members. The cost of each element is from 900 rubles. Parts of the bottom are chosen instead of metal patches if local repairs are necessary without welding out the entire bottom.

Methods for replacing the spar

To replace the spar with your own hands, you must first align it and only then remove it. This is done by cutting. Incisions are made only along clearly defined lines. After this, a new one is installed in place of the old spar. For this purpose, special spot welding is used.

Partial replacement

If there is no need for a complete replacement, then it is quite possible to do it partially. This refers to the renewal and improvement of weakened areas. Only those sections of the side members that do not bear the entire load can be replaced. Most often, through partial replacement with your own hands, the spars are given shock-absorbing properties, and this is done as follows:

Do-it-yourself partial replacement has its positive sides. No coupling or specific type of welding is required. This part is installed very easily, and after all the work is done, it is adjusted to the required dimensions and installed back.

Complete replacement of the rear spar

If the spar is severely deformed or does not fulfill its main shock-absorbing tasks and does not fully provide the strength of the body, then its complete replacement will be required. To make the operation easier, the machine is driven onto an overpass or inspection pit. In cases where this is not possible, a regular jack will come to the rescue.

You should start by dismantling the parts attached to the spar, after which pulling is carried out. It is clear that it will not be possible to give it its original shape, but it is worth trying to get closer to this. Afterwards the protective coating is removed, and only then the spar itself is removed, that is, cut off from the fastenings.

If the spar has been successfully removed, it is time to prepare a grinder for further work, on which a special type of stone is mounted. Using this device, all welding residues are removed, and areas where corrosion processes have begun are also removed.

Upon completion of these works, the wheel arch is prepared, which is connected to it. Installation of the spar is carried out in the reverse order and is secured using welding. After installation, a thorough check. To do this, use the chiseled method.

Using a grinder, you need to refine all the places where the welding joint was made. To do this, the welding is removed using a grinder, and then these places are covered with a special sealant.

The process of replacing the front spar is carried out using a similar method.

What happens to the side members after an impact?

With a minor impact, the bumper reinforcement and front panel are deformed. The MFC LFA body shop specialists recommend replacing both damaged elements. After all, there is often, although minimal, displacement of the side members, both in the horizontal and vertical planes, and repair is impractical. And the stronger the impact, the greater the likelihood of wrinkles forming on the side members. In rare cases, the metal on them even breaks. Even a minimally misaligned side member can seriously affect the vehicle's handling and safety.

Restoration of spars


The front quarter of the Honda Fit spar, in the event of a minor impact, the craftsmen measure all the necessary distances between the power elements of the body using special equipment at control points.
Thanks to its huge database, MFC LFA has dimensions for repairing side members for almost all car models. If a deviation of at least a millimeter is determined, the car is installed on a slipway. It allows you to return the displaced power elements of the body to the places provided by the factory.

If folds form, the car is placed on a slipway for several days to return the required plane to the surface of the side members. Thanks to micron-stretching technologies for metal, the side member will not lose its rigidity.

After the work described above, sometimes tears occur at the folds. They need to be strengthened by welding.

If the spar is deformed by 25% or more, its partial or complete replacement is necessary. The front parts of the elements are sold at disassembly sites. The damaged piece is cut off and a new one is welded in its place. Replacement of the rear side members is carried out according to the same scheme. In case of the most severe damage, it is recommended to replace the spar along with a quarter of the body.

How to change the rear spar

Replacement of the rear side member of a VAZ 2110 is carried out in case of visible damage, as well as after an impact in the rear of the car. Of course, the old spar can be straightened or welded, however, after the rapid aging of the metal, it loses its load-bearing capabilities and driving becomes difficult. In addition, rubber wear increases due to body deformation and displacement of suspension parts.

Replacement procedure:

This completes the replacement of the side members. If you decide to carry out such work yourself, be sure to study the welding manual, because an incorrectly welded spar may sooner or later come off and the structure will lose its reinforcing properties. Thus, the car may fall apart while driving, and this, at a minimum, is not safe.
