DIY Niva spars repair

In detail: do-it-yourself repair of field spars from a real master for the site my.housecope.com.

Nowadays, very old cars often come to us, but the owners are obviously very fond of them, and if you build a "Crocodile" from Nyvka, then the rotten body of the car is not a hindrance, and therefore we have to work miracles!

In a word, if you nevertheless bought the Niva “Old woman” and are going to drive it for a long time, carefully examine its bottom for corrosion, cracks in the side members and just through holes on the floor. Pay particular attention to cracks in the side members in the area where the pendulum is attached, the steering gear, the engine beam, the upper bracket lane. shock absorber, long jet rods to the bottom of the floor and the attachment of the “House” of the “Ponar” thrust, do not forget to inspect the shock absorber mount, so that later you will not have problems on the road.

Below are some photos of the rotten and destroyed body parts:

The same inspection should be done by lovers of active off-road driving, even on new cars. frequent cases of detecting cracks in the places I have listed

The work related to the strengthening or restoration of the car body is very time consuming and takes a lot of time and effort, and in your case (if you want us to do this work) ... then money! Therefore, I advise you not to forget about this when buying a “rotten” car for a penny. You will still have to invest in its repair.

Strengthening of the side members and the floor is often carried out with a steel sheet up to 3mm, sometimes 4mm with the simultaneous refinement of the fasteners of the suspension elements, then work on the old car is partially justified since you immediately carry out body repairs and rework if necessary ,namely:

-reinforcement of the front spars with 3mm-4mm overlays (especially important when installing stiffer springs, shock absorbers, large wheels, installing power bumpers and winches, since in these cases the load on the front end increases significantly and the native spars cannot withstand)

-reinforcement of the front shock absorber house

-installation of additional shock absorbers front / rear

-transferring the angle of installation of the rear shock absorber as for 214m and W / Niva

-installation of the A-arm

-transferring the RK attachment from the floor to the subframe to the side members.

-reinforcement or transfer of the floor and trunk side members with a square pipe

-cutting wheel arches and mud flaps for large wheels (at the same time, a rotten cloth is cut off, leaving often still quite a bearable wing)

-installation of power footboards under the "Hijack" in the floor spars

what it looks like in life. I suggest looking at the photo below;

There is no secret work technique here, so lovers of self-processing metal can independently perform all these works if there is a great desire and a place, but whoever is not interested can entrust such work to us. call, sign up, we will help.

It's funny that the spar in French literally means "to go along", and this can be understood in two ways in the context of the popular Internet meme. True, the main meaning of the word is still that in the body of a modern car, the spar is the main longitudinal power element. To verify this, take a look at the drawing of a typical modern sedan, which is shown below.

Typically, two side members run in the combustion engine compartment along the entire body to the beginning of the luggage compartment. The general purpose of these structural elements is to ensure the rigidity of the body; they serve as a frame for the rest of the components. Also, the front side members perform a shock-absorbing function during an accident, since they are located in the crumple zone. Structurally, they are massive rectangular pipes.The poor condition of these elements can lead to a violation of the geometry of the body and suspension, and, consequently, to increased rubber consumption, and, even worse, to a decrease in handling. Due to the low quality of fabrication and poor design, the problem of spars deformation is typical for the VAZ Niva 2121. In our publication, we will consider ways to strengthen and restore collapsing spars on the Niva 2121.

The main reason for the destruction of the side members is metal fatigue resulting from the exposure of the car body structure to variable loads. As a result of the following factors, cracks may gradually appear in the side members (they may even burst, then they will need to be replaced):

Poor road quality
Corrosive processes
Accidents

Cars actively used in conditions of poor quality of roads, even off-road vehicles, are especially susceptible to the destruction of the side members. In this regard, the VAZ 2121, which in many respects "adopted the drawing" of body parts from the "classics" - the VAZ 2106 - endures the hardships of operation in off-road conditions especially hard. Does not compare in strength with the same UAZ. A typical problem of the "classic" Niva is cracks in the front side members. In order to prevent the destruction of the side members, the owners of Niva 2121 cars prefer to strengthen them in advance with the help of specialized kits.

Crack - the final stage of damage to the spar. Appears as a result of metal fatigue. As a rule, latent damage is present in the side members even before cracking occurs. The most costly solution is to replace the damaged side member. It is much easier to reinforce the part with patching and welding. On YouTube, there are a lot of videos of how this is done, including on the Niva 2121. The easiest way is to prevent damage in advance with special overlays.

The main way that the front side members are reinforced on a Niva 2121 car is to install a ready-made set of overlays. Available for sale cost in the range of 3000-4000 rubles, in appearance they are semi-handicraft production. A drawing of a freely available part is simply replicated here. Agree that something more sophisticated in appearance and price for a budget car for off-road driving is better not to come up with. The set includes an amplifier in the form of steel sheets (3 mm thick) and shock absorbers for the brackets (4 mm thick). If you have a surplus of free time, but no money, then you can make the cover yourself, the drawing of the Niva 2121 spar cover for KOMPAS can be downloaded for free on the Internet. But it is better to "carve out" a part based on a cardboard pattern, which can be made on the basis of an existing spar. Then, using a steel sheet with a thickness of 3 mm, the part is cut out with a grinder. Since you will still need access to them, we present an algorithm for dismantling the surrounding Niva 2121 nodes.

All elements are cleaned with a grinder to remove rust and deteriorated metal. This procedure is time consuming, however, correct cleaning in the future guarantees a high quality welding work. The next step will be the manufacture of a lining to strengthen the body element.

For the manufacture of a spar amplifier, experts advise using steel sheets three or four millimeters thick. Initially, according to the drawings, it is necessary to make a model of the product from thick cardboard. It is important to very accurately transfer all the mounting holes to the cardboard and the exact location of the bolts.

If earlier improvements were made to the chassis, the configuration of the fasteners was changed, then it is necessary to supplement the layout with the changed elements. Everything is transferred from the template to the sheet of metal. The overlay is cut using a grinder and an electric jigsaw. Next, you need to drill the mounting holes. It will also be necessary to drill small holes in a chaotic manner on the pad, which will simulate spot welding.

Before starting welding work, it is necessary to check the condition of the spar itself. If it must be replaced, then it must be dismantled by cutting it behind the beam and separating the part from the body. In place of the old element, you must install a new product and tighten all fasteners. Additionally, the fastening points of the old spar are cleaned. Then you can go directly to the installation of the amplifier of the Niva body element.

The prepared trim must be tightly attached to the side member with bolts. Welding is best done with a semiautomatic device. The product is scalded in a circle, and holes prepared for spot welding are welded. Then the shock absorber house is installed and welded. It is important to set it strictly perpendicular in order to avoid problems with silent blocks in the future.

After welding, it is necessary to work through all installed elements and welding seams with mastic. After it dries, the front suspension assemblies are assembled in the reverse order, and the wheel is installed.Reinforcement on the other side of the machine is carried out in a similar way.

The work on strengthening or replacing the rear side members of the Niva is considered more time consuming. Therefore, experts advise starting this process on your own only if you have significant experience in welding and repair work on cars. Replacing and reinforcing the rear body elements is necessary in case of metal wear or after an emergency, if the body behind the car is damaged. To reinforce the rear body parts, as in the previous case, you must start by studying the drawings in order to understand where the elements for modernization are located.

When reinforcing the Niva body, the first element that requires modernization is the side members of the vehicle. It is they who take over all the vibrations of the suspension elements of the machine when driving.

You can strengthen the details both in service centers and on your own, if there is a garage available, preferably with a viewing hole and the necessary tools. Before embarking on self-reinforcement, weigh the pros and cons, as improper work can cost you your life. This is a very time consuming process that requires certain technical knowledge and skills. If you are not confident in your abilities, then it is better to entrust this work to specialists.

Buying a VAZ body is a great chance to save money on an expensive overhaul or buying a new car. It has long been proven that it is more desirable to immediately dispose of a decrepit body for scrap than to periodically repair it in services where they take quite a lot of money for services of this kind. The new body for the most popular Russian SUV is an opportunity for a radical upgrade. On the other hand, if you understand the specifics of body repair, you can carry out the repair yourself.

Today, various companies offer owners of a universal all-terrain vehicle to purchase assembled or metal bodies. Accordingly, the price will differ. In addition, a wide selection of colors makes it possible for each owner to choose their favorite option.

For example, an assembled body for a Niva will cost about 300 thousand rubles, but a skeleton in metal will be almost half the price.

The bodies of the Niva are realized in the following colors.

I have something like this picture

I do not want to amplify, I want to just brew it with a spoon. who will do it and how much will it cost !?

for example like this

Ponimash, it does not rot so pointwise, most likely it is already rusty all over the lodge.
Spatula and reinforce with overlays, if there is something to cook.

Well, I said something like this, but in reality there is just a crack, because it was knocked out of the mud, the bumper was torn out, and the byzgovik cracked, I replaced the torn pipe on the bumper, but the crack on the mudguard should be treated, the crack is only on the mudguard, the spar itself is intact.
I am not against strengthening the spar, if it costs 2000 rubles per side, and not as I was announced 8000 for two, in this case I think that this is a waste of money, because I do not use the car in harsh conditions and for my tasks it is quite enough stock body option.
And I already wentogle these pads and saw the price tag 3500, on the doge, for two pieces of piece of iron with drilled holes

for this money you can take a sheet and cut the linings for the whole Skif club

I hate it when people are trying to make idiots and sell something cheap for crazy money or are these titanium linings?

If we really strengthen the spar as you indicate, then it is much more budgetary to do it like this from improvised means, without buying gold linings

In general, if someone wants to make money and help fix the shaitan machine and knows how to do it, then I do not mind paying reasonable money for the work!

Most often, SUV owners are fans of extreme driving, since the main advantage of the car is its four-wheel drive and high cross-country ability. The consequences of operating a vehicle in harsh and medium off-road conditions are body problems that can lead.

There is only one way out of the problem situation - strengthening the load-bearing elements of the body. The main and first elements that require modernization are the vehicle spars. It is they who take on a huge part of the load when the machine is moving. Let's consider in detail how to strengthen the spars on the Niva.

Most often, the appearance of cracks, tears or rust on the side members is a consequence of a vehicle accident suffered. However, such defects can arise due to the considerable age of the vehicle and wear and tear of parts. Minor cracks and damage to body parts are most often repaired by welding the damaged areas. However, if the product bursts, then its complete replacement is necessary, since it is the main link to which the suspension elements are attached. Most often, when replacing parts, the side members are reinforced in parallel on the Niva-2121, to increase their service life and resistance to loads in aggressive operation.

To strengthen the Niva body element, ready-made linings are most often bought or reinforcing parts are made independently by the owners of the car according to the drawings. They can be found on the Internet, however, if you have all the technical documentation for the car, then the drawing can be found in the documentation set.

It is necessary to start work on strengthening the Niva spars by studying the current situation. To do this, you need to open access to the body element. The car must be driven into a pit or overpass, remove the wheel, caliper and unscrew the ball nut. The front suspension assemblies are disassembled for a longer time, the shock absorbers and the upper arm are removed. After that, it is necessary to unscrew the stretch that secures the beam and the spar, the shock absorber house is dismantled.

The prepared trim must be tightly attached to the side member with bolts. Welding is best done with a semiautomatic device. The product is scalded in a circle, and holes prepared for spot welding are welded. Then the shock absorber house is installed and welded.It is important to set it strictly perpendicular in order to avoid problems with silent blocks in the future.

After welding, it is necessary to work through all installed elements and welding seams with mastic. After it dries, the front suspension assemblies are assembled in the reverse order, and the wheel is installed. Reinforcement on the other side of the machine is carried out in a similar way.
