DIY body repair 2104

Details: DIY body repair 2104 from a real master for the site my.housecope.com.

No sooner had I finished with the cornfield than another job appeared. They drove me a four with very serious damage to the metal by corrosion: the thresholds, partly the bottom, parts of the wings connecting to the thresholds, and in general the car is all covered with specks, rotted into dust, so the work is not easy, and not cheap for the client, I would go to his the place did not bother with this machine, since the repair is essentially equal to its cost, well, since the client needs it, then we will do it. The car is by the way 2000.

Dismantled the entire interior to get to the bottom and evaluate the upcoming work in more detail:

I cut off the wings, initially I thought that the wings were native, since the welded points of resistance welding are all in place, but it turned out to be more and more interesting: someone changed the wings not by welded points, but a little further, that is, the old wings were partially left, to them new iron was welded, the welded seam was putty, when I removed the wheel arch liners, it was clear that the wing was welded to the apron not by contact welding, but by a continuous seam) Since the apron was badly rotted, and initially I hesitated to change it or not, when I saw this welded the seam from which I was tortured to separate the old wing, it was decided to change the apron.

By the way, a little humor: the owner tells me this, you give it to me so that everything is fine, otherwise there was a case they gave the car, then they rode on it and broke it ... I say everything will be fine, do not worry! The owner is just leaving, I drive the car into a fence, but after that I decided to put it on a pit, otherwise, you never know, the dog will break off all the mirrors, began to drive and fell with one wheel into the inspection pit)) nothing in principle is terrible, I slightly crumpled the front wing, which it still changes, the only thing was tormented to get it out of there, the whole car is rotten, there is nothing to put a jack for, but after killing an hour, the car was released)))

VAZ-2104, popularly known as the "four" is a Soviet and later Russian passenger car of the station wagon type based on the VAZ-2105, which replaced the VAZ-2102 in the model range.

"Four" was produced from 1884 to 2012 at the Volzhsky Automobile Plant.

Then VAZ-2104 was produced in Izhevsk, and entered for SKD assembly at Ukrainian factories "Bohdan"And" KrASZ ". When creating this model, the designers were faced with the task of achieving the maximum consumer effect at the lowest cost. The first samples of the "four" were not even equipped with a rear wiper and heated glass.

Note that there was even an export version VAZ-2104.

A later version of the VAZ-21047 was equipped with a five-speed gearbox, partial power accessories and a salon with anatomical front seats from VAZ-2107... And from 1999 to 2006, even a modification of the VAZ 21045 was produced with a diesel power plant with a volume of 1.52 liters. The "four" has a roomy interior, moreover, the useful volume of the trunk is increased due to the folding rear seat. Despite the outdated design, the car is simple and reliable in operation, as well as an affordable price.

VAZ-2104 is perfectly adapted for the transportation of both goods and passengers. And the tailgate connector along the floor line does not create unnecessary inconvenience when loading or unloading. The car is great for long journeys and city trips.

The popular domestic rear-wheel drive car VAZ, the so-called "four" has long been a success. The reasons people buy it are:

Quite a simple body;
Relatively cheap spare parts for VAZ;
High capacity;
Good strength of body parts

Based on these qualities, the VAZ 2104 can be confidently called a people's car. The features of this car dispose to its use as a cargo-passenger transport. For a family, this “horse” is very important, since the availability of the necessary luggage requires an increased volume for its transportation.

It is much easier to renew or restore the VAZ anti-corrosion coating. The location of the plots can create an inconvenience. But this problem can be solved. It is enough to have a viewing hole. It is better to buy bitumen-containing products as coatings. Currently, there are many good, high-quality auto chemical products that have proven themselves from the best side. It is quite reasonable to check the condition of the bottom coating of your VAZ 2104 every year. The stones and sand flying at high speed have their destructive effect on the coating layer. It is better to check the condition and restore the VAZ coating in the warm season and after the bottom dries out from moisture.

The moving parts of the body are the doors (side and rear) and the bonnet. Among the common malfunctions of the VAZ 2104 doors, the following can be distinguished:

Close and open poorly;
Poor adhesion of doors to the body;
Fastening faults.

The first VAZ malfunction can be eliminated by checking and replacing the door locks, as well as by repairing the opening and closing mechanism located inside the VAZ 2104 door.

Loose fitting of doors is eliminated by adjusting the position of the lock and changing the position of the door by displacement relative to the hinges.

Fastening faults include backlash in the hinges and deformation of the corresponding sections of the doors. You can eliminate it by replacing the hinges or restoring the shape of the door sections. Although this is rare with this VAZ model, lock adjustment is more common.

There are mainly two factors leading to damage to body parts:

Corrosion effect on the body;
The result of the accident.

The weakest points of the VAZ for corrosion are the lower parts of the doors, thresholds, the bottom, the edges of the fenders. Replacement is carried out by destroying the welded joints and separating from the body.

When installing a new element on the body, the fastening surface is prepared. It usually consists in removing old welding, cleaning, applying a layer of a protective coating against corrosion. It is also possible to straighten and straighten during the installation process. The installation of new elements of the VAZ 2104 is carried out by spot welding with an interval of 4-5 cm between the points. After completion of the installation, preparatory work and painting are carried out.

The process of repairing a VAZ is always associated with the cost of money and time. Therefore, first calculate your resources so that the restoration project is within its reach.

Good luck in the repair!

Many owners of the VAZ 2104 car, this well-known model of domestic production, value their iron horses and want them to retain their attractive appearance for as long as possible. Body painting and repair plays an important role in this.

The cost of such work in specialized workshops is quite high, and therefore most people prefer to do them on their own. It is painting that will be the topic of further conversation. For convenience, we will divide this process into several stages:

repair of body elements;
grinding;
choice of paint;
preparation for the process;
staining.

This stage is the first and perhaps the most important in the whole process. Body repair VAZ 2104 begins with the most common wash, during which it is cleaned of various contaminants and debris. It is advisable to wash the bodywork with the use of various synthetic detergents, which will not only facilitate the work, but will also reveal various minor defects.

The painting of the car must be carried out with the decorative elements and glass removed. Therefore, it is more expedient to dismantle locks, bumpers, moldings, tuning elements of the VAZ 2104 at this stage.

Many people prefer to paste over them with special masking tape. However, this should not be done, since the condensation accumulated under it can damage the decorative coating applied subsequently.

If serious defects are found, it is advisable to repair the body using a straightener and a welding machine. All neglected disadvantages subsequently appear under the decorative layer and their elimination will require additional costs of both forces and funds.

At this point, the first stage of the staining process for your VAZ 2104 can be considered complete.

After the body repair is completed, you need to start grinding it. Stains and old paint residues are removed from the surface of the car and areas affected by corrosion are cleaned.

Then the VAZ 2104 body is primed. It is carried out in the following order:

The selection of paint for VAZ cars usually does not cause difficulties and depends on your preferences and financial capabilities. If you prefer a matte finish, a single coat can be used. The metallic color will require the purchase of two-component paints.

Particular attention should be paid to the selection of the shade in the case when it is necessary to paint only a certain part of the body. In this case, it is more advisable to use the services of specialists who have at their disposal specialized equipment that allows you to achieve the best results.

Not only the appearance of the surface, but also the durability of the applied coating depends on the correct mixing of the various components of the paint. The correct proportions are indicated by the manufacturer on the packaging. Usually, for three liters of enamel, 2 liters of primer should be taken. The remaining 1/6 is taken up by the solvent.

The application of the prepared mixture to the surface of the car body is carried out in a room protected from dust and exposure to direct sunlight. It is best to use a special spray that is purchased from specialized retail outlets.

The paint is applied in layers until the required surface quality is achieved. Each of them must dry out before continuing the process.

It should be noted that the viscosity of the paint should decrease from layer to layer. In this way, defects in the applied decorative coating can be avoided.Drying can be done in the same room where the staining took place or use special cameras. The latter option is preferable, however, it requires additional cash costs.Painting and repairing a VAZ 2104 car does not cause any particular difficulties and requires only a minimum set of skills, which allows them to be carried out on their own. The final result depends only on your accuracy and patience.With due diligence and attention, the car will not only serve you properly, but also please the eye with an excellent appearance. I propose a way to restore the bottom of a car without overcooking and in normal garage conditions. I do not pretend to be the author of the idea, although the idea was born myself 🙂 If we compare the costs of capital welding, then this method is incomparably cheaper. It is certainly not perfect and is unlikely to suit those whose body has already rotted into "dust". And so - think for yourself, decide for yourself - to have or not to have.For this we need:
Materials:
- galvanized iron in sheets (2 sq.m.);
- antinoise bitumen mastic (2 cans);
- bolts, nuts, washers M5;
- self-tapping screws 15-20mm long
Equipment:
- angle grinder (in common people, a grinder);
- drill
- screwdriver
- scissors for metal;
- roulette;
- brush 100mm wide;
- permanent marker;
- metal brush;
- cutting and grinding wheels.
Details:
- Small front side members right and left

And so, let's get started.
First you need to understand the interior: remove the seats, floor mats, remove the noise insulation. I have only one name left from Shumka :).
Next, you need to remove the old bituminous mastic from the floor in the cabin. this is necessary for a more detailed assessment of damage and marking of sheets. it is also necessary to remove the exfoliated mastic from the bottom of the bottom.

The rot is already cut off in the photo.

Due to the presence of a "grinder" I cleaned the "live" part of the floor to metal. The only jamb - after a couple of passes through the uncleaned mastic, the petal circle clogged up and no longer cleaned it, but polished the rust, it had to be replaced.
In the end, it turned out something like this:

After sanding and trimming everything that is superfluous, we begin to cut the tin. Here, everyone has their own injuries. I covered the entire half from the inside, right down to the transverse spar, although the floor was intact there. The fact that there is a stamping in the floor does not really matter, later it will be possible to pour mastic there and everything will be a bunch. In any case, the tin did not work for me from this.
After cutting the material for the inner part, we cut the tin for the bottom. Here, again, your personal wishes, the amount of galvanizing available and the nature of the damage play a role.
After cutting the metal, coat the floor with bituminous mastic (from all sides). It is advisable to let the mastic dry so that the layer of mastic will eventually be larger. I had to dry for a week due to working days.

Galvanizing installation.
Before installing galvanized sheets, we generously smear them with mastic (by the way, it is better to make the mastic thicker, otherwise it flows strongly) only from the installation side, otherwise then all the mastic will be smeared on hands and clothes.
It is better to fix galvanized sheets intended for installation from below with self-tapping screws to the bottom, especially if you do not have an assistant. The protruding parts in the cabin must be cut down. Then we climb into the salon, put the galvanized steel (again, oiled with mastic) on the floor and begin to fasten it with bolts. In principle, M5x15 bolts are enough for the eyes with the obligatory use of washers on both sides. When using self-locking nuts, the lock washers can be omitted (only regular ones). If the nuts are common, then the growers must be installed. The drill must be taken with the same diameter as the bolts.
It is better to fasten it to start from one end, since the possibility of metal bending is excluded.I didn't do that right away and had to rebuild the structure.
How many bolts and location to choose according to the situation. If you have to replace the front spar ("jack"), then in this place the sheet is not yet fixed.

Installing the front side member
Preparation of side members:
I removed the hinges for the standard jack, I think very few people use a regular screw jack.
Drill six holes on the long crown attachment petals (three on one side and three on the other).
We apply the spar to his place of permanent residence and squeeze it from below. Better jack.
We drill holes in the floor through the spar. Then we remove the spar, coat the inside of the spar with mastic and the section of the bottom that will be closed by the spar and put the spar. We fasten again with bolts.

As a result, we got something like this:

the protruding parts of the bolts can be cut off.
In conclusion, we cover the galvanized sheets with mastic, trying to push the mastic into the cracks, if any, the spars and all places not covered with mastic.
I think this design will last longer than a digested bottom.
Now let's summarize the financial result of this venture (the repair was carried out in the winter of 2009-2010):
- galvanized iron 2 sq. M (350 rub.)
- bituminous mastic 2 large cans (360 rub.)
- side members 2 pcs. (200 rub.)
- bolts, nuts, washers, screws (about 80r.)
- cutting disc 1 pc. (15-20r)
- grinding wheel (60 rubles)
Total: approximately 1070r.
Plus an invaluable feeling of what I did myself :). The service asked 15 thousand rubles for overcooking the bottom.

I hope that this manual and idea will be useful to someone.

Inspection and straightening of parts and body elements in most cases is required in emergency rooms.

Installation for inspection and repair of bodies VAZ 2105 with a device for straightening
1 - installation frame
2 - body
3 - bracket for fastening the cross member of the front suspension
4 - an anti-roll bar mounting bracket
5 - straightening device with boom and hydraulic device

The control of the geometry of the attachment points of the chassis of the VAZ 2107, as well as the check of the control points of the floor of the body of the VAZ 2104 can be performed at the installation for the control and repair of bodies.

Straightening of deformed bodies can be carried out using straightening devices. The device is fixed to the installation frame from the side of the deformed part of the body.

Deformations are eliminated during installation:

- body floor;
- front and rear side members;
- mud flaps of the front fenders;
- front and center pillars;
- trunk floor;
- panels of the front and rear of the body;
- outer and inner rear wheel arches.

Damage to the body of the VAZ 2105 can be very different. Therefore, the repair rules in each individual case should be different, the most suitable for these damages.

In almost all cases of damage, it is necessary to remove some parts in order to detect damage, straighten and align the body.In cases of serious damage, remove all easily removable interior upholstery parts to facilitate the measurement, control and installation of hydraulic or screw jacks to eliminate distortions and deflections of the fret classic.

Reference linear dimensions of the openings of the wind and rear windows

By editing it is necessary to restore the original linear dimensions of the body frame. The diagonal dimensions of the window openings should be 1375 ± 4 mm for the wind window, and 1322 + 4–2 mm for the rear window. The distances between the flanges of the window openings along the axis should be equal for the wind window 537 + 3 mm, for the rear window - 509 + 3 mm.

The difference in the diagonal dimensions of the openings of the wind and rear windows, as well as the openings of the hood, trunk lid of one body should not exceed 2 mm.

Most often, when repairing the frame, it is necessary to replace the fenders, roof panels, front and rear. The methods of replacing and repairing these parts can be taken as a basis for repairing other body parts of the VAZ 2107. You also need to know the location of the welds.

The Kia Quoris is the original rear wheel drive sedan that was made thanks to the Hyundai Equus. The first premiere of this car was back in 2012. The name K9 was used for the presentation, which created certain hidden elements. Under the name Quoris, the manufacturers decided to offer this car on the markets in the USA and European countries. But, at home and in other Asian countries, the company decided to keep the old name K9. The first exit for the car became questionable, because critics and spectators noticed a large number of similarities with the BMW 7 Series.

The first advantage of the Peugeot 308 after the car has undergone restyling is its appearance, which has become much more effective and original in comparison with the previous version of this model. The dimensions of the air intake, which frankly spoiled the appearance of the car, were significantly reduced, it became more laconic, which had a positive effect on the global impression that the car leaves. The exterior of the car hints at its aggressive character and sporting ambitions.

Cold winters will always replace hot summers. Moreover, our winter is always frosty, snowy, and in the summer the sun always beats down. To protect oneself from this all-consuming heat, a person must try. A pedestrian, for example, can walk during a hot season. Follow the shade, or take a bus, taxi or metro to the nearest lake or river. But it is more difficult for car owners to cope with such a task. Drivers spend most of their time in their cars.

So, you need to share with everyone how the body repair of the VAZ 2104 was done. The car got to the owner decent and served as a decent horse. It was possible to ride it anywhere, the main thing was that there was a desire. Recently, the son of the owner of this car received a license and thus began to ask for a car. A new car, of course, cannot be given to him, so it was decided to make a tuning of the VAZ 2104 so that the kid could ride. We went to the store together and bought the necessary materials. A lot was bought in total and the list is presented below.

1) Putty
2) Spatula
3) Sandpaper
4) Metal brush (Grinder attachment)
5) Solvent
6) Paint (to match the body color)
7) Primer
8) Patience
9) Time

So the car was not in very good condition before it needed to be repaired.

This problem needs to be solved and, moreover, an urgent tuning of the VAZ 2104 must be done. To begin with, the car was driven into the garage and an assessment of the general condition of the car began. Using a metal brush, you need to clean out the places where rust has formed, and you need to clean it to clean metal.

It is not possible to completely remove corrosion with a brush, so in this case you need to use sandpaper at the end. So, the stripping process is complete. Now you need to proceed directly to the putty.Before carrying out work, the body must be cleaned of dust and dirt. We wash off the dirt and wipe the car dry. Degrease the surfaces one by one. As a first layer, putty can be applied without sparing it, especially if there are deep dents. The main thing is that the dent is filled.

We do the same work with other surfaces. A very difficult area is the bottom of the doors, because this is where a lot of corrosion appears. When the corrosion is removed, then a bare metal area remains and there is simply no point in sculpting putty there. In this case, the construction mesh comes to the rescue. We fix it with ordinary self-tapping screws and apply a layer of putty on top.

Now we completely level the entire body with putty, especially where there were dents. We skin the entire body and wash it. Now the repair work is over, the soil and the paint itself remain. This procedure is very difficult because it can often create drips. It is best to trust the painting to professionals in their field.

The opportunities that open up to the car owner allow you to transform any car, make it even better than it was before. Owners of domestic cars are also actively interested in such opportunities and are actively using them in practice. Today we will consider tuning the VAZ-21043, we will analyze the possible options that can be applied in practice.In the process of tuning the well-known "four" from VAZ, most attention is paid to changing the body. Its design is no longer considered attractive and modern, now this angular shape looks outdated and unattractive. You can tune the body in several versions, which differ in cost and volume of work:

the easy one consists in replacing the radiator grille, tinting the windows, installing disks on wheels and Vihur skirts;

with an average body tuning, it will be necessary to install alternative optics, replace the body kit, think about the likelihood of ordering professional airbrushing and shaving, which consists in removing handles, locks and moldings;

deep, as you might guess, is the most difficult, expensive and time-consuming, because it requires changes in the body structure, for example, changing the roof level, reworking into a coupe, installing lambo doors.

Even an easy tuning option will transform the car's appearance. Glittering chrome on the body, solid tinted windows, rare or, conversely, ultra-modern wheel caps - and your car will already look decent on the road.And if you take a more serious approach to the transformation of a domestic car and decide to "truncate" the body, then you can get a small-sized car on which you can deftly drift and easily maneuver. To get such a powerful baby, it is necessary to remove part of the passenger compartment and reduce the length of the propeller shaft. It is not worth hoping for significant fuel savings, consumption will decrease, but not as significantly as we would like. Now you need to do the electrical wiring, shift the brake lines, carefully close everything and repaint the improved body. Another drastic solution is to move the spare wheel to the trunk lid. But this design, as they say, is not for everybody.

The body structure can change not only in length, but also in height. Usually, the height of the passenger compartment is lowered by a maximum of 15 cm. This result can be achieved by cutting off the struts, changing the front bumper, as well as rear lighting. The exterior in this case changes dramatically. It will not be easy to get used to this size of the car.If you are lucky enough to ride on perfect asphalt, then you can transform your VAZ-2104 in the rare Stance style. Its essence lies in the installation of short springs and discs of small diameter. A car with such changes is quite rare, so your VAZ-2104 can become a unique copy.A more popular form of tuning is body lift, which is the opposite of the Stance. Such a car can easily overcome bad road sections and even off-road terrain.The controversial point is the need to strengthen the body support pads. This moment cannot be called mandatory, but it is still better if it is implemented. No one will get any worse from this. The installation of stiff springs, which is provided during the tuning process, requires reinforced metal. For the front suspension, you can choose springs from the Volga, and the rear shock absorbers can be taken from the Gazelle front end.Seriously, you need to think about installing air bags that will not allow the body to swing, and will make the ride softer. Air bags are installed inside the springs. A similar element can be added to the lifted and standard body, its work will not change from this.Body paint is an important element in any tuning. Still, this parameter is most striking and is able to distinguish any car. There are several ways to solve this problem. You can go the standard way and cover the body with ordinary paint with an interesting effect (metallic, chameleon, matte, glossy). One of the new solutions is liquid rubber. Such coloring will not only make the tuned car expressive, but also protect the body from external influences. Airbrushing can be used not only on expensive foreign cars, but also on models of the domestic auto industry. It is better to entrust such coloring to specialists who have extensive experience in this area and will be able to transfer any imagination to metal. Airbrushing requires compliance with the declared status, and if you have already chosen this method of transformation, then a clumsy roof rack, old wheels or a rusty trailer will make the car ridiculous and tasteless.There is as much work to be done inside the car as outside. By internal tuning, we mean bleeding the engine, replacing the braking system and modifying the interior. But first things first.Tuning of domestic cars is embodied not only in external changes, but also in internal ones. Believe me, there are many parts under the hood that need reorganization or complete replacement. The main element of any car - the engine - is primarily subject to tuning. If your car has a native power unit that has faithfully fulfilled its due date, then it is better to send it to a well-deserved rest, that is, to scrap metal. Still, the metal is pretty tired, and even physical deterioration takes place - these factors do not allow us to talk about further refinement and forcing. There is only one conclusion - the old engine, which has unscrewed several circles of the speedometer, must be replaced, and more work can be done on newer units.A worthy replacement for the old engine will be a powerful unit taken from the VAZ-21213, its volume will be 1900 cm3. Its power can be increased from 79 to 120 horses, but it will take some effort and part with your hard earned. The forcing process consists in boring channels, grinding the intake manifold, installing cast pistons with a diameter of 82 mm. To change the valve timing, it will be necessary to purchase a new camshaft, with which it will be possible to lift the valves up to 10.8 mm.When using a sports crankshaft by 88 mm and increasing the level of piston lift, it is possible to increase the volume of the power unit and facilitate the removal of the increased force that occurs during the combustion of the fuel-air mixture.Installing a lightweight flywheel will allow you to reduce the loss of power, which is spent on spinning the motor. As a result, the car will pick up the required speed in a short time.The exhaust and power system are also in need of modernization, which includes the installation of an air filter, a sports exhaust manifold and a straight-through muffler.It remains to modernize the brakes, which are responsible for the safety of the driver, his passengers and other road users. The drum brakes, which are available on the rear axle in the VAZ-2104, are difficult to operate, and even not effective enough. Replacing them is a must; 13-inch ventilated disc brakes are well suited for this.The effect of all external changes that have occurred with the VAZ-2104 will be irretrievably damaged by the outdated interior. Internal tuning is just as important as engine upgrades and bodywork. Everything can be very simple here. If the seats are in good condition but look shabby, the upholstery can be replaced. With enough funding, you can opt for leather material for the upholstery, but any other material will look good too. Carbon fiber décor is a great way to enhance the tuning effect and make the interior more expensive.
