Repair of body thresholds from dents and rust in Moscow

The car body is constantly exposed to mechanical stress, and some parts of the body often experience chemical attack. Parts of the car body such as sills are subjected to this ordeal every day. These elements serve not only as decoration. They provide the body with additional rigidity and help withstand torsion loads and “break” loads.

In addition to the mechanical impact, thresholds are also negatively affected by reagents - salt, etc., which are used liberally on the road surface in winter. Due to the treatment of asphalt with chemicals, the thresholds are destroyed. Corrosion slowly but surely thins the metal from which these elements are made, and over time they turn into dust. It is the threshold that is most often subject to replacement, since it has a short service life. But where can you find a technician or car service center that will replace the thresholds of a VAZ car in Moscow with quality and with guarantees?

Procedure for replacing thresholds on a VAZ 2107

Old rotten thresholds have to be cut off with a grinder. To provide access to the entire surface of the threshold, the doors must be removed. If the body is decrepit, spacers must be installed before removing the sills. Further operations are performed in the following sequence:

1. Cut off the outer parts of the thresholds with a grinder (you can use a chisel or a metal saw).
2. Check the condition of the threshold amplifier (a wide steel plate with holes around the perimeter).
3. If the amplifier is rotten, cut it off with a grinder.
4. Remove the remains of the thresholds and reinforcement from the seams of the body.
5. Clean the surface for welding, removing any unevenness and dirt that would interfere with a quality connection.
6. If the old threshold amplifiers had to be dismantled, try on new ones and adjust them to the seat. Drill holes with a diameter of 4-6 mm at intervals of 50-7 mm around the perimeter of the amplifiers.
7. Weld the amplifiers, having previously secured them with clamps. Start welding from the middle pillar, welding the upper and lower parts in parallel to the body.
8. Try on the thresholds. Cut off all excess from them and bend them, giving the desired shape.
9. Remove primer and paint from parts of the threshold in the places where the welding seam will be.
10. Pre-fix the thresholds with self-tapping screws.
11. Install the doors, check the correct fit of the thresholds, paying special attention to the gap between the doors and the thresholds.
12. Weld the sills, starting welding from the B-pillar. It is necessary to weld the lower and upper edges of the threshold in parallel. This is a critical operation that determines the rigidity of the car body. Therefore, you need to pay special attention to the quality of welding seams.
13. Clean weld seams and threshold surfaces.
14. Fill traces of welding seams.
15. Prime the outer surface of the thresholds and allow the primer to dry.
16. Paint the sills.

Tips for replacing thresholds and protecting them during operation

1. Instead of paint, you can use a Gravitex-type anti-corrosion coating.
2. After replacing the thresholds, they must be subjected to anti-corrosion treatment by “blowing out” the inner surface of the boxes with Movil. If this is not done, the thresholds will have to be replaced again in the near future.
3. The lower part of the thresholds (including the bottom of the car) should be treated with anti-corrosion bitumen mastic, which prevents corrosion and improves the protection of the paintwork from damage.

[/tip] Now you know how to replace the thresholds of a VAZ 2107 yourself. If you do not have the necessary qualifications as a welder or do not have a welding machine, you will not be able to replace the thresholds. In this case, it is better to seek help from professionals who will replace the thresholds quickly and efficiently.

Car thresholds are a spare part that is highly susceptible to wear. VAZ 2107 car owners often need to overcook this part. Such a service in Russia can be ordered for approximately 5,000-15,000 rubles .

How are car sills repaired?

Sequence of work for removable thresholds:

1. Dismantling. The thresholds are removed by unscrewing the bolts that hold them in place;
2. Elimination of deformations. The threshold is returned to its previous shape;
3. Metal thresholds are treated with an anti-corrosion compound so that the repaired threshold is not destroyed due to exposure to an aggressive environment;
4. Painting. At the final stage, paint is applied so that the threshold has a beautiful appearance.

List of works for fixed thresholds:

1. Damaged areas are “stretched” to return them to shape. In case of serious defects, it may be necessary to dismantle and install a new threshold;
2. At the last stage, anti-corrosion treatment, masking of welds, priming and painting are performed. Additionally, the threshold can be coated with anti-gravel.

What is this?

Re-welding of thresholds on a VAZ 2107 is understood as a service during which a car mechanic restores a worn-out trim by re-welding, straightening, and painting. Thresholds are highly susceptible to the influence of various negative factors: shock, contact with reagents, water, temperature changes. All this leads to the fact that the paintwork is damaged, and the metal begins to become covered with rust.

Thresholds perform a protective function: they prevent the formation of cracks, dents, and abrasions on the car fender.

You need to order this service in the following cases:

• The spare part is severely deformed.
• The part is covered with rust.
• There is a large amount of damage that cannot be repaired by pulling out the metal.

The damaged threshold can be replaced with a new one. But, as a rule, this is more expensive than overcooking.

Digestion is performed using special tools and equipment. The work is painstaking and troublesome. Therefore, it is better to order such a service from professionals. To do this you need to do a number of steps:

1. Choose a suitable service station.
2. Call the administrator and find out the approximate price of the work and terms of cooperation.
3. Arrange to come to the master.
4. Bring the car to a service station for repairs.
5. Wait until the specialist finishes the work.
6. Accept the restored threshold.
7. Pay the auto mechanic.

In what cases is threshold repair required?

The main reasons why threshold repair is required include:

• Corrosion due to exposure to chemical reagents;
• Incorrect use of the jack;
• Sloppy parking on the sidewalk;
• Road traffic accident;
• Careless driving on rough terrain.

Because of all this, dents, scratches and areas damaged by corrosion can form on the thresholds.

Pricing factors

The cost of the service for re-welding thresholds on a VAZ 2107 varies greatly in different places. This is explained by the influence on the price of such pricing factors:

• Type of damage.
• The material from which the spare part is made.
• Number of overlays to digest.
• Difficulty of work.
• Type of welding.
• Tools and equipment used.
• The need for a mechanic to visit the vehicle's location.
• Urgency of order implementation.
• The need for additional work (for example, straightening, painting, strengthening, gluing with protective film).
• The need to dismantle the linings.
• Auto mechanic qualification.
• Prestige of the auto service center.
• Quantity and cost of materials used.

What does the price depend on?

Different car repair technicians perform over-welding of car sills for different amounts of money. The price is formed under the influence of various factors:

• Type and area of ​​damage.
• Repairability of the lining.
• Threshold material.
• The number of thresholds that need to be digested.
• Welding method.
• Price of consumables.
• Car model and make.
• Need for dismantling.
• Urgency of work completion.
• Additional work (straightening, painting, gluing protective tape, treatment with a special compound, reinforcement).
• Price for a specialist visit.

Types of services

The service for digesting thresholds on the VAZ 2107 is classified into certain types according to the following criteria:

1. According to the performer, professional and independent.
2. According to the time allocated by the client for the execution of the order for urgent and non-urgent.
3. According to the material used to manufacture the linings for overcooking, aluminum, steel, and alloy thresholds.
4. If necessary, remove the linings for work with or without dismantling.
5. If necessary, subsequent processing includes overcooking with polishing, coating with protective compounds, and gluing of a special anti-gravel film.
6. At the place where the service is provided: in a service station, in the garage of a private master, at the address where the car is located.

Body repair methods

At one time I tried different methods of body repair, I’ll give a little story from my experience

• Simple cleaning with brushes, sandpaper, patches on the bottom were made using rivets with further application of anti-corrosion agents, the method is less labor-intensive, not very reliable, and it only lasted for 1-1.5 years maximum, after which the repair areas began to become covered with rust again.

• Using acetylene, creating this gas by interacting carbide with water, the generator was made from the wheel chambers of the Urals, later a factory acetylene generator appeared, the method is already more reliable, but the problem is that it is not comfortable to work with carbide in a garage (room) from a safety point of view. for health and physically.

This article is about the third method. In 2022, the time has come to repair the body of my VAZ 2112 car. Finance sang romances about the new car and I decided to look on the Internet to see what modern equipment exists for repairs and how much it will cost me.

Basic list and price of necessary equipment for car body repairs

• The MIG MAG welding machine (semi-automatic) is suitable for both seam and spot welding, preferably with charging a spool of 5 kg welding wire and a roller for drawing wire 0.6 - 0.8 mm (price category from 15 to 60 t.r.) which I use The Atom I-180 MIG/MAG device, this 3-in-one device is quite reliable and has been helping me in my work for the 3rd year already).
• A compressor from 6 to 10 kgf/cm2 with a flow rate from 300 to 450 l/m, I recommend with a belt drive, these are one of the most reliable compressors (from 18 to 40 tr) I myself use KRATON AC-300-50-BDV for garage work I have enough of it
• A carbon dioxide cylinder, preferably 40 liters. (in my case it took two full refills) (from 4 to 7 t.r.)
• A grinding machine, the criterion for speed is not critical since it is needed at low speeds, but for a power of at least 1000 W, I recommend, of course, a pneumatic machine, these machines are more wear-resistant and do not require time to cool down after long-term operation. (from 800 to 2000 rubles)
• A drill, preferably from 0 - 2000 rpm, with a power of 500-800 W is enough with adjustable speed. (from 800 to 2000 rubles)
• Two spray guns, one for priming and the other for paint and varnish chemicals (from 600 to 1000 rubles)
• Clamps or clamping pliers with gap adjustment, preferably 6 pieces, are needed to fix the thresholds.
• Grinder for 115-125 mm wheels
• Grinding machine for discs 115-125 mm
• Chisel, or a powerful flat-head impact screwdriver.

Repair consumables

• Sandpaper with grit from 180 to 5000, for different stages of work.

• 2. Drills with a diameter of 4 to 6 mm, mainly needed for drilling out old thresholds.

• 3. A sheet of metal 1 - 1.5 mm, you can use metal from old household appliances, often someone throws something away from friends (refrigerator, washing machine, etc.) or dissolve a metal 200 liter barrel, there are many options, if only you could use your imagination, metal necessary for bottom patches.

• 4. Welding wire, it took me 7 kg for two thresholds and patching the bottom

• 5. Putty for metal, anti-corrosion and paint and varnish materials, the market is very diverse, if anyone is interested in which ones I used, I will answer in the comments.

• 6. Paper tape, film for covering parts not subject to painting.

• 7. Cutting and grinding discs for grinders

Well, I can’t help but remind you about the purchase of PPE (Personal Protective Equipment), namely the organs of vision and breathing in the first place, since during this work harmful substances are released and used.

Don’t forget, take care of your health, which you can’t buy with any money.

In this list of equipment, I didn’t include sandblasting because I worked without it, but ideally it definitely wouldn’t hurt, since with such work it’s not often, but still there are places where you can’t get anywhere except with the help of sandblasting, I’m in such places I just used a “zincar” sprayer, which supposedly removes rust and immediately galvanizes, although I’m not a fan of such chemicals, but where could I go?

A car threshold, as everyone knows, consists of 3 parts, internal, external and a threshold amplifier, but when replacing thresholds, few people pay attention to such a detail as the rear heel of the threshold and believe me, it rots at the same time as the threshold, and if you decide to take on such work then I advise you to purchase this part, I also forgot about it, and so as not to order and not wait for another order, since I live in a city where there are no body parts stores and the nearest one where it is possible to purchase is 170 miles away, and I decided to bend this part and bring it out myself, below at In the photo you can see this process, although the cost of the part is quite low; for a VAZ 2112 in 2018 it cost about 400 rubles apiece.

If desired, you can bend and restore almost any part and smooth out all minor defects with a primer, but this process significantly increases the repair time.

Where to start body repair

First you need to prepare the car for work; for the convenience of replacing the thresholds and patching the bottom, I advise you to do the following:

• Remove all doors
• Remove the seats
• Remove air ducts
• remove the floor covering, the lower part of the covering is also sound insulation and thermal insulation, it is often damp, I advise you to throw it away as rust oxides remain on it, instead buy a new one, I used an old clean carpet.

• Collect all the bundles and move them away or, if possible, tie them, that is, protect them from damage during work.
• It is necessary to drain the fluid from the engine when you turn the car over on its side to repair the underbody, unless of course you need it.
• Disconnect and remove the battery
• Disconnect the fuel (supply and return) pipes.
• Drain the fuel tank for safety reasons during operation.
• Remove the bumper

After the above work, it was time to more carefully assess the damage to the bottom, removing all the insulation, we got to the metal.

After the assessment, you have decided on the scope of work, you already know exactly how much metal is needed on the bottom, etc.

The assessment of damage to the thresholds will only be visible when you open the external threshold

After the car is ready for work, you will of course ask where to start, I advise you to start with the thresholds, one by one, after finishing one side completely, move to the other.

I don’t recommend cutting or drilling out two thresholds at once since this is a stiffening rib, I don’t think it’s worth explaining the possible consequences.

But this is if you decide to change both the internal and external thresholds completely, as I did, often many who replace thresholds do not touch the entire internal threshold, but partially repair the threshold itself, cutting out the corroded (rotten) part of the threshold and take the cut out places donor from a new threshold.

Useful tips when replacing a threshold

• It is easier to bend a metal part according to a layout cut out from cardboard; if the part is complex, bend the sample along the worn part before removing it; if you still have no idea how to bend a complex part according to the layout, then divide the part into several simple fragments for further welding, as shown in see me above using the example of the heel of the threshold in the picture in the article above.
• Choose a new threshold with a thickness of at least 0.8 mm, this is the manufacturer’s thickness, or I advise you to set it up to 1.2 mm, thresholds with a thickness of 0.6 mm are often found, this is below the manufacturer’s standard
• As you work, do not forget to treat areas with an anti-corrosion agent that will later be impossible to reach.
• In place of the factory threshold amplifier, I advise you to cut and install your amplifiers with 3 - 4 mm of metal without making any stiffening ribs, installing them at three points of the threshold, the first under the front pillar, 5 cm away from it, the second under the rear arch pillar, and the third under central pillar, installing all three amplifiers across the entire width of the threshold, 14 cm long, and this is quite enough.

• If you want to give your car a second life for another 8-10 years, then if possible, remove completely rusty metal and completely re-cook the rotten parts.

• If you decide to change the entire bottom rather than patch it, then you will also need to remove the torpedo, but from practice I can say there is no need for this, unless, of course, your bottom has completely turned into dust.
• Do not treat with cheap anti-corrosion agents, for example old-style ones; nowadays the market is diverse and there are more modern and high-quality treatment agents.
• It is advisable to weld the threshold from the central pillar, gradually leveling and pulling it out using clamps.
• The distance between welding points is 5 cm.
• After finishing the work, don’t forget to fill the thresholds with oil anticorrosive, you can pour the oil from the engine, many people think that the oil is ineffective, I can assure you that this is not the case, the only problem is that the oil must be poured every 2-3 years since its protection period less factory equipment.

After you have changed both thresholds, you can begin to repair the bottom, but for this you need convenient access to it, and here tippers and a turner will come to our aid, there are quite a lot of designs on the Internet, one of the most reliable, simple ways to do it yourself or buy turntables as shown in the photo, they are easy to install and reliable, so that your car will stand firmly on its side during operation.

You can, of course, carry out work from a pit or under a machine, which, firstly, is unsafe and secondly, I always believe that the productivity and quality of work always depends on the comfort during its implementation.

Upon completion of replacing the thresholds, patching the bottom, coating with anti-corrosion agents, the most pleasant job remains - collecting all the parts that were dismantled from the car, assembly is done in the reverse order, this is no less painstaking work, but it returns the car to its proper appearance, which cannot but please the owner auto.

Preparing for replacement

For the entire VAZ family, thresholds are non-removable body elements; in 80% of cases, repairing an element involves completely cutting or cutting out the part. Overcooking requires preparation

1. The car is installed on a flat surface.
2. The negative terminal is removed from the battery. In some cases, the battery is removed.
3. The wiring from the inside of the doors from the electric windows is dismantled, all sensors are removed.
4. The seats are removed from the interior, the inner trim of the pillars and the floor covering are removed.
5. Doors are dismantled.

When planning to repair only the threshold, drivers have to partially change the bottom, install new jacks, and strengthen the central pillar. The metal for the body of the VAZ 2114, as well as for other models in the Lada Samara line, did not undergo anti-corrosion galvanizing.

Rolled steel was puttied, primed and painted. The inner part of the bottom and the box were not treated with anticorrosive; the first layers of rust appear on the internal parts of the body in the second year of operation. If the threshold is being repaired for the first time, and the “youngest” VAZ 2114 model is 6 years old, we can confidently say that the owner will find completely rotten metal under the bottom trim.

To prevent the geometry from becoming distorted during repairs and the central pillar from falling, it is recommended to install spacers or weld a channel.

Price issue

The cost of replacing rocker panels depends on the make and model of the vehicle, as well as the type of part that will be installed. If the threshold is replaced without painting and welding, then the price of this service will be much lower.

* – Sheet metal and welding works excluding painting and reinforcement work.
