Do-it-yourself replacement of thresholds on a VAZ-2110

Why do the thresholds of the VAZ 2110 rust?

There are several reasons:

Irregular anti-corrosion treatment. On vehicles of the VAZ family, preventive treatments must be carried out before each winter season of vehicle operation.
The car was damaged in the threshold area and poorly repaired. In this case, corrosion develops very quickly and after 2-3 years through holes may appear.
Winter operation on roads where a lot of reagents are used. Salts settle on the thresholds of the car and after a short period of time “break through” the external anti-corrosion treatment, starting the corrosion process. If you operate a car in such conditions, you need to wash it once a month and preferably with warm water.
Damage to the external protection of the threshold and its untimely restoration.
Blockage of drainage elements in thresholds. Drains should be checked once a year throughout the entire body.

The threshold consists of three parts:

External lining.
Amplifier inside.
Connector.

Thresholds can corrode in different ways, but generally, if there are through holes, you will need to purchase the entire three-piece threshold kit.

Threshold article number for the right side is 21100-5401060-00, for the left side 21100-5401061-00. Ask for connectors and amplifiers in stores; they are not available for order according to factory articles.

Description and purpose of VAZ 2106 thresholds

Some novice car enthusiasts believe that the thresholds on a VAZ 2106 or any other car play only a cosmetic role and act as tuning. This is not true - car thresholds are important, namely:

provide an attractive and beautiful appearance;
serve to protect the body from mechanical damage, as well as from the negative effects of chemical reagents and external natural factors;
provide ease of boarding and disembarking of passengers.

Thresholds perform a cosmetic and protective function

Load-bearing body element

If you look at the design of the VAZ 2106 thresholds, they consist of the following elements:

outer panel - is in plain sight and is called a threshold;
internal part - it can be seen from inside the car;
amplifier - located inside the box;
connector - visible if you look at the threshold from below.

A car threshold consists of several parts: an external and internal element, a connector and an amplifier

The rigidity of the car body is achieved by connecting the outer and inner parts of the threshold, the amplifier and the connector. Spot welding is used for this. The result is a box-shaped structure, which provides the necessary rigidity.

Jack sockets

The jack sockets are welded to the car body. If it is necessary to replace a wheel or other elements, you must raise the car. To do this, use a jack, which is inserted into a special hole on the jack socket.

The jack socket is used to install a jack and raise one side of the car.

To make it easier to install the jack in winter or slush, home craftsmen close the hole on the socket using a regular champagne cork. This way the nest always remains dry and clean. This not only allows you to quickly and easily insert the jack into it, but also extends the life of the entire jack socket.

Tools and materials for work

To repair VAZ 2110 thresholds you will need a lot of different tools. Below is a list of tools and materials without which high-quality threshold repairs cannot be made:

power tools (angle grinder, drill and accessories);
semi-automatic welding machine and accessories;
knife for chopping metal;
a set of keys;
ratchet crank;
hammer;
center punch;
marker for marking;
compressor;
body pliers;
spray gun;
gun for applying anti-corrosion agents;
epoxy primer;
degreaser;
putty;
sandpaper or red scotch-brite;
solvent;
polyurethane sealant for welds;
external anti-corrosion agent (for example, Body Autoflex or Teroson RB2000);
anticorrosive for internal cavities (Movil, Pushsalo and others oil-based).

Step-by-step replacement process

First, remove the doors, seats, bumper and front fenders. Also remove carpets, seat belts and sound insulation.
Protect your car windows. Sparks from grinders and welding can damage them. It is also advisable to cover the doorway with cardboard so that nothing gets into the interior.
Disconnect the negative terminal of the battery.
Place the vehicle on a pit or tipper.
Attach the new threshold and use a marker to mark the lines along which you will cut the old one.
Do not cut to size right away, give 5-6 mm of margin. You can always cut it to size in time.
Use a grinder to cut through the previously marked areas.
Be sure to wear glasses when working with an angle grinder.
We core all the contact welding points along the edges at the top and bottom of the threshold. Next, we drill out the points, and then use a body knife to separate the metals from each other.
After you have separated the threshold, remove it and evaluate the condition of the bottom, amplifiers and connectors. If necessary, cut off rotten parts of amplifiers, connectors, or remove them entirely.
Cut out the required pieces from the repair parts and weld them in place.
Prime all welds and repair inserts with epoxy primer, having previously “filled” the abrasive with a scratch to create conditions for good adhesion of the materials.
Cut the butt pieces to size and drill holes for welding along the edges at the top and bottom of the threshold.
It is better to make holes with a 7 mm drill at intervals of 3-5 cm.
“Stuff” the groove inside the threshold with abrasive and paint it with epoxy primer.
We bring the threshold and secure it with pliers or screws.
We make “pot holders” and gradually scald the threshold around it.
We clean all welds, grind the threshold with abrasive and apply epoxy primer.
We apply sealant to the non-facial welds, putty on the facial seams and paint. You can also apply an anti-corrosion agent, for example, Body Autoflex, before painting.
After all the work has been done, anticorrosive the hidden cavities with Movil or Pushsal.

The process of replacing thresholds for VAZ 2110, 2111, 2112 is clearly shown in this video:

The sequence of actions for replacing the threshold box

It is necessary to place the car on a level surface; a level garage floor, boards, etc. will do. This is very important, because when repairing rotten cars, the gaps of doors and other elements can slip away.
By marking the positions of the hinges on the pillars, you can remove the doors, as they interfere with the removal and installation of the threshold.
If the car is rotten and you are afraid that the body will “fold”, you need to fix the original position. This can be done by inserting guy wires into the door opening, guy wires from the projection of the rear sofa and in the A-pillar, placing a block about 1 m long and pressing it lightly with a jack. Thanks to these simple manipulations, you will keep the gaps of all doors in their old position.
Experienced people on my favorite body forum divided the replacement of thresholds into two options: correct and not quite correct. Proper repair involves replacing both fenders and sills. At worst, the threshold and the hams of the wings. This is necessary because the threshold is welded to the front pillar and to the rear arch far under the wings, and replacing the threshold without dismantling the wings remains problematic, if not impossible. But if everything is in more or less normal condition, then you can resort to the second method - welding the amplifier and butt welding the threshold trim.
Also, before sawing the threshold, it is necessary to inspect the condition of the inside of the threshold with the noise insulation removed; if it is rotten, then it is necessary to weld a curved piece of metal that needs to be used to connect the inside of the threshold with the floor panels.
After you have fixed the car body, you can begin to dismantle the old threshold. This can be done as you prefer, starting from the front or the back. It is better to brighten the weld spots, use a chisel less, because the edge is deformed, which is then quite difficult to straighten. For additional rigidity of the boxes, you can leave a strip from the old amplifier and lining in the area of the rubber seal, or one of them, this makes it easier to weld the new threshold and increases its rigidity.
The threshold consists of three parts - an amplifier, a connector, and a threshold cover. When replacing thresholds, the connector is often not a standard one, but is made from a suitable piece of tin a little wider than the standard one.
After dismantling the threshold, it is necessary to clean the edges from rust and old welding residues.
VERY IMPORTANT! Thresholds must be replaced as quickly as possible, within reasonable limits, of course. That is, you should not cut off the threshold and leave the car for 2-3 days, it may lose its geometry.
If the hinges of your doors are in order, but the upper corners of the doors touch the pillars, then this can be fixed. It is necessary, with the doors open, to use a jack and an extension to rest against the ledge of the rear sofa and the upper curtain of the door. Then grab this distance with a pipe from inside the rack. Try on the door if you need to add or remove. After welding the thresholds, the pipes can be cut off.
The new threshold is welded in the following sequence - amplifier-plate-connector. After cleaning all the surfaces that will be welded, you can begin welding the threshold amplifier. It must be cooked semi-automatically in a carbon dioxide environment through drilled holes with a diameter of 5-6mm. To make it easier to install the amplifier in the area of the B-pillar, provided that the old amplifier is more or less intact, you can leave a piece of the old one and weld the new amplifier to it. In the lower part, a threshold connector is also welded through drilled holes. The CONNECTOR is welded at this step only to the amplifier! It is welded to the floor last.
Attention! Trying on the threshold overlay is carried out only with the doors installed! Otherwise you might miss :)
After welding the threshold amplifier, it is necessary to clean the welding points and weld the trim through the drilled holes in the threshold trim. The pad is welded to the rack in several ways, depending on what is more convenient, the main thing is that the connection is strong.
Lastly, the connector is welded. There's a little trick here. The connector is welded to the floor panel; this can be done from a hole or through holes drilled in the floor panel. In order not to catch scale on your head, you can drill holes in the floor and, pressing the connector from below with a jack, weld it through the holes.

Let's summarize

To replace VAZ 2110 thresholds with your own hands, you need to have many specific tools and skills. If you are not ready to learn bodywork and invest money in tools, trust the replacement of the threshold to professionals. The price of replacing a threshold with painting and anti-corrosion treatment is from 7,000 to 12,000 rubles.

The four-door front-wheel drive sedan VAZ 2110 was produced for 13 years. AvtoVAZ stopped producing the model in 2005. Thanks to the large number of components, it is easy for drivers to maintain and repair the body and chassis.

The price of thresholds for the VAZ 2110 from official dealers starts from 1,700 rubles. per set. Tuning body kit parts cost up to 6,000 rubles.

Design features: description

Today on a car you can find two design options for thresholds: removable and non-removable. The factory equipment of 2110 involves the installation of non-removable parts that fit into the side of the body and provide the necessary structural rigidity. For a permanent threshold, rolled or black steel with a thickness of at least 0.9 mm is used.

The part is welded to the bottom, preventing the central part of the car from twisting during a frontal impact. This is also an element of passive safety.

Removable sills protect the underbody of the car from mechanical damage, prevent the rapid spread of corrosion and improve the overall appearance of the car. They are installed from inside the cabin, attached to the bottom with self-tapping screws. Rolled iron is used in production and the part is chrome plated.

To further protect both removable and non-removable parts, plastic door sills, steel moldings, aluminum fairings, and body kits are used. Structurally, the non-removable element is a box welded from several elements:

Amplifier. The part is spot welded to the sidewall and bears the main force load from vibrations.
Connector. The lower part of the threshold. May consist of one continuous or several parts.
External part. It is located directly under the door and is painted at the final stage of repair.
Inner part. Visible from inside the car after installation.

Official VAZ dealers offer original repair kits for body repairs. The parts correspond to the dimensions and are suitable for the thickness of the metal. But, like factory elements, they do not undergo the galvanizing process. After reinstallation, all parts must be carefully treated with anti-corrosion compounds, in some cases, if the element is changed, partially puttied.

Threshold decoration

In order to make the appearance of their car more attractive, many owners install special plastic trims and moldings on the sills.

Door sills

Threshold covers for the VAZ 2106 are plastic elements that are attached to the outer part of the threshold. The main advantages of installing decorative overlays:

protection of thresholds from the negative effects of moisture, sand and dirt;
prevention of premature corrosion;
protection of paintwork from mechanical damage;
the ability to hide minor defects;
improving the appearance of the car.

Plastic door sills improve the appearance of the car

Moldings

Threshold moldings are rubber-plastic products that are attached to the standard places of the VAZ 2106. They are mounted with double-sided tape. The presence of hollow sections inside allows you to absorb minor mechanical shocks. Such elements also decorate the appearance of the car.

Threshold moldings can be chrome or black

Features of repair of VAZ 2110 thresholds

Before repair, a complete diagnosis of the bottom is necessary. On the overpass, the metal of the bottom is tapped, and the quality of the jacks is checked using a screwdriver or an awl. Replacing the VAZ 2110 thresholds has some features; it is carried out either at a service station or independently. Rules for self-repair:

The car is installed on a flat surface at a height, which is convenient: you don’t have to bend down to the ground during welding and cutting.
Before welding the upper part of the permanent threshold, it is recommended to hang the dismantled doors in place. In 30% of cases, independent welding of parts leads to a slight distortion of the body geometry, which cannot be determined with the naked eye. As a result, this will lead to the doors closing with difficulty or not closing at all.
The internal element is treated with anticorrosive. It is recommended to use an oil or paraffin composition for interior work in the cabin and bitumen mastic for external metal processing.
A rotten threshold must be completely replaced. If you need to get rid of rust, a solvent is used. After cleaning the element with a grinder, it is necessary to treat the surface with a composition that removes rust. All work is carried out wearing gloves and safety glasses.

Important points

All work on replacing thresholds should be carried out with the machine installed on a level surface, without distortions.
Before welding the top edge of the new thresholds, you should definitely try hanging the doors on the car yourself. There are often cases when doors after welding either close with difficulty or do not close at all. And this can happen due to one slight misalignment of the thresholds, which is not always possible to notice with the naked eye.
You should never skimp on anti-corrosion treatment of thresholds. If it is not carried out, all the work done will go down the drain in a few years.
It is best to clean thresholds from rust and dirt using a solvent. When working with it, you need to follow safety rules: use gloves, wear safety glasses (this is especially important if you have to work on the bottom of the car while standing under an overpass - drops of solvent can easily get into your eyes), and apply the solvent itself only with a paint brush.
Before welding the thresholds, a series of holes with a diameter of at least 3 mm should be drilled in the areas of metal to which the threshold is planned to be attached. This will greatly facilitate the spot welding process, and the threshold will be held more firmly.

DIY replacement: step-by-step instructions

A complete replacement of the thresholds is carried out if the part has corrosion wear of more than 50%, there are holes, or the rust has reached the amplifier. Partial overcooking is carried out after a mechanical shock, if there is significant deformation and in cases of a single corrosion plaque. A patch is welded onto the threshold. To replace, you will need the following tools:

angle grinder (grinder);
wide chisel, set of screwdrivers;
electric drill with a set of drills;
clamps and latches will be needed for installation before welding;
gas welding or electric semi-automatic;
automotive primer;
bitumen mastic;
iron brush, R-80 sandpaper.

Before welding the part, it is necessary to dismantle the interior and doors. Preliminary work step by step:

The car is draining fuel.
The negative terminal from the battery is disconnected; in some cases, the battery is removed completely.
The doors are being dismantled.
The trim of the pillars is removed from the interior, the carpet can be rolled to the side and covered with a rag.
The overhead protective threshold, if any, is dismantled.

It is recommended to remove all plastic trim to avoid ignition due to sparks from the welding machine. The dashboard is covered with rags, the glass can be covered with paper so that dust from the grinding machine does not settle on them. Instructions for overwelding parts of a fixed threshold:

Mark the cutting lines of the old element with a marker.
Using a drill, along the marked line, drill holes with a diameter of 0.4 mm at a distance of 8–10 cm from one another. If a standard unit is changed, the factory spot welding areas are drilled out.
Use a grinder to cut out the old element exactly along the marking line. You can use a wide, sharp chisel. Drilled holes make cutting process easier.
Cutting or cutting takes place in the following directions: in the area of the front door, rear door, and the last section to be cut is in the area of the central pillar. The quality of the lower edge of the rack amplifier is checked: if the part is rusty, it is replaced or a power patch is welded.
If the metal of the rack amplifier is in order, the outer panel is partially cut off. In the area of the stand and wings, it is necessary to leave 5 cm of old metal, to which the new outer part will be welded.
Check the amplifier: in 70% of cases the part must be replaced. Remove the steel panel. The cut should pass through the welding point of the amplifier.
Clean the seat from dirt and rust with a grinder. Cut out rusty areas completely, sand them down to white metal, and treat them with a solvent or rust converter.
Weld the threshold connector to the subframe reinforcement with an overlap and align the lower edge.
Fit the outer part to the connector and secure with clamps.
Weld the connector to the bottom of the body, do not loosen the clamps.
Weld the outer part.
Clean the weld seams with a grinder and sand them.
Apply a layer of automotive putty, prime the surface after drying, and paint at the final stage.

Replacing thresholds is a rather labor-intensive and labor-intensive process. At the service station, repairs are carried out by two experienced craftsmen. When replacing yourself, special attention must be paid to the fit of the new element and check the installation locations of the jack.

Tools you will need for DIY repairs

In order to save several thousand rubles, the car owner will need the following set of tools:

Bulgarian.
Electric drill with a set of attachments for stripping.
Cleaning discs for grinders.
Standard set of automotive tools.
Semi-automatic welding machine and a couple of spools of wire.
The new thresholds themselves, if they are planned to be replaced. It is strongly recommended to change the entire threshold at once, as this will help avoid problems in this place for 2-3 years;
Primer, solvent, paint, putty and other materials that will be needed to process welds and paint new thresholds.

To carry out threshold repairs, you need a spacious garage with ventilation. This is especially true when carrying out painting work.

If the garage does not have good ventilation, then it is better to paint the car outside.

Preparation for repair

If there are holes in the threshold, it must be completely replaced.

Before you begin repairs, you need to carefully inspect the car's sills. It may be possible to get by with cosmetic repairs . For inspection, the car must be driven onto an overpass or pit.

If, in the case of local corrosion or damage to one section of the threshold, it is a spot repair, then if there are several holes, it is better to replace the entire threshold.

The process of removing the old threshold

It is recommended to dismantle the thresholds after removing the doors, seats and fenders of the car.

It is also recommended to remove the wheels. In practice, only a few do this. Most often, independent repairs occur without removing other body elements. Those elements that may be damaged during welding or painting are simply covered with suitable material.

Before dismantling the sills, the fenders, seats and doors must be removed.

The replacement process itself occurs as follows:

First you need to disconnect the battery.
Next, using a grinder, the old threshold is cut out, or the damaged part of the threshold is removed.
Using a grinder, we cut out the old threshold.
After the threshold is removed, the body must be thoroughly cleaned of rust.
Those places where welding will take place also need to be cleaned of rust, putty and primer.
We clean the body of rust, putty and primer.

We recommend: The windshield washer does not work: we look for the cause and eliminate it

Only careful preparation of the base for welding will help to avoid welding seams in the future.

Installing a new part

Before installing a new threshold, you need to weld the connector of the new threshold to the subframe amplifier.

We weld a new connector to the subframe reinforcement.

Welding should begin from the center of the part , gradually moving towards the edges. After the connector is welded, you need to clean all weld points. The further installation process is as follows:

The front panel of the new threshold is adjusted to the vehicle.
We adjust the outer panel to the connector.
After the front part, the entire threshold is adjusted. Clamps are used for fixation.
The welding area must be cleared of paint and primer.
Holes are drilled at the bottom of the threshold panel.
Next, the outer part of the threshold is hung on the car, after which it is secured with self-tapping screws.
The lower part of the panel is welded through the holes made.
The connector is welded to the bottom of the body.
We weld the connector to the bottom of the body.
The metal must be carefully welded on top of the threshold.
After this, the welding seams are cleaned and processed.

Next, the entire surface of the threshold is prepared for painting. Primer and putty are applied. After stripping the putty, several layers of paint are applied. If necessary, apply clear varnish.

The result of replacing the threshold.

Do-it-yourself painting of VAZ 2110 thresholds

The standard repair kit from official dealers is designed for subsequent painting of the part and is supplied in shipping primer, which must be cleaned off before welding. After replacing the threshold, when the primer layer has dried, it is painted:

Sand the surface with high and low abrasive sandpaper.
Paint the body using a spray gun or spray gun. It is necessary to apply two layers of auto enamel. The sprayer is kept at a distance of 25–30 cm from the surface.
Apply the first layer of auto enamel, wait for the paint to dry for 7-10 minutes.
Apply a second coat of paint.
After complete drying, apply protective varnish.

Average prices for work on replacing thresholds on a VAZ 2110

Specialized services carry out a complete replacement of threshold 2110 with painting in 2 days, the cost of work starts from 15,000 rubles, the customer’s repair kit is used. The work includes:

checking the bottom, side members, jacks;
complete dismantling of the interior;
dismantling wings, front trim, doors;
cutting out waste elements;
installation of new ones using high-precision welding;
complete anti-corrosion treatment;
painting;
installation of overlays, at the request of the customer.

It is recommended to additionally protect the parts with plastic or metal fairings: this will increase the service life of the main part. The cost of the cover starts from 150 rubles; you can install the fairing yourself in 30 minutes.

Iron

Original parts are produced by the AvtoVAZ workshop; the thresholds are made of rolled steel and covered with transport primer. Spare parts are installed in their original place. The metal does not undergo additional galvanization; after repair, anti-corrosion treatment is required.

The set includes a perforated amplifier. Cost 2500 rub.

For self-repairs, profiles are used instead of a threshold. The pipe is installed in place of the original part and is attached to the bottom with cross members. It is distinguished by increased corrosion resistance due to the metal thickness of 1.5 mm and an additional layer of zinc.

Plastic

Plastic thresholds for the VAZ 2110 are produced by several licensed manufacturers. The most famous and popular:

RS Tolyatti. The cost of the plastic kit is 1600 rubles. When replacing, a steel reinforcement is required, which is not included in the kit. Parts are made from impact-resistant, lightweight ABS plastic, element thickness 3 mm. The parts are installed on the load threshold or base using self-tapping screws or auto glue, are not painted, and are easily adjusted to body dimensions.
LLC M-version. The company produces tuning sills and body kits for the VAZ 2110/12 line. Parts are made of carbon fiber, can withstand loads of up to 300 kg, and are resistant to chips. The elements must be painted after installation, the cost is 4,700 rubles, the amplifier is not included in the kit.

What affects the cost

The location of the repair is a major factor in the cost of replacement. If you carry out repairs yourself, drivers only spend money on purchasing the necessary material and parts. Tools are often either rented or already present in the garage.

When repairing at a service station, the work is expensive, and this is justified. The design of the threshold, despite its simplicity, requires great skill and care when replacing. If you are not confident in your skills as a welder, straightener and tinsmith, it is better to entrust the replacement of thresholds to a specialist.

Step-by-step instructions for replacing thresholds on a VAZ 2110 Link to main publication

By looking at the condition of the underbody of the car, as well as assessing how rotten the sills of the VAZ 2110 are, you can easily determine how old the car is. Unfortunately, the body of the tenth generation VAZ without proper care can turn into dust with through holes after 8-10 years. The car takes on an extremely expressionless and careless appearance.

Preparing to replace the threshold

You need to lift the car and level it. It is better that the body is supported evenly at several points to avoid body distortion.
When completely replacing the threshold, it is better to remove the doors. This will give good access and prevent damage to the doors during welding. When removing doors, it is better to leave the hinges on the body so that their position does not change. In most cases, it is also necessary to remove the front fender. Removing the front fender may require additional disassembly. So, for example, you will have to remove the front bumper and headlight.
If the threshold is being replaced due to its corrosion, then it is necessary to clean the area around the rusty areas with a reserve in order to determine the boundaries of the rust. This way you can understand which areas of the threshold can be left and which need to be cut out.
To replace the thresholds, it is necessary to dismantle some interior parts, such as plastic cladding, seats, and rubber seals. Carpeting can be rolled up.
Protect your car's paintwork, glass and interior from sparks from welding and grinders.
Before welding, you need to disconnect and insulate the battery terminals.

Reasons for replacing thresholds on the VAZ 2110

The bottom and sills of the VAZ 2110 are susceptible to corrosion, as a result of which they rust and collapse. Mainly due to the fact that it is this part of the car that is most exposed to moisture and other aggressive environmental factors, such as reagents and salt, which are sprinkled on roads during icy conditions. Mechanical damage cannot be ruled out : impacts and scratches first lead to dents and chips of paint on the thresholds, and then rust occurs. The quality of the metal itself plays an important role. In these cases, the need to change the thresholds becomes obvious. The work of replacing thresholds involves the use of both welding and abrasive tools. Carrying out painting, puttying and other work. In other words, this is an enterprise that should last at least several days with fairly good labor productivity.

The easiest way to work is with a semi-automatic welding machine, with which anyone can learn how to weld. If you don’t have it, then you probably shouldn’t run to the store. You can always contact your friends or a specialized workshop.

After all, the unit costs approximately more than 15 thousand rubles. For a full repair of a VAZ 2110 at a service station, you will be asked for approximately 3 thousand.

rubles And it will last for ten years. But if you decide to do the repair yourself, then these instructions will help you.

Features of repair and replacement of thresholds at service stations

VAZ-2110 owners most often repair the sills of their cars with their own hands. Based on the cost of the car, repairing thresholds at a service station is impractical.

For those owners who are thinking about repairs at the station, we can give approximate prices for these services :

Removing the threshold – from 500 rubles.
Installation of a new threshold – from 6,000 rubles.
Painting the threshold - from 1,000 rubles.
Materials – depending on quality, from 900 rubles.
Threshold repair, which consists of welding holes - from 1,000 rubles.

Replacing thresholds at a service station is quite an expensive procedure.

In total, it turns out that repairing or replacing the threshold will cost from 6 to 9,000 rubles . This amount will most likely have to be multiplied by two, since thresholds are usually changed on both sides. The total is 1 2 –18,000 rubles . Given the price of a VAZ car in the amount of 60–90,000 rubles, carrying out this procedure at a service station is very expensive.

Most owners of domestic cars prefer to carry out repairs themselves, which helps to significantly save money.

How to change the thresholds of a VAZ 2110

To avoid distortion of the car body, place the car on a flat surface.
Remove the locker, doors (rear and front), driver and passenger seats, car fenders. Also remove seat belts, floor mats, and sound insulation from the floor.
Protect your car windows with homemade curtains, which can be made from cardboard. This will be needed to prevent them from being damaged by sparks flying from the grinder. Otherwise, black spots will appear on the windows that cannot be removed.
Remove fusible and plastic machine components from the work area.
Disconnect the battery to prevent it from being affected by the welding machine.
Mark the cut lines for the old thresholds. A series of holes with a diameter of at least 4 mm are drilled along these lines , located at a distance of 5-8 cm from each other.
Using a grinder, cut off the old threshold, part of the bottom damaged by corrosion, as well as the threshold connector at the bottom and top of the VAZ threshold.
When cutting off the outer sill panel, be sure to leave areas of metal at the front and rear fenders. The length of these sections is at least 5 cm; it is to them that the new panel will be welded later. You should also leave a small area of metal under the B-pillar.
Continue the repair by scraping the surface where the new threshold will be located using a scrubbing brush, and then treat the surface with a corrosion neutralizer .
Before carrying out welding work at the stage of installing a new part, first hang the doors to ensure correct installation.
After installing the component on the car, be sure to treat the surface with an anti-corrosive agent or special primer.

It must be remembered: the larger the area of the damaged areas, the more material and effort will be required to repair them. From the tool we need:

welding unit (the most convenient and simplest option would be semi-automatic welding);
grinder and 3 discs for the grinder, a hard metal brush for the grinder;
a set of new thresholds, amplifiers and connectors for the VAZ 2110;
grinding tool;
electric drill;
metalworking tools;
packaging of automotive mastic;
2 medium-sized paint brushes;
can of primer;
bottle of solvent.
