How to replace thresholds on a VAZ 2110 in your garage

Costs for replacing VAZ 2110 thresholds

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, as you understand, it will last for ten years. Let's estimate how much all the necessary materials cost to carry out the repairs yourself.

From the tool you will need:

welding unit (the most convenient and simplest option would be semi-automatic welding);
Bulgarian;
grinding tool;
electric drill;
locksmith tool.

By the way, we do not specifically indicate the prices for the tool, since buying it solely to repair the thresholds of a VAZ 2110 is truly pointless. Now let's similarly determine the necessary materials:

carriage for an angle grinder, about 300 rubles;
several cutting discs for the grinder, because you will have to cut a lot of metal (about 300 rubles);
cleaning wheels, we also buy several pieces and give 150 rubles;
thresholds for the right and left parts of the car with amplifiers. Only 2000 rubles.
associated costs (for example, a VAZ repair kit for a rotten bottom or rear wing), approximately 1000 rubles;
jar of mastic, 200 rubles;
soil, 200 rubles;
other expenses for small materials and spare parts (brushes, solvent, drills, etc.), 300 rubles.

Having carried out a simple calculation, let's determine the material benefits of self-repair. Let's put aside the cost of the sills, wings and bottom. It turns out that you, one way or another, spend about 1,500 rubles on materials. Thus, the savings, taking into account the cost of repairing VAZ 2110 thresholds at a service station, will be about 1,500 rubles. In terms of time costs - several days (at least two or even three).

Feeding

In nature, aquatic inhabitants eat larvae, phytoplankton, and insects.
In the aquarium, they can be fed with any dry food. But for a bright and rich color, experts recommend feeding them with bloodworms, tubifex, and daphnia. When choosing food, it is worth considering that the fish’s mouth is small and it will not be able to swallow too much food. The following foods should be present in the rasbora diet:

small insect larvae or chopped bloodworms;
vegetable flakes, ground to a powder;
artificial dry food that needs to be finely crushed;
zooplankton.

Feed the fish twice a day in small portions.

Attention: with an incorrect diet, the rasbora begins to lose its bright color and various diseases appear.

Repair technology

When changing the thresholds on VAZ 2110 cars, thorough preparatory work must be carried out. You can't just pick it up and start replacing it. The technology requires dismantling the front and rear doors, locker; it is also necessary to remove the front passenger and driver's seats, and front fenders. The rear wheels and seat belts are also folded to the side, and the floor mats and sound insulation are removed.

Preparatory work alone can only take, with a fairly clear organization of work, about noon at best. The front and rear windshields of the VAZ 2110 should be reliably protected with cardboard curtains - since sparks flying from the cutting wheels of the grinder will inevitably leave indelible black spots on them, and you probably don’t want that at all. All other plastic and fusible materials must also be removed from the work area.

After which the time comes for the “operation” to save the VAZ. Beforehand, do not forget to completely disconnect the battery in order to prevent it from being affected by the potential of the welding machine. Now you need to pick up a grinder and cut a lot, a lot, removing the old VAZ 2110 sills, parts of the rotten bottom and the lower connector. The same fate awaits the upper connector in places where it has been eaten away by corrosion.

Afterwards the surface is thoroughly cleaned using a brush. Before installing new VAZ 2110 thresholds, we treat the metal with a rust neutralizer (converter) in order to prevent intense corrosion in the future. By the way, by default, the tens body technology does not provide a threshold amplifier. It is advisable to install it.

Then everything should go along the well-trodden path. The connectors are installed, then it’s the amplifier’s turn, and then the threshold itself is welded. The car may not yet look as kosher as we would like, but a good part of the main front of work on replacing the VAZ 2110 thresholds has already been completed.

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.

The final stage of work. Finishing and painting

After completing the welding work, all that remains is to process the seams with a cleaning disk and roll the lower part of the VAZ 2110 threshold (clamp it onto the connector). You can take a few breaths, then it will be easier. From the outside, treat the car with a primer. Inside the cabin, the bottom is initially treated with mastic, then a layer of polyethylene is laid down, then back with mastic, sound insulation and carpet.

All that remains is to collect all the other parts in their places and you can hit the road again. Be prepared that the total scope of work may take at least three to four days. As you understand, having certain skills and tools will allow you to save a considerable amount of money, but it also takes a lot of time, so it’s up to you to decide whether it’s advisable to restore the VAZ 2110 thresholds yourself.

How to determine the scale of restoration work on thresholds

So:

Before you find out whether the thresholds on a VAZ 2110 need to be replaced or whether it is enough to carry out cosmetic repairs to the body in the form of straightening or painting, the car must be installed on an overpass or raised on a lift.
Then they quickly inspect the places of corrosion, dents, where the paint is peeling off, which flakes off until it reaches a strong adhesion to the car body.
The areas that need to be replaced and where there are still “live” parts are determined. Replacing the threshold in a VAZ 2110 also means additional costs for painting work. Sometimes it is enough to replace only a small section of the threshold and the VAZ 2110 will look like new, and the car body will serve for many more years. This option is possible if the threshold receives a mechanical shock, when the paintwork is damaged and rust occurs. In this case, it is 15 centimeters longer than the corrosion area, there must be a new threshold along the direction of the car, and 30 centimeters longer in the direction of the trunk.

Replacement of thresholds of a VAZ 2110 car

First of all, it is necessary to clearly determine the size of the areas to be restored. If the excess is cut off, then patches will need to be welded onto the uncovered areas, but this is unsightly, and sometimes it will not allow you to close the door.

Worn section of the threshold

The threshold consists of three main parts: the outer panel, the connector and the amplifier. They are connected to each other by spot welding. The instructions suggest the following procedure on how to replace the thresholds on a VAZ 2110:

The front and rear doors are removed.
The aluminum threshold located under the door seals and the lower part of the door seals are removed, and the mats are partially raised for ease of work.
Rotten thresholds are removed. Initially, the area located near the front door is dismantled, then near the rear and lastly in the area of the B pillar.
Old thresholds are removed using fine drilling or a grinder. In the first case, the locations of spot welding are marked, then these areas are carefully drilled.
If you are completely replacing the threshold of a VAZ 2110 with your own hands, then the holes are drilled in the rear, on the side where the reinforcement for installing the jack is located, and in the front where the old connector will be stored.
When dismantling the outer panel, it is necessary to leave small areas on the side of the front and rear wings, approximately 50 millimeters of the old panel, to which the new outer part of the panel will be butt welded.
On the front side of the wing, you need to leave a small part of the connector.
The threshold amplifier is removed.

After removing the old threshold, the remaining metal is cleaned of rust, if necessary, the amplifier is adjusted to install the jack, rotten areas on the bottom of the body are cut out, and the places where welding will be performed are cleaned of rust and old paint.
Replacing the threshold on a VAZ 2110 starts with the connector. At the rear it must be placed overlapped on the subframe reinforcement; at the front it must be placed end-to-end with the old section of the connector.
The purlin is welded.
The amplifier is shortened, a cutout is made on it, which is located in the area where the rack is located, otherwise, during installation, the old piece of the amplifier left behind will interfere with it.
The edge of the lower amplifier and connector is aligned.
The lower part of the amplifier is welded to the connector, starting from the middle to the edges.
Weld points are cleaned.
The outer threshold panel is pre-adjusted as accurately as possible.
Final adjustment of the threshold dimensions on site. You need to start from the top, leaving minimal gaps.
The welding areas are cleared of soil intended for transporting the part.
Holes for welding are drilled in the lower part of the outer panel.
The outer panel is hung and secured at the top with screws or clamps, as shown in the photo.

Hanging outer panel

Through previously drilled holes, the lower part of the panel is welded to the amplifier, and a connector is welded to the bottom of the body.
Metal is welded at the top of the threshold.
The patches are welded on the bottom side.
Welded seams are cleaned, puttied, checked for leaks, and painted.

About decorative thresholds VAZ 2110 (overlays)

After you install new metal sills on your updated VAZ 2110, you may want to go even further, thanks to plastic sill covers, creating a stylish aerodynamic tuning. Of course, it will only have a decorative role, but such a fashionable solution often looks very impressive on the VAZ 2110. By the way, the plastic sills from Priora are also excellent in the top ten.

It’s worth mentioning right away that the use of plastic overlays, although intended not least to protect the VAZ 2110 sills from the effects of road dirt and splashes flying from under the wheels, can equally have the opposite effect. At the same time, your stylish body kit may turn out to be the main catalyst for corrosion. Now let's explain how this happens.

Lada Priora thresholds

The thing is that dirt and road moisture penetrate into the space between the plastic of the trim and the threshold of the VAZ 2110, which should be cleaned out regularly. If this is not done, the humid environment becomes the main catalyst for metal oxidation and the car body becomes unusable ahead of time. A similar situation occurs as holes form in the thresholds themselves: dirt and moisture penetrate inside and corrosion continues from the inside.

But this does not mean at all that it is better to simply abandon thresholds. VAZ 2110 cars are supplied with them from the factory. They are also an important part of external auto tuning and additional protection for the thresholds of the VAZ 2110. All you need is to promptly monitor the appearance of dirt under the plastic covers and get rid of it.

By the way, the original plastic linings of the VAZ 2110 come in two types: old and new. Previously produced thresholds were made of lower quality and thin plastic, and were attached to pistons. On cars released later, the linings fit more firmly to the body and are fastened with self-tapping screws. A full-fledged stylish body kit for the VAZ 2110 will cost the owner approximately 3-5 thousand rubles.

Some useful tips

To keep the thresholds of the VAZ 2110 in good condition, it is enough to regularly monitor them. If you do not allow rust to eat through the holes, the sills can last a really long time even with extremely intense driving on dirty and wet roads. There are special products on sale that prevent the spread of rust.

In this case, after washing the car, it will be enough to clean the affected area of rust and treat it with a neutralizer. By the way, these tips are suitable not only for servicing the thresholds of the VAZ-2110, but also for the entire car as a whole. The doors, bottom and wheel arches are processed in a similar way, but this is material for a separate article.

This is where our article comes to its logical end. We sincerely hope that you found it useful. Don’t forget to monitor the condition of the sills on your VAZ 2110 and let rust never bother you.

How to determine the degree of damage to thresholds

Before deciding whether you really need to replace the thresholds or whether you can get by with cosmetic repairs of the car, you must:

Raise the car using a lift or place it on an overpass.
After this, a visual inspection of the damaged areas is carried out, namely, where corrosion began to appear. The paint in these places peels off exactly until it reaches the point where it adheres to the car body.
You should be prepared for the fact that replacing thresholds will entail additional costs required for painting work.
It is not always necessary to make a complete replacement; sometimes it is enough to do this with just a small damaged area, and your car will serve faithfully for a single year.

As a rule, minor damage occurs when the threshold receives impacts from any foreign objects, as a result of which peeling of the paintwork begins and, accordingly, the further appearance of rust.
