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).

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.

Hello everyone, dear friends, and guests of my board magazine. Today I will tell you how I changed the thresholds and repaired related issues. So let's get started. To begin with, if everything is as sad for you as it is for me, before you start cutting everything out, don’t forget to weld a spacer so that nothing can escape. Yes, it may not be needed, but it certainly won’t be superfluous. Something like this:

Next, we begin to drill out the weld points (it’s better to immediately cut out the part with a grinder up to the central pillar and after, it will be easier to remove the whole thing, well, it will be clear later as we go along)

Here I decided to first prepare the internal threshold, clean it and prime it. Let it dry while I pick everything out. Be sure to remove the transport soil!

Domestic LADA cars are very popular in Russia. Unfortunately, the anti-corrosion treatment (or rather the lack thereof) of the bodies of these cars leaves much to be desired. Today we will talk about such a popular procedure as replacing thresholds on a VAZ-2110 car.

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.

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.

The main thing when replacing thresholds is accuracy and attention. It is very important to cut out all rusty and damaged metal from both the underbody and the sills. If even one small area of rust remains, the destruction of the structure will begin again. And, of course, anti-corrosion treatment when replacing thresholds is mandatory.

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.

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.

Use a grinder to cut through the previously marked areas.

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.

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.

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.

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.

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.

We clean the body of rust, putty and primer.

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.

We weld the connector to the bottom of the body.

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.
