In detail: do-it-yourself repair of gazelle thresholds from a real master for the site my.housecope.com.
Freight and cargo-passenger "Gazelles" are intensively operated in a wide variety of road and climatic conditions. Therefore, this "workhorse" requires not only maintenance of the engine and transmission, but also the repair of some body parts. Watch a video on replacing thresholds on a Gazelle.
Aggressive external environment and sometimes unimportant quality of bodywork lead to the fact that the thresholds begin to rust and eventually become completely unusable.
Replacing thresholds on a Gazelle car is as follows:
- A set of new parts is purchased. It is quite expensive, so you need to choose the thresholds carefully.
- Old thresholds are carefully cut out with a grinder, the installation site is cleaned with it.
- In order for the thresholds to come in, you need to process the edges in the sinuses.
- The purchased parts are adjusted on site and installed. Make sure that there are no various inconsistencies and distortions.
- The joints are welded neatly.
- After the threshold is securely stuck and in place, the joints are removed. When working with a grinder, special care is needed so as not to damage the newly installed part. Be careful when performing work. To be confident in your actions - watch the video on how to replace the Gazelle thresholds.
Threshold handling is a separate issue. Now there are a lot of different car cosmetics on the market. Most often, new body parts are treated with "Movil". But this will only help in the case of new thresholds. If rust appears during operation, then it will no longer help; other means and more thorough study are needed.
Pay attention to what the welding is being done. Different types of welding machines and electrodes can produce different effects, sometimes the opposite of what you expected. Semi-automatic machines are often used. Some devices can simply burn through the part, so before proceeding with the replacement, consult with specialists.

Gentlemen! Tell me please! who changed the thresholds on their own? where to start? the thresholds are rotten. winter is coming ... it's cold. If I go to the service, I'll lose my job. They are ready to do it in only 10 days. And they give me only 2 days off per week.
Well, the repairers always had a queue. So just sign up and send the car in for repair. If you don't have any skills, you just screw up!

To begin with, you need a semiautomatic device, a place where you will not be pulled by your legs, a drill, a grinder, a couple of clamps. In principle, not anything complicated, if not glamor. In a couple of days, one side can be made without painting.

You sit on the site in the evening, it will appear dyoma, you ask him questions. He changed all the metal in a circle on his own.

I completely agree. You yourself get lost for a longer time without the skill and you won’t do it efficiently.

As I understand it, the machine is not yours. Do not worry. Buy pliers for rivets and rivets themselves. A drill, a grinder, drills and forward and with a song. If you do it competently, it will hold no worse than welding. Good luck to you dear.

there is only one way out of this situation, (in 2 days you will EXACTLY not have time) you cut off the threshold, a step (on one side start) at the same time such a thing as holes in the floor will pop up. In my version, it turned out that I had to cook the floor and weld on the edge with a margin, because there was nothing new to weld on, so think for yourself what is better for you? But you can slowly disassemble one side and do it without giving up work (well, you will ride with a hole on the footboard for a while), then another one.

Do you know what is the most vulnerable point of many truck models? Yes, exactly the rapids. Most often, they, dear ones, become unusable and require a complete replacement. Find out how to replace this important gazelle body part with a minimum of time and effort. Is it possible to make such a repair at home?
Prevention increases the life of the vehicle
It is only in the films that the driver sat down, started the car and drove off. In real life, not everything is so simple. Before getting behind the wheel of a car, the driver must inspect the car, check the level of oil, coolant and brake fluid, the operation of the brake system, the handbrake, the pressure in the wheels, and see if there is a leak.
After all, it is easier to prevent a breakdown than to be nervous, figuring out how to drag the car to the garage or car service and how, by whose power to fix it.
Some still put their lives at risk, fearing that, like this “gazelle” in the photo, the car would not be broken into two parts on the road.
Daily routine check-ups for many drivers have become a habit, like brushing their teeth in the morning, and only takes a few minutes. What does it do?
First of all, safety on the road. And, as you know, a timely detected malfunction is much cheaper than body repair with replacement of parts and body parts, and with regular preventive maintenance, the service life of the car doubles.
Most often, we solve the problems that have arisen after the fact, we will learn how to remove scratches and align the roof of the car ourselves, what kind of protection of the bottom from corrosion is necessary, but it would be easier not to bring the car to major repairs.
How often do you need to carry out preventive inspections of trucks?
Daily - every day before departure and at the end of the day after the trip.
Periodic - after ten thousand kilometers or after six thousand if the truck was operated on bad roads.
Body repair of thresholds on the example of "gazelle"
“Gazelka” on our roads is a workhorse that can deliver cargo to any place, even off-road. And these circumstances: rains, mud, deep rut, freezing of the body in winter, lead to rust and destruction of metal.
The most vulnerable point is the rapids. If the car is operated by its owner, then he still treats his breadwinner with care. And when the car is rented and the driver is trying to squeeze as much out of it as possible, to make money, then there is no need to talk about careful prevention - the car is often not washed, the bottom is not processed.
Such a "gazelle" gets to body repair in a deplorable state, one might say, with almost rotten sills. Let's consider how to fix the situation.
It should be noted right away that when rust has eaten more than 60% of the metal on the thresholds, they must be changed. You can do this with your own hands in an ordinary garage.
Stages of replacing the gazelle thresholds
Before you carry out body repairs, carefully inspect the thresholds, if there is no possibility of repairing without replacing these body parts, go to a car dealership, better specialized, for a repair insert.
Thoroughly clean the thresholds from dirt and rust, dry, determine the place that needs to be removed.
Attach the repair insert, carefully trace around with chalk so that you do not cut off anything unnecessary later.
Start cutting one centimeter below the line. If you cut along the line or higher, then the insert will be smaller, it will start to fall through, and you will not be able to weld it. When doing this kind of body repair, these nuances will help you get it right.
Take a hem bend, trim the edges, clean to keep it even and free from rust, try on the insert, secure, you may need to adjust it.
Now, on the insert, you need to punch holes with a hole punch through which you will weld it, the density is two centimeters. Screw the part with self-tapping screws. In fact, there is even a video that captures body repair - the moment of welding and replacement of thresholds.
Begin to weld the insert, and you need to cook over the resulting holes overlap up to three millimeters. If you try to cook with a continuous seam, this place of the body will lead. Cook pointwise, but first through one hole, each time cooling the point, then weld on the missing places - this way is stronger and more reliable.
Do not forget to use a protective mask for welding so as not to burn your face and catch bunnies, that is, not to damage your eyes.
Once the weld is finished, begin to clean the weld. The inner one must be primed and passed through with a special joint sealant. The outer one should first be putty, then primed for painting. How we prepare the car for painting, you can refresh your memory.
Pick the right shade of paint and finish off by painting the thresholds. Now they will serve you for several more years, given that they did everything for themselves and conscientiously.
Should you perform body repairs with the replacement of thresholds yourself? Definitely yes. Let's just say: if you want to save time, because there is no guarantee of quick repairs in a car workshop, and money - you can buy repair inserts for the cost of repairs, then do-it-yourself repairs will be very beneficial to you.
The price of the proposed repair kit for body parts is from 11 thousand rubles and more and depends on the seller.
Before ordering, we defect areas bodyto be replaced by repair parts and spare parts.
We order and buy body auto parts, we carry out the repair ourselves or in the service.
Repair video
The repair procedure is as follows:
- we mark places on the body for cutting, applying the appropriate auto parts from the kit, and then we cut them out in an accessible way (cutting, cutting). The most suitable and safest way is an abrasive machine. At the same time, fire safety during work is maximum, which is important when carrying out repairs in the garage.
Your car has temporarily become even more unsightly with its black sinuses in the body. We process the edges of the sinuses, leveling them with an available tool with a chamfer for subsequent welding. You can even process it with a broom file, but better with an abrasive machine. This is both better and faster.
We proceed to the second stage of work:
- installation and tacking of new body parts from the purchased kit. This work must be done especially carefully - without distortions and in place.
Then we weld the joints.For this, the most suitable method is Gas-electric welding (if there is such an apparatus), but Gas-welding or welding with electrodes (preferably with direct current) can also be used. After welding, we align and clean the welding joints either with a file or an abrasive machine.
We prime and paint, admire our work, whispering to ourselves: not only gods burn pots.
Having completed the repairs with your own hands, you will save your money and earn the right to bang your fist on the table and ask: “Who is the boss in the house?”, But waste your time. The choice is yours.
We make a video of replacing thresholds on a Gazelle car.
The car arrived with practically no thresholds, "porch", wings, all the metal rotted away. I had to order rotten body parts and fasten them first with self-tapping screws, in order to try on how the door would walk, and then start welding.
Video of replacing thresholds on a Gazelle car:
The result of the work on replacing the thresholds on the Gazelle, at the end of the video, they are primed, it remains only to paint, all the parts turned out to be perfectly bent to each other. The door moves freely.
Regardless of whether you have a new car or not, sooner or later you have to deal with threshold breakdowns. This problem is caused by the poor quality of roads, a large number of holes, or just a love of extreme driving. It is quite possible to repair thresholds on a car with your own hands: what is needed for this - we will find out further.
Material content [open]
Thresholds on a car play several roles at once:
- Protect car from mechanical damage, scratches, deformations, etc.
- Help passengers when exiting and entering the salon.
- Protects body sills.
- They are a stylish addition to the car, making it visually more attractive.
Repair of thresholds on a car must be carried out in accordance with the design. It can be different: plastic, metal, chrome, with or without backlighting. Thresholds may or may not be removable, which must also be taken into account during repair work.
For non-removable elements, a special repair technology will be required. Such sills are securely welded to the surface of the car, so you will have to work carefully so as not to damage the surface of the car.
To repair the thresholds with your own hands without welding, you will need:
- special solution for removing rust;
- epoxy adhesive;
- solvent;
- aluminum powder (silver);
- sandpaper;
- putty;
- fiberglass;
- glue brush.
This technology will help to cope with rust even in the deep layers of the threshold and prevent its further spread. First you need to thoroughly remove the rust with a solution. Next - dilute the epoxy resin with silver and hardener and apply to the degreased surface of the threshold. Next, pieces of fiberglass are applied to the glue surface (there should be at least 4-5 pieces), which are then rolled with a rubber roller, for greater bonding to each other.
Now we are waiting for polymerization, which takes about 12 hours. At the final stage of the implementation of this method, it is necessary to grind irregularities, apply a primer, and only then proceed to painting.
Important! Bodywork and sills repair can also be done fiberglass (fiberglass), you can learn more about this technology in the section “Body repair ".
To repair the thresholds of a car with our own hands, we need a base plate (or workbench), a grinder, a welding machine and special tools for straightening. Sometimes a drawing tool can come in handy.
The repair technology is as follows:
- If minor repairs are required, then first use a hood to correct unevennessto smooth the surface. For this, you can use a spotter or an inertial puller.
- If a more serious body repair is needed, then you will need to remove the doors and take out the seats. This will prevent damage to them. After that, straightening is performed: a square-shaped window is cut out in the side of the threshold, through which the damage is straightened using hydraulic tools, anvils or hoods. When the work is completed, the window can be welded.
- Also, the threshold can be welded along the seam where it was welded earlier. In this case, straightening will be done using an anvil.
Be careful when working with welding. Be sure to use special gloves and a face shield.
The amount of work with the thresholds on the Volkswagen Passat B 3 will independently depend on the degree of their damage: sometimes you have to resort to extreme measures and use a partial replacement of a part. Experts give the following recommendations:
- It is best not to save on repairs and, if necessary, replace old damaged parts with new ones.
- The highest quality repair result will be obtained only with the use of a welding machine.
- It is not recommended to use iron and zinc thresholds when replacing: they are not very durable and take a long time to install.
On the market there is a fairly large range of thresholds for body repair of the Passat B3. The best option is to choose strong, close to "native" thresholds, they will last longer and will be convenient to install.
During repair work on the thresholds of this model, it is important to consider the following features:
- Rotten thresholds need to be replaced with new ones, trying to save on this will be more expensive for yourself in the future.
- At the end of the repair work, it is especially important to use an anti-corrosion compound.
- For this car model, it is better to choose plastic sills.
Body sills for Honda can be purchased both new and used. When choosing the latter, take into account their degree of wear and tear, pay attention to the price. Do not skimp on repairing your car yourself: then it will last longer.
Repair of removable thresholds on any car can be done quite easily with your own hands. This is due to the fact that this part can be processed simply by removing it, separately from the car. A very convenient option with a minimum of costs. However, here you should pay attention to some features:
- Removable thresholds wear out faster and in case of damage (especially mechanical) they will have to be replaced with new ones.
- Replacing the thresholds is very quick and does not require additional efforts or tools: the main thing is to choose a suitable replacement part.
- Slight curvatures of removable thresholds can be easily straightened with hoods, and slight corrosion can be corrected with a thin layer of putty.
Self-repair of car sills is available even for beginners, especially if we are talking about minor damage. However, if the damage is serious and you do not know how to solve the problem, then it is better to contact the specialists from the auto repair shop.

Welcome to blog my.housecope.com/wp-content/uploads/ext/2102!
In this article, we will consider how to replace thresholds with your own hands.
The threshold is a stamped panel that is a structural part of the car's structural body.
In the monocoque structure, the sill panels provide structural reinforcement that affects the rigidity of the vehicle underbody as well as torsional rigidity. While the front and rear have zones of planned crumpling, the side skirts provide a mid-body stiffness that should remain as intact as possible in an accident. Thus, the safety of the driver and passengers depends on the state of the thresholds.
Thresholds, especially their lower part, are often overlooked during washing. Road salt and other contaminants left on them accelerate the occurrence of corrosion. Also, these elements are constantly exposed to stones and sand flying off the road while driving and acting as an abrasive.
Since the thresholds are a closed, unventilated structure, they are vulnerable to corrosion. The worst aspect of threshold corrosion is that it starts from the inside and spreads outward. Thus, corrosion becomes visible when the threshold has already been significantly destroyed. In advanced cases, it is even impossible to use the special jacking points to raise the machine, since these areas have lost their strength due to corrosion. Exhaust gases that can get into the car interior can become another problem caused by both the thoroughly rusted sills and the underbody.
The outer part of the threshold is not the main power part of this structure. It provides rigidity to the body, but the bulk of rigidity is provided by the internal reinforcement, the connector and the interior of the sill. These panels are spot-welded together to form a box-shaped hollow structure that takes up the bulk of the loads. This design gives the vehicle longitudinal strength. The outer part of the sill provides a more cosmetic function.
Each inner part of the sill plays a role in providing structural rigidity. The entire sill structure reinforces the underbody.
- The inside of the sill is the part that can be seen from the inside of the car.
- Connector - This part can be seen from underneath the vehicle.
- The internal reinforcement is usually a flat steel element stamped for reinforcement.
- The outer part of the threshold is the part of the threshold that can be seen from the outside, and it is called the threshold.
The design of the threshold for a particular vehicle may differ from that shown in the illustration.
- You need to raise the car and level it.It is better that the body is supported evenly at several points to avoid skewing of the body.
- 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 the 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 have to remove the front bumper and headlight.
- If the threshold is being replaced due to corrosion, then it is necessary to clean the area around the rusty places with a margin in order to determine the boundaries of the rust. Thus, it is possible to understand which areas of the threshold can be left and which ones need to be cut out.
- To replace the thresholds, it is necessary to dismantle some interior details, such as plastic cladding, seats, and a rubber seal. The carpet can be rolled up.
- Protect the paintwork of the car, glass and interior from the ingress of sparks from welding and grinders.
- Disconnect and insulate the battery terminals before welding.
- When welding the thresholds on the flanges, through the holes, position the welding torch with the wire in the center of the hole so that the wire touches the metal to which the panel will be welded. It is necessary that the electric arc is formed precisely on the metal to which the panel will be welded, and not on the edge of the hole. Start cooking in this position and do not move the welding torch until the hole is nearly full. Then move the torch in a spiral motion towards the edges. So the penetration to the welded metal will be good and the welded joint will be strong.
- Sand the welds. When stripping, do not remove too much of the seam as this will weaken it.
- Make anti-corrosion protection. Epoxy primer can be applied directly to the weld prior to overcoating. Treat the threshold from the inside with an anti-corrosive spray compound through the technological holes.
Repair manuals usually mention two types of connections between the new threshold and the remnants of the old one. This is an overlap joint and a butt joint with an insert. A simple butt joint can also be used. Let's take a look at the features of these connections and how they are implemented.
Butt joint with insert
The connection of the old and new parts of the thresholds is reinforced by inserts made from the remains of the same threshold. Butt joint with insert allows to achieve a smoother surface than overlap, which does not require a lot of putty to level. The insert makes it easier to join the new threshold, reduces the likelihood of burn-through during welding, and also reduces heat distortion during welding by dissipating heat. The connection is stronger. Depending on the connection point, the insert may not always be used. Such a connection is usually applied at the edges of the sill. Where the threshold meets the B-pillar, an overlap or butt joint without an insert is usually used.
The size of the inserts can be from 5 to 10 cm. Depending on the configuration of the threshold, the insert is cut into 2–4 parts. The flanges are cut, with the help of which the spot welding holds the parts of the panels together. Thus, the inserts can normally fit inside the thresholds.They can be welded through drilled holes (8 mm) or temporarily screwed in with self-tapping screws, the holes from which are then welded. The inserts must be treated with welding primer. When joining parts of the thresholds, it is necessary to provide a gap of sufficient size so that the molten metal during welding normally penetrates to the insert, and it is welded together with two parts of the threshold. The width of the gap depends on the thickness of the metal and must be at least 1.6 mm and not more than 3.2 mm.
Lap joint
When connecting with an overlap, the old threshold should be marked and cut so that there is a margin of a few centimeters for the overlap. A new threshold is placed on top of the remains of the old threshold. Further, along the line of the edges of the new threshold, welding is performed with an airtight seam. The main advantage of this type of connection is the ease of joining the new threshold with the remnants of the old one. No need to carefully trim the edges. This is especially true when you have to join complex-shaped places, for example, a connection with a B-pillar. With an overlapping connection, there is less chance of burn-through through the metal. The disadvantage is the need to use a larger amount of putty when leveling the joints, as well as a predisposition to the appearance of corrosion on the reverse side of the threshold, due to the complexity of the anti-corrosion treatment of such a joint from the inside.
Butt joint
Butt joint requires careful adjustment of the new threshold with the remnants of the old one, as well as a certain skill when welding. The gap between the parts to be welded should be approximately equal to the thickness of the metal to be welded. A butt joint without an insert turns out to be less strong, but this is not critical, since the outer part of the threshold does not take on the entire load. If implemented correctly, the docked place turns out to be flat and requires a minimum amount of putty, and is also normally treated with an anti-corrosion compound on the reverse side of the threshold by spraying with special agents.
Repair of the Gazelle thresholds should be done when damage, distortions, dents and corrosion, in advanced cases, holes become noticeable visually. Basically, the thresholds are made of steel, aluminum, alloyed with chrome, therefore, the damage to them is the same as on other similar elements. The service life of the thresholds is up to 7 years and even more, of course, if you did not have an accident, did not touch the threshold during inaccurate parking and did not damage it with a jack during unskillful repairs on your own.
Thresholds for Gazelle are of different types: removable and non-removable, internal and external, they can be welded to the bottom of the body, or they can simply be bolted. To extend their service life, they can be painted, sometimes special plastic linings are installed on them, a silicone or rubber seal can go along the edge, often there is an anti-slip corrugated liner on the outer sills. The threshold can be reinforced to support loads of up to 200 kg.
The cost of repairing thresholds in St. Petersburg:
Repair of the Gazelle thresholds depends on the degree of damage, on whether it can be done without removing the threshold. The most common repair method is with a spot welder, or spotter. If there are holes, steel patches are put, dents can be removed with the help of straightening. In our car services, we will carry out repairs using special equipment, including, if necessary, we will pull out dents with hydraulics. After the repair, we will treat the thresholds with anticorrosive or install electrochemical protection, depending on your desire.
You can repair the Gazelle thresholds yourself if you know how to handle the welding machine and the damage is small. Sometimes you can even get by with the repair with epoxy mastics and special fabric, but this will be a short-lived repair. Therefore, we still recommend that you contact our car services to save time, money and effort, carry out guaranteed high-quality repairs.
When to repair thresholds:
- Externally visible dents, holes, distortions;
- It is required to replace the linings, seals;
- Damage to the thresholds is small and does not need to be changed, but repairs can be done.

Thresholds are not the only vulnerability of the vehicle, and arches and the bottom of the car often suffer along with them. This happens not only due to unscrupulous car care, but also due to the "fatigue" of the old metal, as a result of which corrosion appears. In such cases, the damaged areas must be repaired or replaced. True, in practice, the bottoms of cars are amenable to restoration, and new arches and thresholds are usually installed. In both cases, it is important to carefully handle metal cuts - this is the first condition for the reliability of the replacement.
There may be several reasons for the need to repair thresholds. However, the most common among them are the appearance of rust (corrosion) or severe damage resulting from an accident or severe mechanical wear (sometimes this happens). In both cases, before proceeding to replacing the thresholds, it is necessary to assess their condition and understand whether it is necessary to change the entire part or replace only the damaged part. This can be helped by the determination of the limits of the corrosive effect on the metal, expressed in the absence of a paint-and-lacquer coating or the appearance of air formations under it. In the latter case, a clear sign of this is the easy separation of the paint, for which it is only necessary to touch it with some instrument with a metal tip.
Like any other type of repair work, replacing car thresholds requires certain tools. It includes: a workbench, a set of screwdrivers, a welding machine, a pneumatic chisel, an angle grinder (commonly referred to as a "grinder"), various tools for straightening. You may need some other tools (for example, wrenches) to dismantle the fasteners, but often the listed components are sufficient.
Before proceeding with the direct replacement of the thresholds on your car, you need to understand their types. The fact is that there are two options for these elements: removable and non-removable (they are much more common).In the latter case, the repair work will take a little longer, because the thresholds are welded to the base of the body and form a single whole with it, which means they will have to be cut out.
If your car is more than 10 years old, then, most likely, it has non-removable thresholds, and repairs will not be an easy task. Nevertheless, subject to certain rules and strict adherence to all stages of repair measures, you will succeed.
To begin with, consider the process of replacing removable thresholds.
• After unscrewing the screws, dismantle the parts;
• If the thresholds need to be straightened, it can be performed on any hard surface (for example, on a workbench) using a special straightening tool as a tool;
• In cases where the problems are over and the parts do not require replacement, the thresholds are returned to their original place. True, it should be noted that the installation of thresholds for different car models may have its own characteristics, which will help you learn about the technical documentation of the vehicle.
It makes no sense to repair plastic products either, because they do not lend themselves to editing and straightening at all, which means that they can be considered an ordinary consumable. (wear out quickly, but do not corrode). For correct and tight installation of plastic thresholds, it is enough that the holes for the self-tapping screws are at a distance of no more than 4-5 centimeters from each other, and after you manage to install the door sills, do not forget to anti-corrosion treatment of all fasteners.
Now consider the option of replacing non-removable vehicle sills. First you have to dismantle the car doors and side fenders. In fact, this is not a difficult task, because on most modern cars, these elements are fastened with bolts, and the procedure for their removal does not take much time.
Then the old or damaged threshold is cut (cut down) along the line of the welding joint (for this purpose, a grinder, a drill with a small diameter drill or a sharp chisel is used). In the event that the elements are damaged by through corrosion, it will be necessary to replace the trim and the connector. Note! The easiest way is to remove the sills in parts: first near the front door, then next to the rear door, and finally at the B-pillar between the doors.
Before installing a new part, it is necessary to drill a number of holes along the line of connection of the overlays with the threshold. (the hole diameter is 5 mm, and the distance between them should be about 5 cm). This completes the preparatory stage, and you can proceed to welding a new body element. It is worth noting that all actions must be performed as carefully as possible, precisely fitting the part to the mating parts, thereby ensuring the rigidity of the entire structure.
It is better to start welding work from the upper part of the threshold, gradually moving to the lower part, and the part should be pressed in the direction of welding. After finishing welding, do not forget to carefully grind the seams with a grinder, thereby leveling the entire surface.
If grooves and irregularities appear, apply a thin layer of repair putty to the area, and after it dries, carefully level the surface flush with the metal part. Upon completion of all work, the surface of the thresholds should be well degreased with special means and covered with a layer of soil, after which you can proceed to painting the surface of the element and reassembling the body (doors and fenders are installed in their places).
