Do-it-yourself replacement of VAZ 2109 thresholds: signs and step-by-step process

Procedure for replacing thresholds on a VAZ 2107

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

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

Tips for replacing thresholds and protecting them during operation

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

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

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

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:

1. Sand the surface with high and low abrasive sandpaper.
2. 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.
3. Apply the first layer of auto enamel, wait for the paint to dry for 7-10 minutes.
4. Apply a second coat of paint.
5. After complete drying, apply protective varnish.

What is this?

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

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

You need to order this service in the following cases:

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

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

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

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

In what cases is threshold repair required?

The main reasons why repair of thresholds is required include: • Corrosion due to exposure to chemical reagents. • Incorrect use of the jack. • Inaccurate parking on the sidewalk. • Traffic accident. • Careless driving on rough terrain.

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

Pricing factors

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

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

How to choose thresholds for a VAZ 2110: average prices

Today, components for the Zhiguli line are manufactured by more than 20 licensed companies and more than a hundred small firms. The average price for a set with an amplifier is 2600 rubles. The assortment includes plastic and iron spare parts. It is recommended to select thresholds made from 300 series stainless steel with a minimum thickness of 1 mm.

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:

1. 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.
2. 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.

Types of services

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

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

Why do thresholds wear out?

Thresholds are load-bearing elements that provide the body with additional rigidity. Due to the fact that these parts are located in the lower part of the body, they are constantly exposed to negative factors:

• water;
• dirt;
• sand;
• stones;
• salt;
• chemical substances.

All this significantly reduces the service life of the thresholds. In addition, the mediocre quality of painting and anti-corrosion treatment of body elements from the factory leads to the fact that almost every owner of a “Nine” is faced with the need to replace the thresholds on their car.

Signs of the need to replace thresholds on a VAZ 2109

The appearance of even small areas of corrosion on the thresholds is the first sign that these body elements need to be paid attention to.

Minor corrosion of thresholds may not present any problems at first glance

At first glance, such areas may seem harmless, but if you examine them in more detail and clean them, it may turn out that under the layer of paint there is a serious source of corrosion or completely rotten metal.

With more detailed diagnostics of the threshold, through holes can be detected

It is important not to miss the moment when replacing the threshold is still possible. It often happens that the threshold rots around the perimeter and there is simply no need to weld a new part. In this case, more serious and labor-intensive body work will be required.

Threshold repair options

Repair of the body elements in question can be performed in two ways:

• welding patches;
• complete replacement of parts.

The first option requires less effort and financial investment. However, this is where its advantages end. If you follow the recommendations of specialists, then repairing the load-bearing part of the body with patches is not the best option. This is due to the fragility of such repairs.

It will not be possible to completely remove corrosion with partial repairs, and its further spread will lead to new rust and holes.

If you do not have the opportunity to completely replace the thresholds or the body element in question has minimal damage, you can partially replace the damaged area. To do this, you need to cut out the rotten place, clean the metal as best as possible from corrosion and weld a patch of body metal of the required thickness or use a repair insert.

Partial repair involves replacing the damaged area with a piece of body metal or a repair insert

After this, the threshold is carefully protected from corrosion in order to maintain its integrity for as long as possible.

Approximate prices

Digesting thresholds in Russia on a VAZ 2107 car is not cheap. So, in most service stations in the country, this service costs approximately 5,000-15,000 rubles for the restoration of one lining . This price includes the cost of such work:

• Digestion – from 5000 rubles .
• Straightening the linings - about 3000 rubles .
• Painting a part with paint and varnish – about 3,000 rubles .
• Removal of the threshold - from 2000 rubles .
• Reinforcement - from 4000 rubles .
• Digestion to order with installation - about 10,000 rubles .

Prices are for one threshold. The cost of urgent work and visiting an auto repairman will be individual in each case.

How to repair thresholds

Sequence of work for removable thresholds:

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

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