Purpose, protection, repair and replacement of thresholds on the VAZ 2106
Content
The first copies of the VAZ 2106 rolled off the assembly line more than 40 years ago. Despite this, many of them continue to be used today. It is clear that over time, on any, even the highest quality, car, problems appear not only with the paintwork, but also with some parts of the body. One of the parts that most often corrode are thresholds. Having the necessary tools and basic skills, you can protect, repair or replace the thresholds on the VAZ 2106 with your own hands.
Description and purpose of thresholds VAZ 2106
Some novice motorists believe that the thresholds on the VAZ 2106 or any other car play only a cosmetic role and act as tuning. This is not so - the thresholds of the car 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;
- ensure the convenience of boarding and disembarking passengers.
Bearing element of the body
If you look at the design of the VAZ 2106 thresholds, then they consist of the following elements:
- the outer panel is in plain sight and is called the threshold;
- the inner part - it can be seen from inside the car;
- amplifier - located inside the box;
- connector - visible if you look at the threshold from below.
The threshold of the car 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. For this, spot welding is used. The result is a box-like structure, which provides the necessary rigidity.

Jack nests
The jack sockets are welded to the car body. If it is necessary to replace a wheel or other elements, it is necessary to raise the car. For this, a jack is used, which is inserted into a special hole on the jack socket.
To make it easier to install the jack in winter or slush, home craftsmen close the hole on the nest with a regular champagne cork. Thus, the nest always remains dry and clean. This allows not only to quickly and easily insert the jack into it, but also extends the life of the entire jack socket.
Do-it-yourself repair of thresholds
On the VAZ 2106, as on any other car, repair or replacement of thresholds may be necessary in such cases:
- corrosion;
- mechanical damage.
In order to replace thresholds with your own hands, you need to have not only basic skills for carrying out such work, but also the necessary set of tools:
- well sharpened chisel;
- powerful screwdriver;
- a hammer;
- gas welding or grinder;
- spot welding, if not, then MIG welding can be used;
- electric drill;
- a metal brush used to clean the internal cavities of the body from corrosion, which will be visible after the dismantling of the thresholds.To repair thresholds, you will need simple and affordable tools.
Repair thresholds VAZ 2106 without welding
If you do not allow the mass destruction of this body element by corrosion or its mechanical damage is insignificant, then you can carry out repairs with your own hands and without the use of a welding machine. To perform work on restoring the appearance of the thresholds, you will need the following tools and materials:
- epoxy adhesive;
- fiberglass;
- rubber roller;
- rubber spatula;
- rust remover;
- solvent;
- sandpaper;
- putty;
- aluminum powder, popularly called "silver";
- primer;
- paint that matches the color of the car. Some motorists paint the thresholds black.
The procedure for repairing thresholds VAZ 2106 without the use of a welding machine:
- Preparation of the damaged area. The place of damage is cleaned of rust with sandpaper and a special liquid. Cleaning should be carried out qualitatively, until the appearance of pure metal.The damaged area is cleaned to bare metal
- Preparation of epoxy resin. Epoxy glue is prepared according to the instructions. Due to the fact that after drying it becomes strong, but brittle, it is necessary to add aluminum or copper powder to it. Small metal particles will play the role of reinforcement.To reinforce epoxy glue, aluminum or copper powder must be added to it.
- Repair of damage. Before applying the finished composition, the prepared place on the threshold is degreased with a solvent. A layer of glue is applied, then covered with a piece of fiberglass of the appropriate size. Make several such layers, with each piece rolled with a roller to remove air. It will take at least 12 hours for the epoxy adhesive to completely cure.For the patch, fiberglass and epoxy resin are used.
- Application of putty. It may happen that after applying the fiberglass, it falls a little and a dent forms. In this case, automotive putty is used to level the surface. A rubber spatula is used to level it.
- Processing of the restored site. Do this with sandpaper after the glue or putty has completely solidified. High-quality cleaning and leveling of the restored area is carried out.
- Coloring. First, the surface is coated with an automotive primer, and after it dries, it is painted.After painting the patch, it is almost imperceptible
As you can see, if there is minor damage to the VAZ 2106 threshold, even if the hole is through, repairs can be made without the use of a welding machine.

Replacement of thresholds
It is clear that the use of epoxy resin to repair thresholds is a temporary solution. It can only be used for minor defects. If the threshold is severely damaged by corrosion or has received serious mechanical damage, then it will have to be completely replaced, and in this case, welding is no longer enough.
Threshold replacement procedure:
- Level ground preparation. To carry out work, the car must be installed on a solid and even surface. This is especially important for old and rotten cars. During repairs, the clearances of doors and other body elements may change. To keep all the gaps, stretch marks are fixed in the doorway.
- Removing doors. To facilitate the work, it is better to remove both doors. Before this, it is necessary to indicate the location of the loops - it will be easier to install them after the repair.To facilitate replacement of the door sills, it is better to remove
- Removing the outer sill panel. Do this with a grinder or hammer and chisel.The outer part of the threshold is cut off by a grinder or knocked down with a chisel and a hammer
- Amplifier removal. After removing the outer panel, access to the plate with holes will be open. This is the amplifier, which is also removed.
- Surface cleaning. With the help of a brush for metal, as well as a grinder or a drill with a special nozzle, they clean everything from corrosion. Especially carefully process the places that will be welded.
- Checking the amplifier for compliance. There are times when it is a little longer and you need to cut off an extra section.Check if the length of the amplifier matches, and if not, then cut off the excess
- Amplifier installation. Do this first from above, then from below with the help of two parallel seams.The amplifier is fixed and then securely welded
- Fitting of the outer threshold panel. First, they try it on and, if necessary, cut it to the required size.
- Threshold installation. First of all, the transport soil is removed from the surface. To protect the threshold from corrosion, the surface is coated with a special compound. Fixation is performed with screws or clamps.They try on the threshold and if everything is fine, fix it with clamps or self-tapping screws
- Door installation.
- Checking gaps. The set threshold should not go beyond the door arc. If everything is fine, then you can weld the installed element.
- Threshold fixing. They begin to weld the outer panel, moving from the middle rack to one side and then to the other side.They begin to weld the threshold, moving from the middle rack to one and then to the other side
- Connector fastening. They do it last. The connector is welded from below to the floor. To prevent scale from falling on your head, you can make holes in the floor. After that, tighten the connector with a jack and cook it from the inside of the passenger compartment.
- Priming and painting the threshold.Usually thresholds are painted in the color of the car

Anti-corrosion treatment of thresholds
In order to postpone the repair or replacement of thresholds on the VAZ 2106 as much as possible, it is enough to carry out their anti-corrosion treatment correctly and on time. Experts recommend anti-corrosion treatment of thresholds once every two years. This will be sufficient to prevent corrosion damage to the specified element. It is desirable that the first processing be done by specialists, and only then it will be possible to maintain the threshold in a normal state on their own.
To process the thresholds with your own hands, you need to buy an anti-corrosion agent, it can be Car System, Novol, Rand or similar. You will also need an anti-rust liquid, a metal brush, sandpaper. The following work is carried out in personal protective equipment:
- The car must be thoroughly washed and dried.
- Use a brush and sandpaper to remove rust from the threshold.
- Coat the surface with an anti-rust agent and allow it to dry completely.
- Treat the thresholds from the inside with an anti-corrosion compound. It can be either liquid or in the form of an aerosol.Anti-corrosion composition completely covers the inner surface of the thresholds
Outside, you can treat the thresholds of the car with anti-gravity or gravitex. To do this, the car body is closed and only thresholds are left. The acquired composition is applied from the can in several layers, and each layer must dry for at least 5 minutes. It is enough to apply 2-3 layers.

Threshold boost
To increase the thresholds, you can purchase a factory amplifier. Often home craftsmen make it on their own, for this a metal strip 125 mm wide and 2 mm thick is used. A piece of the required length is cut off from it, in which holes are made every 6-7 cm, and the amplifier is ready. To obtain maximum body rigidity, some craftsmen reinforce the thresholds with a profile pipe.
To strengthen the location of the jacks, you can additionally weld a metal plate, and only then fix the jack.
threshold decoration
In order to make the appearance of their car more attractive, many owners install special plastic lining and moldings on the thresholds.
Door sills
Door sills 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 the paintwork from mechanical damage;
- the ability to hide minor defects;
- improving the appearance of the car.
Moldings
Threshold moldings are rubber-plastic products that are mounted on regular places of the VAZ 2106. They are mounted on double-sided tape. The presence of hollow sections inside allows you to dampen minor mechanical shocks. Such elements also decorate the appearance of the car.

To ensure the maximum service life of the car body, it must be regularly inspected and any malfunctions eliminated in time. This is especially true of thresholds, as they are most exposed to the negative impact of external factors. In addition, the thresholds, unlike the bottom of the car, are in a prominent place and even the slightest damage to them will negatively affect the appearance of the VAZ 2106.
