Well .. at first I went by car to all kinds of picnics, shalyki, fishing. Everything was great, if not for some points:
not everywhere you can go (good places are usually inaccessible for ordinary cars)
where you can go - there are already whole hordes of vacationers with all the attendant
you won't load too much
after almost every trip there was a bill from the service for certain details, a special inconvenience was represented by bushes that scratched the car and its appearance was ditched specifically
I read forums and all kinds of reviews. I decided to buy a booze, tk. a large volume was required, I did not want to bang money into this venture, and in general, I did not know what the hell I needed all this for.
I searched for a long time, found on an ad for 1500 ye in Fryazino the necessary loaf “ideally and not rotten” :). There was no question about the goat, tk. the car was supposed to be made for an expeditionary campaign with a bunch of junk on board.
At that time, there was no way to participate in the competition. Trips to nature with all that it implies. From 1 to 3 days.
Now trips from 3 to 20 days are a normal scenario.
With you, if necessary, take a satellite dish and a TV 🙂 So that it is not boring in the evening / at night 🙂
When I drove in and began to figure it out, a diagnosis was made - a complete overcooking. Moreover, I wanted to leave it on a standard loaf of rubber.
Then 35x12.5x15 wheels and disks turned up under the arm, and the task expanded beyond recognition. Looking ahead, if I had known how it would all end, I probably would not have taken it.
When you look at the UAZ 452 model, the first thing that comes to mind is the outline of a loaf of bread. However, it is just a godsend for our off-road, as it is an all-wheel drive all-terrain vehicle. Working in the most difficult conditions sooner or later leads to the need for repair and restoration of the car body. We will try to figure it out further on what the owners of the UAZ-452 have to face during operation, what most often "crawls out sideways", how to make repairs with their own hands, what spare parts and parts to use.

UAZ-452 is considered the oldest serial car produced in Russia. The first samples of an all-wheel drive two-axle vehicle left the Ulyanovsk conveyor back in 1965 and are still being produced. It is distinguished by simplicity, availability, reliability, and increased cross-country ability. The car is equipped with a carburetor-type power unit from ZMZ with a volume of 2.4 or 2.7 liters. It allows the UAZ to develop a maximum speed of 110 km / h. A 4-speed manual transmission is responsible for gear shifting.
An impressive clearance of 220 mm helps to overcome various obstacles. And for all its external unpretentiousness, the basic version of the UAZ is capable of carrying cargo weighing more than 1.2 tons. Excellent layout and characteristics to this day provide cars with popular love and constant demand. This car is used so intensively and in such conditions that the body and its individual elements are one of the first to suffer. Based on this, the main reasons for the violation of the integrity and performance of the hull elements are:
Traffic accidents that result in dents, cracks, chips, or scratches.
Hot spots or entire zones of corrosion that arise as a result of damage to the paintwork.This can be influenced by aggressive substances, which, for example, sprinkle roads in winter, or the presence of previously mentioned defects that were not eliminated (or it was done, but of poor quality).
The desire to improve the existing design.
Each of the reasons for the violation of the integrity and performance of elements has individual characteristics that affect the repair, its volumes and stages. The parts and parts required for this also differ.
Repair of UAZ car body elements is carried out in case of violation of their geometry (dents), integrity (cracks, corrosion, rot), paintwork (LCP). Almost each of these cases includes a preparatory stage and body painting. Preparation takes place approximately in the following sequence (depending on the volume of problems, some of the initial stages can be omitted).
The cars of the Ulyanovsk Automobile Plant were originally intended for military and national economic needs, therefore the undercarriage, frame and chassis were made of materials of increased strength. After the collapse of the Union, a lot of cars moved from state property to the private sector, continuing to serve faithfully. True, the UAZ body requires some attention, systematic restoration of the paint layer and removal of corrosion.
UAZs are quite maintainable and durable cars
Before starting the repair of the UAZ body, determine the degree of damage. Sometimes corrosion starts from the inside of the body, although the outer paint coat appears to be intact.
Wash and dry your vehicle thoroughly before scheduling repairs. Inspect the body for damage. Depending on the amount and size of corrosion, you decide whether it will be a DIY repair or send the car to a car service. Overhaul, or medium, is to be done.
So, you decided to repair the UAZ yourself.
You clean problem areas to a metallic sheen.
If the rust has eaten through the metal, you will have to put patches, weld them on the inside. Align the welding seams with an emery disc;
First, smooth out any dents on the metal;
Before applying the putty, wipe the body from dust, dry particles of old paint and then degrease.
Treat the car body with phosphating primer. This measure localizes the centers of corrosion, even if there are rust spots, and protects the metal from further oxidation. The protective primer is diluted with a solvent and applied in a thin layer from a spray gun.
The body of the UAZ has to be patched up with metal, you can't do without a welding machine
After the phosphating primer, walk with an acrylic primer so that the phosphate does not chemically react with the putty.
Now proceed to puttying. Apply the filler in thin layers, smoothing out any unevenness in the metal left after mechanical repairs. The putty is applied at least three times with intermediate drying and sanding of each layer.
The putty surface is primed in one or two layers before painting. Use a spray gun for priming. The dried primer layer is sanded to form a flat surface, to remove possible streaks.
Then 2-3 layers of autoenamel of the corresponding color are applied on the surface to be treated. Each layer is aged according to the time indicated on the can. Keep in mind that can dry times are for room temperature. If the temperature in the room is lower, the drying time of the paint will increase. Air humidity also affects paint drying no less than temperature. Sand each dried layer and wipe off dust with a sticky cloth.
In this chapter, you will learn an interesting way of how to repair a UAZ with your own hands., without using a welding machine.There will not be a word about fiberglass and epoxy - we will leave them for plastic, and for those would-be craftsmen who do not work conscientiously, but only to close the eyes of the customer. Respecting himself and his car, the owner, will not stick fiberglass with epoxy on the body damaged by rust. Because corrosion under such a patch will continue its destructive effect, and as a result, in a couple of months you will get an enlarged hole in this place.
On a metal body, especially if it is a UAZ loaf body, the patches should be made of metal. Find scraps of steel sheet close to the thickness of the body. Using a grinder, or a metal hacksaw, cut out patches from it to size, overlapping the holes on the machine body. Grind the cut out parts so that they do not stick out along the edges of the cuts, try on and grind to the attachment points. Use a strong soldering iron to tinkle the joints. Warm up the patch and put it on the tinned place, solder, while leveling the molten tin so that no protrusions form. Tighten gently with a hammer.
Let the patch cool. Check for strength. If done correctly, strength and durability are guaranteed. Sand your patch. So, using a soldering iron and tin, you can solder small patches on the body, on the door, and process the rest of the body parts. Tin, in addition to connecting it, also protects the metal from corrosion.
This method is no more expensive than fiberglass patches, but more reliable. This method allows you to carry out minor body repairs of any Ulyanovsk car.
Increasingly, the owners of the UAZ 452 model, popularly nicknamed the loaf, come to the need to modernize this machine. The body of the UAZ loaf is lifted, raised to increase cross-country ability. There are 2 lifting methods.
This option is easier to perform, and it provides greater stability to the machine in off-road conditions and when cornering, due to the fact that the center of gravity does not shift. The lifting of the body is carried out thanks to spacers that are inserted between the frame and the body and provide a rigid connection of these elements. The spacers raise the body by 8 cm, and if large wheels are installed, the car will become 15 cm higher. In this case, it is necessary to trim the wheel arches and fenders so that the wheels do not cling to them when cornering, and be sure to hang the mud flaps.
Increases the UAZ's ability to pass obstacles. True, in this case there is a risk of a shift in the center of gravity, the car will lose controllability and stability. The situation can only be saved by a comprehensive repair of the UAZ loaf body.
To begin with, we determine the optimal suspension height;
Please note that lifting is limited by cardan shafts;
You can reduce the likelihood of the machine overturning by expanding the wheel distance.
To do this, take wide wheels, larger discs. Rear axles are changed to "Bars" or "Spacer". Replacing disc brakes will help to increase the inter-wheel distance. Disc brakes from the Volga car are installed without fitting.
During the operation of the loaf, the rear doors are skewed, which begin to open spontaneously.
We start strengthening the UAZ body with our own hands from the floor. For this purpose, we raise the floor and inspect the condition of the underbody. The body is reinforced with a 20x40 profile pipe. The bottom profile is welded to the bottom waves. The first pipe is laid along the edge of the body so that the tailgate rests against it. The second is parallel, at a distance of half a meter. Stiffeners from the same profile are also welded along the side wall of the body. Profiles are installed along the ceiling, parallel to the floor pipes. Thus, the shaped tubes form a frame to which the body walls are welded. Spacers are installed between the upper and lower pipes at a distance of 50cm. The resulting frame is welded to attract sagging corners of the body, so that the rear doors are aligned.If you weld a sheet of steel to the profiles welded to the side walls of the body and spacers, you get a convenient cabinet for fishing rods and guns. A shelf for various little things is also formed on top. In the same way, by installing stiffeners, the side wall and the doorway of the side door are strengthened.
Strengthening the body, increasing the rigidity, and provide "kerchiefs" welded at the junction of the body sheets. Only the kerchiefs must be welded at a distance not exceeding 15 cm from each other.
Before closing the floor, inspect the bottom for rust, sand it, if necessary patch up with welding and treat with rust mastic. While the mastic is drying, cut out the floor parts from the plywood, cover them with linseed oil 2-3 times, let the linseed oil dry and lay the plywood on the floor. Then roll out the expanded polyethylene foam. On top is another layer of plywood coated with linseed oil. Lay the upper floor on top of the drying oil. It can be linoleum, or sheet steel, depending on what is planned to be transported in the UAZ.
The side walls inside also need renovation. Peel off the old panels, clean the side walls of the body from corrosion, treat with mastic. When the mastic is dry, roll out glass wool for thermal insulation, glue the foam polyethylene on it and sheathe the panels with the selected material on top. It can be plywood, and hardboard, and hardboard with dermantine. You decide.
There are two requirements for a car bumper:
Reliability and safety;
External appeal, aesthetics.
Ulyanovsk cars are no exception. Car owners of these cars install bumpers with kangarins on the UAZ 469 or “loaves” body, which, on the one hand, add solidity to the car, and on the other, protect the headlights and radiator from damage.
Requirements are made to bumpers and kangarins that they must comply with safety standards, therefore, in order to avoid problems with a valiant car inspection, we purchase suspensions from a trusted manufacturer.
In the conditions of bad roads, the UAZ becomes exactly the means of transportation that helps to get out literally from any place. Only these SUVs are subject to wear and tear and require repair. The parts and spare parts that are closest to the road surface experience the negative load most of all. From the article we will learn how to repair the body of a domestic car with our own hands.
ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe me? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"
In the common people "bobby" (UAZ 469) is the vehicle of the chairmen of large Soviet collective farms, and today the vastness of the Russian hinterlands roam. Another prototype, the "loaf", is a real minivan successfully operated off-road.
Both cars are subject to rapid wear of body parts due to hard operation, constant contact with a moisture environment, etc. On bumps and bumps, the chassis shakes, the elements of which also eventually deteriorate, no matter how good they are.
The good thing is that domestic cars can be repaired even in an open field, having a couple of wrenches with you. If you carry out the repairs in the garage with all the necessary equipment, the result will be impressive.
Often, when removing a layer of paintwork from the body of a used UAZ, the owners find large holes in the body parts. For those who do not have a welding machine, this problem is solved in 2 ways: either a special is called, or the UAZ is taken to the service station. If you have a machine or a familiar welder, everything can be decided on the spot. Also, you can do it yourself if the hole is small, the size of a matchbox.
So, in addition to welding, putty and fiberglass will help to close the hole.This repair cannot be called efficient or super effective, as it has drawbacks. On the other hand, this method is capable of providing at least a month's operation of the car. Then you can show the UAZ to a body repair specialist.
There are other ways to close the hole. In particular, by installing a metal patch. To do this, you need a powerful soldering iron, a piece of sheet (covering the hole completely) and acid.
The algorithm for carrying out this method is as follows:
Before putting the patch, it is necessary to tin the joints;
Put the patch on the hole (it should completely cover the hole);
Solder to the metal body using a high-power lamp.
You need to do everything so that the surface does not have protrusions. Deficiencies that arise in one way or another for a beginner are corrected with a hammer and the final operation with puttying.
