How to Remove the Body from the Frame of a UAZ Bukhanka
The UAZ body with the name bread is indexed with marks 452 or 3741. Today, these modifications of UAZs are called 2206 and 39625. The onboard versions of this body, which have the unofficial nickname “puzzles,” are located at home.
Just as our client remains a model manufactured at an automobile plant in Ulyanovsk, bread for other bread is distinguished by improved cross-country ability, body, body frame and the presence of a traditional “four-wheeled” engine. WARNING! I found a very common way to reduce fuel consumption! Don't you believe it? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! More "
The production of UAZ cars and small trucks began in the 1950s. By the end of the 5th decade of the last century, the Russian automobile industry was producing the UAZ 450. The model was created as a replacement for the outdated Gaz-69.
Seven years later, the 452 wagon arrives with improved powertrains that consume much less fuel. So, the engine was already installed from the Volga, and not from Pobeda, as before. Checkpoint from Gaz-24. The body length also changes.
The next reform was carried out by the manufacturer in 1985. The UAZ received new indexes, although drastic changes and, as you might say, restyling did not work.
Regarding the design features of the body:
- Bus body type for up to 10 passengers;
- Passenger and cargo van, capable of accommodating 6 riders and 450 kg of cargo;
- The van just throws out 800kg of cargo when fitted with the new seats.
UAZ bread has a rather warm body, which is simply explained by the presence of 2 heaters.
We also note that the UAZ bodies have a wooden platform on another metal. Today, the ascetic interior of the cabin, a huge selection of painted body parts, devices with simple equipment, etc. differ from the features of the UAZ.
Replacing the loaf
Some categorical configurations have only existed since the 1990s. The engine, gearbox and chassis have been modernized. Which, in a sense, improved the interior components.
Refurbishment or replacement

Compared to restoration operations, replacing the body looks like a much more reasonable and sober decision. To carry out competent repairs, you need to know the specifics of the work, have high-quality equipment, etc. If the repairs are carried out at a service station, you will have to pay a lot of money, and a well-worn body is unlikely to be restored so that it will last for several years.
On the other hand, replacing the body is also not an easy operation, no matter how it may seem at first glance. One of the most complex types of restoration from a technological point of view, involving the reinstallation of a metal frame - this is exactly what this type of work is called.
The UAZ body is most often replaced in case of serious defects resulting from severe accidents or serious accidents. In order for its replacement to be successful, it is customary to use numerous equipment and tools.
It is advisable to carry out body replacement in a specialized car service center. As a rule, the full range of services is provided here, including paperwork.
It is worth knowing that the car body is made of several elements. These parts can either be replaced individually or in combination with other body parts. So, after an accident, in most cases only part of the frame suffers. You can replace only the front or rear part, thereby saving on replacement costs.
In addition, body parts such as sills and fenders are often damaged during an accident. You can replace them yourself; no re-issuance of documents is necessary.

How to Remove the Body from the Frame of a UAZ Bukhanka
Bearing system, UAZ frame.
from the book by E. N. Orlova and E. R. Varchenko “UAZ cars” for maintenance and repair of UAZ vehicles
Device. UAZ cars have three types of frames. Welded frames consist of two longitudinal elements connected by transverse elements. To facilitate installation and removal of the engine, one of the cross beams is removable and screwed to brackets welded to the side elements of the frame. The remaining sections are welded to the side elements using arc welding.
Truck frame
UAZ-3151 and UAZ-31512 have a second removable cross member.
All brackets mounted on the frame, with the exception of two brackets for attaching the fixed ends of the front springs, are arc welded. The mounting brackets for the fixed ends of the front springs are glued to the side members of the frame. The front ends of the mounting bolts have a hexagonal front bumper and upper side members flanges. hooks When towing the rear frame crossmember, four towing bolts are attached to a reversible, enclosed towing device equipped with a rubber spring. In an embodiment, UAZ-31512 vehicles have a rigid device without an elastic element, intended for short-term towing of a trailer. The two rear bumpers are made of 4mm thick 65G spring steel, mounted on the rear cross member and the end of the studs on both sides of the towbar.

If you have not found the necessary documentation for UAZ repairs, we recommend visiting the UAZBUKA . UAZBUKA forum , a forum where you can get a live answer from UAZ car owners. On the UAZBUK forum you can sign up for off-road competitions. Our answers to car repairs are available by phone.
On cars of the UAZ-3151 and UAZ-3741 families with four-point engine mounting, as well as all models based on them, three types of frames were installed. All frames are welded and consist of two box-shaped spars of variable cross-section, connected to each other by cross members.
One of the cross members, for ease of installation and removal of the engine and gearbox assembly with transfer case, is made removable and bolted to brackets welded to the frame side members. The remaining cross members are welded to the side members. Brackets for springs, shock absorbers, power unit supports and body mounts are attached to the side members.
Frame of passenger cars of the UAZ-3151 family, design, dimensions.
The frame of cars of the UAZ-3151 and UAZ-31512 families has a second removable cross member. All brackets installed on the frame, except for two brackets for fastening the fixed ends of the front springs, are welded. The mounting brackets for the fixed ends of the front springs are riveted to the frame side members.
The front bumper is attached to the front ends of the side members with six bolts, and tow hooks are attached to the upper flanges of the side members and, on some vehicles, a roll bar. A double-acting towing device is attached to the rear cross member of the frame with four bolts. Two rear bumpers made of 65G spring steel, 4 mm thick, are mounted on the rear cross member and the ends of the side members on both sides of the towing device.
Frame of utility vehicles of the UAZ-3741 family of wagon layout, structure, dimensions.
The frame of the UAZ-3741 van has a third removable cross member. Spring mounting brackets are riveted to the frame side members, and towing hooks are attached to the bottom of the front ends of the side members. The remaining brackets are welded to the frame.
At the front ends of the frame side members, brackets are welded to which the bumper is attached. The rear bumper consists of two parts and is mounted on brackets welded to the rear ends of the frame side members. The spare wheel suspension brackets are bolted to the fifth cross member of the frame.
A rigid towing device is secured to the last cross member of the frame with four bolts, on both sides of which the footpeg brackets are welded to the frame cross member. The frame of the UAZ-3741 car is also installed on cars of the UAZ-3962 and UAZ-2206 families.
Frame of trucks of the UAZ-3303 family, design, dimensions.
The frame of trucks of the UA3-3303 family is not interchangeable with the frame of vehicles based on the UAZ-3741 and differs from it in the shortened rear ends of the side members, the absence of a rear bumper and footrest brackets, a spare wheel mounting bracket and on-board platform mounting brackets.
Towing device for UAZ cars.
The towing device of UAZ-3151 vehicles is double-acting, closed type, equipped with a rubber elastic element that softens shock loads when operating a vehicle with a trailer. The towbar is equipped with a latch that closes its mouth and is locked in the closed position by a “pawl” under the action of a spring. To eliminate spontaneous disengagement of the trailer drawbar from the hook, the “pawl” in the latch is locked with a cotter pin.
In a variant version, UAZ-31512, UAZ-31514 and UAZ-31519 vehicles are equipped with a rigid towing device without an elastic element, intended for short-term towing of a trailer.
The UAZ-3741, UAZ-3962 and UAZ-2206 cargo-passenger vehicles of the wagon configuration are equipped with a rigid towing device, which is not designed for long-term operation with a trailer. Along with a rigid towing device, a double-acting towing device with an elastic element can also be installed on the frame of a UAZ-3303 truck.
Maintenance of UAZ vehicle frames.
During the next maintenance, it is necessary to clean the frame from dirt and, by external inspection, check the condition of its side members, cross members, brackets, welded and riveted joints. If necessary, tighten the bolts securing the bumpers, removable cross member, towing device and engine mudguards. Particular attention should be paid to the left side member in the mounting area of the steering housing and the first frame cross member.

Re: How to remove the body from a UAZ
The simplest option: One person takes the hijack, jacks up the face or rear first, and substitutes the sawhorse. He does the same procedure on the other side. Then he rolls out the frame - ALL.
Reverse the procedure in reverse order.

Re: How to remove the body from a UAZ
We also installed the body in four of us. And I filmed it alone! I moved it from the frame onto a 2-wheeled cart so that the center of gravity of the body was approximately above the axle and rolled it with my hands to the far corner of the site.

Just slip powerful boards over the entire length of the body, and jack them up... Otherwise, the body will break at any moment. They scare you with this on UAZbook

Preparing for the Loaf Elevator
Lifting options for UAZ Bukhanki
Owners of Bukhanka, when starting to tune this car, first of all ask themselves the question: “How to raise a UAZ loaf?” We will try to answer this question in this article. So, first of all, let's look at the UAZ elevator methods. It could be:
- UAZ body lift
- Loaf Suspension Lift
Both options have both advantages and disadvantages. Thus, the Bukhanka body lift is easier to implement and also has a greater degree of safety. This is explained by the fact that this method of lift only slightly shifts the car’s center of gravity, which helps ensure the Loaf’s stable behavior on turns and other difficult sections of the route.
If we talk about the suspension lift, then there is some danger here due to the increase in the center of gravity. But at the same time, this method significantly changes cross-country ability for the better.
Choosing a kit for the UAZ loaf elevator
As we can see, there are several ways to raise the Loaf. Therefore, it is possible to determine which UAZ Bukhanka lift kit will be needed only by deciding on the choice of lift method. If you plan to do the lift yourself, you can buy a lift kit from a store. Such kits differ in the composition of the parts and elements included in them.
Thus, a kit for a Loaf elevator may contain:
- spring-frame spacers;
- spring-frame spacers
- bolts;
- nuts, etc.
Changing wheels
As you know, the cross-country ability of a vehicle directly depends on the wheels. Considering that the UAZ wheels are covered in fairly hard and not too large rubber, before proceeding directly to the elevator, it is necessary to mention the wheels. In addition, the tread pattern on the Bukhanka tires leaves much to be desired. All this suggests that it would not be superfluous to install suitable imported wheels on the legendary car.
As an option when choosing new wheels for the UAZ Bukhanka, you can use BF Goodrich 33×10.5 R15 tires, and, accordingly, wheels with a diameter of 15 centimeters. As for the choice of discs for them, it depends on the wishes of the owner. These can be alloy or cast wheels. Or you can leave the regular standard wheels.
However, you should not stop at this stage, because such tuning makes it difficult to control, since on sharp turns the front wheels catch the edges of the steering rods, and when the effect of crossing the axles appears, the wheels are located directly on the sides of the arches. This causes friction between the tires and the fender. Therefore, an indispensable stage of tuning after installing the wheels is the UAZ Bukhanka body lift.

UAZ Bukhanka body lift
No matter how strange it may seem, the UAZ Bukhanka frame is attached to the body using ten furniture bolts, six of which are located in the area of the passenger seats, two behind the front wheel arches, and two more at the feet of the driver and passenger. The bolts are secured at the bottom with second nuts.
Before proceeding with the removal of the bolts, it is necessary to disconnect the battery, disconnect the ground from the engine - behind the hood compartment and raise the car on a lift.
Next, in order, we carry out the following steps:
- Disconnect the wires from the starter;
- Disconnect the radiator mounts from the bottom or top;
- We unfasten the transmission lever drive rods and the brake booster rod;
- Drain all the coolant and remove the hoses that are connected to the UAZ Bukhanka heaters;
- Disconnect the brake pedal linkage to the vacuum booster;
- Disconnect the tube leading to the tank control valve.
The last point may not seem so important, but failure to comply with it can lead to the plate bending under the fastener, as a result of which it will have to be leveled.
Next, we proceed directly to unscrewing the nuts. You should start with the six rear body bolts, then slightly loosen the front bolt nuts.
When lifting a UAZ Bukhanka with your own hands, be careful and careful, since the fasteners on such a car are usually rusty and outdated. If the bolt turns in the body, it will not be possible to hold it. This creates additional difficulties in welding a nut or bolt to it.
To do everything correctly, you need to hold one nut with a wrench, while unscrewing the locknut with your head, and only after that the main nut.
Next, you should lower the car onto its wheels, since there will no longer be a need to perform work under it. We also disconnect the steering column and unfasten the boot on the floor. And you can start lifting the body over the frame. The lifting must begin from the back of the Loaf. The lifting height should ultimately be about 10 centimeters.
It would be a good idea to secure it by placing a wide wooden beam between the frame and the body.
We unscrew the standard bolts and increase the holes for them to 12 mm by drilling. Next you need to do some work with the spacers. An inexpensive and suitable option for spacers are ordinary hockey pucks. The next steps will be to insert spacers, bolts and tighten nuts gradually, starting from the rear of the body, continuing in the middle and ending at the front.
As a result, the body will rise by 6.5 centimeters. All that remains is to secure everything and you can install large wheels.
UAZ elevator: characteristics, options
In order to increase the vehicle's cross-country ability, the right solution is to install wheels with a larger diameter. At the same time, the clearance increases. And the greater the distance between the road and the bottom point of the car, the better the car’s passing qualities.
In order to significantly increase the diameter of the wheels, modifications to the car will be required. Otherwise, the wheels either will not fit into the arches, or at the moment of turning and during certain irregularities they will cling to the body. To avoid these problems, it is necessary to lift the UAZ.
Lifting a UAZ involves a set of changes that must be made to the design of the vehicle in order to make it possible to install wheels of larger diameter. Many argue that a lift can increase a car's ground clearance. But this opinion is wrong. A clear understanding is necessary that increasing ground clearance is only possible by installing wheels of larger diameter, and the UAZ elevator is a help in this endeavor.
Set of stands for body lift “loaves”
The UAZ elevator can be of two options.
- Bodylift. Possible for frame cars. In this case, the body is lifted above the frame using spacers. This is the simplest type of lifting. In this case, the car will not need further modifications.
- Suspension lift. It is done both on framed (possibly combined with a body lift) and on frameless cars. In this case, longer springs or spacers are installed under the standard springs. The advantage of this method is that parts located underneath the car are lifted above the road. This results in a reduced risk of possible damage.
Suspension lift UAZ Bukhanka
Pros and cons of a suspension lift
Now let's look at the next way to carry out a UAZ Bukhanka lift - a suspension lift. As already mentioned, this method has both pros and cons. There are two main advantages of the suspension lift on the UAZ:
- improvement in the cross-country ability of the Loaf, ensured by the fact that the wheels remain in place, and the other part rises up;
- the ability to install large wheels, which before the suspension lift did not fit into the arches of the UAZ.
Well, the main disadvantage of this method is the inevitable increase in the angles of the universal joints. In this case, the cardans are put into operation for wear.
There are several options for carrying out a suspension lift. Let's look at some of them.
Installing longer spring shackles
The simplest and most affordable option is to install longer spring shackles. When carrying out a suspension lift in this way, you should not get too carried away with it, so as not to install too long ones. Spring shackles that are too long can negatively affect the performance of the suspension and affect handling. To avoid problems with handling, it is recommended to tighten the earrings with a tie in the center.
Bridge-spring spacer
Without disturbing the design of the springs, it is possible to slightly raise the Bukhanka’s suspension by installing a spacer between the bridge and the spring. At the same time, you don’t have to wait for a big elevator; here it is also recommended not to get carried away with the process.
Of course, when installing such a spacer, it is necessary to decide on its fixation in the installation location, and also to calculate that the length of the spring ladders is sufficient. It is also possible to restore old springs, or purchase new ones. There are also special elements for such tuning on sale, but they are usually very expensive.

Spring preload
Springing springs is not as complicated as it might seem at first glance. This process is useful not only for the sake of a suspension lift, but also for the purpose of making the UAZ’s hard suspension soft enough. However, despite the fact that there is an improvement in the performance of the suspension from this method, they are very insignificant.
If you decide to give it a try, you'll first need to cut, grind, or buy spacers, rubber, conveyor belt, and metal. And most importantly, when lifting the UAZ suspension, longer-stroke shock absorbers will be required, since the rebound of the old ones will begin earlier.
In conclusion, I would like to note that the main thing is to know moderation in everything. When you take on tuning the UAZ 452 with your own hands, remember about your safety. After all, you will not have a guarantee if you do the Loaf lift yourself.
Suspension lift options for UAZ-452
Lifting options that make it possible to raise the “loaf” suspension:
- Small elevator. If it is necessary to raise the car to a small height, it is enough to install additional leaf springs, or lengthen the spring earrings.
- Medium and large elevator. When performing a medium and high lift, we install a spacer between the bridge and the spring, or if this method is not suitable, then we install spacers on the spring mounting brackets. The advantage of lifting the suspension is that we have the ability to adjust the height and the fact that we still have original spare parts.
