Body diagnostics

The body is one of the most expensive and vulnerable parts of the car. It reliably protects the internal mechanisms and ensures the safety of the driver and passengers.

A car just released from the factory has a clear, symmetrical body geometry. As the car is used, the parts that form the frame of the car gradually wear out, and the fastening between them begins to shift. This leads to the risk of mechanical damage to the car as a result of an accident due to poor controllability of the car. To avoid such an outcome, it is recommended to periodically check the geometry of the car body.

Why analyze the car frame

A comprehensive analysis allows you to get reliable information about the condition of the car and identify even minor defects.

During the process of measuring the geometry of the body, the following parameters of the car are checked:

• width of the front and rear track;
• axle distance of the wheels;
• length of the side members and the distance between them;
• diagonals in the openings of windows, doors, in the engine compartment, trunk and cabin.

The geometry of the body determines not only the appearance of the car, but also many important driving indicators of the vehicle.

In what cases is it necessary to conduct a diagnostics of the body condition?

✅ Firstly, the body should be checked for damage periodically for preventive purposes, in order to avoid major da

mage.

✅ Secondly, a thorough inspection is required when preparing to buy/sell a car.

Engineers will inspect the condition of the car as a whole and each individual unit. They will draw conclusions and provide confirming photo or video reports in electronic form.

For the seller and the buyer, body diagnostics differ in a number of characteristics.

Pre-sale car diagnostics service

If you are a seller, we will prepare the following documents for you: “Letter of external body damage” and “Diagnostics of the interior condition”.

As a result, you receive information about:

1. external visual inspection of the body, search for scratches, chips, dents, cracks in the windshield.
2. visual inspection of the interior, search for abrasions, cracks, burns, stains.
3. external assessment of the body condition by an inspector with a mark on a certain scale.

The suspended parts of the body undergo a thorough check: fenders, hood, doors, glass and headlights. All gaps, joints, welds, markings and side members will be marked, since these are the factors that form the quality of the external parts of the body.

Body diagnostics will be a reasonable precaution, since it will allow you to avoid unplanned costs in the future. You exclude the possibility of unpleasant surprises that could appear after the purchase, because the specialists of the MB Master car service use professional equipment and have tested hundreds of cars.

What is body geometry

Body geometry is a parameter whose distortion occurs as a result of an accident. Both as a result of a serious event, and in the case of an elementary wheel running onto a curb, a slight bumper hit or ordinary off-road driving. The specialists of the MB Master car service advise you to undergo regular body inspections. You need to start (and do it systematically) with checking the wheel alignment.

But even the absence of problems with the wheel alignment is not a guarantee of the absence of problems with the geometry of the car body. The body is checked on specialized stands and frames.

Here, at checkpoints, with the help of special equipment, everything is measured:

1. the diagonals of the side members in three dimensions,
2. the openings of the engine and luggage compartments
3. the openings of the doors and windows, the front glass
4. the distances between the checkpoints in the side members, the supporting parts of the bottom, etc.
5. we will also be able to see damaged areas that require urgent protection from corrosion.

Stages of restoring the geometry of the body at the MB Master service station

Diagnostics

At this stage, our specialists test the geometry of the body using a special measuring system. Professional equipment allows you to determine the smallest deviations in the geometry of the body in comparison with the factory production standards of a certain car model.

Restoration

The next stage of work is to correct the geometry of the body. Restoration is carried out using a frame stand, or, as people call it, autowork. The frame stand allows you to correct damage of any degree of complexity and restore the original shape of the car. The result of this procedure is a guaranteed restoration of the standard geometric shape

Repeated diagnostics

After the main stage of work, repeated diagnostics are carried out to check the results of the restoration of the body geometry. Any inaccuracies or shortcomings made during the main stage of work will be found and corrected additionally. Thus, the final quality of the restoration work is impeccable.
