The next malfunction is damage to the stem, oil seals, valves inside the rack. There are a number of spare parts on the market for repairing collapsible shock absorbers.In addition, an experienced motorist never throws away old spare parts, but tries to repair them. In addition, you can always extract workable parts from them.
Tip: The entire process of disassembling the shock absorber should be photographed. This will avoid assembly problems.
It is important to ensure that the assembly is clean, the ingress of dirt or solid metal particles will quickly damage the remanufactured shock absorber.
After pumping oil, the rack needs to be pumped, as usual.

DIY shock absorber repair video
An automobile shock absorber is a device that absorbs vibrations or various shocks passing from the roadway to the body. Such vibrations of various systems are suppressed by pistons operating in viscous media. Thanks to such media, the vibration amplitude is reduced.
Modern motorists are often faced with a complete failure or breakdown of the suspension system, the main parts of which are shock absorbers. Therefore, urgent repairs are required, which will save the car owner from further complications. Such repairs should begin with a detailed diagnosis.
Shock absorbers are rear and front. In order to repair such critical parts, a detailed knowledge of the structure itself is required.
A modern shock absorber is a complex device consisting of different parts. Shock absorbers are replaced exclusively in pairs. In case of damage or breakdown of one rack, the car owner will have to change both. In the process of restoration or when repairing the shock absorber, you must use the vehicle operating manual. A detected malfunction requires careful study and appropriate solutions.
The process of repairing a shock absorber must be prepared accordingly. This will require the following tools and materials:
car kit;
screeds;
support goats;
rack key;
new cartridge.
After preparing the listed devices, you can start directly repair work.
The current safety regulations require the vehicle to be installed on pre-prepared trestles. In this case, it is necessary to set them correctly. The fastening bolts of the lever and the stem nut are unscrewed, then the fasteners are removed and the shock absorber is removed. Removing the shock absorber is quite easy if the fasteners are unscrewed correctly, but you must not forget to remove the internal thread.
After completing the dismantling of the shock absorber, you can remove the internal parts from it. First, the old cartridge is removed, in place of which a new one is installed and tightened with a nut. By replacing the cartridge, you can return the shock absorber to its place using the described steps.
After completing the repair, the vehicle should be sent to a service center to carry out the alignment of the camber-toe system. Experts also advise, when repairing or restoring shock absorbers, to diagnose and check the main elements of the car suspension, including the steering rod, brake hoses, rails, blocks.
Just like any product or part, shock absorbers have their own operational and replacement periods. Restoration or repair of the device should be carried out immediately after the discovery of a breakdown and malfunction. As for their complete replacement, it is performed every three years.
To increase the operational life, the following simple rules are recommended:
refuse to use the delivery for lifting the suspension, which can damage the shock absorber rod;
avoid high speeds when driving on damaged roads;
in winter, preheat the oil in the shock absorbers.
If you decide to raise the car body, you need to take care of installing shock absorbers of the appropriate size. Awkward handling can cause rapid wear on not only the shock absorbers, but the entire suspension as well. And in winter, to start driving, you must use a low speed and low gears.
If all the above operating rules are observed, timely diagnostics, as well as repair or restoration of shock absorbers, a significant increase in the service life of the entire vehicle is possible. Repair work is carried out in accordance with the nature of the detected malfunction. Do not forget about innovative non-collapsible shock absorbers that cannot be repaired.
Every experienced motorist is familiar with the typical malfunctions of this unit. If oil leaks, this indicates a depressurization of the stem oil seal, which can cause a complete loss of performance of the part.
You should also be wary if there is a backlash during rebound or compression. The consequences will be the same as with broken valves. The device will no longer be able to perform its direct functions, and the car will emit knocks, rumblings and other unpleasant sounds while driving. Driving in such a car is not only uncomfortable, but also quite dangerous.
Of the external damage, cracks in the lugs or dents on the housings can be distinguished. Such minor problems can lead to more serious damage and even affect the chassis. Upon finding any sign of a similar breakdown, the rack is removed and released from the spring.
The best way to detect shock absorber problems is to check the stability of the vehicle itself, both at high and low speeds. The owner should pay attention to how his "iron horse" reacts to bumps or holes and how quickly it restores balance when hitting such irregularities.
If even the slightest deviations are found, it is necessary to view the shock absorbers in detail. Analyzing the state of protection, you should inspect the anthers. For such purposes, flyovers or special pits are used, allowing you to inspect both the front and rear shock absorbers from below.
If the anthers are torn or even slightly damaged, it is better to install a new protector. It is the anthers that are responsible for protecting the shock absorbers from small particles of dirt in the holes, which over time leads to all sorts of breakdowns or damage. If the shock absorber lacks this protection, its service life is significantly reduced.
Taking into account the main function of shock absorbers - to reduce the rolling of the machine on uneven road surfaces, it is quite easy to determine the malfunction. The main sign of failure of this device is an increase in vibrations and the appearance of unnecessary noise that was not felt before.
If the wheels of the car fall into the hole, then you can hear the sound of punching, which is also considered an additional sign of breakdown. So you can find out about the need for an early replacement or repair of shock absorbers. However, a more detailed study of the problem will be required.
First, you need a visual inspection of the part and its careful study. If an oily leak is found, it is imperative to carry out repairs and return the shock absorber to working condition. It should be noted that the process of diagnosing this device at the stand is a rather difficult task, so many try to immediately purchase new shock absorbers or repair struts using a repair kit on their own.
The shock absorber is considered to be a consumable item, which must be changed after a three-year period. The bad condition of Russian highways reduces this time by several times - the suspension breaks down much earlier than the period specified by the manufacturer. However, you should not despair in advance, as well as throw away the broken part. If the shock absorber cannot be repaired, it can always be replaced.
Before choosing a method, it is necessary to take into account several factors, including the cost of a new part - if it costs the car owner as much as the repair, you should not get your hands dirty. In addition, repairs require certain skills. Also, remember that a remanufactured shock absorber will not last long.
In general, a shock absorber is a multifunctional part that is responsible not only for damping body vibrations, but also for braking. It ensures the stability of the vehicle. Therefore, having well understood the essence of the operation of such a device, the driver will be able to understand the problem in time and make the right decisions to eliminate it. Even after going through MOT, the shock absorbers can suddenly creak or leak, so you need to monitor them constantly.
Most modern cars are equipped with so-called non-separable shock absorbers. This means they cannot be repaired. Unlike collapsible counterparts, they have a five-year warranty period. And on high-quality highways, they will last even more.
There are also pumped shock absorbers. For such models, the gas backpressure has been changed, which performs a restructuring of operational characteristics if the car is subjected to heavy loads. They work perfectly up to breakdown, performing the additional option described above. If such a shock absorber breaks down, it will be quite difficult to repair it.
The fact is that models with pumping during repairs overlap the hydraulic fluid pipes, which are responsible for the health of the entire part. It is almost impossible to carry out such repairs without the intervention of specialists and special equipment. And the purchase of a new part will cost several hundred dollars.
Experts recommend using only original components for repairs and not trusting cheap fakes - after all, the coherence of the system and machine components depends on this device. We must not forget that insurers, when an appropriate case occurs, intervene in each verification procedure, studying all the details in order to find the reason and, if possible, refuse to pay.

The correct operation of the shock absorbers is no less important in terms of the safety and durability of the car than a well-functioning motor or brake, steering system. For example, if a car moves on a rough road, one of the wheels breaks off and the vehicle loses control for a split second. Attempts to brake or twist the steering wheel at speed are fraught with rollover. Shock absorbers just reduce the time of separation from the road surface. Therefore, their failure leads to accelerated wear of the body, and even an accident. Is it possible to repair shock absorber struts with your own hands? More on this below.
By design, this device resembles a chamber with a liquid or compressed gas inside. Through them the piston with holes moves. When its stroke is small, the chamber is filled by means of bypass valves. In this case, the shock absorber does not affect the suspension operation in any way.But as soon as an obstacle is detected in the form of a hole, for example, a force appears that slowly pulls the rod up. Moreover, its value is the greater, the higher the speed. As a result, after overcoming unevenness by inertia, the shock absorber still holds the wheel in a "suspended" state and the driver and passengers almost do not feel the suspension failure. When hitting a bump, the stock begins to sink quickly, and after passing the obstacle, it slowly returns to its place.
If the suspension is simple (dependent or double wishbone), typical of the Soviet "classics", then just sharply press the wing with your hand and release it in order to swing the body 10-15 cm. If it swings no more than two times, then the test is passed. If not, you will have to change the shock absorber, or even the entire rack (for front-wheel drive cars).
However, for cars with a multi-link suspension, such a "number" will not work: it's all about the silent blocks that damp vibrations. Here you need to contact the technical center where there is a stand to check the device. You can do this yourself, but the result will not be accurate, since instruments are needed to measure the force of impact on the product. Remove the suspension element and pull it out by the rod, and then press it in. The tensile force should be significantly greater.
It is recommended to carry it out on a lift or inspection pit. As a last resort, use a jack and stands. Be sure to use supports and wheel chocks: the slightest displacement of the car is fraught with injuries for the repairer.
On a front-wheel drive car (for example, VAZ2109), you will have to remove the rack. To do this, disconnect it from the steering tip and the steering knuckle at the bottom (do not forget to move the brake hose). Then tighten the springs with a special tool and unscrew the stem fastening nuts, holding it with an asterisk wrench. Then unscrew the three nuts from the top in the engine compartment and pull out the rack. At the same time, inspect the support bearing - it may need to be replaced. If the car is rear-wheel drive (for example, a VAZ classic), everything is simpler: you need to unscrew the bottom two nuts securing the product to the triangular arm, and from the top - one (you need a “7” key to hold the rod) - the shock absorber will fall down.
It can have a variety of design features, however, the shock absorbers are mounted in two ways:
bolt from below and from above through the silent blocks;
a bolt with rubber grommets at the bottom and top - a pillow with 3-4 of the same hardware. In this case, you can get to the shock absorber mount from the trunk or the passenger compartment.
First, the dismantled device must be washed, then carefully inspected. If there are cracks, jams, repairing the shock absorber does not make sense: it is better to send it to the scrap and buy a new one. The whole body requires further inspection: pull the stem up and push it down - if there is play, sticking, replace the part. The shock absorber is of two types, the disassembly of each of them has its own characteristics:
two-pipe: pull the stem completely out to gain access to the fastening nut, which is unscrewed with a special wrench;
one-pipe: there is a protective cap at the top, which must be knocked down and then unscrewed the fixing nut to get the stem together with the cylinder or the cartridge.
If the shock absorber is oil, it is necessary to drain the oil from the cylinder, for which press the valve spring. Then knock down the bushing, take out the rod with the piston, remove the valve from the other side of the cylinder. If the device is gas or with a replaceable cartridge, simply unscrew the fixing nut and put in a new one.
There are two ways: the first is to completely replace the rod together with the cylinder with a new cartridge, the second involves replacing the device parts. It is worth dwelling here in more detail, because in the first case, the financial costs will be 5-10 times more (it all depends on the car model) more.For self-restoration of the shock absorber with complete disassembly, you must purchase a repair kit.
If you have a foreign car after 2000, then it is very difficult to find such a set - it is easier to buy a new shock absorber.
To disassemble the product, unscrew the fastening nut and pull out the piston. Further:
replace the squeeze valve, which is installed by hand pressing;
put the piston and guide sleeve;
fill in oil (you can use the old one if it is clean and transparent) - hydraulic fluid for automatic transmission, power steering, or the Russian agent AZH-12T.
Liquids produced in the West have no advantages over materials from the Russian Federation.
Press the rod into the cylinder and fill with 200-250 ml liquid. Then slowly insert the cylinder while pulling out the rod so that the oil penetrates into the cavity and does not flow out. When the cylinder is fully inserted, pull out and reinsert the stem several times: this will allow the oil to completely fill the housing. Then tighten the nut and pump the shock absorber again 4-5 times.
On a two-pipe device, all of the above restoration procedures must be carried out with the upper pipe on the lower one. Press it down during the process while holding the stem in place. Next, you need to pump the device and tighten the nut.
If the shock absorbers were restored on a McPherson-type front suspension, then the camber and toe-in would have to be adjusted.
All operations to restore performance are no different from those described above. But before installation, the shock absorbers must be well pumped (this also applies to new products), otherwise they will not work fully. How to do it?
put the device with the stem down and press the stem until it stops;
hold the shock absorber in this position for a couple of seconds;
without releasing the rod, turn the part over and hold it in a compressed position for 5-6 seconds to let the air out;
extend the stem completely, pause for 2-3 seconds and repeat the operation 5-6 times.
VIDEO turn the product upside down;
slowly press in the rod and leave the part in this position for 5-6 seconds;
turn the product over and stand for 5-6 seconds;
extend the stem until it stops;
flip the shock absorber over and repeat the procedure 3-4 times.

It is necessary to follow simple rules, then these devices will last much longer than even their manufacturers claim:
the driving speed should correspond to the road surface: you should not accelerate on an uneven, bumpy and bumpy dirt road, even if you are driving an SUV.
Check the condition of the shock absorbers every year: fluid leakage from them indicates the need for immediate diagnosis.
If the shock absorbers are replaced (they must be the same), then this must be done on the wheels of the same axle.
When driving in cold weather, after warming up the engine, drive at a slow speed for at least 5 minutes. During this time, the oil in the shock absorbers will warm up, and they will begin to work normally.
If you have new shock absorbers in stock, they must be stored vertically (as required by the manufacturer): the stem must be pushed in. For gas products, it can be pulled out spontaneously, therefore it is necessary to use special screeds. It is worth adding: if the shock absorber is oil and it is expected to have a long shelf life, then it is better to use a horizontal position so that the oil seals are lubricated with liquid and do not dry out.
It is necessary to make a decision on how to proceed further only after the species and the reason for its failure have been studied in detail.
It is quite possible to restore each type of shock absorbers on your own.The difficulty will be in determining how deplorable his condition is and whether it makes sense to restore it.
By and large, only repairable racks can be reanimated. If the rack has worked a fairly large mileage of more than fifty thousand, and its condition is very deplorable, then such a rack is not something to repair, it is strictly forbidden to operate it in the future. Better to play it safe and buy a new part.
If you listen to the opinion of experts, then we can conclude that repairing shock absorbers is not an option to save money. Given the fact that this device performs a large amount of work, repairs will only delay its complete wear. Therefore, it is necessary to make a decision on restoration or complete replacement after the first breakdown.
So, before the repair, it is necessary to carry out certain activities - you need to prepare the tool.
Special kit for the restoration of old shock absorbers
New stock
Special cleaner for electric motors
Rack oil
Brush (you can use an old brush to clean your teeth)
Knife (preferably sharp)
In this particular case, I will tell you how to get rid of such a malfunction as an oil leak. This is one of the main reasons why the device wears out quickly, which means it loses its performance.
So, let's look at the stages of recovery:
If you have any problems with the racks, then they must be solved without delay. Of course, it is better to replace them with new ones. Good luck.
After watching the entry, you will find out how you can pump the shock absorber of your car at home and what tools you need to prepare for this.
VIDEO Almost every motorist can repair shock absorber struts, if he is not afraid of dirty work under the car. At the same time, you will be able to save a good amount of money. After all, as soon as dull bumps begin to appear in the suspension of the car when driving through pits and potholes, then it’s time to come to grips with repairing shock absorbers.
Each automaker uses its own design developments to damp vibrations when the vehicle is moving. But shock absorbers are present in almost all modern cars.
The lifespan of a shock absorber is determined by the driving style and the quality of the roads. For example, many 10-year-old cars from Europe with a mileage of more than 200 thousand km come to us on "native" shock absorbers. And in our road conditions, a rare suspension part survives up to 100 thousand kilometers.
At the end of this article you will find a visual video tutorial on repairing the shock absorber strut of a VAZ 2110 car.
Below we will talk about what are the main malfunctions of shock absorbers, and how you can fix them with your own hands, if you have certain skills, tools and the desire to do this.
The main malfunctions of shock absorber struts are:
Free movement of the rod in the cylinder,
The presence of knocking when compressing or stretching,
Oil drips.
Finding all these problems is quite simple, even without removing the shock absorbers from the car.
To determine the performance of the shock absorbers, it is necessary to press hard several times with the whole body weight on the wing or bumper of the car directly above each shock absorber in turn. If, after the car stops rocking, further vertical vibrations occur, then the shock absorber is faulty. Usually, a working node stops swinging immediately after the impact on it stops.
In a similar way, knocks in the shock absorber strut are detected. To do this, rest your hand with the palm of your hand at the top attachment point of the rack and swing it up and down with sharp rhythmic presses. Impacts will be clearly felt upon contact.
To find leaks in the shock absorbers, it is enough to look between the wheel and the arch of the car. Turning the wheel to one side will help to improve visibility. It is even more convenient for these purposes to use a viewing pit, overpass or lift.
For more information on methods for checking the health of car shock absorbers, read our article on how to check shock absorbers on a car.
Repair of shock absorber struts begins with their dismantling. Removing the shock absorbers is usually not a problem. Unless the fasteners force the motorist to swear loudly and resort to drastic measures ("grinder" or gas "cutter").
But more often than not, it is enough to clean the nuts and bolts from sand and dirt, and then treat them with WD-40 fluid. After 20-30 minutes, you can start dismantling.
Here are a few things to consider when removing shock absorbers for later repair or replacement:
Often, the part of the car where the shock absorber is removed has to be hung with a jack. It is imperative to install stops under the sill or bottom so that the car does not accidentally move during repairs.
For better access to the lower mountings of the shock absorber, the corresponding wheel must be removed.
The upper attachment points of the struts in most cars are usually located under the hood and in the trunk.
In front-wheel drive vehicles, removing the strut requires more work. The complexity of the work depends on the type of shock absorber.
Collapsible shock absorber structures are distinguished by more complex rack dismantling. To remove such a unit, you will have to unscrew the hub nut and remove the rack together with the hub.
Non-collapsible shock absorbers have a simpler strut design. At the lowest point, the shock absorber is inserted into the cup, where it is attached with one or two bolts.
The top attachment for both types of struts is usually located under the hood (front shock absorbers) and in the trunk (rear). Here you will need to tighten only two nuts.
The shock absorber struts in front-wheel drive vehicles are usually removed with the springs.
To determine the cause of a front wheel drive vehicle's shock absorber strut malfunction, it will most likely have to be completely disassembled. For details on disassembling, assembling and repairing a shock absorber, see the video tutorial at the end of this article.
Ties will be an indispensable tool for disassembling the shock absorber. This spring compressor is a heavy duty stud with a left-hand thread at one end and a right-hand thread at the other. There is a turnkey hexagon at the end of the stud. Grips (with left and right threads, respectively) are screwed onto the ends of the hairpin, which will reliably cling to the coils of the shock absorber spring when it is compressed.
Two such clamping devices are required to compress the spring. They are installed on opposite sides of the spring. Pulling is done by alternating rotation of the pins.
When the spring is compressed enough that it becomes free to "walk" in the rack, you can unscrew the top nut, remove the support bearing with a rubber bumper, and carefully remove the spring.
After careful inspection, it may turn out that the cause of the knock lies in a worn rubber bump stop.A tight rotation with a creak is observed when the support bearing fails.
The collapsible shock absorber is unscrewed from the body using a special key. Some motorists do this job successfully with a hammer and a suitable steel bar.
After replacing defective parts, the shock absorber strut should be reassembled in reverse order.
When the top nut is securely tightened, the spring must be slowly released to a working condition. It is important that the first turns fall into their slots, which prevent it from shifting.
After that, it remains to install the shock absorber strut in place, screw the wheel and lower the car.
Damper struts should be repaired without haste and in compliance with safety regulations. Especially carefully and carefully it is necessary to compress and unclench the springs. Then the repair will take place without damage to the car and human injury. And the car after the repair of the shock absorber struts will go smoothly and quietly.

What part of the car do you think suffers the most on our roads? Of course, this is the chassis. The wear of its elements is happening faster than we would like. And one of the most common problems is the failure of shock-absorbing struts. Sometimes the matter can be corrected with timely repairs, and sometimes a complete replacement of the shock absorber strut is required. We will deal with both the first case and the second. But first you need to decide what this element is
Due to the fact that the shock absorber struts are the most "delicate" element of this system, we will pay full attention to them. Front (sometimes rear) shock absorber struts are made according to the principle of a double-acting shock absorber operating on hydraulics. The rear shock absorber strut is most often manufactured according to the standard two-tube design. It is not worth delving into the structure of these elements, but you still need to know the main differences between them.
So, the main difference in the shock struts is that the front struts primarily affect the handling of the car, while the rear ones serve to increase comfort. The idea is clear - the front struts should be in working order, but you shouldn't forget about the rear ones either, because the good condition of the suspension means trouble-free and comfortable movement of the car.
Diagnostics of suspension struts
But how do you check the condition? The vehicle owner can carry out diagnostics, while the process itself is not difficult. The more modern the vehicle is, the easier it is to inspect and evaluate. But there are general signs that apply to all cars: If you notice fluid leaks in the suspension area or hear a constant knocking while driving, then with a probability of 95% the struts need to be repaired. Moreover, the repair of the racks can be done by hand.
So, we have identified a malfunction - repair is required. Of course, you can go straight to the car service, where you will be replaced or repaired, but you need to say right away - it is quite expensive. Another option is to do the work yourself. If your car has collapsible struts, then there should be no problems with the repair. Unfortunately, in modern foreign cars there are most often solid racks, but in domestic and old cars, the racks are collapsible. Why is that? In Europe, repair is a replacement for quite a long time. And it is right.
In the cold season, it is worth warming up the shock absorbers in the same way as the tires: after a night of inactivity, the car needs to be driven for about five minutes at low speed. This is done so that the oil warms up quietly. If gas is added immediately, the frozen oil can break the poppet valves.
Non-dismountable shock-absorbing struts
If you are the owner of a car where non-collapsible racks are installed, then you will not be able to cope with your own hands - special equipment is required to maintain them, so there is only one way out - to go to a car service. Almost every workshop offers maintenance services for non-collapsible racks. Here lit is better to choose a proven and recommended car service, because the repair of such racks is the introduction of structural changes. There is a chance that they will fail again after repair, even if it is carried out by experienced mechanics, so replacement will be more profitable and more reliable.
Before you start repairing racks, you should decide on the tools:
Do-it-yourself repair and replacement of racks is a change in the main part of the rack - the cartridge, so you need to purchase it. When buying, you need to name the model of your car.
You will need a rack wrench for front-wheel drive cars (you will need it for springs and ties) and a classic one.
Goats must be placed under the car, it is strictly forbidden to work with a jack, because this threatens the safety of the person carrying out the repairs.
Shock Absorber Repair Tools
So, you will be able to independently assess what type of struts is installed in your shock absorber. To do this, a simple inspection is enough for you. If there are fasteners, various nuts, bolts, then the rack can be disassembled. If it is a one-piece product, then the solution to the problem on its own is canceled. Well, now let's move on to the step-by-step instructions:
Remember: repair of shock absorber struts can only be paired.
Get your tools ready, you won't need a lot of them. Also bring a bowl of water and rags, as we will need to wipe the oil drips.
Now you need to put the car on a jack.
On the classics, dismantling the rack is quite easy, but with front-wheel drive cars you will have to tinker: the spring must be evenly compressed with ties on both sides. The compressed spring will then need to be rearranged to a new rack, but before that, a visual defect should be carried out.
Work begins with the rack: we carry out dismantling, then we drain all the oil. After that, you need to take out the "filling" in the scrap and put a new cartridge in its place.
The main process is completed, now you can assemble the system in the reverse order: the spring, then the support bearing and the stand itself on the machine.
After the completion of the repair, it is imperative to carry out a similar collapse. It would be better to contact the service station with this operation.
The rear pillar is repaired in the same way. Do not forget that you need to carry out repairs exclusively in pairs.
Repair of shock absorbers
Of course, repairing shock absorbers will be much cheaper than replacing them, but sometimes you have to do that too. Again, you can diagnose and see if they can still last after being repaired. If you are not sure of your discernment, then the diagnosis can be carried out at a car service. If you change shock absorbers, then this process should also be carried out only in pairs. To replace, you will need the same tools: a rack wrench for the classic and spring-loaded ties for front-wheel drive vehicles.
Do not test the strength of your shock absorbers on a bad road - this can keep them in good condition for a long time. High speed also negatively affects them, so if you drive, then on a high-quality road surface. Lifting the suspension also harms the entire shock absorber system: the rod begins to function in the area of movement, and this entails a quick failure.
If replacing the shock absorber strut can be done by hand, then replacing the entire shock absorber is most often done in a car service, because this is an overly responsible event. Finally, we would like to give a few recommendations on the care of new shock absorbers. The first step is to carry out anti-corrosion treatment of the bottom of the car.This will help you cope with adverse weather conditions.
Means for treating cars from corrosion
Again, this is necessary for our realities, since bad weather lasts about six months, and you rarely see gutters on our roads. Therefore, when you move through solid puddles, it is simply necessary that the underbody of the car is protected from corrosion. In addition, we recommend that when repairing shock absorbers, pay attention to the rear axle gearbox, as well as to other elements of the car's suspension.
