Car shock absorbers dampen vibrations and absorb shocks and shocks that occur when driving on uneven roads. This ensures comfort and improves wheel grip on the road surface.

Shock absorbers convert the mechanical vibration energy of units connected by elastic elements (torsion bars and springs) into heat. The condition of these parts determines the vehicle's handling and braking distance.

The factory equipment of the Chevrolet Niva provides for the use of products from the Skopinsky Automotive Assembly Plant (SAAZ). Oil shock absorbers from this plant demonstrate good performance characteristics with a calm driving style. Their main advantage is their affordable price. Also for the Chevrolet Niva, gas-oil shock absorbers are produced, in which, in addition to oil, inert gas is pumped. They work out vibrations faster and press the wheels better on the road when cornering and driving along “ridges”.

For drivers who prefer a measured driving style, we can recommend the oil type. They cost 25-30% less than gas-oil ones and provide comfortable and safe driving under normal conditions. Statements about the shorter service life of oil-based devices are not true. Two-pipe oil-filled structures are more difficult to damage, and they remain operational even with partial leakage of the working fluid. Therefore, installing them is a way to save money.

Gas-oil shock absorbers for auto tuning are characterized by increased rebound and compression forces. This makes the suspension stiffer, but the car becomes more stable when cornering at high speed or driving on a washboard. Fans of sporty driving sacrifice comfort, but gain confidence that the shock absorber will cope with the load when driving fast on uneven roads. The gas maintains high pressure of the working fluid and prevents the formation of foam.

Compatible parts are produced by dozens of manufacturers from Russia, Europe, America and China. Let's look at the three most common brands.

1. SAAZ (Skopinsky Automotive Aggregate Plant) is a company that was founded on the basis of an enterprise of the same name. Since the 50s of the last century, the company has been supplying auto parts for VAZ, GAZ and other domestic cars. The products of this company are in high demand, since many Shniv owners try to save money, and the quality of the parts is at an acceptable level.

2. SS20 (Technology System) is another Russian company founded in 1993. This Samara enterprise specializes in the manufacture of steering and suspension parts for Russian cars. Spare parts in the mid-price range are more reliable than SAAZ budget products.

3. KAYABA (Kayaba) is a Japanese company considered one of the best manufacturers of shock absorbers. The price of oil models is slightly different from SS20 products. Expensive gas-filled shock absorbers are specially designed to perform in harsh conditions. They help keep the car on sharp turns and on uneven roads. The quality of the brand is confirmed by the fact that KYB parts are installed on rally cars.

Shock absorbers are an integral part of a car’s suspension, the effective operation of which determines not only a comfortable ride, but also traffic safety. At the dawn of the development of the automotive industry, cars were equipped with springs, which made it possible not only to soften road unevenness, but also to dampen vehicle vibrations, keeping it from swaying.

Technological progress has implemented new design solutions that separated the mechanisms of damping and mitigation of dynamic loads. This is how two new units appeared: a spring and a shock absorber. The latter not only creates comfortable driving conditions, but also prevents the car from swaying, ensuring reliable contact with the road, especially when turning.

Shock absorbers with regressive characteristics develop significant forces at a low speed of piston movement in the initial stage of movement. As the speed of its movement increases, the resistance force grows much more slowly. Thus, the regressive characteristics allow you to hold the car well in turns, preventing the car from lateral roll, and also keep the car from longitudinal nods during sharp braking.

However, regressive shock absorbers are very sensitive to unevenness, potholes and other road surface defects. Dampers with progressive characteristics have relatively little resistance at low piston speeds, but as they increase, the force increases quadratically.

Compression should provide the necessary suspension subsidence, preventing it from hitting the body bump stops and creating comfortable driving conditions. At the same time, the rebound parameters should help the wheel roll over uneven surfaces while maintaining full contact with the road. The resistance force during rebound must be significantly higher than during compression, since it is necessary to absorb kinetic energy when the body oscillates.

Almost all domestic cars have shock absorbers of a regression or linear type, which reduce the impact of shock loads on the body. Based on their design characteristics, they can be divided into single-cylinder and double-cylinder. Both of them can be hydraulic, where special types of oil are used as the working fluid. Or gas ones, in which the main damping function is performed by the gaseous medium.

Hydraulic or oil shock absorbers are the most common due to their simplicity of design and low manufacturing costs. They have regression characteristics. When driving on uneven roads, the hydraulics behave flawlessly, smoothing out vibration and rolling around bumps.

In oil shock absorbers, the rod is returned to its original position by the suspension spring, and the bumps are bypassed in full contact with the road thanks to soft regressive characteristics.

Gas-oil devices have the same design as hydraulic ones. However, inside there is nitrogen under low pressure, up to 0.5 atmospheres, which acts as a pressure accumulator and prevents aeration. Gas-oil shock absorbers significantly improve the properties of hydraulics and are increasingly used.

The design with one working cylinder is more often used in gas models, see figure.

The principle of operation of these devices is as follows: during compression, pressure occurs on the piston 3, which is transmitted through the oil medium 2 to the floating piston 4. The latter is a barrier between the gas 10, located in the housing 8 under high pressure of 15-30 atmospheres, and oil 2, transmitting the pressure from the piston.

The gas shock absorber has a progressive nature of operation, which allows you to effectively operate the car on high-speed roads under heavy loads when cornering, reducing vehicle roll. However, when driving on uneven roads, there will be increased stiffness, reducing driving comfort.

Shock absorbers for the factory equipment of the car are manufactured at the Skopinsky Automotive Assembly Plant (SAAZ for short), located in the village of Chulkovo. SAAZ oil devices are reliable during operation at a calm driving pace. Their main advantage is their relatively low cost.

This plant also produces gas-oil models, in which, in addition to oil, inert gas is pumped. Gas-oil SAAZ models are distinguished by increased combat forces. They better press the wheels to the road surface. This makes the entire suspension stiffer, so the car is more stable when driving fast and when cornering.

Front and rear shock absorbers for Chevrolet Niva: do-it-yourself selection and replacement

Chevrolet Niva owners have a question about which of the options offered on the Russian market are the best. There is no clear answer here. It all depends on the conditions in which the car is operated. Based on the requirements, they already choose a specific brand.

The cause of shock absorber malfunction can be various factors:

  • gas leak;
  • failure of silent blocks;
  • torn oil seal;
  • deformation of valve plates;
  • aging of fluid in the shock absorber.

Signs of a faulty car part on a Chevrolet Niva are easy to detect:

  • When accelerating and braking, the car “squats”.
  • when driving on an uneven surface, the suspension spring is compressed so that it reaches the limiter;
  • oil leaks on auto parts and the entire suspension;
  • drifts appear;
  • the quality of wheel adhesion to the road surface decreases;
  • The shaking inside the car increases.

Regardless of the quality of the shock absorber, as well as the operating conditions of the car, wear and tear on this part of the car occurs constantly. Therefore, regardless of the cause of the breakdown, it is recommended to immediately replace the failed device with a new one.

Before replacing a car part, you must prepare the following tools and materials:

  • metal brush with stiff bristles;
  • 2 socket wrenches with ratchet 19 x 2.

It is necessary to replace shock absorbers only comprehensively, that is, on both sides, even if only the front or rear car part is faulty.

The front suspension is considered more complex in design, so replacing the front shock absorber of a Niva Chevrolet will take more time (about 20-30 minutes) and effort, but the operating principle is the same.

Compatible parts are produced by dozens of manufacturers from Russia, Europe, America and China. Let's look at the three most common brands.

1. SAAZ (Skopinsky Automotive Aggregate Plant) is a company that was founded on the basis of an enterprise of the same name. Since the 50s of the last century, the company has been supplying auto parts for VAZ, GAZ and other domestic cars.

To replace the lower ball joint you will need the following tools:

  1. Hammer.
  2. Jack.
  3. Mount.
  4. Wire brush.
  5. Wrench for removing wheel nuts.
  6. Keys for "27", "22" and "13".

We dismantle the wheel and place a support under the lower arm, thus aligning the position of the arms and loading the suspension. Remove the hub cap and unscrew the nut. As practice shows, it is always tightened very tightly, so you should use a head with a strong knob.

We unscrew the nut screwed onto the support pin and press the pin out of the steering knuckle socket. then we unscrew the nuts of the bolts that hold the lever on the support and, retracting the steering knuckle, pull out the bolts. We remove the wheel hub from the splines of the outer drive joint shank, then dismantle the ball joint and install everything in the reverse order.

SAAZ plant

This raises the question of which of the options offered on the market are the most effective and reliable. There is no clear option; a lot depends on the conditions in which the car is operated. Based on this, they choose which variety to use.

The question also arises about manufacturers. There are quite a large number of companies on the market that produce similar parts. Their quality is approximately the same, but the price may vary. This is one of the most important factors in selection.

Device

The design of the units depends on the type of working environment. Separates mono-tube and twin-tube shock absorbers. The first type is more expensive. It is typical for gas-filled units.

A monotube shock absorber consists of a single cylinder, at the bottom of which there is a gas chamber separated from the oil by a floating piston. It compensates for changes in fluid volume and prevents the formation of oil foam at high frequency compression-extension cycles.

A piston mounted on a rod moves inside the chamber. The valve, which allows oil to pass through itself, provides rapid compression of the shock absorber, while slowing down the return of the rod to its original position.

Two-pipe oil devices have a lower price. They have lower requirements for the quality of the seal and housing material. Such shock absorbers consist of a pair of cylinders of different diameters placed inside each other. The rod piston moves through the internal (working) chamber, which is connected to the external one. When compressed and stretched, oil flows between the chambers through the bypass valve.

Front

The size of the parts depends on the year of manufacture and, in particular, on tuning. SUV owners like to raise the ground clearance to increase cross-country ability.

The standard front shock absorbers of the Niva 2123 have a length of 220 mm in the compressed position and 304 mm in the extended position. For “lifted” cars you need to select the dimensions individually. Such Nivas use parts with a maximum connecting size of 400 mm or more.

The rod of the upper part of the front shock absorber is attached to the car body, and the eye in the lower part is attached to the mounting bracket to the suspension arm.

Chevrolet Niva stabilizer, replacing it step by step

To replace the Chevrolet Niva stabilizer, remove it from the rod using keys “17” and “13”. With their help, we unscrew the four nuts securing the stabilizer brackets to the front axle gearbox, and then remove the brackets.

We remove the stabilizer and pay attention to the condition of the element. The cushions must show no signs of rubber aging, damage, or signs of wear on the internal surfaces in contact with the stabilizer. If the cushions are damaged, they should be replaced. The stabilizer is installed in the reverse order.

Rear

On cars with increased ground clearance, parts from Mitsubishi Pajero-1 can be used. The size of standard parts is 326-526 mm. They are attached to the body and lever through two eyes.

What are the best shock absorbers for the Chevrolet Niva? Traditionally, the most popular and best (according to the majority of owners of this car) are shock absorbers from the Japanese company Kayaba (KYB). These are oil struts with a gas pan. Traditionally, Kayaba shock absorbers strike a balance between comfort and vehicle handling. Compared to standard ones, it is a little tougher.

The Russian manufacturer SS20 also offers a good option. Its shock absorbers, although less popular than Kayaba, are not inferior in quality. Typically, the Chevrolet Niva is equipped with SS20 shock absorbers of the comfort series (they are listed in the tables with analogues above). This series also combines relative rigidity and comfort. These shock absorbers are especially effective on rough roads at speeds above 40 km/h.

Shock absorbers on a Chevrolet Niva are replaced depending on their condition. As a rule, original racks can travel up to 80-90 thousand km on average. But there were often cases when SAAZ shock absorbers began to leak (and as a result lost their shock-absorbing characteristics) already at 30-40 thousand km.

How to change rear shock absorbers on a Chevrolet Niva with your own hands

Anyone can replace the rear shock absorber in Chevrolet Niva cars in 10 minutes. To do this, he will first need to do the preparatory work:

  • Use a metal brush to clean the threads of the fasteners;

Replacing the rear shock absorbers of a Chevy Niva occurs in the following order:

  1. Using a wrench, unscrew the bolt of the lower fastening of the device.
  2. Using two spanners, unscrew the nut from the bolt on the upper shock absorber mount, holding it with your hand.
  3. They take out the part.
  4. The new shock absorber is installed in the reverse order.

Replacing the front suspension springs on a Chevrolet Niva may be necessary if they are severely sagging or mechanically damaged. Signs of spring settlement include:

  1. Traces of collision of turns.
  2. The difference in height between the rear and front of the car.
  3. The front of the vehicle is skewed.
  4. Suspension breakdowns on uneven surfaces.
  5. Impaired smoothness.

To replace the front springs you will need two keys for “17”, two for “13” and one key for “24”, also a wrench for loosening the nuts on the car wheels and a jack. First, remove the wheel and loosen the lower arm axle nut using a wrench.

We unscrew the nut of the bolt that secures the shock absorber from below and pull out the bolt. Then unscrew two more bolts of the stabilizer pad bracket, and then remove the bracket. Raise the front suspension using a jack to release the compression stroke limiter. Next, unscrew the three ball joint mounting bolts and remove the bolts.

Then, slowly lowering the lever, you should release and remove the spring, after which we remove the upper and lower spring gaskets. If necessary, remove the compression stroke limiter. We install the springs in the reverse order.

Leveling up

There is no need to pump only gas monotube shock absorbers, in which the gas is reliably separated from the oil using a piston. Other types of parts need pumping. It's easy to do:

  1. Turn the shock absorber upside down and compress it smoothly.
  2. Wait 2-3 seconds.
  3. Turn the part upside down.
  4. Fix the part in this position for 4-6 seconds.
  5. Smoothly pull the rod out until it stops and rotate it 120 degrees.
  6. Repeat steps 1-5 at least 2 times.
  7. Check that the rod moves smoothly (without dips or jerks) in the chamber.

Do not turn the shock absorber over until it is installed on the vehicle. The rod must be at the top to prevent oil from flowing into the outer chamber.

Reviews

KAYABA. Gas-filled Japanese shock absorbers provide an excellent balance of comfort and handling. The best thing you can put on a Niva for fast driving on rough roads and dirt roads. However, after the “native” suspension from SAAZ, the car seems too stiff.

SAAZ. Soft, comfortable and inexpensive shock absorbers. Quite reliable - if you don’t drive over potholes and potholes, they don’t leak even after 80 thousand miles.

SS20. Driving characteristics of KAYABA at a price comparable to SAAZ. Over 30 thousand mileage no problems were noticed. I don’t think it makes sense to spend money on Japanese shock absorbers, which cost twice as much.

The need to replace shock absorbers and the reasons for their malfunctions

The device should be replaced when signs of failure appear, which include:

  • knocking sound when rocking;
  • rocking of the car when driving;
  • strong roll when turning;
  • uneven tire wear;
  • oil leaks on the shock absorber body.

This damping device operates in harsh conditions, exposed to aggressive environments: low temperatures, dirt, dust, rain and snow. All this affects the wear of the moving parts of the mechanism, oil seals, pistons and valves and is the main reason for their breakdown or failure. A faulty shock absorber is not only a source of discomfort when driving, body vibration, body swaying, and increased roll when turning.

Therefore, the damping device should be given special attention, technical inspection should be carried out in a timely manner, and if signs of malfunction occur, it should be replaced with a new one. Checking the condition of the shock absorber should begin with a visual inspection, making sure there are no scratches on the rod, the integrity of the oil seal and the absence of smudges on its body. The condition of the silent blocks, rubber bushings and cushions on the front suspension mounts should be assessed.

Possible reasons for replacing old shock absorbers on a Chevy Niva and signs of malfunctions

The cause of shock absorber malfunction can be various factors:

  • gas leak;
  • failure of silent blocks;
  • torn oil seal;
  • deformation of valve plates;
  • aging of fluid in the shock absorber.

Signs of a faulty car part on a Chevrolet Niva are easy to detect:

  • When accelerating and braking, the car “squats”.
  • when driving on an uneven surface, the suspension spring is compressed so that it reaches the limiter;
  • oil leaks on auto parts and the entire suspension;
  • drifts appear;
  • the quality of wheel adhesion to the road surface decreases;
  • The shaking inside the car increases.

Regardless of the quality of the shock absorber, as well as the operating conditions of the car, wear and tear on this part of the car occurs constantly. Therefore, regardless of the cause of the breakdown, it is recommended to immediately replace the failed device with a new one.

Instructions for replacing shock absorbers

Faulty devices should be replaced in pairs, and it is also advisable to install new rubber bands, bushings, rubber pads and silent blocks. Replacing the front shock absorbers of a Niva Chevrolet, just like the rear ones, is usually done on a lift, overpass or pit.

Removing the upper device:

  • Unscrew the top fastening of the rod, holding it with a wrench from turning it.
  • Remove the nut and washer that presses the rubber cushions to the body.
  • Unscrew the hinge nut, pull out the bolt and remove the shock absorber.

Shock absorbers are an important element of a vehicle’s suspension, determining not only a comfortable stay in the cabin, but also driving safety and the reliability of all components. Conscious selection of characteristics contributes to more efficient driving and the creation of a safe environment for all road users. One of the main prerequisites for the normal operation of the device is timely maintenance, identification of defects and their elimination.

Chevrolet Niva suspension diagnostics

To check the technical condition of the car suspension components, you should place the vehicle over the inspection hole and go down into it, or raise it (the car) on a special lift. It is very important, in this case, to suspend the front wheels.

  1. Make sure that there are no signs of mechanical damage or aging on the rubber parts.
  2. There should also be no signs of aging, cracks, separation of rubber from the reinforcement or its one-sided bulging on rubber-metal hinges. All damaged elements must be replaced.
