Smooth roads: how and why change the bushings of the stabilizer. Replacing the stabilizer bushings - when you need to change the bushings? How to replace the front stabilizer bushings

The main task of the suspension is to ensure an elastic connection between the body and wheels. Thus, the suspension softens the shocks and jumps that occur when the car is moving along an uneven road or its absence. The smoothness of the car's stroke directly depends on the suspension.

The suspension serves as a peculiar shock absorber, absorbing energy that occurs when driving on unevenness, or ingressing in pits and pivots. However, it does not guarantee the complete softness of the movement and is strongly wearing at a frequent movement by irregularities.

Pendants are divided into the following types:

• McPherson;
• duplex;
• multi-type;
• adaptive;
• "De Dion";
• rear dependent;
• rear semi-dependent;
• pickups and SUVs;
• trucks.

McPherson type suspension

McPherson type suspension is one of the oldest. Was developed by a talented engineer Erl MacPherson in 1960. It consists of a transverse stability stabilizer, lever and block. A serious disadvantage of the suspension is the change in the corner of the wheels, but it is very popular due to availability and reliability.

Double suspension

A two-way suspension is one of the most advanced designs. This is a suspension with two levers of different lengths (top short and lower long). This design allows the car to keep stability on the road and ensures the durability of the tires. Each wheel takes its obstacle independently and does not reck out the load on other wheels.

The multi-dimensional suspension was developed not so long ago and is an even more advanced design. It is a set of multiple levers, silent blocks and hinges. All of these components are designed to guess blows and strong shocks while driving. The noise level from the wheel in the cabin also decreases. The suspension has separate transverse and longitudinal adjustments. Wheels are independent of each other. The design is ideal for all-wheel drive cars.

Cost multi-dimensional suspension Some time remained rather high, but now even golf class cars can afford it.

Adaptive suspension

Adaptive suspension is very curious in terms of design. For a long time, I was primitive and weighed a lot, but now it was very modernized. Due to this, it allows the maximum body roll and wave rack at high speed and allows you to automatically adapt to any type of road coating. Part adaptive suspension Input: Adjustable transverse stability stabilizers, active shock absorbers racks, control unit chassis and electronic sensors fixing road irregularities and other parameters.

"De Dion"

"De Dion" is named so in honor of its Creator-Frenchman. The main function of such suspension is to reduce the load on rear axle Car by separating the crankcase of the main transfer. Carter in this case holds on the body. This design allows you to make a suspension dependent or independent. But there are disadvantages. With a sharp start, the car body can be very pressing on the rear axle.

Rear dependent suspension

The rear dependent suspension is a real classic option, as it was used on many old VAZ cars. The suspension is based on cylindrical screw springs, which are elastic elements. The beam of the rear axle "hangs" on the springs and is fixed to the body by four longitudinal levers. The reactive transverse rod performs the role of the rolls of rolls and has a positive effect on handling. But the comfort and smoothness of the move from this suspension do not wait, as the rear axle weighs a lot.

Half-dependent rear suspension most often used in cars with fully drive. Its basic elements are two longitudinal leverage, fitting in the center of the cross. Such suspension weighs a bit and does not require any special maintenance and serious repair. But on the rear-wheel drive cars such a suspension cannot be installed.

Other types of suspension

The suspension of trucks is most often dependent with transverse or longitudinal springs and hydraulic shock absorbers. This design allows you to simplify the process of production and repair of trucks.

Transverse Stability Stabilizer: Design and Purpose

Stabilizer of transverse stability - an indispensable part of the suspension. It provides a reduction in the rhombus of the body when turning, an increase in the clutch of the wheels with the road surface and the uniform distribution of the load on the frame. The form resembles a metal beam with curved tips. Each side is attached to the wheels of one of the axes, most often in the front (front stabilizer). Also, this design element is attached to the car body.

Suspension diagnostics in the service center

The cost of such a diagnosis varies from five hundred and thousand rubles. Diagnostics allows you to identify the suspension defects. Since this part of the car is most susceptible to wear, then the diagnostics should be carried out quickly and timely.

Determine that the time has come to check the suspension for goodness, you can on an uncharacteristic knock and an increase in the braking car. The stability of the car on the road over time also weakens. Diagnostics in service centers are performed using high-precision equipment (a luftomer, lateral care tester) and provides maximum informativeness. After the diagnosis, you will receive a special diagnostic card with the results of work.

Special sleeves are used to set the stabilizer. What is the sleeve? These are elastic elements providing a car smoothness. These bushings also provide noise and vibration from the stabilizer.

The bushing is created by casting from rubber or polyurethane. The form for most models is identical. Additionally, equipped with grooves protecting from mechanical exposure.

Signs of wear of the stabilizer bushings

There are several signs:

• education of the steering wheel of the steering wheel during the execution of turns;
• steering steering;
• body roll with different knocks and clicks;
• vibration and extraneous noise;
• "WORK" of the car aside when moving straight;
• unstability on the road.

Causes of fault of the sleeve

The bushings most often fail due to bad road coat, Applications of various reagents. Reagents that are used during the ice are no exception. Aggressive driving style with sharp braking and start quickly leads to the wear of most of the designs of the car, including the stabilizer bushings.

Serious cause of wear can be low temperatures. Rubber of poor-quality sleeves will hard and lose the necessary elasticity.

And finally, the most serious factor of wear is the time. Stabilizer bushing, like most elements of the car design, is a spare part of shelf life. Any sleeve is sooner or late to wear and requires replacement.

Before replacing the stabilizer bushings, it is necessary to thoroughly inspect the suspension. The suspension must be cleaned of dirt. You can determine the wear of the sleeve visually: it will be patterned cracks and various sweetes. Rubber of wear sleeves loses elasticity. For inspection of the sleeves, a special observation pit or an elevator will help you. If there are no such amenities - take advantage of the "folk" way. Hands up in the top of the roof of the car and shake it. The knocks and creak at the bottom of the case will be a signal to replace the sleeves.

Some car owners are trying to extend the durability of the sleeves using special lubricants. This method is not recommended because the lubricant in the process of motion "collects" various road trash and dust. But if you still decided to take advantage of the lubricant, then buy a quality product that does not destroy the rubber. You are suitable "Litol-24" and "Molykote Cu-7439". These are universal products. They can be used even for lubrication brake calipers. Lubricant sleeves are often available in the repair kit. In some cases, you may need a scrap.

To replace the sleeves you will need one or more jacks. It is advisable to replace the observation pit, where special supports may also be needed. From the tools will need wrench, screwdriver and repair kit.

Step-by-step instructions for self-replacement

The process of replacing the front and transverse stabilizer Some are different.

To replace bushings front stabilizer You need to make a number of actions described below:

1. Install the car still above the observation pit or on the lifting.
2. Using tools Loosen the wheel bolts that are in front.
3. Remove the wheels.
4. Unscrew the mounting nuts to the stabilizer.
5. Disconnect the rack and stabilizer.
6. Loosen the rear brackets fastening bolts that frames the sleeve, and then unscrew the front bolts.
7. Clean the place to install new sleeves from the mud.
8. Lubricate the inner side of the bushes with a silicone spray or soap solution. To do this, it may also be suitable for a special lubricant available in the remnabilities.
9. Set the stabilizer bushings and reverse the installation of all parts.

To replace the cross stabilizer bushings, you also need to install the car stationary over the pit or on the lift. After that, make a number of actions described below:

1. Place the anti-digit shoes under rear wheels Car and slightly raise the front.
2. Special horny key, unscrew the nuts on the brackets in places where they are attached to the bottom lever of the car suspension. Spend this operation on both sides of the stabilizer bar. Hoters-grovers under nuts are removed manually.
3. Remove the brackets and remove worn sleeves. To do this, beat the stabilizer bar scrap and hold it with the same scrap when removing the sleeve.
4. If there are central sleeves, you will have to remove the stabilizer bar, which is fixed on two brackets. Nuts on them can be unscrewed by a wheelchair key.
5. After removing the bar, clamp the bracket in vice. Then you can remove the bar, and then the sleeve.
6. Replace the bushings, clearing the place of installation from dirt and having lubricated.
7. Further, as usual, reverse installation is carried out.

As is known, the transverse stability stabilizer avoids the limit loads on separate parts of the chassis. If simply, the stability of the car on the road directly depends on his work, also the stabilizer does not allow the body strongly roll into turns. This combines the stabilizer with other details through.

Also, to reduce the noise and absorption of vibrations, which occur during the work of the stabilizer, the design of the stabilizer is used in the design (made of rubber and in everyday life are called stabilizer gum). Next, we will look at what the stabilizer bushing is, as it works and works, as well as to check the stabilizer bushings and how the sleeve is replaced.

First of all, the stabilizer bushing is a detail cast from rubber or polyurethane. As a rule, for different cars, the form is often very similar. It should also be noted that to improve the resource and reliability of the stub bushings have grooves and tides. These refinement allowed to protect the bushings from mechanical damage.

The product is obtained simple, but its functions are sufficiently important. Not only comfort depends on the state of the sleeves, but also the quality of the stabilizer itself. For this reason, it should be borne in mind that any defects of the bushings are grounds for their replacement.

In other words, if during the verification process it was revealed that the rear stabilizer sleeve or front stabilizer sleeve was damaged, deformed or destroyed, it is necessary to change them. Replacing the transverse stabilizer bushings is shown in the case when even small cracks are visible or an explicit change in rubber properties is noted.

As a rule, the replacement is required every 30-40 thousand km. Run or 5-6 years. At the same time, experts recommend changing all the sleeves for one approach, that is, even if only one element has failed. When inspected, it is important to clean the sleeves from the dirt so as not to miss defects and increase the service life of the part if the replacement is currently not required.

Also, the replacement is needed when such signs are manifested:

• the steering wheel of the bearer with the passage of turns, a beating appeared on the steering wheel;
• the body is strongly cubed, clips, tapping, violets are heard during inclons;
• suspension vibrates, surveillance noises
• there was an exploration of a car when driving in a straight line;
• a noticeable loss of stability, the car does not hold the road;

Of course, these signs are only indirect, as you can pass the car or beat in the steering wheel, for other reasons (for example, a banal situation, when there is a place), however, the stabilizer bushings should be checked in the diagnostics. If after their replacement, the signs of faults did not disappear, then there is an in-depth diagnostics of the chassis.

Also note that the creak of the stabilizer bushings is although it is not an acute and dangerous problem, but strongly worsens the complex of operation of the vehicle. For this reason, the replacement of the sleeves is also practiced if the stabilizer bushings fasten.

How to replace stabilizer bushings

So, at the initial stage it is important to understand, on which axis it is necessary to replace (rear stabilizer sleeves or front stabilizer bushings). At the same time, in practice, more often need to replace the front stub bushing, so we will stop in more detail.

First of all, replacing the front stabilizer bushings on different models May differ somewhat, but the overall replacement procedure is often similar and is not difficult. The main thing is to prepare the necessary tools.

The general procedure of action, within which the front stabilizer bushings are replaced:

• drive the car to the pit or on the lift;
• remove the wheels from the car;
• unscrew the attachments of the racks to the stabilizer;
• disconnect the racks and stabilizer;
• check the stabilizer rack bushings and the Stub Rack itself (replace if necessary);
• weaken the rear bracket bolts holding the sleeve, then unscrew the front;
• after removing the old sleeves, it is necessary to remove the dirt in the installation places of new sleeves;
• apply a soap solution or silicone spray, you need to smear the bushings with inner;
• put new bushings and harvest in reverse order;

We add that the replacement of the rear stabilizer bushings is not particularly different from the replacement of the front, but the front stabilizer sleeve changes somewhat more complicated, as it is more complicated by design. In fact, if you managed to change the front sleeves, there will be no problems with the rear sleeves.

By the way, as for the squeaks of the sleeves, mentioned above, usually the sleeves will creak in winter in the cold or in hot dry weather. The reason is the low cost of the material from which the bushings or features of the car design are made. Also tires can harden in the cold, loses elasticity and creak. Another creak points to the critical wear of the bush.

Please note, in some cases, the owners are trying to get rid of creaks by lubricating the stabilizer bushings. So, if you need replacing the stabilizer bush due to wear of rubber, then no lubricants will help, as the item is deformed.

If the replacement of the stabilizer gum was recently produced and they good condition, then you can count on the temporary effect after lubrication. It is important to understand that the lubricant contributes to the sticking of dirt and sand on the sleeve. Of course, the abrasive particles reduce the bushow resource.

It should also be noted that the bushings should firmly crimizer. If the connection is not so reliable, the stabilizer may begin to scroll, the creak in this case is only enhanced.

The main thing is not to use aggressive lubricant to rubber, as they destroy the bushings. We also note that some more major automakers produce stabilizer bushings with anthers who protect the inner surface of the sleeves from dirt, dust, water, etc. If you can buy something similar to your car, it is strongly recommended to stop at such versions, even if they are more expensive.

Let's summarize

As you can see, the bushing of the rear stabilizer or the front stabilizer bushing is simple element both in terms of design and in terms of replacement. At the same time, the stabilizer rack bushing and the stabilizer bushing are different, so it is important not to confuse these items when selecting the necessary spare parts.

Finally, we note that the front or rear bushings of the stabilizer with all its simplicity perform important functions, allowing the stabilizer normally and quickly work, effectively extinguish rolls and oscillations. In turn, it allows you to improve comfort, as well as improve the stability and control of the car, thereby increasing safety during the operation of the vehicle.

What is a silent block in a car device: device, basic functions. Signs of silent block faults, why and when silent blocks need to be changed.

Elements in the design of the car, which perform the function of providing stability while driving on the road, are called stabilizers. In order for the work to be silent, soft and smooth stabilizers are installed on the sleeve. Stabilizer bushings are relatively soft and elastic rubber parts.

What is the stabilizer bushing?

The sleeve is made by casting. Material used for manufacture: Rubber or polyurethane. The form of this part is almost the same for all models of cars. To harden the design of the sleeves, they make grooves and tides.

When to change the front transverse stabilizer bushings?

Conducting from time to time a visual examination of the stabilizer bushings, you can reveal their wear. If there are cracks on the sleeve, the form has changed (there is a large scope), then it is necessary to replace the stabilizative sleeves.

The resource of the bushings by the stabilizer for most brands and models of cars is 30 thousand km of mileage. If only one sleeve was worn out, it is recommended to change the full set to increase the interremmer period to replace the sleeves.

If the visual inspection is visible dirt, it is better to clean them, thereby protect against accelerated wear.

Signs When you need to change the stabilizer bushings in the car:

• if the play of the wheels appeared when turning;
• if the steering wheel beats;
• if there are screenshots during inclons (roll) of the car;
• if the suspension vibrates (there is extraneous noises);
• if when moving straight the car pulls to the left or right;
• and, if at all there is instability during the ride.

These signs, first of all, signal the wear of the stabilizer bushings. The same features may also accompany the wear of silent blocks. Such problems and subsequent passage of work on the collapse are eliminated. Therefore, you should check and hold them repair work With its own or other people's hands stabilizative sleeves. The backlash may appear with a strong disruption of wheel balancing. Violates balancing when you hit the pit, or, for example, when downloading to close the puncture.

How to change the front car stabilizer bushings

Although the brands and models of cars are a huge amount, but the principle and order of work on the replacement of the front sleeves, almost the same. Mainly different tools are distinguished.

The right order of work on the replacement of the front sleeves:

1. Install auto on the lift (if available) or set over the observation pit.
2. Loosen the fastening bolts of the front wheels.
3. Remove the wheels.
4. Then the nuts attaching the racks to the stabilizer should be unscrewed.
5. Disconnect.
6. Then the rear bracket bolts should be loosen and unscrew the front bolts.
7. Clear places for sets of bushings from dirt.
8. New sleeves from the inside should be lubricated with soap solution or silicone lubrication.
9. Install bushings and make actions, reverse disassembly.

In some designs, cars will be more convenient to replace the front sleeves, if you first remove the protection of the engine crankcase.

The rear bushings of the stabilizer are changed by analogy with the front. Usually, the front is harder than the rear. When wearing the rear sleeves, creak appears.

Skin stabilizer sleeves

The appearance of a violep when moving the car, the driver and passengers are felt often. Especially begin to creak with severe frosts.

Consider the reasons for the appearance of the squeak of sleeves:

1. The bushings were made of low grade material.
2. In the cold, the tires is oak and loses elasticity because of what screensions appear.
3. The sleeve is very worn.

Methods for eliminating the violep of automotive bushow stabilizers:

By logic, in order to eliminate the creaking, you need to smear the bushings, which make some drivers. But, lubrication, be it lithol 24, various oils- All this attracts dust, sand. The adhesive abrasive substances will only lead to the rapid wear of the bushings.

Also, the lubricant will lead to a partial loss of the function of the bushings themselves, as they should hold the stabilizers tightly. The bushings are triggered to twist and, so they protect from the roll roll. For proper operation of the sleeve, you need them tightly. And if they are lubricated, they will already slide and can rotate.

There are ways of folk craftsmen to improve the efficiency of the stabilizer bushings. They wrap part of the bushings with a tape so that they sat tightly.

The video shows the process of replacing ordinary sleeves to polyurethane.

Before dealing with the theme that such a stabilizer bushing, would not bother to refresh the knowledge about the stabilizers themselves, what are they needed for? The main task of this detail is to hold the car to the maximum parallel road. Despite the various risks, for example, turns, braking, which cause both transverse and longitudinal rolls. Change with them and must stabilizer.

Stabilizer Bushing - Yellow

With the slightest roll, the ends of the stabilizers begin to move, thereby reducing the roll. The movement occurs in the bushings, which will be discussed. The purpose of the latter is that the stabilizer can curl in multidirectional. That is why it is fixed with the help of sleeves. Over time, the bushings are erased, which arises backlash, which will serve to malfunction for the entire mechanism. The so-called "freedom of details" increases, then by and large the role in the presence of the stabilizer is not. Because it is absence of it, rolls increase due to large moves and rotation, manageability is lost and it is felt for the most part in the turns.

Views

There are several varieties of bushings:

Rubber bushings.

Polyurethane. Similar to the previous one, with the exception of production material.

Recently, motorists prefer polyurethane bushing, due to their high performance characteristics. As a rule, "go" longer. But, it is also individually, depending on how to ride.

It is also not necessary to release such a nuance from the type that for almost every model its sizes and configuration of the sleeves, which special attention need to be given the choice and the selection under specific model. The most acute this question is worth foreign cars.

What is the resource?

This question is quite individual, as such as accurate "runs", no manufacturer can give. It all depends on the specific operating conditions, having the mind that bad roads, driving style, all this affects the "life" of the sleeve, and in general the mechanism of the stabilizer.

By the way, the bushings are considered the most problem Most In the suspension on Lada Vesta. Almost immediately from the plant begins the creaking, it is not rarely added to it during the movement on the bodies. The problem is that it is used not high-quality material for the manufacture, which is why the resource of the native sleeves on Vesta is quite small. It's necessary to be treated all trite simply, it is necessary to choose analogs from other models. For example, it is known that the sleeves from Toyota kings, Avensis and Kia Rio are great and do not deliver owners of West, problems.

If you judge, according to the reviews of drivers, the bushings of German brands have shown well, which are often installed on the "Germans" from the plant. For example, native details can often serve more than 150,000 km. At the same time, when it comes to analogs from China, the resource is reduced several times.

In general, among motorists it is believed that the average "mileage" for rubber sleeve 70,000 km, more improved polyurethane 100,000 km "run." Some manufacturers are at all recommend to conduct a planned replacement after 30,000 km to avoid the appearance of "surprises". But, as already mentioned, everything is individually, you need to take into account all the features of operation.

It is also worth clarifying such a nuance, the state of the traction itself (Stub) has a huge impact on the resource of the bushille. For example, if there is a development of the sleeve at the fastening site, then the detail will not lastly serve and fully cope with the task will not be fully. As a rule, after replacing the native sleeves, the owners observe a small metal generation, somewhere about 1.5 mm. With each replacement of the sleeves, the development will only increase, so it is more intelligent to replace the part entirely so that it is a sense, in general, from the operation of this mechanism.

Signs of faults

The features below may indicate that something is not fine in the suspension. And one of the places worth checking is a stabilizer. So:

A small backlash is formed when the steering wheel is rotated.

The car began to "scour" when driving.

In turns from the wheel, distinct clicks are heard.

The car leads one way.

Welcome vibration.

How to replace?

The issue of replacement for some cars is purely individual, because depending on the model, the attachments may differ. For example, to replace the sleeves on the Mazda 6 and 5 in front, you will have to remove and steering traction to get to the brackets of the string itself. But, in general, you can make a small work plan. So:

Raise the car on the lift or beat on the pit, for convenience.

Keide the mind that bolts and then may not succumb. Then the "Bulgarian" takes into business. But the fuel hoses from the "dangerous" zone are preliminary. Cut the "ears" of the bracket to "free" the bar.

After unscrewed the brackets (clamps), as if we assign the stabilizer itself from the subframe to make it easier to remove the sleeve. Use the Lomik.

We are tightened by the old sleeve.

Wear a new detail.

Replaced the sleeve

Please note, in most cases, the claw on the new sleeve "sits" is extremely bad, so try to arrange it as soon as possible, minimize friction (use lubrication).

Attract the claw claw. By the way, we pre-recommend to treat lubricant and bolt with a nut so that there are no problems with unscrewing in the future.

By the way, such an important nuance during the replacement. You need to change both bushings immediately, that is, not to leave on the right side old detail, and left, for example, install a new one. On both sides there must be new sleeves.
