Signs of the replacement of the silent blocks of the front levers. How important are the silent blocks of the front levers? The device is from what the silent block consists of

Having arrived at the diagnosis in the car service, you can hear that silent blocks were worn in the car. For beginners who are just beginning to learn to serve their car on their own, this word will be incomprehensible. Having studied this material, novice motorists will recognize that they are hinges where they are located, how to determine the malfunction in this node and, most importantly, how to replace silent blocks of VAZ 2110 levers

Purpose and location of silent blocks

The word "silent blocks" came from foreign cars, before these elements were called rubberometallic hinges. The part is the connection of two metal tubes, between which there is an insert from rubber. Silent blocks are installed in the rear and front suspension. The task of these elements is to change the angles of the arrangement of Wheel VAZ 2110. Also they are combining parts of the suspension and quench the oscillations that appear during the ride.

Important! The approximate resource of silent blocks is 100 thousand kilometers, but sometimes these details are wearing ahead of time. Service time depends on many factors: driving style, garage, regularity Diagnostics VAZ 2110.

In this material, the replacement of silent blocks will be disassembled in the front suspension, since here they have large loads, as a result, rubber shares, and tubes wear out. These details of the VAZ 2110 are installed on the rear and front levers. Hinges are also used as motor mounts, gearbox and shock absorbers. Replacement can be performed independently in the presence of observation pit and jack.

Signs of faults

It is quite simple to determine that the reason for the faulty work of the front suspension is silent blocks are quite simple. Signs of malfunctions of these parts are as follows:

• From under the front wheels of VAZ 2110, a unnatural scrolling of rubber comes from the noise published by the wheels.
• The appearance of the knock in the front of the car. This is due to the wear of rubberometallic hinges, which cease to slide, as a result, noise appearance.
• Also, a malfunction can be determined with visual inspection - cracks, breaks and other defects appear on the rubber.
• When these signs appear, you need to get hinges from the rear and front levers and inspect them for damage. Repair Metal Rubberometallic Hinges are not amenable, so replacement of new details is required.

Replacing Silent Blocks VAZ 2110: Required Tools

The following tools and equipment will be required for work:

• Puller.
• A set of keys.
• Screwdriver Set.
• A hammer.
• Vice.
• Chisel.
• WD-40.
• Looking pit and jack.

The puller is the most important tool, since the dismantling of silent blocks and the replacement cannot be performed without a puller. The device can be bought or make it yourself. The puller consists of a wide and thick washer, high nut, M12 bolt and sleeve, the length of which is 60 mm, and the inner diameter is 38 mm.

Instructions for replacing the silent blocks of lower and swivel levers

There is a replacement of the silent blocks of the front levers as follows:

1. Machine must be put on the pit. If the VAZ 2110 presents the protection of the engine compartment, then it must be dismantled. Next, you should remove the bolts nuts that keep the front levers. You can then unscrew the nuts of the bolts connecting the lever and the stabilizer. After removing the wheel bolts, the car needs to raise the jack and dismantle the wheel;
2. Armed with the "24" key, you must unscrew the nuts of stretch marks. If the attachments are not amenable, they need to be treated with WD-40. After removing the naika rounded fist And the ball support can be divided. Now the front lever can be completely removed;
3. Ready, now faulty silent blocks can be reached. Next, you should take new details and presses them into the lever with the help of vice. First you need to put the solent blocks of stretching. It rarely happens that the block is completely sat down in the lever, it can be fixed by several hammer blows;
4. The next step will be subject to the silent blocks of levers. If the item is completely worn, it will fall out after the hammer strikes. New detail Before installing in the lever you need to lubricate. As the experience of VAZ 2110 owners shows, it is best to lubricate with soap water or liquid soap. Ready, replacement completed, the assembly is performed in the reverse order.

Tip! Stretched nuts are very difficult to unscrew, so it's better not to spend 10 minutes on every round of thread, and dismantle the lever with a stretch.

Check Saylentblok

Sometimes it is impossible to immediately determine the detail of the VAZ 2110 or not. Check silent blocks can be without dismantling. To do this, you need to call on watching pit And to inspect the hinge - it should be clean, otherwise damage can not be noticed. The rubber part of the hinge should not have breaks or cracks. Another sign damaged details - It is an incorrect collapse / convergence. When the hinges are torn, the lower and swivel levers lose stability and become crooked.

It is also necessary to check the backlash if it is too big, it will be necessary to replace. It is not recommended to postpone the repair, since faulty rubberometallic hinges negatively affect the handling of the VAZ 2110: the car takes and throws.

Imagine the situation, you come to the diagnosis and the master says it is time to change silent blocks. But you do not know what it is. In this article, we will tell: what is the silent block in the car, for what is needed and why change.

What it is

Silentblock (correctly so to speak and write, not "Salenblock" or "Saynblock"), or a different rubber-metal hinge, represents two metal sleeves, between which there is a rubber insert. They serve to connect the parts of the suspension and due to the elastic insert between the sleeves (rubber or polyurethane) extinguishes the oscillations transmitted from one node to another.

Where is the silent block installed? They meet both in the front suspension of the car, for fastening the levers, stabilizer transverse stabilityand for connections in the rear suspension. They are also used to fasten the gearbox and engine.

How to check and what resource

How to understand when it time to change silent blocks? Usually, they serve to 100,000 km run, but in russian conditionsIt should be examined every 60,000 km of run. You can understand the suspension silent block in your feelings. If the car has become worse than driving or reaction to the steering wheel turn with a big delay - this is a faithful sign of a worn hinge. For greater confidence, you need to contact the service or make control of rubberometallic hinges yourself.

Visual inspection occurs as follows: You need to go to the pit and look at the pure dirt of the silent block. In the rubber part there should be no cracks and breaks. It is desirable to represent what a new one looks like. An indirect feature is considered a column / convergence curve if it used to be correct. When silent blocks are rushing, the levers become a little crooked.

Slave to check the backlash in silent blocks and at an excessive size - to replace urgently.

What leads to unreasonable replacement? With their strong wear, car can appear at speed. Those. The car will flush from side to side. Another sign of wear is uneven wear of the tires. Do not slow with replacement, because They can destroy the landing places of attachment of hinges, and then, for example, you will have to change the front pendant lever assembly.

Conventional sailing of rubber serve to 100 thousand km, and may be 40 and 60 thousand. For example, in the back of the beam, more than 150,000 km go, in the front suspension of 60-80 thousand. It all depends on the operating conditions. As for polyurethane, according to the idea, the fact that they serve as 5 times longer - this is a marketing move, no one really checked. But 2-3 times longer than rubber they will serve. Plus, they are resistant to a strong frost, when rubber salted blocks can crack, and mean last longer. Also, polyurethane is not afraid of oil, it is also plus to their fun.

Polyurethane or rubber silent blocks

If the car has in the suspension rubber sleeves And silent blocks that can be replaced by polyurethane details, then only improve the characteristics of the suspension and its operation. Polyurethane silent blocks serve at least 5 times longerthan rubber parts. The only drawback of polyurethane is more high price Compared to rubber products (more than 5 times), but you can save on replacement.

Polyurethane silent blocks improve the behavior of the car on the road, reducing unwanted deformations in the suspension and eliminate the "squeezing" effect, characteristic of rubber parts. This means that the suspension always works in the mode provided by designers. Properly installed and selected polyurethane parts work better, absorbing blows, vibration and reducing noise compared to rubber.

If you want to improve controllability - polyurethane silent blocks are what you need. If you calmly move from one point to another, then choose in favor of conventional rubber-metal sleeves.

The replacement and diagnosis of silent blocks on the car includes a list of service services provided by a hundred carfraud. When the moment comes to replace silent blocks, and how to do it yourself?

How to check silent blocks for wear and defects - diagnostics

Regular maintenance of yours vehicle — prerequisite (As you know all drivers) for safety on the road.

To a large extent, this applies to the chassis and suspension of the car, its nodes and separate items.

One of the elements (seemingly insignificant, but extremely important) is silentblok., which is 2 metal sleeves with a rubber insert in the center.

This element connects the pendant parts - and, due to the elastic (polyurethane or rubber) insert, it extends transmitted from the 1st node to another oscillation. It is on it that the most powerful loads: the silent block is called upon to "hold a blow" obtained by suspension vehicle.

Where is the silent block?

Preferably, this item is installed in front I. rear suspension TC.

In addition, the item uses as a fixing element For gearbox, for shock absorbers and engine.

Naturally, regular control is needed over each such shock absorber.

Substitution of silent blocks: How to determine what time has come?

As a rule, the service life of silent block is about 100,000 km of run. But given the state of the Russian "off-road", the inspection of the elements is recommended every 50,000 km.

The following "Symptoms" is becoming a reason for appealing to a service station in this case ...

• Bad controllability of the vehicle.
• "Inhibited" steering reaction to turn.
• Cracks and ruptures on the rubber part of the element with visual inspection on the "pit."
• The collapse of the collapse / convergence (suddenly discovered).
• Excessive backlash in the element.
• Non-equal wear of tires (which eloquently speaks about the problems of the gathering-collapse and, accordingly, suspension).

Repair or wait?

Strong wear of silent blocks threatens the fact that the car at speed suddenly "behaves." Even in the summer, this can cause an accident, what to say about the winter. Therefore, the replacement of the elements is obligatory.

It is also worth noting that in case of destruction seating Fastening the joints themselves will need replacement front / lever suspension assembly. That is why timely diagnosis is so important.

Diagnostics - how to identify the problem or make it in absence?

1. We visit the "pit" or raise the vehicle with the help of a jack.
2. Remove ball supports.
3. Check the parts whose work is associated with silent block. Sold down the suspension lever on the sides: you need to make sure that it does not "fall." The lever must, sip, return to its natural position (if it is working).
4. Check the sleeve. It should not be observed to turn on the faces.
5. We check directly silent block: on the knock inside the element, as well as the presence of visible mechanical damage and cracks (approx. - on rubber and metal).
6. We check - there is no backlash. Its presence is a signal to the urgent replacement of the element.

Substitution of silent blocks by car - phased instruction

To replace silent blocks should be prepared.

Do not do BUD without a jack or pit, set to replace parts and tools needed to exercise silent block.

1. The vehicle is installed on the "pit" (viewing) and dismantle the protection of the crankcase when it is presented.
2. Unscrew the nuts that serve to fix the front levers. We unscrew the key number 17, with the help of which the stabilizer is attached to the lever, and get the bolt with a hammer (manually removed is very difficult).
3. We tear the bolts for fastening the front / wheels and lift the way to us the TC by the jack, after which the wheel is removed.
4. Next comes the twisting the following nuts - on stretching. It will not work out without a key with the shoulder. Note: Before unscrewing, the VD-40 nuts should be treated (a well-known substance).
5. After - a ball support, which is moved from a swivel / cam, and a couple of bolts, after the twisting of which the lever disasses occurs.
6. Now the silent blocks are dismantled with a special device, and is cleaned from the dirt of the eye.
7. Next - the clue of new elements. In the absence of a special / set for their replacement, a hammer, chisel and Russian cutter are used. But there is a risk of damage to the element or its part.
8. Then the pressed silent block is lubricated with soapy and is installed on its rightful place. We return everything to the place, but already in the reverse order (except the old silent blocks, of course).

Important!

After replacing silent blocks, the collapse / convergence procedure is carried out in a mandatory procedure if something during dismantling was broken.

Of course, in the presence of talents and minimal knowledge of the device, independently replace the elements described above.

But with the slightest doubt, entrust this time-consuming procedure to specialists ( independent replacement Silent blocks flew more than once folk craftsmen in a penny). AND do not pull a visit to one hundred - Safety is more expensive!

With the replacement of silent blocks you will be helped by where you are waiting for professionals with perennial experience, high quality modern equipment and democratic prices.

Video instructions for replacing silent blocks by car

Silentblock is a detail of the car whose task is to reduce the noise of the suspension. Silentblok is an intermediary between the suspension element (subframe, spring, shock absorber, lever, etc. and a rigid body structure. If you screw the metal part of the suspension to the metal part of the body, you will perfectly hear every hesitation of the suspension, the connection will be too tough, which will reduce the level of the car's comfort.

How Saylentblock is arranged

In essence, the silent block, it is a cylinder, inside which rubber is inserted, and that the rubber is not extended about the fastening bolt, the mettaric sleeve is inserted into the rubber. See the picture, as it looks live.

As a result, all blows on the suspension swallow the rubber part, and almost nothing comes on the body.

How to understand that the silent block has failed

Everything is simple: it ceases to perform its functions, and you start to hear blows when driving irregularities with a large amplitude of the wheel stroke (rails, deep bumps). If the suspension starts knocking, inspect it from the pit. With the outstanding silent block, the rubber part of the breakdown, and during the movement of the lever you can see that the silent block allows you to move too much to your inner sleeve.

Since the silent block is not able to more hold the suspension assembly, the clarity of the suspension is disturbed, the machine can begin to vive, requiring a friend. Of course, it will be impossible to speak about normal collapse, but the suspension will not be able to configure the suspension, since when the car is displaced, the collapse will constantly change. Good way Diagnostics: Pneumonide, which creates a sufficiently large load on the wheel, as a result of which all sore places will get outward.

What silent blocks are

They are arranged all the same, however, to prevent the transfer of a large number of noise, or to increase mobility, the rubber part is often not solid, but as part of two parts connected by partitions. Sometimes, in order to reduce wear resistance, the rubber part is replaced with a polyurethane analogue. Polectopian silent blocks are somewhat gesticily and noiser, but in general their behavior is more.

Causes of failure and what breaks in the silent block

Present to break the metal parts of the silent block is quite difficult. If they say that sayylent block broke, it means that the rubber component of the part began to rush or have already broken. Causes of silent block failures Three:

• Long service life, resulting in a rumper dried, lost elasticity and began to crack and break
• Chemical impact on the rubber part. For example, there is too much oil on the silent block, which runs it.
• Incorrect installation. Saylent block bolts must be pulled only when the car stands on wheels, and not on weight. But alas, many car services do not comply with this rule, as a result, the wheel-tightened wheel is at the extreme point, and when it stands on the wheels, the silent block is very twisted and the rubber will be bored with time, without recovering and a third of its term. Another subtle moment is the installation of silent block with partitions. Such silent blocks can be installed in a strictly defined position, and if it is wrong, the silent block will fail very quickly.

How to replace silent block

As a rule, Silent block first is screwed to one part or is closed into it, which matches it with its outer shell, after which the item is put in its place and is screwed by a bolt, which has been shifted through the inner sleeve of silent block.

Knowing how the silent block is installed, it is not difficult to guess, which is extracted or knocking, or by unscrewing. When knocking out, or recounting is very important not to damage the plane, pairing the silent block and the suspension element, since the silent block may then enter it loose or not to be pressed.

When installing, pay attention to how the silent block should stand, since not all silent blocks can be delivered arbitrarily. If the silent block has a design with partitions, it must have a strict working position. If you ignore the strict installation position, the load on the partition will be too big and silent block will fail.

Hanging suspension with connections through a silent block is performed exclusively in the "Machine standing position on the ground", since the suspension must take the working position before dragging. If you ignore this rule, silent block twists and its resource will significantly decrease.

Silent blocks of Lada (VAZ) are able to withstand from 50 to 200 thousand kilometers of the car. It all depends on the operating conditions and proper diagnostics. Our article is about how the role is playing silent blocks, how to check the silent blocks of the front levers and how to save them, so as not to spend money in the car service every 30 thousand runs.

Silent blocks call rubberometallic hinges, which are two metal sleeves, having a rubber insert with each other. These parts provide a connection of various suspension elements. Thanks to the elastic insertion (rubber or polyurethane), vibration is quenched, which occurs during the movement of the car.

Silent block diagnostics

Requirements for easy diagnostics of silent blocks do it yourself:

• Raise the car (jack or lift)
• Visually examine defects of rubber inserts
• Check the lever behavior when swinging
• Listen to the subject of knocks and backlash.

The main signs of the malfunction of the silent blocks of the front levers are permanent liabilities of the machine from the course and the uneven wear of the tires. Noticing these features, do not rush to grab the head and wallet. Try first to deal with the problem yourself. The diagnosis of silent blocks is pretty simple.

To do this, it is enough to use a lift or jack. On a suspended car, ball supports are disconnected and here you, the state of silent blocks - as on the palm. The suspension lever should not fall. With vertical swing, he must sink and return to the original position. Actually, this is his work. Silent block sleeve relative to the faces should not be turned. If any of this does not correspond to the real state - signs of wear of the silent blocks of the front levers on the face.

Thanks for the subscription!

At the same time, visually examine the suspension hinge for the absence of possible rubber thorns. In places of hinged connections, rubber can also crack or scatter. The diagnosis of silent blocks requires paying attention to both the presence of a backlash. As a result, the car may be required urgent replacement of silent blocks. Remember! Belated destroys the locations of the hinges contacts, and this is fraught with a complete replacement of the front lever of the suspension.
