Today, the technological structure of a car is a whole complex of highly complex mechanisms, assemblies and parts. If you are not an advanced car enthusiast, then it is quite possible that the word silent block is unfamiliar to you, like many other strange names in this area. However, it is an important part of the car's design.
Silent blocks, unfortunately, are more prone to breakage. Of course, we have our roads to thank for this. Replacing this part in Russia will cost you 200-1200 rubles . for one part, and approximately 500-1000 rubles . for the work of replacing it. But first, a little about what it is and how to determine the malfunction.
Lada Granta. Daisies, daisies.
This happened sometime after the new year.
My wife went to a service station to change the oil. When purchasing from them, replacement is free. We have visited this station before, for more than one year. The network is quite famous and has always been distinguished by decent quality of work. Even when I still owned the Peugeot and the official dealer threw up his hands and could not identify the fault, this service center found and repaired the car. That day there was a promotion in the service. Change the oil, get diagnostics as a gift. The oil was changed quickly and diagnostics were carried out. The serviceman comes out and says:
— The car is in perfect order, but the daisies need to be replaced.
“The silent blocks of the front braces need to be changed,” the master corrected, putting his wife into an even greater stupor. If the word daisies was still familiar to her, then silent blocks seemed like a dirty word.
— What is the replacement price including labor and spare parts? - she asked anyway.
“At least five thousand rubles,” the master announces the price tag.
She kindly refused the services of the master, suspecting something was wrong and went home. Already at home she began to torture me about what kind of daisies they were, what their price was and how difficult it was to change them.
Daisies on Grant look like this:
You can see the price of the set. Is a replacement worth 4375 rubles? Of course not! Look, to replace we need a hole, a set of keys, a bucket, a hammer and a chisel or puller. You need to unscrew this bolt:
Next, pull out the saber and you can work with a hammer. The fact is that the metal part of the daisies sticks to the hole and we knock them out with a chisel.
Next, we press in new ones and put everything in place. It's the same on the other side. To do everything about everything, without having pullers, so to speak, on the knee, will take a non-professional no more than an hour of time. The service takes half an hour with smoke breaks. And for this five thousand? A bit fatty! By the way, at the first opportunity, I climbed under the car. The daisies are intact! Not a millimeter to the side! Apparently, the service wanted to raise money easily.
Here is another story from the life of my Lada Granta. Believe it or not. And don’t blindly trust services! All the best and good luck!

How to understand when it's time to replace
Even if you are an inexperienced novice driver, you will be able to diagnose silent block faults by reading this article. It is recommended to perform these simple steps even if you are the happy owner of a new car, and the mileage is very low. The fact is that manufacturers, as a rule, declare a figure of 100,000 km , but in reality it is not even close to that. In real conditions, you can count on 50,000 km in the best case, and if your routes constantly go along terrible roads with bumps and potholes, the life of the “oil seal” may end before the 30,000 km mark. So what are the signs of trouble?
Before you get behind the wheel, inspect the treads on your car's wheels. If they are more worn on one side than the other, this may be a likely sign. The hinge fails, and on the corresponding side the load on the suspension increases significantly.
Then get behind the wheel and start driving. Here the first sign is completely unpredictable behavior of the car. The vehicle skids when cornering, the steering wheel is very reluctant to obey, and there is a constant swaying of the body. Now try driving onto a dirt road. If obvious knocking and vibrations are felt when driving on an uneven surface, there is definitely a malfunction.
Replacing “daisies” (silent blocks of the lever), bushings and stabilizer struts on a Lada Granta
Problems with silent blocks and levers manifest themselves in the form of extraneous sounds, as well as knocks that come into the cabin while driving. Among other things, you can understand that the chassis needs repairs by deteriorating the driving performance of the car, as well as reducing the comfort of movement.
Often, faulty silent blocks or levers are discovered during an attempt to adjust the wheel alignment. If there are malfunctions in the chassis, this adjustment is impossible.
From this article you will learn how to repair the chassis of a Lada Granta, namely: replace the silent blocks of the lever (“daisies”), as well as the struts and stabilizer bushings with your own hands.
For work, it is necessary to prepare new spare parts, as well as a set of keys (“17”, “19”), a vice (press), WD-40 and other auxiliary tools “for every fireman”. It is better to work on a lift or you will have to hang the wheels one by one.
Approximate price level
In Russia, a new set of two racks for the Lada Granta is sold at prices ranging from 3,000 to 13,500 rubles . The cost of sets of different types and brands is shown in the table.
Brand | Country of issue | Type of racks | Price of the set in rubles |
Alternative | Russia | gas-oil, rear, for aggressive driving style | 3390 |
Future technologies | Russia | front, oil, self-adjusting | 5790 |
DEMFI | Russia | gas-oil, rear | 3000 |
SS20 | Russia | oil, front | 8590 |
ASTON | Russia | front, oil | 5890 |
ASOMI | Russia | gas-oil, front | 7000 |
Trialli | Italy | rear, gas | 3400 |
DEMFI | Russia | gas-oil, front, for difficult road conditions | 6900 |
FOX | Germany | front, oil | 3600 |
ATECH | South Korea | front, gas-oil | 4270 |
BILSTEIN | Germany | front, gas | 11500 |
A used set of front or rear struts can be purchased for 1600-2500 rubles .
Used racks
How to replace daisies, stabilizer bushings, stabilizer links on a Grant at home?
- The first thing you need to do is go to the inspection hole if you don’t have a lift. Then remove the engine protection and front wheels.
- Next, we treat all the nuts that need to be unscrewed with WD-40, this will make your “life” easier.
- Then unscrew the anti-roll bar.
- After this, we remove the levers to replace the daisies, although some can be changed without removal. To remove the lever, you need to unscrew three crab mounting bolts, two TORX bolts, ball mountings, and one bolt that secures the lever to the car body.
- Now you need to press out the old ones and press in the new silent blocks; for this you will need a press. As an option, you can use a vice, or a special “device” with which silent blocks are pressed in and pressed in without removing the levers.
Assembly is performed in reverse order.

Daisies on a grant - what is it?
Every car enthusiast tries to pay as much attention as possible to his swallow. We have to change consumables on time and deal with broken parts. If you suspect that the silent blocks of the grant have served their purpose, then you need to quickly drive the car into the pit. It is worth paying attention to the harbingers.
Often there is an incomprehensible dull knock in the suspension either on the right or left. There can be knocking for various reasons, but the silent block of the grant is one of the popular ones. Speaking about the reasons, you can go through the options for a long time, because it could be a support, a rod in a rack, or a box bracket. It is worth paying attention to such a detail as stretching, it is often the cause.
What to do about the knocking?
If you do not pay attention to the problem and do not change the silent blocks on the grant, the knocking will become increasingly stronger. Therefore, it’s time to drive the car into the pit, remove the engine protection, and look at all the details. You can swing the car from the desired side, whether you hear a knock or not, but it will happen if the silent block on the grant has become completely unusable. If the problem is in the stretcher, then you need to pull it too, the resulting knock will be proof that the cause of the breakdown has been found.
You can replace the silent blocks with grants, the price of which seems reasonable, right in the pit, without the need to remove the levers.
Tools required:
1. 2 keys for 24. 2. Extension tubes. 3. Head 17. 4. Thin screwdriver. 5. Punch, it is better to give preference to the canonical one. 6. A hammer, it will hardly be possible to do without it in work when the silent blocks of the grant need to be replaced.
Preparatory measures for replacing the support bearing Do-it-yourself grants
Replacing the support bearing of the Lada Granda strut can be done in two ways. 1. Removing the front strut and unscrewing the wheel alignment bolts. 2. Removing the strut module along with the rotating mechanism and brake disc assembly without unscrewing the adjusting fasteners. Both methods cannot be performed without removing the strut, but using the second method, which is described below, you can avoid another wheel alignment.
Preparation for repair
It is advisable to carry out the replacement in an inspection hole, so you will save time on the convenience of performing operations to remove/install the unit. The car is in first gear; to comply with safety regulations, use wheel chocks.
Tools for work
1. Any jack. 2. Large wrench to remove chassis bolts. 3. Long wrench 30, for the hub nut. 4. Clamps for tightening shock absorbers. 5. Device for removing tie rod ends. 6. Hammer, chisel, core. 7. Set of keys (22, 17, 13). 8. “Ratchets” for 13, 17, 19. 9. Hex key for unscrewing the rod nut. 10. Special heads. "Eshki" E8 and E12. 11. Large “minus” screwdriver. 12. Pliers. 13. Penetrating lubricant, such as WD-40. 14. Torque wrench for tightening the rod nut.
Required set of new parts
— Supports or individual support bearings, depending on the breakdown; — Rubber gaskets (if you only change the bearing); — Boot with cotter pin from steering rod (if replacement is required).
How difficult is the job?
Any novice craftsman can cope with such repairs; the silent block of the grant will be shown in the photo; it is not difficult at all. It is worth doing the work in the following sequence. You need to hold the stretcher with one key, and use the second to unscrew the nut. Now you need to unscrew the 3 bolts that secure the crab, after which replacing the silent blocks of the fret grant involves removing the brace.
The attractive price for the grant silent block will allow you to purchase parts without extra costs. When you try to remove the stretcher, the rubber part may fall out towards you. Please note that the part also has metal clips; you will also have to deal with them. To do this, you can use a screwdriver and a hammer, or take a drift; you can see the work on replacing silent blocks in the video grant.
Summarize
Now you know which racks are best to install. Replacing the shock absorber strut, as well as disassembling it in order to change specific parts, did not turn out to be a complicated procedure. This work can be done by an ordinary Lada Granta owner who has the desire and the tools. Upon completion of the repair work, do not forget to check and adjust the alignment.
Before you begin actual assembly, make sure that all marks are completely aligned with each other. Also be sure to check the angles at which the front wheels of the Lada Grant are installed. If you are convinced of problems, perform a wheel alignment to ensure more reliable operation of the car.

The upper support bearing is an important element in the design of the Granta front strut. The “supports” are involved in the rotation of the front strut during a turn, and also absorb axial loads and provide rigidity to the mechanism. The “support” itself is a housing of two cups, inside of which the bearing itself is located, consisting of a rubber separator with balls inside. It also contains gaskets (vibration and noise insulators). The listed elements, as well as the design of the front support, are presented in the photo.

We install new silent blocks
Now the moment has come when you can install new silent blocks on the Lada Granta, the main thing is to know how to press them in. The landing site will need to be pre-lubricated, you can use graphite lubricant, then the nut is screwed on, the silent blocks of the grant are pressed in, the price for them is not high. In this case, you can do without special devices that allow you to press parts. And you don’t need to remove the lever itself, as some people do.
When you have figured out how to change the silent blocks on the grant, it is worth remembering that after replacing you need to loosen the nut so that you can attach the crab. It must be taken into account that the holes intended for fastening are displaced. So Lada Granta, replacing silent blocks is not complete without a hammer, which is useful for adjusting the holes. It will be necessary to use it on both sides.
After replacing the silent blocks on the grant is completed, you may encounter an amazing effect. Drivers notice that the roughness in steering disappears, the steering wheel becomes more obedient, and the road holds without problems. Therefore, if there is a suspicion that the silent blocks of the front levers of the grant have become unusable, it is better to immediately look for the cause and replace them. As a result, you will receive a machine whose performance will only please you.
Dear customers, in order to avoid errors when sending the front suspension lower arm extension joints, please indicate your car model and year of manufacture in the “Comment” line.
A car suspension is a set of devices that provide an elastic connection between the supporting system and the axles or wheels of the car, reducing dynamic loads on the supporting system and wheels, and damping their vibrations, as well as regulating the position of the car body while driving.
Rubber-metal joints in modern cars play a major role in ensuring the mobility of suspension elements and isolating the body from road noise and vibrations.
Rubber-metal lower control arm joints are used to provide a non-rigid mounting of the lower control arm. Rubber-metal hinges consist of metal cages, between which there is a layer of rubber. Thanks to the rubber gasket, the connection is elastic and dampens vibrations occurring in the suspension. The hard rubber used for the hinge retains its properties at different temperatures. Metal clips serve for a tighter fit of the rubber-metal hinge and prevent the rubber part from touching the lever mount. Rubber-to-metal joints help prevent the transfer of hard shocks from the suspension to the car body, thereby reducing the likelihood of damage to the body and engine when driving on uneven road surfaces. Over time, due to constant exposure to vibration loads, the rubber gasket comes off the metal holder and the rubber-to-metal joint must be replaced, as the suspension arm fastening deteriorates and the effect of damping shock loads disappears.
The suspension, being an intermediate link between the car body and the road, must be light and, along with high comfort, ensure maximum driving safety. This requires precise wheel kinematics, high control information content (not only steering), as well as insulation of the body from road noise and the hard rolling of radial tires (especially with a low profile).
Silent block. A little theory
The purpose of this part can be understood from its name, if you know English. Translated from it, the word “silent” means quiet. Logically, its task is to ensure silent operation of the car’s suspension. This is definitely correct. But the main purpose of the silent block is to eliminate absolutely any vibration that may occur during the operation of the car, and to ensure a quiet, smooth ride, and therefore comfort for the driver and passengers.
By design, this part is a rubber-metal hinge (its second name), consisting of two metal bushings that are connected to each other by a rubber gasket. The location of silent blocks is very diverse. This is a reaction rod, and levers in the front suspension, fixing the rod in the rear suspension, and in addition, the connection of the shock absorber, engine and gearbox.
Operations for removing the front suspension arm of the Lada Granta
We hang the car, remove the wheel from the side where we will remove the lever. Remove the engine protection. We remove the ball joint, see the article “Removing the ball joint from the Lada Granta.” Holding the extension with a 24-mm open-end wrench, use a spanner of the same size to unscrew the extension nut.
Unscrew the bolt securing the link connecting the arm and the anti-roll bar. Often, if the bolts have not been changed or loosened for a long time, they can break. It is best to have spares before removing the lever.
Use a soft metal drift to knock out and remove the bolt. Do not damage the thread.
Using two 19mm wrenches, unscrew the nut of the bolt securing the lever to the body.
We remove (or knock out) the bolt and remove the lever from the bracket.
Remove the washer from the stretcher and remove the lever.
On the extension behind the large washer there are washers for adjusting the pitch angle of the rack's rotation axis (the photo shows three washers, there may be another number)
Clean up the washers and install them back in the same quantity. If the levers are removed from both sides, mark the washers so that they can be installed in their places.
How to remove the spring and shock absorber on a Grant?
- If the vehicle is equipped with an ABS system, then before starting the repair process with shock absorbers and springs, it is imperative to remove the sensor of this safety unit.
- Now you can disconnect the tie rod. This manipulation involves simultaneously disconnecting the tip of the steering mechanism from the swing arm located on the shock-absorbing element.
- To prevent a large error in the installation angles of both Lada Granta wheels, before dismantling it is necessary to mark the location of the upper bolt with a washer, with which the suspension element is attached to the steering axle with its bracket. An ordinary marker can be perfect for this. This simple action will allow you to easily get to the service center in order to subsequently correct the camber and toe. And while driving, the car will not so obviously try to move to the side.
- Unscrew the bolts securing the strut and knuckle. First, we release the upper bolt paired with the eccentric washer, and then remove the lower fastener. Now the time has come to disconnect the strut from the trunnion. We proudly perform this action.
- Let's go back under the hood. We find three points (nuts). This is the attachment point for the shock-absorbing element to the body spar cup. The nuts are unscrewed evenly (one at a time, but by a small amount). This will prevent the rack from skewing. We support the shock-absorbing element itself from the inside of the wheel arch so as not to cause it to fall. The entire event is implemented using the key at “13”.
- Having achieved victory over the nuts, we solemnly remove the stand.
- We use ties for spring elements. The process of clamping the coil with these devices is carried out until the moment when the spring is released from the thrust between the cups of the rack and the support.
- After making sure that the spring is free, use a “22” key to unscrew the central nut of the rod.
- Now let's start disassembling the rack. We dismantle the support with its bearing, remove the upper metal cup and the damping element. All that remains is the boot and the spring itself.
- We inspect all parts for signs of wear or damage.
Replacing silent blocks in the front suspension arm of a Lada Granta
To replace the silent block for attaching the Lada Granta lever, you will need a vice. We press out the silent block with a suitable piece of pipe. We moisten the new silent block with soapy water and press it into the lever, also using a piece of pipe of a suitable diameter.
We knock down the silent block of the extension installation with a chisel. There are two of them, on one side and the other.
Having removed from one side, remove in the same way from the second.
We press the new silent block in a vice...
...and finally press it, striking a punch with a diameter of 8 mm through three windows in the rubber layer. We carry out the assembly in the reverse order. Tightening the threaded connections of all rubber-to-metal hinges of the front suspension arm of the Lada Granta must be done when the car is standing on its wheels, on a flat surface.
Every car enthusiast tries to pay as much attention as possible to his swallow. We have to change consumables on time and deal with broken parts. If you suspect that the silent blocks of the grant have served their purpose, then you need to quickly drive the car into the pit. It is worth paying attention to the harbingers.
