With silent blocks - one of the main elements of the suspension of Volkswagen Polo. Their damage deteriorates the stability and handling of the car, so it is not necessary to postpone the repair "to the best times."
Malfunctions and symptoms
The damage to the suspension elements can be alarmed:
- owls and "Swimming" of the car,
- knock when driving on an uneven road,
- stressed tire wear.
Prevention and diagnostics
Before starting repair, it is necessary to check the condition of all suspension elements. The levers are changing when cracking or deformations are detected, and silent blocks - in cases:
- damage to the ends
- cracking of the rubber array,
- the appearance of breaks or peeling,
- asymmetric rubber release.
Spare parts
All faulty details must be replaced by new ones. If the lever is in excellent condition, you can save on the spare parts, replacing only worn "silent". The front levers of Volkswagen Polo Sedan contain two silent blocks:
- front (smaller size),
- and rear (more massive).
In order not to disassemble the chassis once again, it is better to replace both spare parts at once. The only condition for the long-term operation of the grooved node is good quality and correct installation of new parts.
Order of work
For high-quality and durable recovery chassis, you will need:
- lookout ditch or lift,
- dynamometric key
- machine tool kit,
- fuller ball supports,
- press with a set of mandrels
- stand for checking the corners of the wheel installation.
Not every garage has such a "arsenal", so the best way to restore the suspension will be a trip to professionals.

Silent blocks are a pair of metal sleeves. One of them is internal - the other external. Between them necessarily located insert from polyurethane. Volkswagen Polo suspension is sufficiently worn. Original details serve for a long time, a variety of different analogues are represented on the market. It is necessary to follow the state of the levers, as well as silent blocks.
What is imagined
Silent block suspension lever combines all its main components. In addition, they participate in the work of the shock absorbers.
At the same time, the details are immediately executed a list of various tasks. It is very important to monitor their condition. At the very first faults, it is necessary to replace. First of all, it concerns various abuses. Volkswagen gives a guarantee on this detail about 50 thousand km. As a rule, the original details of this vehicle pass through 60-70 thousand km. But it is important to note that such components may be out of order more often.
It is possible to estimate the status of the part according to the home. It is enough just to raise the car on the lifting or install on the sightseeing pit. The main signs of silent blocks and levers:
- the surface of the sienel block should be without cracks, smooth;
- it is important that the absence of a backlash - when it is presented, the details must be replaced.
The consequences of the wear of silent block can be quite serious. First of all, this reduction of manageability, the car can "throw" from side to side.
There may also be uneven wear of the tires. Therefore, it is important to monitor the proper state of details, if necessary, to replace as much as possible.
Separately, it is necessary to note the question of selecting details for this car. As in all other cases there is always a question of choting between the original part and analogue. The first is an order of magnitude more expensive, but their quality is significantly higher. Moreover, the price of these components is relatively small, the choice must be made in favor of the first. Original parts have a significantly greater resource. What will increase the time until the next replacement.
The cost of silent blocks will be:
The arms themselves, as a rule, there is no need to change. Hold them extremely problematic. When choosing sienel blocks, it must be borne in mind that different manufacturers in different ways denote the details. This applies to, including the guide shooters on the most rubber part. In the absence of experience, it is better to turn to a hundred.
When choosing levers to replace the best solution, a compromise of the ratio price and quality is just VAG. This manufacturer supplies high-quality details that are almost no different from originals.
How is the replacement of silent blocks, levers
After the choice of necessary parts is made, they purchased, you should prepare everything you need for repair work:
- the key with removable end heads - "ratchet";
- heads end numbers: №16; №18; №19;
- washing keys are precipitated: №16; №18; №19;
- the key that allows you to disconnect the fasteners of the wheels - by 17;
- dynamometric key - if possible, but the presence of it is not necessary.
The following examples of the front suspension levers are selected on a concrete example:
- 357 407 182;
- 1J0 407 181.
Selected are analogues from Lemforder, and quite high quality. Do not try to save on such details as silent blocks. The cost of a complete set is not more than 1 thousand rubles, but their failure can cause serious trouble. Separately, you need to stay on the processing process. It will take:
- bolt M12 × 150 mm;
- nut M12 - 2 pcs.;
- the washer reinforced M12 - 2 pcs.
The process itself includes the following main steps:
- it is necessary to put a car on the handbrake, lift it - you can install on supports;
- the next step will be unscrewing the wheels;
- if there is any, it will be necessary to remove the engine protection - as it will interfere with unscrewing bolts - when dismantling the front silent block;
- front wheel mudguards are disconnected - such will also interfere with the dismantling process;
- next, you will need to disconnect the screws for the fastening of the ball support - for this purpose the end head is applied to 16;
- the process is carried out in the following order: unscrew the fastening bolt to the subframe - head to 18; Next, it is necessary to unscrew the rear sieneblock bolt - head 18;
- after performing all operation, it will be necessary to remove the bolts from the holes in the suspension lever;
Next, it will be necessary to remove the front part of the bracket pendant lever. If necessary, the stretch brackets must be cleaned of dirt and corrosion. After that, the front silent block is pressed by a special device. It is actually the most common vice.
Next, after preparation, you must pressent in the Silent block levers. It is important to take into account the essential nuance - when the silent block is pressed, the stop should be laid only on the inner ring. As a result, the work looks like this:
Similarly, the rear silent block is pressed. After the pressing is completed, it will be necessary to install the levers in the reverse order. The replacement process is no different on different versions of the body Volkswagen Polo - sedan, hatchback. It is important to replace silent blocks in a timely manner. Since a serviceable suspension is a guarantee of the car's stability on the road. The appearance of backlays, other problems when managing the vehicle is possible.
