Operation Skoda Octavia Tour In conditions of Russian roads inevitably leads to wear of suspension elements, among which the key place is occupied by the Silent blocks. These rubber metal hinges provide smooth running, extinguish vibrations and hold the geometry of the levers. When they fail, the car begins to behave unpredictably, which directly affects the safety of the driver and passengers.
Many owners Octavia Tour It is mistakenly believed that a knock in the suspension is the verdict of the entire lever in the assembly. In practice, it is often enough to replace only silent blockThis allows you to save a significant amount. However, the replacement process requires a specific tool and knowledge of the nuances of the design of the front and rear beams of this model.
Signs of wear and diagnostics of suspension
The first signal of problems with the Bushings is a change in the nature of driving. If you feel that the steering wheel has become โcoolโ or the car is reluctant to react to turns, you should pay attention to the condition. front control arms. Vibration on the steering wheel when driving on irregularities is also a classic symptom of ruptured rubber insert.
When visually inspecting, pay attention to the presence of cracks, tears or detachment of the rubber from the metal sleeve. Often, rubber simply โdriesโ and crumbles, losing its damping properties. In some cases, you can see oil stains on the rubber part, if a shock absorber flows near the Bushing.
The most reliable way to check is to use a mount. You need to try to move the lever relative to the hub or beam. If the backlash is more than 1-2 mm, the part requires immediate replacement. Ignoring this problem will lead to accelerated tire wear and destruction of other suspension units.
Design features of the Octavia Tour suspension
Suspension Skoda Octavia Tour It has its own unique features that distinguish it from new generations. The front suspension is made according to the McPherson scheme with separate levers, which requires attention to each individual Bushing. The rear suspension is often a twistable beam, where the Bushings are pressed directly into it.
Particular attention should be paid rear silent blocksThey are very busy with the swelling and the slinging. The rubber in these knots has a complex shape and is often reinforced with metal rings. When replacing, it is important to observe the tightening moment of the bolts, which differs from the standard values for other models of the VAG group.
The design of mounting levers to the body also has nuances. In some configurations, bolts with hexagonal heads are used, which can cling to death due to the lack of protection from corrosion. It is recommended to process them in advance. WD-40 or similar means the day before the start of work.
Selection of quality spare parts: original or analogue
Spare parts market for Octavia Tour It is oversaturated with offers, and choosing the right manufacturer is half the success of a repair. Original from Skoda It is usually supplied in boxes with the logo of the concern, but products from brands such as Lemfรถrder or Febi Bilstein are often hidden inside. This is a guarantee of quality, but also a high price.
If the budget is tight, it is worth considering proven alternatives. Brands, like. TRW, Sasic or CTR They offer products that are close to the original. However, one should be careful with Chinese analogues of unknown origin, since their resource can be only 10-15 thousand kilometers.
- โ Lemfรถrder - a standard of quality, often goes like the original.
- โ Febi Bilstein is a reliable German manufacturer with a good price-quality ratio.
- โ Cheap Chinese brands without markings risk rapid failure.
Tools and preparation for replacement
To successfully replace silent blocks, you will need not only a set of keys, but also a specialized tool. A regular jack and wrench won't do the job here. Required press or a set of pullers for silent blocks, which allow you to press out old bushings without damaging the lever.
It is also necessary to have a torque wrench. Suspension bolts must be tightened strictly according to the regulations. For Octavia Tour Tightening torques vary depending on the unit: from 80 Nm to 120 Nm. Violation of these values โโcan lead to thread failure or rapid destruction of the new silent block.
Do not forget to prepare a container for draining technical fluids if you plan to remove elements related to the brake system or shock absorbers. Keeping the work area clean is also important to prevent dirt from getting into the new tires parts during installation.

Step-by-step replacement instructions
Start the process by raising the car on a lift or using secure stands. Remove the wheel and dismantle the elements that interfere with access to the lever. For the front suspension, you will need to unscrew the stabilizer bar mounting bolt and the bolts securing the arm to the subframe.
Pressing out the old silent block is the most labor-intensive step. Use press, placing a suitable mandrel. If the lever cannot be removed, you can carefully knock it off with a hammer, but without fanaticism, so as not to deform the metal. The old silent block often comes out with great effort if it has become stuck.
Before installing a new part, clean the seat from rust and dirt. Lubricate the new tires bushing with a small amount of soapy water or silicone grease - this will make pressing easier. Press the silent block strictly in the center, controlling distortions.
- ๐ ๏ธ Use only a properly functioning hydraulic press.
- ๐ ๏ธ Check the alignment of the mandrel and the lever before starting work.
- ๐ ๏ธ Do not use a hammer to drive in new silent blocks.
โ๏ธ Preparing to replace silent blocks
โ ๏ธ Attention: It is strictly forbidden to tighten the bolts securing the arms while the vehicle is on its wheels and the weight is fully distributed on the suspension. First tighten all the bolts โliveโ, then lower the car to the ground and only after that carry out the final tightening with the required torque.
What if the bolt is stuck?
If the bolt does not come off, try heating it with a torch. Apply a penetrating lubricant and let it soak in for 15-20 minutes. Sometimes a sharp short-term impact with a hammer on the head of the bolt helps to destroy the rust layer. In extreme cases, you will have to use a grinder, but be careful not to damage the threads of the lever.
After installing all parts, carry out a control check. Make sure there are no backlashes or distortions. Clean the suspension from traces of grease and dirt. Finish the job by installing the wheels and lowering the vehicle to the ground.
Wheel alignment after repair
Any intervention in the suspension geometry, especially the replacement of levers or silent blocks, requires mandatory adjustment of the wheel alignment angles. On Skoda Octavia Tour this is critically important, since incorrect camber will lead to uneven tire wear after just a couple of thousand kilometers.
The wheel alignment procedure allows you to restore the correct toe and camber angles, ensuring straight vehicle movement and stable behavior on the track. The technician at the stand will adjust the parameters based on the modelโs factory specifications.
Don't try to save money on this service. Incorrect settings can lead to the fact that even new high-quality silent blocks will fail much earlier than expected due to abnormal loads. Regularly checking suspension geometry extends the life of the entire vehicle.
Save the old silent block after replacement and show it to the wheel alignment specialist. This will help him quickly understand wear patterns and adjust wheel alignment angles based on the real problems of your car.
Comparative table of silent block characteristics
For clarity, letโs compare the main parameters of popular brands used for Octavia Tour. This will help you make informed choices when purchasing parts.
| Brand | Material | Average resource (km) | Price (conditionally) |
|---|---|---|---|
| Skoda (Original) | Rubber/Polyurethane | 80 000 - 100 000 | High |
| Lemfรถrder | High strength rubber | 70 000 - 90 000 | Medium/High |
| Febi Bilstein | Standard tires | 50 000 - 70 000 | Average |
| TRW | Reinforced rubber | 60 000 - 80 000 | Average |
Replacing silent blocks without subsequently adjusting the wheel alignment is a gross mistake that will negate all repair efforts and lead to rapid tire wear.
Polyurethane or rubber: what to choose?
The debate about which material is better continues among owners. Octavia Tour. Factory silent blocks are made of special rubber, which provides maximum comfort and silence. Polyurethane, on the other hand, offers greater rigidity and durability, but transmits more vibrations to the body.
If you like a quiet ride and comfort, it is better to stay on the original tires. Polyurethane only pays off in aggressive driving conditions or on very poor road surfaces, where rubber quickly breaks down. However, please note that polyurethane bushings require more careful maintenance and regular lubrication.
When choosing polyurethane, make sure that the manufacturer includes serviceability. Some models of polyurethane silent blocks do not have lubrication channels, which leads to their rapid jamming. For most Octavia Tour owners, the optimal solution remains high-quality rubber analogues from proven European brands.
Typical repair mistakes
One of the most common mistakes is trying to replace only one silent block on one side. The suspension works as a single system and wear always occurs in pairs. Replacing only one part will create an imbalance in the operation of the suspension and accelerate the failure of neighboring components.
Another mistake is using the wrong tool. An attempt to knock out the silent block with a hammer or pry bar often leads to deformation of the lever or damage to the threads of the bolts. This makes it impossible to properly install the new part and may require replacing the entire lever assembly.
You should also avoid tightening bolts by eye. Even experienced craftsmen can make mistakes with the tightening torque. Use a torque wrench and consult the technical documentation. This guarantees that the silent block will work in the designed mode and will last a long time.
โ ๏ธ Caution: Never use a torch to heat bolts while rubber suspension components or brake hoses are nearby. High temperatures can permanently damage rubber and reduce its strength.
FAQ: Frequently asked questions
How long does it take to replace silent blocks?
The replacement process depends on your experience and tool availability. For one lever, it takes a professional about 30-40 minutes. At home, taking into account preparation and pressing, one car can take from 2 to 4 hours.
Is it possible to drive with damaged silent blocks?
In the short term, yes, but it is dangerous. A damaged silent block changes the suspension geometry, which worsens handling and increases braking distance. Long-term use can lead to destruction of the lever or separation of the suspension while driving.
Do I need to change the entire lever if the silent block is not sold separately?
In rare cases, when the silent block does not have a detachable design or is not sold separately, the lever assembly has to be replaced. However for Octavia Tour Most silent blocks are available as separate parts, which is much cheaper.
How often do you need to check the condition of silent blocks?
It is recommended to carry out a visual inspection at each maintenance (every 15,000 km). A complete suspension diagnostic including checking play should be done every 30,000
